Rotational kinematics refers to the study of motion for objects that are rotating or undergoing rotational motion. It involves concepts such as angular displacement, angular velocity, and angular acceleration.
Angular displacement measures the change in angle or position of an object undergoing rotation. It is usually measured in radians.
Angular velocity refers to how quickly an object rotates around a fixed axis. It is measured in radians per second.
Angular acceleration represents how quickly an object's angular velocity changes over time. It is measured in radians per second squared.
