Product Details

Quickly demonstrate angular momentum—with a twist! Stand on a rotating platform holding the dumbbells straight out. After a slow rotation is applied, pull in the dumbbells as close to your body as possible. Your students will be astonished with how fast you spin—just like a figure skater at the Olympics. This simple demonstration effectively illustrates the concepts of angular momentum, and it is safe for students to have their own hands-on experience. A reproducible student worksheet, detailed background information and complete demonstration instructions are provided.

Concepts: Conservation of angular momentum.
Time Required: 15 minutes
Note: Rotational turntable is required and available separately.
