Angular Frequency
Reference from the original Physics I textbook.
- Angular Frequency
Angular frequency is the rate of change of phase in a periodic oscillation: ω = 2πf. Its unit is rad/s; it need not describe an object physically spinning.
One complete cycle in a sine graph occurs in every increments but the time may vary, so for sine graphs it measures the rate of change of a function at a given time, and position, .

Angular frequency
Angular frequency measures how rapidly the phase of a sinusoidal oscillation advances. It equals two pi times the ordinary frequency and is measured in radians per second. For example, two oscillators at the same ordinary frequency also have the same angular frequency even if their amplitudes differ.
