1) When the golf club hits the golf ball some of its momentum is transferred to the golf ball. The golf club slows down and the golf ball speeds up.

2) yes because it is moving the same speed.

3) The cue ball hits the other billiard balls and the cue ball slows down decreasing the momentum, but the billiard balls speed up and their momentum increases.

4) The law of conservation of momentum enables the speed of the objects to be calculated after the collision and will move in the opposite direction the force came from.
