Science 8 module 1 day 2 balance unbalanced force
This document discusses forces, balanced and unbalanced forces, and calculating resultant forces. It defines a force as a push or pull and notes they have both magnitude and direction. Balanced forces are equal in size but opposite in direction, resulting in no change in motion. Unbalanced forces cause a change in motion, with the net force being the difference between forces and pointing in the direction of the larger force. Examples of calculating resultant forces from unbalanced forces are provided.
June 6 science 8 balanced and unbalanced force
This document provides a lesson on balanced and unbalanced forces. It defines forces and explains that balanced forces occur when forces cancel each other out, resulting in no movement. Unbalanced forces happen when one force is stronger, causing a change in motion. The lesson compares balanced and unbalanced forces, gives examples of applying forces in daily life, and includes reading activities and a quiz to reinforce understanding.
P6 Forces
Forces are pushes or pulls that cannot be seen but can be detected through their effects such as making stationary objects move, changing the speed or direction of moving objects, slowing or stopping moving objects, and changing the shape of objects. There are different types of forces including gravitational, elastic spring, frictional, and magnetic forces. Gravitational force is the force of attraction between objects with mass. Elastic spring force stores energy when compressed or stretched and releases it to return the spring to its original shape. Frictional force slows and stops moving objects when they contact another surface. Magnetic force can be either attractive or repulsive depending on the object and magnet.
EFFECTS OF FORCE IN OUR DAILY LIFE DONE BY AKHIL MADISHITTI
This document discusses forces and examples of forces used in everyday life. It defines a force as a push or pull that can change an object's motion. There are two types of forces: contact forces and forces that act over a distance. Examples of different forces given are gravitational, electric, magnetic, nuclear, and frictional forces. The document then provides examples of how forces are used in everyday activities like opening doors, pushing or pulling objects, kicking a ball, and applying brakes to stop a vehicle. It explores how forces change the motion of objects and their effects.
Push N Pull
A force is a push or pull that can change an object's shape, size, and motion. Forces cause arrows to push into targets, athletes to push finishing lines as they reach them, and basketballs to push through nets. Forces can move stationary objects, change the speed or direction of moving objects, stop moving objects, and change an object's shape.
Pushes and pulls g2
This document introduces the concepts of pushes, pulls, and forces. It defines a force as a push or a pull that causes an object to move or change direction. Gravity is identified as a specific force that pulls objects toward Earth. The objectives are to understand how far different objects can move, define forces and gravity, and recognize different ways that objects can move, such as in straight lines, curves, circles, or zigzags.
Push and pull
Forces can be pushes or pulls that either start an object's motion, change how fast or slow it is moving, alter its direction, or stop its movement. A push is a force moving something away, while a pull brings something closer. Common examples are closing a door by pushing it, kicking a ball with a pushing force, and using a screwdriver by pulling or pushing.
Force
This document provides information about force and motion. It defines a force as a push or pull and notes that all forces have magnitude and direction. It then gives several examples of the effects of different forces, such as an arrow hitting a target. The document discusses that a force can change an object's shape, size, and motion. It also defines types of motion, speed, velocity, acceleration, and summarizes Newton's Three Laws of Motion.

Push and pull
Push and pull are forces that can make objects start or stop moving, slow down or speed up, change direction, or alter shape. Forces have the ability to initiate or halt an object's motion, modify its speed, redirect its path, or transform its form. Push and pull forces impact objects in a variety of ways including setting them in motion, bringing them to a standstill, altering their velocity, and changing their configuration.
Science Year 2: Push and Pull
This short document discusses how pushing and pulling can be used to move objects, change their shape, and change their direction. It notes that pushing, pulling, and pushing and pulling together are actions that can achieve these effects on objects.
Balanced and unbalanced force
This document defines and provides examples of balanced and unbalanced forces. It states that balanced forces occur when two forces of equal magnitude act in opposite directions, resulting in no acceleration. Unbalanced forces occur when forces are not equal, resulting in acceleration in the direction of the larger force. Examples given include a book at rest on a table with balanced forces, and an object accelerating downwards or horizontally due to unbalanced gravitational and contact forces.
4. unbalanced forces
This document discusses balanced and unbalanced forces through examples like a boat floating in water, a tug of war, and a moving car.

