## What is the graphical representation of SHM?

This is a standard equation of an ellipse. The graph between velocity and displacement is an ellipse, it can be represented as. The acceleration of the particle is given by the equation. a = – Aω2sin(ωt) a = – ω2y.

## How do you show something in SHM?

Proving Simple Harmonic Motion

1. A particle is attached to an extensible string (the tension in string, T=λxl) and the particle is pulled so that the string is extended and released from rest. As in this diagram:
2. SHM is proved by a=−w2x.
3. R(−>)=−T=−λxl.
4. R(−>)=m(−a)
5. m(−a)=−λxl.
6. ma=λxl.
7. a=λmlx.

What do you understand by SHM explain its geometrical interpretation?

Simple Harmonic Motion or SHM is defined as a motion in which the restoring force is directly proportional to the displacement of the body from its mean position. The direction of this restoring force is always towards the mean position.

What is differential equation of SHM?

dtd2x=−w2x.

### What is the nature of graph between displacement and velocity of SHM?

Statement 1: The graph between velocity and displacement for a harmonic oscillator is an ellipse.

### How do you find the period of a harmonic motion graph?

ω = k m . The angular frequency depends only on the force constant and the mass, and not the amplitude. The angular frequency is defined as ω = 2 π / T , ω = 2 π / T , which yields an equation for the period of the motion: T = 2 π m k .

How do you find the amplitude of oscillation on a graph?

In most cases, the oscillating variable is displacement. When we plot the graph of the sinusoidal function, with an oscillation variable displacement as the vertical axis and the time as the horizontal axis, the vertical distance between the mean value to the extrema of the curve illustrates the oscillation amplitude.

How do you derive the equation of SHM?

The velocity of the mass on a spring, oscillating in SHM, can be found by taking the derivative of the position equation: v(t)=dxdt=ddt(Acos(ωt+ϕ))=−Aωsin(ωt+φ)=−vmaxsin(ωt+ϕ). Because the sine function oscillates between –1 and +1, the maximum velocity is the amplitude times the angular frequency, vmax = Aω.

## What is condition of SHM?

Condition for SHM. In order for an object to display simple harmonic motion, the resultant force acting on the object must be directly proportional to its displacement from its equilibrium point, and must act towards the equilibrium point – it must act in the opposite direction to the displacement.
