Pendulum clock: History, Gravity-swing pendulum & Mechanism

A pendulum clock is a clock that uses a swinging weight known as a pendulum as its timekeeping element. The pendulum is an approximate harmonic oscillator that swings in a time interval that depends on its length, and that resists swinging at other rates. From its invention in 1656 by Christiaan Huygens, inspired by Galileo Galilei, until the 1930s, the…
