rotational inertia
Rotational inertia, also known as moment of inertia, refers to the resistance an object tends to exhibit to changes in its rotational motion. It depends on the object's mass distribution and how it is distributed around its axis of rotation. In simpler terms, it is the property that determines how difficult it is to start or stop an object's rotation or change its rotation speed.
