Simple harmonic motion is the motion of an oscillating body, where acceleration is  ∝ - x∝ - x²∝ v²∝ x. For a body undergoing simple harmonic motion, there is always a force which  acts against gravityslows the oscillationreturns the body to its original positionpushes the body away from the equilibrium point.
For simple harmonic motion, velocity is the rate of change of the  displacementforceamplitudeacceleration.
Simple harmonic systems which oscillate with no external forces acting are said to undergo  freepotentialdampedforced vibrations. A periodic force which causes simple harmonic motion is called the  freerestoringdrivingresonant force. When this force matches the system's natural frequency,  random motiondrivingharmonyresonance occurs, which greatly increases the amplitude of oscillations.
For an isolated system in simple harmonic motion,  kinetic energy ÷ potential energypotential energy ÷ kinetic energypotential energy - kinetic energykinetic energy + potential energy is constant. Any force which dissipates energy in a simple harmonic system  harmonisesholdsresonatesdamps the system.
