http://www3.eng.cam.ac.uk/~hemh1/gyroscopes/momentinertia.html WebThe moment of inertia, otherwise known as the angular mass or rotational inertia, of a rigid body is a tensor that determines the torque needed for a desired angular acceleration about a rotational axis. It depends on the body's mass distribution and the axis chosen, with larger moments requiring more torque to change the body's rotation. bleach vol 39
