Answer Hint:We are asked to find out how much part of total energy is potential energy and kinetic energy. First recall the formulas for total energy and potential energy in S.H.M or simple harmonic motion, use those to find out the part of total energy which is potential energy. Then use conservation of energy to find out the part for kinetic energy. Complete step by step answer: Therefore, kinetic energy is \[\dfrac{8}{9}\] of total energy and potential energy is \[\dfrac{1}{9}\] of total energy. Note:S.H.M or Simple harmonic motion is a type of oscillatory motion and also periodic. In case of S.H.M the restoring force is directly proportional to the displacement from the mean position. One important point you should remember is that all S.H.M are oscillatory motions but all oscillatory motions may not be S.H.M. |
