In mechanics and physics, simple harmonic motion is a special 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.

Simple harmonic motion can serve as a mathematical model for a variety of motions, such as the oscillation of a spring. In addition, other phenomena can be approximated by simple harmonic motion, including the motion of a simple pendulum as well as molecular vibration. 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. For simple harmonic motion to be an accurate model for a pendulum, the net force on the object at the end of the pendulum must be proportional to the displacement. This is a good approximation when the angle of the swing is small.

simple harmonic motion equations:
y = A * sin(ωt)
v = A * ω * cos(ωt)
a = - A * ω² * sin(ωt)
ω = 2πf

A is the amplitude of oscillations
ω is the angular frequency of oscillations in rad/s
f is the frequency
t is the time point when you measure the particle's displacement
y is the displacement
v is the velocity,
a is the acceleration
