Angular velocity is a measure of the rate at which an object rotates or revolves around a specific axis. It quantifies how quickly an angle changes as a function of time. Angular velocity is typically denoted by the symbol \(\omega\) (omega) and is expressed in radians per second (rad/s), although it can also be represented in degrees per second or other units depending on the context.
