JEE Main & Advanced Physics Simple Harmonic Motion Question Bank Energy of Simple Harmonic Motion

  • question_answer
    A body executes simple harmonic motion. The potential energy (P.E.), the kinetic energy (K.E.) and total energy (T.E.) are measured as a function of displacement x. Which of the following statements is true                             [AIEEE 2003]

    A)            P.E. is maximum when x = 0

    B)            K.E. is maximum when x = 0

    C)            T.E. is zero when x = 0

    D)            K.E. is maximum when x is maximum

    Correct Answer: B

    Solution :

               In S.H.M., at mean position i.e. at x = 0 kinetic energy will be maximum and pE will be minimum. Total energy is always constant.
