This document discusses Isaac Newton's three laws of motion and their applications. Newton's first law states that objects at rest stay at rest and objects in motion stay in motion unless acted on by an unbalanced force. Newton's second law establishes that force equals mass times acceleration (F=ma). Newton's third law describes that for every action there is an equal and opposite reaction. Examples are provided to demonstrate these laws, such as how gravity causes apples to fall from trees and how objects with different masses accelerate at the same rate but with different forces due to their mass.

Force and motion
Forces and motion are discussed in this document. It defines a force as a push or pull and explains that all motion is due to forces acting on objects. Motion is defined as a change in an object's position over time. Balanced and unbalanced forces are compared, with unbalanced forces being able to cause motion. Common forces like gravity, friction, and air resistance are described. Examples are provided to illustrate key concepts around forces.
Forces
A force is any influence that causes an object to change its movement, direction, or shape. Forces can make an object begin moving, change speed or direction of motion, or cause a flexible object to deform. There are two main types of forces: contact forces, which act between objects in direct contact, and non-contact forces, which act over a distance. Contact forces include normal forces, friction, and tension. Non-contact forces include gravitational, electric, and magnetic forces. Newton's laws of motion describe how forces cause motion or changes in motion.
newton's laws of motion
- Sir Isaac Newton formulated his three laws of motion in his book Philosophiae Naturalis Principia Mathematica published in 1687.
- Newton's First Law states that 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.
- Newton's Second Law states that 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.
- Newton's Third Law states that for every action, there is an equal and opposite reaction.
Work and Energy
The document discusses various physics concepts related to work, energy and power including:
- The definition of work in physics and the formula to calculate work.
- Kinetic energy and its formula. Kinetic energy depends on an object's mass and velocity.
- Gravitational potential energy and its formula. Gravitational potential energy depends on an object's mass, height above ground, and gravitational acceleration.
- The principles of conservation and conversion of energy. Energy cannot be created or destroyed, it can only change form.
Phy 7 velocity and acceleration ppt
This document provides examples of calculating speed, velocity, acceleration, and deceleration using formulas involving distance, time, and change in velocity. It defines key terms like speed, velocity, and acceleration. Examples include calculating the speed of a car accelerating from 0 to 1609.36m in 25.9 seconds and decelerating from 60 mph to a stop over 6 seconds. Graphs of velocity over time are also presented and examples are given of interpreting the graphs to determine acceleration, deceleration, and distance traveled.
Force.Ppt
Force is a push or pull that can cause motion or acceleration. It is measured in Newtons and all forces are interactions between objects. The net force is calculated by adding forces in the same direction and subtracting forces in opposite directions, with an unbalanced net force producing motion.
Balanced and unbalanced forces
Forces can be either balanced or unbalanced. Balanced forces are equal forces acting in opposite directions, causing no change in an object's motion. Unbalanced forces are unequal forces acting on an object, always causing a change in its motion such as making it move, stop, or change direction. The document provides examples of activities that demonstrate balanced and unbalanced forces and explains the key differences between the two types of forces.
Forces
This document discusses different types of forces. It explains that gravity, the ground, air, and your own body exert forces on you at all times. Forces can cause objects to move, change speed or direction. Gravity pulls objects down, while surfaces push up. Friction opposes motion and can slow or stop objects. Net force is calculated by adding or subtracting different forces on an object. Balanced forces result in no motion, while unbalanced forces cause motion.

