# Why is the acceleration on a point on a wheel what it is.

1. Oct 26, 2008

Hello. My brain doesn't seem to be working at the moment. If a wheel's center is traveling at V0, why is the acceleration of a point on the edge of the wheel equal to V02/r where r is the radius of the wheel? Thanks for your time.

Edit:

Oops should have have put a question mark in the title... meh.
