On 16th May, 1669,

Robert Hooke demonstrated that a long pendulum with a heavy bob could be maintained in motion by a small force, such as that of a pocket watch, and that in this way a pendulum could be kept going with a very narrow arc of swing. In Hooke’s demonstration the pendulum was 14 feet long, whereas in the present reconstruction of his experiment, due to Mr. M. C. Aimer, FBHI, it is 12 feet long.

[edit] How it works

When a pendulum is displaced from its resting equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When released, the restoring force will cause it to oscillate about the equilibrium position, swinging back and forth. The time for one complete cycle, a left swing and a right swing, is called the period.
