Ice skating and conservation of conservation of rotational momentum

Ice skating from the Olympics (6.7 MB! MPEG file). “Right click” and “Save as…” the file to save it to your computer. Then open it with your favorite video player. QuickTime^® allows you to step forward one frame at a time using the right arrow key, which makes it easy to measure the time of each rotation.

I hope to be adding more tips on how to use this in the classroom soon.
