## Angular Frequency

By Boyang Zhao

Angular frequency, also called angular speed, is the magnitude of the angular velocity. Angular frequency is related period with the following formula,

$\omega=\frac{2\pi}{T}$

Angular frequency can also be expressed in terms of frequency, as shown below,

$\omega=2\pi f$

The angular frequency of the vibration of an object of mass m on a spring (with spring constant k) is given by the following formula,

$\omega=\sqrt{\frac{k}{m}}$

Note: In the above formula, angular frequency must be expressed in terms of radians per second.
