Rotational Motion

Definition

Rotational motion refers to the movement of an object around a fixed point or axis, where every point in the object moves in a circular path. This type of motion is characterized by parameters such as angular displacement, angular velocity, and angular acceleration. In robotics and unmanned aerial vehicles, understanding rotational motion is crucial for controlling movements, ensuring stability, and calibrating systems to achieve desired orientations and trajectories.
