Quizplus · Accepted Answer

The measure of how hard it is to rotate something with respect to its center of rotation is called mass moment of inertia. Option A, mass, is a measure of the amount of matter in an object. Option B, momentum, is a measure of an object's motion and is calculated as the product of an object's mass and its velocity. Option C, torque, is a measure of the amount of twisting force applied to an object and is related to rotational motion but not specifically to the measure of how hard it is to rotate an object.
