    Question

    Which of the following is not a characteristic of simple

    harmonic motion (SHM)?
    A Restoring force is proportional to displacement Correct Answer Incorrect Answer
    B Acceleration is constant Correct Answer Incorrect Answer
    C Motion is periodic Correct Answer Incorrect Answer
    D Displacement is sinusoidal Correct Answer Incorrect Answer

    Solution

    In SHM, the restoring force is F = −kx, which makes acceleration proportional to and opposite of displacement. Hence, acceleration changes with time and is not constant. Motion is periodic and displacement follows a sine or cosine function. Thus, option B is not a characteristic of SHM.