Sehs 4.3– biomechanics ii (4.3.3, force, com)
The document discusses the fundamentals of biomechanics, including forces and levers. It defines a force as a push or pull that acts on an object, and can be quantified by both magnitude and direction. Forces can be contact forces, which require touching the object, or long-range forces like gravity that act without contact. Levers are rigid bars that rotate around a fulcrum, and there are three classes of levers that differ based on the relative positions of the fulcrum, effort, and resistance. The center of mass of an object can change based on factors like body position, external loads, and age or sex, and affects an object's stability.
RASHMI R A
This document defines force as something that causes an object to move, change speed or direction, or alter shape. It notes that while forces cannot be seen, their effects can be felt and observed. The document then lists several types of forces, including air resistance force, applied force, spring force, frictional force, gravitational force, electrical force, normal force, and magnetic force. It provides a brief definition for each type of force.
Dynamics 1 - Forces
The document discusses forces and dynamics. It introduces Sir Isaac Newton, who defined the three laws of motion. Dynamics looks at what causes motion by examining forces. Forces can be balanced or unbalanced. A balanced force results in no acceleration, while an unbalanced force results in acceleration in the direction of the net force. The effect of forces on an object's motion depends on whether the force and velocity are in the same direction, opposite directions, or at an angle to each other.
Lesson 1
Forces and motion are explored, including definitions of force, momentum, and their relationship. A force is a push or pull resulting from object interaction. There are contact forces like friction and tension, and fundamental forces of gravity, electromagnetism, and the strong and weak nuclear forces. Momentum is defined as mass times velocity. Force and momentum are related vectors, where applying a force changes an object's momentum over time according to the equation F=p/t. Examples and challenges are provided to illustrate these concepts.
Science Grade 8 Teachers Manual
This unit discusses force, motion, and energy. It has six modules that describe energy transfer at both the macroscopic and particle levels. Module 1 focuses on how unbalanced forces cause changes in motion. Module 2 explains how force can do work and transfer energy. The unit aims to develop students' understanding that energy is transmitted through various means and can cause changes in objects. Most topics are dealt with qualitatively to provide a basic understanding of concepts.
1 discoveringnewtonslaws
Sir Isaac Newton discovered the three laws of motion in the late 1600s. The laws describe how objects move and the forces that cause changes in motion. The first law states that objects at rest stay at rest and objects in motion stay in motion unless acted on by an unbalanced force. The second law states that force equals mass times acceleration. The third law states that for every action there is an equal and opposite reaction. Newton published his laws in his influential book "Philosophiae Naturalis Principia Mathematica". His laws remain fundamental principles in physics.
Iramma Amaragol
Force is defined as anything that causes an object to move, change speed or direction, or deform shape. A force can make an object move, change direction or speed, or alter its shape. There are several types of forces including gravitational, electrical, magnetic, air resistance, applied, spring, frictional, and normal forces. Each force has a distinct cause and effect - for example, gravitational force attracts objects with mass, while frictional force is present in daily life whenever objects rub against each other.

Science g8 student l earner s manual final
1. Forces can cause objects to be in motion, accelerate, decelerate, or change direction. An object remains at rest or maintains a constant velocity only when the forces acting on it are balanced.
2. Balanced forces occur when two or more forces on an object are equal in magnitude but opposite in direction, so they cancel each other out. Unbalanced forces cause a change in an object's motion.
3. Examples of balanced forces include the tension and gravity forces acting on a hanging object, and the normal and gravity forces acting on an object resting on a surface. Unbalanced forces, like a push or the presence of friction, can cause objects to start or stop moving.
Science G8 TG
This unit discusses force, motion, and energy over six modules. Module 1 focuses on how unbalanced forces cause changes to an object's motion. Module 2 explains how force can do work on an object and transfer energy. The unit aims to develop student understanding of these concepts qualitatively and through measurements. Key ideas are that energy transfers between objects in different forms, and that the amount and type of energy transfer depends on the materials involved and can cause changes in objects.
K to 12 - Grade 8 Science Learner Module
1) Students conducted an experiment to determine the relationship between force and acceleration by pulling a cart with varying numbers of rubber bands (1, 2, 3, 4) and measuring the cart's acceleration using a ticker tape timer.
2) Analysis of the ticker tape charts showed that as the number of rubber bands increased, representing greater force, the length of the strips increased, indicating higher average velocity over time intervals.
3) This demonstrated a direct relationship between the net force acting on an object and its acceleration, as described by Newton's second law of motion.
Force
Forces can be balanced or unbalanced, where balanced forces produce no motion and unbalanced forces produce motion; Newton's Three Laws of Motion define how forces cause changes in motion, such as how an applied force results in a change in momentum proportional to that force and acting in the direction of the force, and how every action has an equal and opposite reaction. Forces are measured in Newtons and examples include forces from fingers opening a book, magnets attracting, and gravity holding up objects.

