DRD02 - Angular Momentum, Rolling Ring and Disc

Objective:

- To illustrate the dependence of angular acceleration on the moment of inertia.

Apparatus:



Method:

If the disc and ring are released together at the top of the plane, the disc will arrive at the bottom of the plane first since its moment of inertia (l/2 mr2) is half that of the ring (mr2). The disc and ring are of equal mass.
