Chapter 06 Momentum
... We have already established that in order to change the momentum of an object, an unbalanced force must be applied. If you are riding in a car, and you push against the inside of the door; does the car accelerate in the direction of your force? No, Newton’s third law says that your force on the door ...

Answer: The logic is that Action and Reaction always act on different bodies, so they can not cancel each other. When we push a massive ...