Engineering science lesson 1
Here are the key points about momentum and impulse:
- Momentum is the product of an object's mass and velocity. It represents the amount of motion an object has.
- Impulse is the product of force and the time over which it acts. It represents the change in an object's momentum due to a force.
- Impulse and change in momentum are directly related - a large impulse (large force or long duration) results in a large change in momentum.
- Both momentum and impulse are vector quantities, having both magnitude and direction associated with the motion or force.
So in summary, momentum describes the amount of motion, while impulse describes the force applied to change an object's motion and momentum.
Waves and vibrations
This document defines and classifies waves, describing mechanical and electromagnetic waves. It explains that mechanical waves require a medium and can be longitudinal or transverse. Longitudinal waves involve compression and rarefaction, while transverse waves involve up-and-down or side-to-side motion perpendicular to the propagation direction. The document also describes key characteristics of waves like wavelength, amplitude, frequency, period, and how to calculate wave speed using wavelength and frequency. An example is provided of students conducting a slinky experiment to study how variables affect wave speed.
3. vibration and waves
This document is the introduction to Chapter 1 of a textbook on vibrations and waves. It discusses how vibrations are fundamental to nature and perception. Repetitive motion is common due to conservation laws, and waves were discovered to be more fundamental than particles. It defines key terms like period, frequency, and amplitude used to describe vibrations. It gives an example of how conservation of energy requires a carnival game involving a rolling ball to have periodic, repetitive motion rather than a non-repeating path.
Motion(position and velocity)
This document discusses different types of motion including:
- Motion is defined as a change in an object's position over time.
- Position is relative to an origin point and can be positive or negative.
- Types of motion include rectilinear, circular, and periodic motion.
- Velocity refers to an object's speed and direction of motion.
Mechanical Waves
This document discusses waves and the electromagnetic spectrum. It defines a wave as the transfer of energy through a medium without transferring matter. There are two main types of waves - transverse waves, where the medium moves perpendicular to the direction of energy transfer, and longitudinal waves, where the medium moves parallel to the direction of energy transfer. The document also discusses key wave properties like wavelength, frequency, velocity, amplitude, reflection, refraction, diffraction, interference, and resonance.
What is motion and its types
Objects move by changing their position or location over time. There are several types of motion including up and down, straight line, round and round, zigzag, and back and forth motions as seen in examples like a seesaw moving up and down, an object moving in a straight line, a merry-go-round moving in circles, and a swing moving back and forth.
What is a Wave-Physics
Waves transport energy through a medium and do not transport matter. They are caused by vibrations or oscillations within a medium. There are two main types of waves - transverse waves, where the medium moves perpendicular to the direction of energy transport, and longitudinal waves, where the medium moves parallel to the direction of energy transport. The key characteristics of waves include their amplitude, wavelength, frequency, and period. Frequency refers to the number of oscillations per second, while period is the time for one full oscillation. Mechanical waves require a physical medium to travel through and include water waves and sound waves.
Planning your music video lesson 1
This document provides guidance to students on planning a music video for the song "Heartlines" by Florence + The Machine. It instructs students to analyze the song lyrics to inspire a video idea, brainstorm at least 3 video concepts, and begin pre-production planning by creating storyboards for their selected concept. The planning should include schedules, budgets, location permits and other documentation. Students will then present their idea and storyboard to peers to provide feedback before continuing development next week. The goal is for students to apply their knowledge of pre-production to fully plan a music video idea.
Electronic & communication
This document discusses the basics of electronic communication. It defines communication as the process of exchanging information between two parties. It describes two types of signals - analog and digital. It also outlines the basic components of a communication system including the input transducer, transmitter, communication channel, receiver and output transducer. The document discusses noise as an unwanted disturbance in communication systems and lists different types of internal and external noise. It also defines simplex, half-duplex and full-duplex communication systems and provides examples of applications for each type.
Physics-CIRCULAR MOTION
This document discusses circular motion and its two types: uniform and non-uniform. Uniform circular motion describes an object moving in a circle at a constant speed, with the velocity vector always tangent to the circular path. An example given is keeping a car's speed steady around a curve. Non-uniform circular motion involves a changing velocity magnitude, as when a car's speedometer reading changes during a turn. For an object to undergo circular motion, a force must be exerted towards the center of the circle.

