![]() The motion is sinusoidal in time and has a single resonance frequency. Note: Simple harmonic motion can be used to mimic a number of motions, but it is best exemplified by the oscillation of a mass on a spring when it is subjected to Hooke's law's linear elastic restoring force. The eardrum vibrates back and forth in response to sound waves entering our ears. Hearing: Hearing is impossible to achieve without simple harmonic motion. The bungee cord's elasticity causes the jumper to oscillate up and down, causing SHM.Ĭradle: The back and forth movement of the cradle is created by a single push and maintained by the SHM principle, putting the baby to sleep. Pendulum: Simple harmonic motion is demonstrated by a pendulum swaying back and forth from its mean position.īungee Jumping: Simple harmonic motion is demonstrated by bungee jumping. The simple harmonic motion is the swing's back and forth, repeating movements against the restoring force. ![]() Swing: Swings in parks are a good illustration of simple harmonic motion. ![]() ![]() This motion is used to represent a variety of real-life scenarios in our daily lives. Hint:Simple harmonic motion is a type of periodic motion in mechanics and physics in which the restoring force on a moving object is directly proportional to the magnitude of the object's displacement and acts towards the object's equilibrium position.Ī simple harmonic motion occurs when an object moves to and fro or back and forth along the same line (SHM). ![]()
