A pendulum clock uses a periodically swinging simple pendulum as its timekeeping element. For small angular displacement, an ideal simple pendulum of length has period . This weak dependence on amplitude at small amplitude makes the simple pendulum useful for producing nearly equal time intervals.
Real friction would stop the swing. An escapement transfers small amounts of energy from a falling weight or wound spring while counting oscillations through a gear train. Changing the effective length changes the rate: increasing increases the period and makes the clock run slower. Temperature-dependent length and finite-amplitude corrections limit the ideal formula.

A pendulum clock is a type of timekeeping device that uses a swinging pendulum to regulate the movement of its gears and keep accurate time. The basic principle behind a pendulum clock is that the regular motion of the pendulum allows for precise measurement of time intervals. ### Key Components of a Pendulum Clock: 1. **Pendulum**: A weight (or bob) attached to a rod or string that swings back and forth.