Forces
The document describes various concepts related to forces including:
1) Different types of forces such as magnetic, weight, tension, contact, and friction forces.
2) The effects of forces including changing an object's motion, speed, direction, shape, and putting a stationary object into motion.
3) The relationship between net force, mass, and acceleration given by F=ma.
4) How to calculate weight, distinguish it from mass, and how it depends on gravitational strength.
Work and power
Work is defined as a force causing an object to move in the direction of the force. No work is done if there is no movement. More work is required to do a task quickly than slowly. Power is the rate at which work is done and is calculated by dividing the amount of work by the time taken. Work is being done on objects when a force moves them in the direction of the force.
Law of interaction
1) Newton's third law of motion states that for every action, there is an equal and opposite reaction.
2) Whenever one object exerts a force on a second object, the second object exerts an equal but opposite force back on the first object. These paired forces are called action-reaction force pairs.
3) Examples of action-reaction force pairs include a rocket exhaust pushing down on gases which push back up on the rocket with an equal force, and a car tire pushing down on the road surface while the road pushes back up on the tire.
Ppt Gravity
The document discusses the law of universal gravitation and gravity. It states that all objects with mass exert gravitational attraction on each other, and that the gravitational force depends on the masses of the objects and the distance between them. It also explains that while the Earth exerts a force we can feel, we cannot feel the force of nearer objects like desks because their force is smaller due to lower mass and closer proximity.
Forces Newton’s Laws
The document discusses Newton's laws of motion and forces. It explains that balanced forces cause no acceleration, while unbalanced forces cause acceleration proportional to force. Newton's first law states that an object remains at rest or in constant motion unless acted on by an unbalanced force. Newton's second law allows calculating acceleration from mass and unbalanced force using F=ma. Centripetal force provides the unbalanced force needed for circular motion.
Types of forces
This document discusses different types of forces. It begins by explaining that moving objects are said to be in motion. It then states that a push or pull acting on an object is called a force. The document goes on to list and briefly describe four main types of forces: gravitational force, magnetic force, nuclear force, and muscular force.
Forces gr.7
Mass is the amount of matter in an object and is measured in grams. A force can change the position, speed, direction, or shape of an object. Weight is the pull of gravity on an object and is measured in Newtons. There are two types of forces - contact forces which act when objects touch, and non-contact forces which act over a distance like magnetic or gravitational forces. Balanced forces cancel each other out while unbalanced forces cause changes in speed or direction.
Kinetic energy
This document discusses kinetic energy, which is the energy an object possesses due to its motion. Kinetic energy depends on an object's mass, as it is directly proportional to mass, and also on an object's speed, as it is directly proportional to the square of the speed. An example is provided that an object with a mass of 1 kg moving at 1 m/s has a kinetic energy of 0.5 Joules. The document is presented by Aswathy K. at FMTC Pallimukku.
Classification of waves
1. The document classifies waves into two main categories: mechanical waves and electromagnetic waves.
2. Mechanical waves require a medium to propagate and can be longitudinal or transverse, while electromagnetic waves can travel through a vacuum.
3. The electromagnetic spectrum arranges all types of electromagnetic waves from gamma rays to radio waves based on their frequency and wavelength. It includes gamma rays, X-rays, UV light, visible light, infrared, microwaves and radio waves.
Forces
Force is a push or pull that can be described by its strength and direction. There are two types of forces - contact forces like friction that require touching, and non-contact forces like gravity and magnetism. The net force on an object is the combination of all individual forces acting on it. Forces can be balanced or unbalanced. Common forces acting on objects include gravity, friction, and the normal force.
Work, energy & power physics
This document covers concepts related to work, energy, and power. It begins by defining work as the mechanical transfer of energy due to external forces, and is equal to the product of the force and the displacement in the direction of the force. Various examples are provided to illustrate situations where work is and isn't being done. The relationship between work and energy transfer is explained. Kinetic and potential energy are introduced, and analogies are provided. Methods for calculating work, energy, and power are demonstrated through examples.
Momentum
Momentum is a characteristic of moving objects related to its mass and velocity. It is calculated by multiplying mass and velocity, with units of kg*m/s. An object's momentum is in the direction of its velocity, and greater momentum means it is harder to stop the object. Both greater mass and velocity result in higher momentum. The total momentum in a system is conserved during interactions and collisions according to the law of conservation of momentum.
Newton's first law of motion
Newton's First Law of Motion states that 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. An unbalanced force is a net force that is not equal to zero and causes a change in an object's velocity. Balanced forces have no net force and do not cause a change in velocity, while unbalanced forces have a non-zero net force and do cause a change in velocity. Examples are given of how friction and collisions can cause changes in motion by introducing unbalanced forces.
Turning effects of forces physics presentation for 9th grade Physics students...
The moment of a force is a measure of its turning effect. For an object to be in equilibrium, the forces acting on it must be balanced and the turning effects of the forces must also be balanced. The moment of a force is calculated by multiplying the force by the perpendicular distance from the pivot to the force.
Force and Motion
1) Sir Isaac Newton studied motion and is best known for his laws of motion and universal law of gravitation.
2) Forces can cause objects to start or stop moving, change direction, or maintain constant motion depending on whether the net force is balanced or unbalanced.
3) Friction opposes the motion of objects in contact and depends on factors like the nature of the surfaces and the pressing force between them. It exists as both static and kinetic forms.
30 p.13.2 net forces ppt (3) (1)
Forces can be either balanced or unbalanced. Balanced forces are equal opposing forces that do not cause a change in an object's motion. Unbalanced forces are unequal opposing forces that produce a change in an object's motion. A net force is the sum of all forces acting on an object. An object will accelerate in the direction of a net force.
Energy, Work & Power
The document discusses energy, work, and power, defining these concepts and how they relate. It explains that energy can be converted from one form to another but is never created or destroyed according to the law of conservation of energy. Assessment tasks are provided to evaluate understanding of energy transfer and transformation within closed systems.

