Dear student,

The centrifugal force on a particle that is constrained to rotate in a circular path is given by

      F_c = mrw²                                                                                                       

where F_c is the centrifugal force acting on the particle to maintain it in the circular path, r is the radius of the path, m is the mass of the particle, and w(omega) is the angular velocity of the particle.

Or, since w = v/r, where v is the tangential velocity of the particle

      F_c = (mv²)/r
