When the wheel is rotated by hand to the top and released, its potential energy will turn into kinetic energy (rotation) as it falls. After the wheel reaches its bottom position, the kinetic energy will change back to potential energy when it moves up again. This process will continue on until the total energy is lost due to friction.

The 175-gram solid metal rotor has a moment of inertia of about 2 x 10-5 kgm2. The gyroscope is mounted on a gimbal ring and comes with two stands, one with a rotating frame and the other with rocker feet. A 60-cm starting cord and handle are also supplied. Highly recommended for the classroom setting!
