Ball

A ball is a round, usually spherical but sometimes ovoid, object with various 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, marbles and 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.

Famous quotes containing the word ball:

    Will TV kill the theater? If the programs I have seen, save for “Kukla, Fran and Ollie,” the ball games and the fights, are any criterion, the theater need not wake up in a cold sweat.
    Tallulah Bankhead (1903–1968)

    Innings and afternoons. Fly lost in sunset.
    Throwing arm gone bad. There’s your old ball game.
    Cool reek of the field. Reek of companions.
    Robert Fitzgerald (1910–1985)

    It may be possible to do without dancing entirely. Instances have been known of young people passing many, many months successively, without being at any ball of any description, and no material injury accrue either to body or mind; Mbut when a beginning is made—when felicities of rapid motion have once been, though slightly, felt—it must be a very heavy set that does not ask for more.
    Jane Austen (1775–1817)
