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.

Although many types of balls are today made from rubber, this form was unknown outside the Americas until after the voyages of Columbus. The Spanish were the first Europeans to see bouncing rubber balls (albeit solid and not inflated) which were employed most notably in the Mesoamerican ballgame. Balls used in various sports in other parts of the world prior to Columbus were made from other materials such as animal bladders or skins, stuffed with various materials.

As balls are one of the most familiar spherical objects to humans, the word "ball" is used to refer to, or to describe, anything spherical or near-spherical.

Famous quotes containing the word ball:

    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)

    The world was a huge ball then, the universe a might harmony of ellipses, everything moved mysteriously, incalculable distances through the ether.
    We used to feel the awe of the distant stars upon us. All that led to was the eighty-eight naval guns, ersatz, and the night air-raids over cities. A magnificent spectacle.
    After the collapse of the socialist dream, I came to America.
    John Dos Passos (1896–1970)
