### Pushing a car, Newton’s 3rd Law and Friction

Pushing a car and Newton’s third law Hope you have seen people pushing their car when it’s not starting due to some issue. When someone is pushing a car or something like that, he first pushes the ground or floor backwards with his feet. Following the ‘3rd law of Newton‘ the ground also exerts an equal

### Free fall, Acceleration due to Gravity and Kinetic Energy

Weight of any object is a force applied on the object by earth’s gravitational pull towards the center of the earth. We know the equation of a force = mass * acceleration. i.e.      F=m*a…….(1) When we talk of weight force then the equation becomes like this: Weight(W)= mass * acceleration due to gravity

### Force – Basic Concepts of Physics

Force is a push or pull. If you are pushing a box, you are certainly applying a force. If you are pulling a rope you are again applying a force. As a force is applied on a body, it results into an acceleration of the body. Now what is acceleration? Acceleration is the rate of
