Many sources     claim that the 10th-century Egyptian astronomer Ibn Yunus used a pendulum for time measurement, but this was an error that originated in with the British historian Edward Bernard. This image is ineligible for copyright and therefore is in the public domainbecause it consists entirely of information that is common property and contains no original authorship. Here K is the complete elliptic integral of the first kind defined by. In a clock, the pendulum must receive pushes from the clock's movement to keep it swinging, to replace the energy the pendulum loses to friction. In addition, it could be recreated at any location at which the gravitational acceleration had been accurately measured. This has a CTE of around 0.

From the first scientific investigations of the pendulum around by Galileo Galileithe regular motion of pendulums was used for timekeeping, and was the world's most accurate timekeeping technology until the s.

When a pendulum is The period of swing of a simple gravity pendulum depends on its length, the local strength of gravity, and to a The period of the pendulum was picked off by reflecting the image of an electric spark created by a precision. A simple gravity pendulum is an idealized equation which represents the motion of a simple pendulum is.
Or more concisely by the substitution.
Suspension springs of Elinvar were used to eliminate temperature variation of the spring's restoring force on the pendulum. Lewis Simplifying assumptions can be made, which in the case of a simple pendulum allow the equations of motion to be solved analytically for small-angle oscillations.

File:Simple pendulum From Wikipedia, the free encyclopedia. Jump to Notepad icon This vector image was created with a text editor. A pendulum is a mass (any object usually metal) on an arm.
The arm is attached to a pivot, which is a point to swing from. The mass will naturally hang down.
Huygens had discovered in that a pendulum has the same period when hung from its center of oscillation as when hung from its pivot,  and the distance between the two points was equal to the length of a simple gravity pendulum of the same period. Pendulum motion appears in religious ceremonies as well.
