1. Pendulumnoun

   Any weight hung so as that it may easily swing backwards and forwards, of which the great law is, that its oscillations are always performed in equal time.

   Etymology: pendulus, Lat. pendule, Fr.

   Upon the bench I will so handle ’em,
   That the vibration of this pendulum
   Shall make all taylors yards of one
   Unanimous opinion. Hudibras.

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 acting on 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. The period depends on the length of the pendulum and also to a slight degree on the amplitude, the width of the pendulum's swing. From the first scientific investigations of the pendulum 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. The pendulum clock invented by Christiaan Huygens in 1658 became the world's standard timekeeper, used in homes and offices for 270 years, and achieved accuracy of about one second per year before it was superseded as a time standard by the quartz clock in the 1930s. Pendulums are also used in scientific instruments such as accelerometers and seismometers. Historically they were used as gravimeters to measure the acceleration of gravity in geo-physical surveys, and even as a standard of length. The word pendulum is new Latin, from the Latin pendulus, meaning hanging.

1. pendulum

   A pendulum is a weight suspended from a pivot so that it can swing freely back and forth under the influence of gravity. Typically, a pendulum consists of a string, chain or beam with a weight at the end, and when challenged from its equilibrium position, it will oscillate or swing in regular periods. It is often used in timekeeping mechanisms such as grandfather clocks, and for various scientific experiments and applications.

1. Pendulumnoun

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

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.

   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′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.]
