### Differential Equation Of Linear Simple Harmonic Motion:-

Dear students in previous article we have learnt about the concept of linear simple harmonic motion. Then the linear simple harmonic motion is defined as, the linear periodic motion of a body, in which the restoring force or acceleration is always directed towards the mean position and is of magnitude proportional to the displacement from the mean position, is called linear SHM.

i.e. F α –x

F= -kx

Where K is constant called force constant. In magnitude,

k= F/x

Let’s obtain the differential equation for linear simple harmonic motion…..!

Consider a particle of mass m performing linear SHM with angular velocity ω. Let x be the displacement of particle from its mean position.

Then the restoring force acting on the particle is given as,

F= -Kx……..(1)

Also by Newton’s 2nd law of motion,

F = ma ……..(2)

From equations (1) and (2) we get,

ma = -kx……..(3)

Now the acceleration of the particle is given as,

### Let’s solve some MCQ’s….!
