When I play pool, why doesn't the ball go where I want it to?
by Mrs. Healy
What happens in a pool game is based entirely on physics (Newton's Laws).
Before you start playing pool, all of the objects are at rest. They stay at rest until a force is acted upon them. When you hit the cue ball with the pool cue, a force makes the ball begin to move. The cue ball can then hit one of the other balls. Depending on the angle at which the cue ball strikes the other ball, the ball will move in different ways. In order to make sure that the solid or striped ball goes where you want it to, you need to understand the laws of motion. Mastery of the game of pool is really mastery of physics and angles.
