Note that Euler's Disk would spin & roll forever if it were not for friction and vibration.

Conservation of Energy

When Euler's Disk is spun, the disk contains both potential and kinetic energy. The potential energy is given to the disk when it is placed upright on its side. The kinetic energy is given to the disk when it is spun on the mirrored base.

Angular Momentum

Like a top, Euler's Disk uses its angular momentum to hold itself upright. As the disk spills around in a circle it is held in place by a balance of the gravitational force pulling the disk down and the force applied by the mirror base which holds the disk up.
