Force is a push or pull that causes motion or changes the motion of an object. Forces act between two interacting objects. The motion of objects is caused by the action of a force - for example, a magnet attracts iron due to the force of attraction. A push is when one object exerts a force to move another object away, while a pull is when an object exerts a force to move another object towards itself. Forces can add up if acting in the same direction or subtract if acting in opposite directions. The strength and direction of a force determines its effect.

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.
Friction
Forces can be pushes or pulls and have both size and direction. They are measured in Newtons and can be determined by adding all forces acting on an object together. Most objects experience multiple forces, some acting together and some opposing each other, creating either balanced or unbalanced forces. Friction is a force that resists the relative motion of surfaces in contact and can be either useful, like providing traction, or harmful, like causing overheating. It is measured through sliding, rolling, and static varieties.
Force motion-magnetism
The document discusses physics concepts related to forces and motion. Part 1 covers forces, including defining a force, balanced and unbalanced forces, and Newton's laws of motion. Part 2 discusses motion concepts such as position, speed, velocity, and how to calculate speed. Key ideas are that forces cause motion or changes in motion, and that balanced forces result in no net force while unbalanced forces do result in a net force and acceleration.
Force and Motion- Sci. 8
1. The document discusses Isaac Newton and his work on motion and forces. It explains Aristotle's view of motion requiring force versus Galileo's view that objects naturally continue in motion without force.
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. Contact forces like applied force, normal force, and friction oppose motion while gravity acts from a distance.
3. Free body diagrams use arrows to represent all forces acting on an object and their magnitudes and directions to analyze motion. Friction opposes the relative motion between two surfaces in contact.
Chapter 9 class 9
1. Forces can change the motion of an object by moving it from rest, changing its speed or direction. Balanced forces do not change motion while unbalanced forces do.
2. Friction opposes the motion of objects over a surface, causing rolling objects to slow down and stop. Galileo's experiments showed that unbalanced forces are needed to change an object's motion but not to maintain uniform motion.
3. Newton's Second Law states that applying a force to an object will cause it to accelerate, with a greater force producing greater acceleration. Momentum is the product of mass and velocity, and inertia is an object's resistance to changes in its motion.
FORCE ppt.pptx
Forces can be contact forces, like pushing or pulling, or non-contact forces, like magnetic or gravitational forces. A force is an interaction that causes an object to move or change shape. Forces can put objects in motion from rest, change the speed or direction of a moving object, or deform an object by stretching or compressing it. There are different types of forces including contact forces like friction and muscular force, and non-contact forces like magnetic, electrostatic, and gravitational forces.
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.

Newton's laws of motion describe the relationship between an object and the forces acting upon it, and its motion in response to those forces. The three laws are: 1) An object at rest stays at rest and an object in motion stays in 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, in the direction of the net force. 3) For every action, there is an equal and opposite reaction.
force and laws of motion
1. Forces can change the motion of objects by moving stationary objects, changing the speed or direction of moving objects, or deforming objects. Balanced forces do not change motion while unbalanced forces do.
2. Galileo's experiment on inclined planes showed that an object's speed increases going down a plane and decreases going up, demonstrating the effects of forces on motion.
3. Newton's second law states that applying a force to an object causes it to accelerate, and the greater the force or mass, the greater the acceleration. Newton's third law says that every action has an equal and opposite reaction.

1. The document summarizes Newton's laws of motion and key concepts in mechanics like force, balanced and unbalanced forces, inertia, momentum, and conservation of momentum.
2. It explains that force can change the motion of an object by changing its speed, direction, or state of rest. Balanced forces do not change motion while unbalanced forces do.
3. Newton's three laws of motion are outlined as the first law describing inertia, the second law relating force and acceleration, and the third law stating that every action has an equal and opposite reaction.

