What happens when two moving objects collide?

Newton’s third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).

Why do pool balls turn yellow?

Pool balls made out of phenolic resin will turn yellow over time. This yellowing is caused by exposure to UV light, heat, and the air causes the phenolic resin to break down, which gives the ball an offwhite appearance.

Why does a billiard ball at rest move when hit by a moving billiard ball?

2. Every action has an equal and opposite reaction: Our brains are hard wired to conceptualize that the moving ball hits the stationary ball. If fact, they both hit each other with the same force. This means that the moving ball stops and the stationary ball moves with the speed of the moving ball that hit it.
