Wiktionary

  1. pendulum(Noun)

    A body suspended from a fixed support so that it swings freely back and forth under the influence of gravity, commonly used to regulate various devices such as clocks.

  2. Origin: Neuter of pendulus, "hanging".

Webster Dictionary

  1. Pendulum(noun)

    a body so suspended from a fixed point as to swing freely to and fro by the alternate action of gravity and momentum. It is used to regulate the movements of clockwork and other machinery

  2. Origin: [NL., fr. L. pendulus hanging, swinging. See Pendulous.]

Freebase

  1. Pendulum

    A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When released, the restoring force combined with the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth. The time for one complete cycle, a left swing and a right swing, is called the period. A pendulum swings with a specific period which depends on its length. From its discovery around 1602 by Galileo Galilei the regular motion of pendulums was used for timekeeping, and was the world's most accurate timekeeping technology until the 1930s. Pendulums are used to regulate pendulum clocks, and are used in scientific instruments such as accelerometers and seismometers. Historically they were used as gravimeters to measure the acceleration of gravity in geophysical surveys, and even as a standard of length. The word 'pendulum' is new Latin, from the Latin pendulus, meaning 'hanging'. The simple gravity pendulum is an idealized mathematical model of a pendulum. This is a weight on the end of a massless cord suspended from a pivot, without friction. When given an initial push, it will swing back and forth at a constant amplitude. Real pendulums are subject to friction and air drag, so the amplitude of their swings declines.

  1. Pendulum

    pen′dū-lum, n. any weight so hung from a fixed point as to swing freely: the swinging weight which regulates the movement of a clock: a lamp, &c., pendent from a ceiling: a guard-ring of a watch by which it is attached to a chain.—adj. Pen′dular, relating to a pendulum.—v.i. Pen′dulate, to swing, vibrate.—adjs. Pen′dulent, pendulous; Pen′duline, building a pendulous nest; Pen′dulous, hanging loosely: swinging freely, as the pensile nests of birds: (bot.) hanging downwards, as a flower on a curved stalk.—adv. Pen′dulously.—ns. Pen′dulousness, Pen′dulosity.—Pendulum wire, a kind of flat steel wire for clock pendulums.—Compensation pendulum, a pendulum so constructed that its rod is not altered in length by changes of temperature; Compound pendulum, every ordinary pendulum is compound, as differing from a Simple pendulum, which is a material point suspended by an ideal line; Invariable pendulum, a pendulum for carrying from station to station to be oscillated at each so as to fix the relative acceleration of gravity; Long and short pendulum, a pendulum for determining the absolute force of gravity by means of a bob suspended by a wire of varying length. [L., neut. of pendulus, hanging—pendēre, to hang.]
