Question

What is simple harmonic motion?

Answer 1

a body is said to be in simple harmonic montion provided.
The motion should be periodic about a fixed point.
acceleration should be to and fro.
acceleration and displacement are always opposite in directions.
The acceleration should always be directed to work mean position.

Answer 2

$\huge \text{Simple\: Harmonic\: Motion }$

✍ It is an oscillatory (or vibratory) motion in which the acceleration of the particle is directly proportional to its displacement and acceleration is always directed towards its mean position.

✍ Examples ; The oscillations of a mass suspended to a spring.

✍ The oscillations of the bob of a simple pendulum.

$\Large \text{Characteristics\: Of\: Simple\: Harmonic\: Motion }$

✍ It is a periodic motion.

✍ It is a to and fro motion of a particle about its mean portion.

✍ The acceleration of the particle is directly proportional to its displacement.

✍ The acceleration of the particle is always directed towards its mean position .