Newton's third law states that for every action, there is an equal and opposite reaction. It means that in any interaction between two objects, there are always two forces of equal magnitude acting in opposite directions. Examples given are a person pushing on a refrigerator, which results in the refrigerator pushing back with an equal force, and a horse pulling on the ground while the ground pushes forward on the horse with the same amount of force.
Force and laws of motion By R K Chaudhari
1) Force is any external agent that causes an object to change its motion. Newton's three laws of motion describe the relationship between force and motion.
2) Newton's first law states that an object will remain at rest or in uniform motion unless acted upon by an external force. This tendency of objects to resist changes in motion is called inertia.
3) 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.
8 Force and pressure PPT.ppt
This document discusses force, pressure, and their related concepts. It defines force as a push or pull on an object due to the interaction between objects. It explains that the net force on an object is the sum of all forces if in the same direction, or the difference if in opposite directions. Forces can cause motion, changes in speed or direction, or deformation of objects. There are two main types of forces - contact forces like friction and muscular force, and non-contact forces like magnetic, electrostatic, and gravitational. Pressure is defined as the force per unit area, so a smaller area results in a greater pressure for the same force. Liquids and gases exert pressure on their containers that depends on factors like height and
VIII-11-Force and pressure.ppt
This document provides information about force and pressure. It defines force as a push or pull on an object that can be caused by the interaction between two objects. It describes how the net force on an object is calculated if two forces act in the same or opposite directions. Forces can make objects move, change speed or direction, stop, or change shape. There are two main types of forces - contact forces that occur through direct contact between objects, and non-contact forces that act over a distance like magnetic, electrostatic, and gravitational forces. Pressure is defined as the force applied over an area, and gases and liquids can exert pressure on containers depending on factors like height and area. Atmospheric pressure is also explained.

Speed is how fast an object moves in a given direction, while velocity includes both speed and direction. Average speed is the total distance traveled divided by the total time taken, while average velocity is the displacement divided by the time interval. Acceleration is the rate of change of velocity with time and is caused by an unbalanced net force acting on an object. Forces can be contact forces or non-contact forces, and examples include tension, normal force, gravitational force, friction, and others. Balanced forces cause no change in an object's motion, while unbalanced forces cause acceleration and a change in motion.
Force and preesure
This document provides self-learning material on forces and pressure. It contains definitions of key terms like force, pressure, contact forces, non-contact forces. It describes how forces can cause objects to move, change speed or direction of motion. Experiments are presented to demonstrate that forces can also change the shape of objects. Specific forces like muscular force, magnetic force, electrostatic force, atmospheric pressure are discussed. Diagrams and activities help explain these concepts.

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.
Conservation Of Momentum
The document discusses collisions and the law of conservation of momentum. It provides examples of how to use a momentum table and algebra to solve for unknown velocities in collision problems involving isolated systems where momentum is conserved. Specifically, it works through examples of a person catching a medicine ball on ice and of two people colliding on an ice rink to determine their combined velocity after collision.

This document discusses different types of forces. It defines force as a push or pull on an object that can be caused by the interaction between two objects. There are two main types of forces - contact forces that occur when objects touch, and non-contact forces that act over a distance like magnetic, electrostatic, and gravitational forces. Contact forces include muscular force and friction. Non-contact forces are illustrated by examples of magnetic, electrostatic, and gravitational interactions. The document also discusses how multiple forces combine into a net force, and how forces can affect an object by changing its motion, speed, direction, or shape.
Newton's Laws of Motion
This document discusses Newton's laws of motion. It begins by defining dynamics as the relationship between motion and the forces that cause it. It then explains that Newton's laws of motion are the fundamental principles of classical mechanics. The document goes on to define key concepts such as force, mass, and inertia. It proceeds to explain each of Newton's three laws of motion - the law of inertia, the second law relating force and acceleration, and the third law of action and reaction. Several examples are provided to illustrate the laws. The document concludes by presenting five assignment problems applying Newton's laws.
Newton's 3 laws of Motion
Sir Isaac Newton discovered the three laws of motion in the late 1600s. 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 force on an object equals its mass times its acceleration. Newton's Third Law states that for every action, there is an equal and opposite reaction.
Laws of motion
This document provides an overview of concepts in mechanics including:
1) Forces, linear momentum, the three laws of motion, inertia, impulse, friction, and conservation of momentum.
2) Uniform circular motion, centripetal force, centrifugal force, and equilibrium of concurrent forces.
3) Steps for solving mechanics problems including drawing free body diagrams and applying Newton's laws. The document is authored by five individuals and contains examples and explanations of key mechanics concepts.

The forces acting on the box are:
1. Applied force (Fa) by the boy pulling the rope towards the right.
2. Frictional force (Ff) by the floor on the box opposing the motion towards the left.
3. Normal force (Fn) by the floor on the box perpendicular to the surface.
To determine the resultant force, we add the forces acting on the same line of action (towards the right and left).
Fa - Ff = Resultant force
Since Fa is greater than Ff, the resultant force is towards the right. Therefore, the box will accelerate towards the right direction as the net force is unbalanced to the right.

