Using the principle of momentum conservation, explain what happens when a moving billiard ball collides with a stationary ball (cue ball hitting the eight ball)


Expert Answer

Step 1


Cue ball hits a eight ball.

Step 2

Conservation of momentum is the direct consecuence of the Newton’s third law of motion. Consider the collision between cue ball and the eight ball. When two balls collide, there is force F on the eight ball due to cue ball, but as per Newton’s third law, the eight ball applies same magnitude of force on the cue ball but in opposi...
