Qn2 The amplitude of a lightly damped osciallator decreases by 3% during each cycle of oscillation. What fraction of the energy is lost in each cycle? Okay..i couldnt find anything about energy in the damped oscillation is my textbook.. but in SHM sections. it showed that Energy of the SHM system = (1/2)kAsquare where A is the amplitude and k is the coefficient for the spring.. but for lightly damped osciallator...the Energy of the SHM will change for every cycle..in this case, it will drop by 3%... i know that the period for every cycle is the same but only the amplitude will change. here is my guess... Energy of the SHM system = (1/2)kAsquare -----------> first cycle Energy of the SHM system = (1/2)k(A*0.97)square -----------> second cycle Energy lost = (1/2)kAsquare - (1/2)k(A*0.97)square ----------> difference Fraction of energy lost = difference/(1/2)kAsquare am i right here?...i am a feeling i am wrong..but dun know how to aprroach this..
