ลูกบอล

Also known as balls

A ball is a round object (usually spherical, but sometimes ovoid) with several uses. It is used in ball games, where the play of the game follows the state of the ball as it is hit, kicked or thrown by players. Balls can also be used for simpler activities, such as catch or juggling. Balls made from hard-wearing materials are used in engineering applications to provide very low friction bearings, known as ball bearings. Black-powder weapons use stone and metal balls as projectiles.

AI overview

A ball is a round object, typically sphere-shaped, that serves many purposes from sports and recreation to industrial applications. Balls are central to games like football and baseball where players hit or kick them, but they're also used in simpler activities like catch and juggling, as well as in engineering as low-friction ball bearings and historically as projectiles in weapons.
