This is a demonstration of the dependence of the angular acceleration on the moment of inertia. A hoop and a disc of the same radius are both released at the same time on an inclined plane, and roll to the bottom of the plane.
This demonstration was created at Utah State University by Professor Boyd F. Edwards, assisted by James Coburn (demonstration specialist), David Evans (videography), and Rebecca Whitney (closed captions), with support from Jan Sojka, Physics Department Head, and Robert Wagner, Executive Vice Provost and Dean of Academic and Instructional Services.
