The physical principles of how a yule works are related to the laws of conservation of momentum and energy. As the yo-yo rotates, momentum is conserved and kinetic energy is converted into potential energy and back. In order to control the yo-yo, you must be able to distribute your body weight correctly and control the movement of your arms.
For many centuries, the volcano had no practical application. Nowadays, specially designed spinner (gyroscopes) are the most important part of a number of devices in aviation, navy and artillery.

The most important role in the development of the theory and practice of the gyroscope belongs to Russian scientists - S. Kovalevskaya, N. Zhukovsky, A. Krylov, S. Chaplygin and others.

Volchoks may be quite different from each other. However, all of them have, as established from experience, important properties.

Try to set the spinner vertically. You will not succeed - it will immediately fall sideways.

But give the spinner the fastest rotation - and it becomes stable. Even knocks and clicks will not knock down the spinning spinner. As soon as the spinning stops, the stability is broken.

This is one of the main properties of the spinner. The axis of a rapidly spinning undulator is stable and almost stationary in space.