This document discusses force and motion. It defines force as a push or pull that causes an object to change its motion. It lists several types of forces: air resistance, applied, spring, frictional, gravitational, electrical, normal, and magnetic. For each force it provides a brief definition. It defines motion as a change in an object's position over time. It explains that balanced forces result in no motion, while unbalanced forces can change an object's motion. The net force on an object is the combination of all individual forces acting on it. Gravity is defined as the force of attraction between all objects, depending on their masses and distance between them.
Newton’s Laws of Motion with Real Life Examples
Newton's first law states that 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. It is also known as the law of inertia. Examples given are a hockey puck slowing down due to friction on the ice and a kicked ball in space continuing forever without air resistance or gravity. Newton's second law explains that acceleration is produced by an unbalanced force acting on an object, with greater force needed to accelerate objects with greater mass. Pushing a truck requires more force than pushing a car. Newton's third law states that for every action there is an equal and opposite reaction, such as a boat moving backward when a person jumps
Newton´S Third Law Of Motion
Newton's third law of motion states that for every action, there is an equal and opposite reaction. Whenever two objects interact, they exert forces on each other - the forces are called action and reaction forces. Birds are able to fly because as they push down on the air with their wings, the air pushes up on their wings with an equal and opposite force that provides lift. When a baseball hits a bat, the bat pushes the ball in the opposite direction of the force exerted by the ball on the bat.

Sir Isaac Newton developed his laws of motion in 1665 at the age of 23. The first law, 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 second law, the law of acceleration, states that acceleration is produced when a force acts upon a mass, and greater force is needed to accelerate greater masses. The third law, the law of interaction, or action-reaction, states that for every action there is an equal and opposite reaction.

Newton's three laws are summarized as: (1) an object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force, (2) force causes acceleration that is proportional to the mass of the object, and (3) for every action there is an equal and opposite reaction. Forces are categorized as contact forces, which require physical interaction, and non-contact forces like gravity and magnetism. Examples of different contact and non-contact forces are also provided.
Flash formula forces
This document defines and explains key concepts related to forces and motion, including that a resultant force is needed for an object to accelerate, and that if forces balance out there is no acceleration. It also covers that an object's weight is equal to its mass times the gravitational acceleration, and how air resistance can balance out weight at terminal velocity resulting in constant speed.

