Angular kinematics

Definition

Angular kinematics is the branch of mechanics that deals with the motion of objects in rotational motion without considering the forces that cause this motion. It focuses on parameters such as angular displacement, angular velocity, and angular acceleration, which describe how an object rotates around a fixed axis. Understanding these concepts is crucial for analyzing movements in sports and physical activities, as they provide insight into performance and technique optimization.
