What is meant by "angular velocity"?

Angular velocity refers to the rate at which an object rotates around a specific axis, indicating how quickly it is changing its angle of rotation over a given period. This concept is crucial in biomechanics as it helps quantify the rotational dynamics of limbs and joints during movement. In mathematical terms, angular velocity is defined as the change in angular position (or angular displacement) relative to the time taken for that change. This means it provides insight into how fast an object is spinning or turning, measured in radians per second or degrees per second.

By understanding angular velocity, biomechanics professionals can analyze movements such as a gymnast performing a routine or an athlete executing a throw, allowing them to assess efficiency and performance in rotational sports.
