How do we get the decay of energy equation for lightly damped oscillator?
A lightly damped harmonic oscillator loses energy at the rate of 1% per minute. The decrease in amplitude of the oscillator per minute will be closest to (a) 0.5% (b) 1% (c) 1.5% (d) 2% Ans.: (d) Solution: Decay of energy is governed by equation, E = E,e" Decay of amplitude is governed by equation, A = ae
