Galileo figured that out straight away and though he never actually managed to build a complete pendulum clock. read more

You need to keep time. In grandfather clocks the time keeping is done by the pendulum which swings to and fro, and one oscillation has a fixed time period. These days the swinging pendulum in this type of clocks is a mere show piece for decoration purposes only. It does not keep time. read more

Some clocks use a spring rather than a weight to store the energy but otherwise the mechanism is the same. Inside the clock the gears are continually advanced on each pendulum swing. The gear ratios are designed to convert the swing time into the desired rotation time for the hands on the clock face. read more

A pendulum clock is a clock that uses a pendulum, a swinging weight, as its timekeeping element. The advantage of a pendulum for timekeeping is that it is a harmonic oscillator; it swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates. read more
