Centripetal acceleration: This term refers to the acceleration experienced by an object moving in a circular path. It always points towards the center of the circle.
Moment of inertia: Moment of inertia is a measure of an object's resistance to changes in its rotational motion. It depends on both the mass distribution and shape of the object.
Torque is the rotational equivalent of force. It causes objects to rotate around an axis and depends on both the magnitude and direction of applied force.
