Simple Harmonic Motion is a special type of periodic motion, where the restoring force (F) is directly proportional to the displacement(x) and acts in the opposite direction of displacement. For example, the periodic motion of a pendulum.
All oscillatory motions are periodic, but not all periodic motions are oscillatory in nature. The vibrating body must possess to and fro motion about its mean position for oscillatory motion.