The document is labeled as episode 8 and focuses on trigonometry problems.
Rational Inequalities
This document discusses solving rational inequalities and the wavy curve method. It explains that rational inequalities involve fractions with real number coefficients and natural number exponents. It provides the example of (x-1)(x-2)>0 and explains the solution set is between the critical points of x=1 and x=2. It also discusses using the wavy curve method to determine the solution sets of rational inequalities, which involves drawing a wavy curve above the number line that passes through critical points and indicates whether sections are positive or negative.
Intervals
This document provides definitions and examples of different types of intervals in mathematics including open intervals, closed intervals, and semi-closed or semi-open intervals. It defines open intervals as not including the endpoints, closed intervals as including both endpoints when finite, and semi-closed intervals as including one endpoint but not the other. Examples are given for each type of interval using inequalities to represent membership in the set.
Ratio and Proportions
This document provides an overview of ratios and proportions based on the NCERT syllabus for JEE Maths B2A. It defines ratio as quantities of the same kind represented by A:B or the fraction A/B, and defines proportions as equal ratios such that a:b = c:d. It lists important properties of proportions including the product of extremes equals the product of means and inverse, alternate, componendo, and dividend properties. It then transitions to solving equations and inequalities related to ratios and proportions.

It defines key terms such as prime numbers, composite numbers, co-prime numbers, and twin prime numbers. Examples are given for each type of number. The document also discusses properties of integers, rational numbers, and irrational numbers. It provides questions to test understanding of different number concepts covered.
Force and pressure - state of motion
The document discusses the effects that forces can have on objects. It states that a force can change an object's speed by either increasing or decreasing it depending on whether the force is applied in the same or opposite direction of the object's motion. A force can also change an object's direction of motion or shape. However, a force does not always result in a change in an object's state of motion, as experience shows that sometimes applying a force does not change an object's motion. Forces are also categorized as either contact forces, which require physical contact, or non-contact forces, which act over a distance.
Force and pressure - Pressure
Pressure is defined as force per unit area. It is exerted by both liquids and gases on the walls of their containers. Atmospheric pressure is caused by the weight of air in the atmosphere and it is very large, as demonstrated by the force needed to remove a sucker from a surface or the inability of eight horses to pull apart evacuated hemispheres. The human body can withstand this pressure because internal and external pressures are equal.
Force and pressure - kinds of forces
Force can be defined as a push or pull that causes an object to be in motion or attempt to change its motion. There are several different types of forces including contact forces like muscular and frictional forces, and non-contact forces like magnetic, electrostatic, and gravitational forces. Muscular force allows humans and animals to perform physical tasks, while friction always acts opposite to an object's motion and eventually stops rolling objects. Magnetic force causes attraction or repulsion between magnets without contact, and electrostatic force allows charged objects to influence each other at a distance. Gravitational force is responsible for all objects being pulled toward Earth and other massive bodies.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

- 2. Current Affairs 1.Low cost Covid 19 unit 'COVIRAP' which was approved by ICMAR was developed by which institution? (a)IIT-Chennai (b)IIT Khargpur (c)AIIMS (d) JIPMER
- 3. Why?... What?... How?... What do you do to make a football move? What do you do to make a moving ball move faster? How does a goalkeeper stop a ball? How does a football player changes the direction of the moving ball with their legs?
- 4. Force – A push or a pull To move an object, it has to be pushed or pulled. In science, a push or a pull on an object is called a force. Thus, the motion imparted to objects was due to the action of a force. A magnet attracts a piece of iron towards it. Is attraction also a pull? What about repulsion between similar poles of two magnets? Is it a pull or a push?
- 6. A car being pushed by a man
- 7. who is pulling and who is pushing? Click here for Simulation
- 8. Who is pulling whom? At least two objects must interact for a force to come into play. Thus, an interaction of one object with another object results in a force between the two objects.
- 9. Exploring Forces In this game two teams pull at a rope in opposite directions. The team that pulls harder, that is, applies a larger force, finally wins the game.
- 10. Forces applied on an object in the same direction add to one another. If the two forces act in the opposite directions on an object, the net force acting on it is the difference between the two forces. (In the tug-of-war when two teams pull equally hard, the rope does not move in any direction.) A force could be larger or smaller than the other or equal to each other. The strength of a force is usually expressed by its magnitude. We have also to specify the direction in which a force acts. Also, if the direction or the magnitude of the applied force changes, its effect also changes. Exploring Forces
