Product Description

The Eisco Labs Disk and Ring Race Demonstration Set includes 2 wooden disks and 1 metal ring. Racing combinations of the three objects down an incline demonstrates how rotational inertia depends on mass distribution relative to the axis of rotation. The object with greater rotational inertia rolls more slowly, arriving at the bottom later. This classic experiment reinforces concepts in rotational dynamics. Suitable for physics classrooms.
