Definition
Rotational acceleration refers to the rate at which an object's angular velocity changes over time. It is a measure of how quickly an object can speed up or slow down its rotational motion.
Moment of inertia measures an object's resistance to changes in its rotational motion. It depends on both the mass distribution and shape of the object.
