Energy in SHM

If the amplitude of linear S.H.M. is decreased then

Show answer and solution

Answer: (d)

  1. Period T=2πm/kT = 2\pi\sqrt{m/k} does not depend on amplitude.
  2. E=12kA2E = \dfrac{1}{2}kA^2, so a smaller AA gives smaller energy.
  3. So the answer is (d): period unchanged, total energy decreases.
