Question

Which of the following examples represent (nearly) simple harmonic motion and which represent periodic but not simple harmonic motion? Motion of a ball bearing inside a smooth curved bowl, when released from a point slightly above the lower most point.

✓

Answer

It is simple harmonic motion because the ball moves to and fro about the lowermost point of the bowl when released. Also, the ball comes back to its initial position in the same period of time, again and again.
