Question

Define phase of a simple harmonic motion.

Answer 1

simple harmonic motion means that knowing the constants of a SHMand the phase would be enough to completely define it. When adding two or more simple harmonic motions, phase is a very important term. Imagine two SHMs of equal amplitude and frequency.

Answer 2

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.
