Question

Define phase and eposh of simple harmonic motion

Answer 1

Explanation:

Epoch is the initial phase of a particle and it remains constant all the time for a given motion.

Phase is the angular position of the particle on the circle which represents the given Simple Harmonic Motion. Phase would increase continuously with time going up by 2π radians for every oscillation.

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.
