# Velocity Experiment Using a Thin-Walled Cylinder

A report on an experiment designed to demonstrate that the radius r of a thin-walled, rigid-body cylinder, when neglecting friction, has no effect upon the velocity of the center of mass vcm of the cylinder down an inclined plane of constant angle q.

“This is accomplished by showing that vcm of the cylinder is a function of gravity g down an inclined plane and the height h of the inclined plane, unaffected by the radius of the cylinder as given in the equation

vcm = (gh)1/2

The lab is an original comprehensive work with a full theoretical background of derived equations, and tables and graphs displaying all pertinent experimental data. ”
