    Okay, so we know that the total energy of an oscillator is proportional to amplitude squared

    Let's say the amplitude of this oscillator decreases by 5% in one cycle. Does this mean that the energy decreases by sqrt(5)% in one cycle?

    if the amplitude is 0.95 of what it was then the energy will be (0.95)^2 of what it was, i.e. 0.9025 times or 90.25%
