billiard ball

Numbered pool sphere

A billiard ball is one of the hard, smooth spheres used in billiards, pool, or snooker—struck with a cue stick to knock other balls into pockets or against cushions.

The balls are typically made of resin and precisely weighted for consistent play.

Figuratively, billiard balls represent perfect elastic collision in physics problems, or anything that ricochets predictably: The idea bounced around his head like a billiard ball.
