Pool Ball

Pool ball refers to the spherical objects used in the game of pool (billiards), typically made from materials like resin or phenolic. There are 16 balls in standard play: one cue ball (white) and 15 object balls, divided into striped and solid categories, numbered 1–15. These balls are struck with a cue stick on a rectangular table with pockets, aiming to legally sink them into pockets according to game rules. The design and behavior of pool balls involve principles of physics, such as momentum, spin, and collision, influencing gameplay strategies.
