WebThe formula for rotational kinetic energy is 1/2 times the moment of inertia or the rotational inertia times the angular speed squared. Which makes sense because the formula for regular kinetic energy is 1/2 times the regular inertia, the mass times the regular speed squared. Again, if an object is rotating, it's got rotational kinetic energy. WebAnswer: MI of a rod rotating about its end gives you the MI of each spoke. (ML^2/3) Multiply this by the no. of spokes.
