Center of mass: The center of mass is the average position of all the parts of a system, weighted according to their masses. It behaves as if all the mass were concentrated at that point.
Rotational motion: Rotational motion refers to the movement of an object around an axis, resulting in changes in its orientation or angular position.
Translational motion: Translational motion is the straight-line movement of an object from one point to another without any rotation.
