When an object is traveling in a circle, it requires a force to keep it turning since the velocity vector changes direction. That force depends on the following parameters and variables: the objects's mass m, the distance the object is from the center of the circle R, and the angular velocity of the object, v (the angular velocity has dimension of 1/Time as noted below).
A force has dimensions, [F]=ML/T2. If our parameters and variables have the following dimensions, [m]=M, [R]=L, and [v]=1/T, propose a possible equation for F that expresses the way it could depend on m, R, and v.
