This equation proves that acceleration of the restoring force is directly proportional to the displacement. This scenario could either be vertical in which case gravity is involved as shown in Fig 1 or horizontal on a flat surface as shown in Fig 2.įor an oscillation particle like the one discussed above, let displacement = x, and its acceleration defined by the equation: Simple harmonic motion is any motion where a restoring force is applied that is proportional to the displacement and in the opposite direction of that displacement.Ī very common example of simple harmonic motion is a mass or particle attached to a spring, as more the particle is stretched or pulled, the more it experiences a force that pulls it back to the rest position which means it accelerates backwards.

Simple pendulum is also a simple harmonic motion as we showed that by resolving 2 rectangular components of weight of the bob, it is proved that acceleration of the restoring force is proportional to its displacement.

The period of oscillation in simple harmonic motion is given by the formula.

Simple harmonic motion is defined by the formula acceleration.

Simple harmonic motion is any motion where the acceleration of restoring force is directly proportional to its displacement.

Simple harmonic motion serves as a foundation for employing Fourier analysis techniques to analyse more complex periodic motion. 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).
