What is the underdamped frequency of an oscillation?

  1. Jun 10, 2013 #1
    A mass is attached to a spring in underdamped oscillation, the damped frequency is ω^2=( ω1 )^2 -(∂/2m)^2
    where ω is the damped angular frequency
    ω1 is the natural angular frequency
    ∂ frictional coefficient
    m is the mass attached to the spring

    is the damped angular frequency is constant throughout the oscillations ( I mean the angular oscillation is constant until the oscillation stop)
    I think the oscillation should not oscillate with constant angular damped frequency. but the formula of damped oscillation is not varies with time so is that constant??

    thank you.
