Rotational frequency

Rotational frequency refers to the number of complete rotations or cycles that an object makes in a given unit of time. It is typically expressed in hertz (Hz), where 1 Hz equals 1 rotation per second. In other words, if an object rotates once every second, its rotational frequency is 1 Hz. Rotational frequency can also be represented in terms of angular velocity, which is often measured in radians per second.
