It's actually much less work than trying to get Megapov's physics 
simulation do the job for you.

I guess the formula will boil down to something like:

     RelativeLoss = const[0..1)
     AbsoluteLoss = const[0..1)
     Frequency = const
     MaxAmplitude = const

     Energy[t] = max(0, (1-RelativeLoss)^t - AbsoluteLoss*t)
     Amplitude[t] = Energy[t] * MaxAmplitude * sin(t*Frequency)
