1L20.17 Orbits in Hemisphere

A ball rolling in a transparent glass hemisphere will precess in a predictable manner.

 

A small ball rests in the bottom of a spherical glass jar that is at least 30 centimeters in diameter. A camera is set to film or project the behavior of the ball once it is set spinning in the jar.

Set up is shown above with video camera to show class.
