Chapter 14 – Oscillations SHM

In mechanics and physics, simple harmonic motion is a special type of periodic motion where the restoring force on the moving object is directly proportional to the object’s displacement magnitude and acts towards the object’s equilibrium position. It results in an oscillation which, if uninhibited by friction or any other dissipation of energy, continues indefinitely. Simple harmonic motion can serve as a mathematical model for a variety of motions but is typified by the oscillation of a mass on a spring when it is subject to the linear elastic restoring force given by Hooke’s law. Simple harmonic motion can also be used to model molecular vibration as well.
