Simple harmonic motion is a type of periodic motion or oscillation motion where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement.
EXAMPLES:

• simple pendulum.
• mass spring system.
• a steel ruler clamped to a bench oscillates when its free end is displaced sideways.
• a steel ball rolling in a curved dish.
• a swing.
