How is periodic movement of a pendulum used to make clock​

Answer»

ANSWER:

Periodic motion of a pendulum has been used to MAKE CLOCKS and watches. Motion of objects can be presented in pictorial form by their distance-time graphs. The distance-time graph for the motion of an object moving with a constant speed is a straight line.

Explanation:

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.
