Angular Frequency

An Angular Frequency is a measure of the rate of angular motion or the phase of a sinusoidal motion.

• AKA: Angular Speed, Radial Frequency, Circular Frequency, Orbital Frequency, Radian Frequency, Pulsatance.
• Context:
  • It can be expressed as

[math]\displaystyle{ \omega=\frac{2\pi}{T} }[/math]

where [math]\displaystyle{ T }[/math] is period of the angular motion or the sinusoidal motion

• Example(s):
  • Simple Harmonic Oscillator.
• Counter-Example(s):
  • Period.
• See: Harmonic Oscillator.
