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

  1. Oct 26, 2008 #1
    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.

    Hi Chronothread! :smile:

    (you didn't say :rolleyes: , but i assume the wheel is rolling, along a flat surface :wink:)

    Use centripetal acceleration …

    Hint: what is the angular velocity of the wheel?