Motion Pictures Presentation
Animated films were introduced after 1896 and included clay puppets and cut-out animations. Thomas Edison and Edwin Porter produced one of the earliest films in 1901 showing a comic scene. The Library of Congress began collecting motion pictures in 1893. In the 1920s, silent films were popular and played with live orchestral music. Some notable silent films included The Parade in 1919 and The Kid in 1921 starring Charles Chaplin. The Jazz Singer in 1929 was one of the first widely distributed sound films and also the first musical film to win an Oscar.
Motion Pictures
Motion pictures involve the projection of a series of still photographs that give the illusion of continuous movement when viewed rapidly in succession. They have evolved from early experiments with devices like the zoetrope to modern cinema. Documentaries aim to relay real events while experimental films play with the medium's capabilities. Fictional films are based on imagined characters and stories. Motion pictures can intensely hold viewers' attention, show intimate details, and give an impression of being everywhere at once through camera movements. They have advantages like drawing attention, showing past events, and serving large audiences, but also disadvantages like fixed pacing and potential for misinterpretation.
Motion, speed and velocity
Motion can be described by displacement, distance, velocity, acceleration, time, and speed. There are several types of motion including translatory, rotatory, oscillatory, vibratory, periodic, non-periodic, rolling, random, multiple, rectilinear, curvilinear, uniform, and non-uniform motion. Translatory motion occurs when every point of an object moves the same distance in the same time, and can be rectilinear or curvilinear. Rotatory motion occurs when every point on an object moves around a central axis. Oscillatory motion is the to-and-fro motion of an object about a fixed point.

MODULE 1.pptx
This document introduces forces and motion. It reviews concepts from grade 7 like displacement, speed, velocity, and acceleration. It states that most motions involve non-uniform changes caused by forces. The document previews Newton's Three Laws of Motion and how they will be applied. Key questions are presented about the relationship between forces and motion, rest, and changes in velocity. Students are asked to consider what causes motion and differences in speed. They are given examples to think through involving applying or resisting forces to make objects move, change speed, stop, or alter direction.
Science 8 module 1 Forces and Motion
This module introduces forces and motion. It discusses how forces cause changes in an object's motion, including starting and stopping motion, acceleration, deceleration, and changing direction. Newton's Three Laws of Motion will be presented and applied. Key questions the module will address are how forces relate to motion, conditions for different types of motion, and how force relates to acceleration. Forces can either be contact forces, which act on objects in direct contact, or non-contact forces, which act at a distance.
Forces notes 1 &2
The document discusses the concept of forces. It defines a force as a push or pull that can affect an object's motion by making it start or stop moving, move faster or slower, change direction or shape. Forces are measured in Newtons and usually act in pairs. Common forces include gravity, electricity, and magnetism. Vectors can be used to represent the direction and magnitude of a force. The document also introduces Newton's First Law of Motion and the concept of inertia.
Energy
Most activities involve energy in different forms. Sound, light, heat, and chemical/mechanical energies are used from waking up until moving around. Forces like gravity, wind, water, electricity, and magnetism can push or pull objects to cause motion. Motion is the change in position of an object due to force. Forces can make objects move, change their speed and direction of movement, stretch or compress, or cause up and down motion through balanced or unbalanced opposing forces.

