Rotational Equations
In the same way, we can derive nice formulas for the kinetic energy and (angular) momentum due to the spinning of an object; basically we replace F with t, m with I, v with w, a with a and p with L (where L is the angular momentum):
KE = (1/2)mv2 KErotation = (1/2)Iw2
S F = Dp/Dt S t = DL/Dt .
