===Meaning===
[[Angular Frequency|Angular frequency]] is the rate of change of [[Angular Displacement|angular displacement]] with respect to [[time]], often used in oscillatory systems.
===About Angular Frequency===
*[[Angular Frequency|Angular frequency]] is given by the symbol '[[Angular FreuquencyFrequency|ω]]'(a lower case Omega in the Greek Alphabet).
*[[Measure]]d in [[radian]]s per [[second]] (rad/s).
*Relates to the [[frequency]] of [[oscillation]] (f) by the formula ω = 2πf.
*Indicates how quickly an [[object]] moves through its circular path.
*[[Angular Frequency|Angular frequency]] is used to describe the motion of [[object]]s in periodic motion, such as [[pendulum]]s and springs.
*[[Angular Frequency|Angular frequency]] is an important concept in the analysis of [[wave]] motion and [[Simple Harmonic Motion|simple harmonic motion (SHM)]].
*[[Angular Frequency|Angular frequency]] is also used in [[Alternating Current|alternating current]] circuits to describe the oscillations of [[volt]]age and [[current]].
