Galilej also has established the law on which there are pendulum fluctuations. It has appeared that the period of fluctuations does not depend on amplitude. This property of pendulums has received the name izohronnosti. It has found a parity between the periods of pendulums of various length, having shown, using gruziki from lead and a stopper that this period does not depend on weight though fluctuations of a pendulum with gruzikom from a stopper fade faster.

Galilej has entered representation about a resonance, having shown that the amplitude of fluctuations of a heavy pendulum can be increased gradually if to blow on a pendulum in a step with its movement. Having arranged a nail on a way of a thread of a pendulum, he observed movement of a pendulum with the reduced length of a thread and has proved that cargo always reaches heights from which it has started to move. This Galilej has laid the foundation for our representations about kinetic and potential energy.

The Result received by Galileem, already at that time had direct practical value. For example, doctors for measurement of pulse of patients have taken advantage of it. He has given the chance to create the mechanism for regulation of a course of hours, and thanks to it they have been made.
