inverse-square law

A relation between physical quantities of the form: x is proportional to 1/y2, where y is most often a distance, and x is often a force or flux.

An example of the inverse square law is the decrease of radiative flux with distance from a point source, as is often used to approximate radiation reaching the earth from the sun.
