Rolling pool ball

Hume discusses the pool ball and how when the white ball is hit, it is expected to either eventually stop when momentum is lost, or when it hits into another ball. For someone who has experience in playing the game of Pool, they would most likely make this conclusion. But for someone who does not know the game, they will not know what to expect. The ball doesn’t necessarily stop all the time when it hits another ball however. Sometime it just merely rubs against another ball and keeps on rolling past. Either way, whether the ball just bounces from wall to wall, or ball to ball, scientific rule says that it will eventually stop.
