There is no real resistance to a change of angular momentum, just as there is no actual resistance to a change of linear momentum. If an object feels a net force for a length of time, the linear momentum changes by the product of the net force and the time. If an object is twisted with a net torque for a certain time, angular momentum changes by the product of the torque and the time. You are looking for resistance to angular acceleration. The torque is how hard the object is being twisted, how hard you are trying to change its rotational motion.
Angular acceleration is how fast the angular velocity is changing.
Moment of inertia is the object's resistance to rotational change. With rotational motion, it is moment of inertia. It takes more space to explain than is reasonable for this letter. Argonne National Laboratory, Division of Educational Programs, Harold Myron, Ph.D., Division Director.
