Angular motion is described by angular momentum, which, like linear momentum, is conserved in the absence of external torques. We define angular velocity, using the right-hand rule for its direction, and establish relationships among angular displacement, velocity, and acceleration. This framework enables analysis of rotating systems and their dynamics.
