Rigid body centripetal acc

  1. Dec 12, 2006 #1
    Does a rotating rigid disk, for example, feel centripetal acceleration at each point of its body?

    or more general: Is centripetal acceleration only for non-rigid bodies? (ball on a string, ex)?

    yes. or rather, it "feels" the centrifugal force..
