Which Reaches the Bottom First?
Solbes, Jordi; Tarin, Francisco
Physics Teacher, v46 n9 p550-551 Dec 2008
A well-known classroom demonstration involves the rolling of hollow and solid objects down an incline. The fact that the objects roll at different rates can be used as a starting point in introducing students to rotational dynamics and rotational kinetic energy. In this paper we describe a simple quantitative version of the demonstration that is suitable for use as a laboratory experiment.
