Simple Harmonic Motion and its Characteristics

Simple Harmonic Motion: 
The to and fro motion of a particle about a mean position on a fixed path such that the acceleration of the particle is always directed to the mean position and is directly proportional to the displacement of the particle from its mean position is called Simple harmonic motion.

Characteristics of SHM:
1. A constant time period (T) (or) a constant frequency υ = 1/T
2. An amplitude (A)
3. A constant mechanical energy which is the sum of potential energy and Kinetic energy at every point in the path of oscillation.
