Simple harmonic motion is typified by the motion of a mass on a spring when it is subject to the linear elastic restoring force given by #Hooke's_Law. The motion is #sinusoidal in time and demonstrates a single resonant frequency.
#SHM is a type of Periodic and Oscillatory Motion.
There is always a restoring force acting on an object in SHM, which always acts in the opposite direction to the displacement of the object from the mean position.
The amplitude in the SHM remains constant throughout the motion of the object.
The acceleration of the object is directly proportional to the #displacement of the object from its mean position.
The velocity of the object is maximum at the equilibrium position.
The total energy in SHM remains conserved, as there is always a conversion of kinetic and potential energy happening throughout the motion.
Examples of Simple Harmonic Motion(SHM)
There are a lot of examples of Simple Harmonic Motion around us, we just need to see them from the perspective of SHM. From swings in the park to the motion of the cantilever, all are examples of SHM. The following illustration shows different examples of Simple Harmonic Motion.
