Homework Help: Formula for the velocity of the centripetal force

  1. Mar 7, 2009 #1
    Hi, can anyone please tell me the fomular for the velocity of a centripital force with the radius of 100 cm, with one revolution revolting in 0.98 seconds?

    Re: velocity

    Here are the formulas you will need to solve the problem:
    v = rw
    w = 2pi/T

    By the way, the "velocity of a centripetal force" does not have much meaning. Force is a vector; it doesn't have velocity. You might as well have asked what the mass of the force was, or the radius of the force. I think you meant to say that you are trying to find the tangential velocity of an object undergoing circular motion due to a centripetal force.

    Thanks for you're help, anyway i have another question. What is the formula for centripital force?, our physics teacher gave us a practical to do but he forgot to give us a note on centripital force.

    It's F = (mv^2)/r, directed radially inward.
