Question

name three important characteristics of SHM

Answer 1

These are Basic Conditions and characteristics for a body to exhibit SHM

A restoring force must act on the body.
Body must have acceleration in a direction opposite to the displacement and the acceleration must be directly proportional to displacement.
The system must have inertia (mass).
SHM is a type of oscillatory motion.
It is a particular case of preodic motion.
It can be represented by a simple sine or cosine function.

Answer 2

1) motion is periodic along a straight line .

2)force form acceleration is directed towards the mean position .

3)Force for acceleration is directly proportional to its displacement from mean position .

4)velocity of a particle is maximum at centre and minimum at extreme position .
