Page 1 of 9 Physics Notes Ch 7 and 8 - Circular Motion, Equilibrium, and Torque I. Rotational and Circular Motion • Rotational motion refers to the motion of a body or system that spins about an axis. about the axis of rotation. Therefore when the net torque is zero, the object remains in rotational equilibrium. This implies that either the object does not rotate (rotational static equilibrium) or that it rotates with a constant angular velocity (dynamic equilibrium).

Mechanical equilibrium is a subset of static equilibrium. Dynamic equilibrium is where a body is accelerating and moving at constant velocity at the same time. An example of this is a ball that is spinning while not moving linearly. Every spinning object experiences a centripetal acceleration. In the example the object is spinning but not experiencing any translational motion. 4 Rotational equilibrium If a structure is in equilibrium, the torque caused by one force must be bal-anced by the turning effect of one or more other forces.
