is every oscillatory motion simple harmonic ? give examples
Answers
Therefore, every oscillatory motion is periodic but all periodic motions are not oscillatory. ... Simple harmonic motion is the simplest form of oscillatory motion. This motion takes place when the restoring force acting on the body is directly proportional to its displacement from its equilibrium position.
Answer:
Definition
(SHM) is defined Linear simple harmonic as the linear periodic motion motion ofa body, in which the force (or acceleration) is always directed towards the mean position and its magnitude is proportional to the displacement from the mean position.
OR
A particle is said to execute linear SHM if the particle undergoes oscillations about a point of stable equilibrium, subject to a linear restoring force always directed towards that point and whose magnitude is proportional to the magnitude of the displacement of the particle from that point.
Examples : The vibrations of the tines (prongs) of a tuning fork, the oscillations of the needle of a
sewing machine.
