Angular frequency is typically denoted by the Greek letter omega. Typical units: radians/second. omega = 2*PI*f, where f denotes frequency

frequency multiplied by the number 2Ï€. The "angular" bit is essentially a red herring, but is related to the fact that an angle of 2Ï€ radians is one revolution. Usual symbol: (Greek lower-case omega). The SI unit is the reciprocal second, symbol s-1, but some folks, confused by the "angular" part of the name, use radian per second (rad.s-1).

frequency of oscillation or rotation (measured, e.g. in radians/second) commonly designated by omega: omega = 2·pi·nu, where nu is the frequency (e.g. in Hertz [Hz]).

For any oscillation, the number of vibrations per unit time, multiplied by 2. Also known as angular velocity and radian frequency.

The motion of a body or a point moving circularly, referred to as the circular frequency O which is the frequency in cycles per second (cps) multiplied by the term (2) and expressed in radians per second (2pf).

A frequency, , defined as the number of revolutions a rigid body makes in a given time interval. It is a scalar quantity commonly denoted in units of Hertz (Hz) or sâ€“1.

In physics (specifically mechanics and electrical engineering), angular frequency Ï‰ (also referred to by the terms angular speed, radial frequency, and radian frequency) is a scalar measure of rotation rate. Angular frequency is the magnitude of the vector quantity angular velocity. The term angular frequency vector \vec{\omega} is sometimes used as a synonym for the vector quantity angular velocity .
