## What is simple harmonic motion in physics?

## What are the characteristics of harmonic superposition?

- Any oscillatory
**motion**which is not**simple Harmonic**can be expressed as a superposition of several**harmonic**motions of different frequencies. A**motion**repeats itself after an equal interval of time. For example, uniform circular**motion**. There is no equilibrium position. There is no restoring force.

## What is the direction of restoring force in simple harmonic motion?

- The direction of this restoring force is always towards the mean position. The acceleration of a particle executing simple harmonic motion is given by, a (t) = -ω 2 x (t). Here, ω is the angular velocity of the particle.

## What is simple harmonic periodic periodic and oscillation motion?

**Simple Harmonic**, Periodic and Oscillation**Motion**.**Simple harmonic motion**can be described as an oscillatory**motion**in which the acceleration of the particle at any position is directly proportional to the displacement from the mean position. It is a special case of oscillatory**motion**.
