Definition
Rotational equilibrium occurs when there is no net torque acting on an object, resulting in a state where it remains at rest or rotates with constant angular velocity.

Center of Mass: The center of mass represents the average position of all particles making up an object. In rotational equilibrium, it remains stationary or moves with constant velocity.
Static Equilibrium: Static equilibrium refers to a state where an object is at rest and experiences no acceleration due to balanced forces acting on it.
Angular velocity measures how fast an object rotates around its axis. In rotational equilibrium, if there's no change in angular velocity over time, it indicates a state of equilibrium.