Newtons laws of_motion - 2nd law
The document discusses Newton's second law of motion, which states that the net force on an object is equal to its mass times its acceleration (F=ma). It provides an example calculation of using the formula to find the net force required to accelerate a 1400 kg car. It also defines that one newton is the force needed to accelerate 1 kg of mass by 1 m/s2. Gravity and its relationship to the second law is discussed, where gravitational force Fg equals mass times gravitational acceleration of 9.8 m/s2. Several example problems are provided to check understanding of applying the second law.
Chapter 3 forces
This unit discusses the effects of forces. It defines force as a push or pull and explains that forces can change an object's shape, motion, and direction of motion. It then introduces Newton's three laws of motion - the first law states that 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. The second law states that acceleration is directly proportional to net force and inversely proportional to mass. The third law states that for every action there is an equal and opposite reaction. Examples are provided to illustrate each law.

This document provides information about Newton's laws of motion. It defines Newton's first law of motion as stating that 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. Examples are provided to illustrate the first law. Newton's second law is defined as relating the acceleration of an object to the net force acting on it. Equations for momentum, force, and acceleration are also presented. Newton's laws of motion are described as accurately modeling motion except when dealing with very high speeds near the speed of light or very small objects like atoms, which require relativistic or quantum mechanics, respectively.

The document discusses Newton's three laws of motion:
1) An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force. Friction causes moving objects to slow down.
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. The forces acting between two interacting objects are equal in magnitude but opposite in direction.

This document provides information about Newton's Three Laws of Motion:
1) Newton's First Law of Motion (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 in the same direction unless acted upon by an unbalanced force. Friction is given as an example of a force that can cause an object in motion to slow down and stop.
2) Newton's Second Law of Motion (Law of Acceleration) states that the net force on an object equals its mass times its acceleration (F=ma). Examples are given to demonstrate how acceleration depends on mass and net force.
3) Newton's Third Law of Motion
Newton's second law of motion
- Sir Isaac Newton published his three laws of motion in 1687 in his book "Philosophiae Naturalis Principia Mathematica", establishing the laws of motion that describe how objects move.
- Newton's second law states that the acceleration of an object depends on the net force acting on the object and its mass, such that acceleration is directly proportional to net force and inversely proportional to mass.
- The equation for Newton's second law is: Force = mass x acceleration (F=ma), where the SI unit for force is the Newton.

The document discusses Newton's second law of motion, which states that the force exerted on an object is equal to its mass times its acceleration (F=ma). Several examples are provided to demonstrate how to use the equation to calculate force, mass, or acceleration when two variables are known. The relationship between force, mass, and acceleration is explored through problems involving objects like skiers and elevators accelerating under different conditions.

Lesson 2 Motion and Conservation Laws.ppt
This document provides an overview of motion and conservation laws. It begins by explaining Aristotle's conception of motion as natural or violent, then Galileo's rejection of the idea that a force is needed to maintain motion. It then covers Newton's three laws of motion and uses them to explain why objects fall at the same rate regardless of mass. The document also discusses conservation of mass, energy, and momentum. It provides examples of applying the laws of conservation to collisions and gravitational interactions.
newtons_laws_of_motion.ppt
Newton's three laws of motion are summarized as follows:
1) First law - 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. Friction is the main force that causes objects to slow down.
2) Second law - 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) Third law - For every action, there is an equal and opposite reaction. Whenever two objects interact, they apply forces to each other of equal magnitude but opposite direction.

Forces
The document discusses different types of forces including gravitational, electromagnetic, weak nuclear, and strong nuclear forces. It also covers Newton's three laws of motion, defining inertia, mass, weight, net force, and friction. Key concepts are that mass is a measure of an object's quantity of matter independent of gravity, while weight depends on gravity. Newton's second law states that force equals mass times acceleration, and his third law is that for every action there is an equal and opposite reaction. Friction opposes motion between surfaces in contact.
