A ball is rolling straight across the floor until Bradley kicks it. is this newton's first law, 2nd law or third?

Answer 1

This situation is an example of Newton's first law, also known as the law of inertia. This law states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and direction, unless acted upon by an external force. In this case, the ball was already rolling straight across the floor and would continue to do so unless Bradley's kick acted as an external force to change its motion.