Force notes chap.2 1 slideshare
A force is a push or pull that can be described by its strength and direction. Forces are measured in Newtons. A net force is the combination of all individual forces acting on an object, determining its speed and direction of motion. Unbalanced forces produce a net force causing motion, while balanced equal forces in opposite directions produce no net force and no change in motion.
What is a Force?
A force is a push or pull that can be described by its strength and direction. Forces are measured in Newtons. A net force is the combination of all individual forces acting on an object, determining its speed and direction of motion. Unbalanced forces produce a net force causing motion, while balanced equal forces in opposite directions produce no net force and no change in motion.
Force and motion remind (2)
Newton's three laws of motion describe the relationship between forces and motion:
1) An object at rest stays at rest and an object in motion stays in motion with the same speed and direction unless acted upon by an unbalanced force.
2) The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force.
3) For every action, there is an equal and opposite reaction.
FORCES AND MOTION.pptx
Forces can cause objects to be in motion, change motion, or remain at rest. A force is a push or pull that acts on an object. Forces have magnitude, direction, point of application, and line of action. Balanced forces cause no change in motion, while unbalanced forces cause a change in motion. Common forces include tension, normal force, gravity, friction. An activity is described where students observe and analyze forces on objects at rest like a hanging pen or book being pushed.
Forces notes 1 and 2
The document discusses forces and their effects. It notes that forces can make objects start or stop moving, move faster or slower, or change direction or shape. Forces are usually measured in Newtons and act in pairs. The document also discusses how forces affect the motion of objects, either by changing their speed, direction, or both. It provides examples of contact and non-contact forces like gravity, electricity, and magnetism. Finally, it introduces the concepts of net force and Newton's First Law of Motion.
ScienceShare.co.uk Shared Resource
Newton's three laws of motion are summarized as follows:
1) An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
2) The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
3) For every action, there is an equal and opposite reaction.
Newton’s first law of motion
This PowerPoint presentation discusses Newton's First Law of Motion. It defines force as what causes objects to move, and identifies two types of forces - pushes and pulls. Forces can be balanced or unbalanced, with balanced forces resulting in no motion and unbalanced forces resulting in motion. Newton's First Law, also known as the Law of Inertia, states that an object at rest stays at rest and an object in motion stays in motion with the same speed and direction unless acted upon by an unbalanced force. The presentation provides examples of inertia and discusses how mass relates to inertia.
Force , Newton's Laws of Motion and Momentum
This document discusses Newton's laws of motion and key concepts in mechanics including force, inertia, momentum, and conservation of momentum. It provides examples of balanced and unbalanced forces. The three Newton's laws are explained: 1) an object remains at rest or in uniform motion unless acted upon by an unbalanced force, 2) the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, and 3) for every action, there is an equal and opposite reaction. Examples are given to illustrate momentum, inertia, and conservation of momentum. Multiple choice and short answer questions from an NCERT textbook are also included.
SCI8_NLC_LESSON1.pptxSCI8_NLC_LESSON1.pptx
This document presents a lesson on balanced and unbalanced forces. It begins with key ideas that net force is the sum of all forces acting on an object. If forces are balanced, there is no net force and the object will not move. If forces are unbalanced, there is a net force and the object will move. The lesson then reviews concepts of balance and force in everyday and scientific terms. It provides examples of representing balanced forces and presents activities with questions about force diagrams and the relationship between forces and motion. The conclusion asks students to reflect on what they learned.
Force and motion in Kepler's planetaries
An unbalanced force is needed to change an object's motion. Balanced forces occur when the net force is zero and there will be no motion. Unbalanced forces occur when the net force is greater than zero, causing motion. An object's mass affects its inertia, with more massive objects being harder to move or change the speed/direction of. Gravity and friction also affect motion, with gravity providing a downward force and friction opposing motion between surfaces. Students conduct a penny lab investigating these concepts through balanced and unbalanced forces on a penny.

physics ppt and force and its types
A force is anything that causes an object to accelerate by pushing or pulling on it. Balanced forces have equal magnitudes acting in opposite directions, resulting in no net force and no acceleration. Unbalanced forces do not cancel out, leaving a net force that causes an object to change its motion, such as starting to move, speeding up, slowing down, or changing direction. The standard unit for measuring force is the Newton.
Section 1
A force is defined as a push or pull that can be measured in Newtons. Multiple forces can act on an object simultaneously, and the combination of all these forces is called the net force. An unbalanced net force causes an object to change its motion by starting, stopping, or changing direction, while a balanced net force where forces are equal on both sides results in no movement. The document then introduces an activity involving balloon rocket races.

June 3 lesson 1 science 8
- 2. Quarter 1 Unit 1 Module 1: Forces and Motion
- 3. Questions to ponder! • What makes objects move the way they do? • Why do objects move in different ways? Why are some objects faster than the other? • What makes objects stay in place?
- 4. Lesson 1: Forces • Objectives • 1. Explain the concept of force; • 2. Describe how force affect the movement of objects; • 3. Give the importance of force in daily life.
- 5. Activity • Will this object move by itself? • How can we make this object move? • While it is moving, how can we make the object speed up or slow down? • How can we make it stop? • How can we make it change its direction?
- 7. What is a force? • A force is a push or pull that causes an object to move, stop, or change direction • In physics a force is anything that makes an object move
- 8. • The objects move, speed up, slow down, stop or change its direction because it has to be pushed or pulled. • The motion of an object can be changed if we apply force on it. What is a Force?
- 9. What is a Force? • Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction.
- 10. Think again! • Consider again this ball here on top of the table. Since this ball stays at rest (meaning does not change its motion) can we say that there is/are no force/s acting on it?
- 11. Values Integration • Why do we need force? • Where can we use force? • What are the applications of force in everyday life?
- 12. Assignment • Differentiate balance and unbalanced forces. • Reference: Science Textbook
