In physics, angular frequency ω (also referred to by the terms angular speed, radial frequency, circular frequency, orbital frequency, radian frequency, and pulsatance) is a scalar measure of rotation rate. Angular frequency (or angular speed) is the magnitude of the vector quantity angular velocity. The term angular frequency vector is sometimes used as a synonym for the vector quantity angular velocity.
- k is the spring constant
- m is the mass of the object.
ω is referred to as the natural frequency (which can sometimes be denoted as ω0).
As the object oscillates, its acceleration can be calculated by
where x is displacement from an equilibrium position.
Using 'ordinary' revolutions-per-second frequency, this equation would be
