Every SHM is periodic motion, but every periodic motion need not be simple harmonic motion. Do you agree? Give an example to justify your statement.


#2

Yes, every periodic motion need not be SHM. e.g., the motion of the earth round the sun is a periodic motion, but not simple harmonic motion as the back and forth motion is not taking place.
