Q.1 What is simple-harmonic motion? What are the necessary conditions for a body to execute simple harmonic motion?
Ans. Simple Harmonic Motion:
The special kind of vibratory motion of a body, whose acceleration is directly proportional to its displacement from mean – equilibrium position, is called the simple harmonic motion.
Conditions for SHM:
- Acceleration is directly proportional to its displacement.
- Acceleration is directed towards the mean position.
