Explain Superposition principle and their illustrations

Explain Superposition principle and their illustrations?

Superposition principle:

The common idea that, whenever a number of influences are performing on a system, the net influence on that system is just the sum of the individual influences; i.e., the influences governed by the superposition principle summed linearly. Some particular illustrations are:

Superposition principle of forces: The total force on a body is equivalent to the sum of the forces impressed on it.

Superposition principle of states: The resulting quantum mechanical wave-function due to two or more than two individual wave-functions is the total sum of the individual wave-functions.

Superposition principle of waves: The resulting wave function due to two or more individual wave functions is the addition of the individual wave functions.
