Question

justify why every simple harmonic motion is a periodic motion whereas the converse need not be true in tidal waves and waves on pond surface

please justify it with some more points please give a clear answer bcoz i didnt get it dont give one word answers.​

Answer 1

The motion of the hands of a clock or the motion of the planets and satellites are periodic in nature. But as these motions do not satisfy the above conditions, they cannot be called simple harmonic. So it can be said that all simple harmonic motions are periodic but all periodic motions are not simple harmonic
