Can a motion be oscillatory but not simple harmonic ?
Answers
yes, a vibrating phone doesn't perform shm
✍ The term of of oscillation first came under scientific scrutiny was that a taur string when plucked. Even our ancients knew that strings produced musical sounds when plucked by passing on their own oscillatory motions to the air itself.
✍ The first to study such oscillations was the ancient Greek mathematician and philosopher Pythagoras of samos (600 BC). He was interested only in relationship of the oscillations to music. As a result, vibratory motion is frequently called harmonic motion. Harmonic motion is a term associated with music.
✍ Most of the vibratory motion sir very complicated to analyse oscillations of a taut a string is the simplest and therefore its motion came to be known as Simple Harmonic Motion (SHM).
