In physics and systems theory, the superposition principle, also known as superposition property, states that, for all linear systems, the net response at a given place and time caused by two or more stimuli is the sum of the responses which would have been caused by each stimulus individually.ecause physical systems are generally only approximately linear, the superposition principle is only an approximation of the true physical behaviour. The superposition principle applies to any linear system, including algebraic equations, linear differential equations, and systems of equations of those forms.
