# Characteristics of simple harmonic motion

## What are the three characteristics of simple harmonic motion?

1-

**A restoring force must act on the body**. 2- Body must have acceleration in a direction opposite to the displacement and the acceleration must be directly proportional to displacement. 3- The system must have inertia (mass).## What is the characteristic equation of simple harmonic motion?

**Ï‰=âˆškm**. The angular frequency depends only on the force constant and the mass, and not the amplitude. The angular frequency is defined as Ï‰=2Ï€T, which yields an equation for the period of the motion: T=2Ï€âˆšmk.

## Why is it called simple harmonic motion?

The motion is called harmonic because

**musical instruments make such vibrations that in turn cause corresponding sound waves in air**.## What is meant by simple harmonic motion?

Simple harmonic motion is defined as

**a periodic motion of a point along a straight line, such that its acceleration is always towards a fixed point in that line and is proportional to its distance from that point**. From: Newnes Engineering and Physical Science Pocket Book, 1993.## What are the types of simple harmonic motion?

SHM or Simple Harmonic Motion can be classified into two types:

**Linear SHM**.**Angular SHM**.## What is the frequency of SHM?

The frequency of SHM is

**100 Hz**.## What are some examples of simple harmonic motion?

**The pendulum oscillating back and forth from the mean position**is an example of simple harmonic motion. Bungee Jumping is an example of simple harmonic motion. The jumper oscillating up and down is undergoing SHM due to the elasticity of the bungee cord.

## What are the two basic characteristics of a simple harmonic motion class 11?

1.

**The restoring force (or acceleration) acting on the particle is always proportional to the displacement of the particle from the equilibrium position**. 2. The force (or acceleration) is always directed towards the equilibrium position.## What are the characteristics of oscillatory motion?

**Time period (or) Frequency**.

**Phase**.

**Amplitude**.

**Velocity**.

## What is simple harmonic motion write its characteristics and give its graphical representation?

**The graphical representation of displacement, velocity and acceleration of the particle vibrating in SHM is given below**. (i) The displacement of the particle is given by the expression y = A sin Ï‰t. When y = Â± A, the displacement of the particle is maximum.

## What is simple harmonic motion class 11th?

If the restoring force/torque acting on the body in oscillatory motion is directly proportional to the displacement of the body and is always directed towards the equilibrium position, then the motion is called Simple Harmonic Motion (SHM).
