AP Physics C: Rotational Kinematics Review (Mechanics)

The video tutorial covers key concepts in rotational kinematics, including angular velocity and acceleration, arc length, and tangential velocity and acceleration. It explains uniform and non-uniform circular motion, centripetal force, and the derivation of related equations. The tutorial also discusses the application of these concepts in physics, particularly in the context of the AP Physics C Mechanics curriculum.
