The circular frequency ω=√(k/m) of simple harmonic vibration is determined by the elastic coefficient K. The circular frequency, also called angular frequency, refers to the number of vibrations in 2π seconds. Simple harmonic vibration is the reciprocating motion of an object near its equilibrium position under the action of restoring force proportional to displacement.

App application

In modal extraction, the unit of natural frequency has two forms: rad/time and cycles/time. The former is the angular frequency (pi), and the latter is the frequency value we often use. The resonant angular frequency of LC oscillator circuit is. Where ω is the resonant angular frequency (rad/s), L is the inductance (h) and C is the capacitance (f).
