FAQ:

Q: How is the Euler’s disk like a top?

A: Angular Momentum: Another way of describing how Euler’s Disk operates is by considering the disk’s angular momentum. Like a top, Euler’s Disk uses its angular momentum to hold itself upright. As the disk spolls 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…

Q: Why is a mirror base used for an Euler disk?

A: The mirror base provides a low-friction surface; its slight concavity keeps the disk from “wandering” off the surface. Any disk, spun on a reasonably flat surface (such as a coin spun on a table), will exhibit essentially the same type of motion as an Euler Disk, but for a much shorter time.

Q: How is potential and kinetic energy related to Euler’s disk?

A: 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.

Q: What did Peter Fisher do on Euler’s disk?

A: The quest to achieve longer and longer spin times led him to invite MIT professor Peter Fisher onto the show to experiment with the problem.
