Difference between Periodic, Oscillation, and Simple Harmonic Motion
There are some differences between Periodic motion, Oscillatory Motion, and Simple Harmonic Motion, which are listed as follows:
| Periodic Motion | Oscillatory Motion | Simple Harmonic Motion |
|---|---|---|
| The motion of an object is said to be periodic if it moves in such a way that it repeats its path at regular intervals of time. | The to-and-fro motion of an object from its mean position is defined as oscillatory motion. | Simple Harmonic Motion is the motion of an object, around a mean position in which the acceleration of the particle is directly proportional to the displacement of the particle. |
| Some Examples of Periodic motion include the motion of hands in a clock, the movement of the Earth around the Sun, and a simple pendulum. | Examples of oscillatory motion include a simple pendulum, a vibrating tuning fork, AC current, waves such as sound waves, ocean waves, or light waves, etc. | Examples of SHM are the motion of a spring system i.e., a mass attached to the end of a spring, swings, and the motion of a cantilever. |
| Periodic motion is not always harmonic. | Oscillatory Motion is not always periodic, | SHM is an example of Periodic and Oscillatory motion. |

Simple Harmonic Motion
Simple Harmonic Motion is a fundament concept in the study of motion, especially oscillatory motion; which helps us understand many physical phenomena around like how strings produce pleasing sounds in a musical instrument such as the sitar, guitar, violin, etc., and also, how vibrations in the membrane in drums and diaphragms in telephone and speaker system creates the precise sound. Understanding Simple Harmonic Motion is key to understanding these phenomena.
In this article, we will grasp the concept of Simple Harmonic Motion (SHM), its examples in real life, the equation, and how it is different from periodic motion.
