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
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
What is Force? 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? Force causes
