The inverse-square law applies to gravitational and electrical forces. An inverse-square law tells you:That the force is inversely proportional to the square of the distance.That means that if the distance is increased by a factor "n", the force is decreased by a factor "n2".For example, if you increase the distance by a factor of 10, the force will decrease by a factor of 102 = 10 x 10 = 100.
Let's illustrate with an example. The square function takes a number as its input, and returns the square of a number. The opposite (inverse) function is the square root (input: any non-negative number; output: the square root). For example, the square of 3 is 9; the square root of 9 is 3. The idea, then, is that if you apply first a function, then its inverse, you get the original number back.
The slope of an inverse relationship
The opposite of another function - if you apply a function and then its inverse, you should get the original number back. For example, the inverse of squaring a positive number is taking the square root.
In an inverse relationship, one variable decreases while the other increases. As an equation, a basic inverse relationship looks like x = 1/y.
The inverse square law.
On a gravitational force vs distance graph, the relationship exhibited is an inverse square relationship. This means that as the distance between two objects increases, the gravitational force between them decreases proportionally to the square of the distance.
They are inverse functions of each other.

Square root is the inverse operation of a square.

demand line shows an inverse relationship
It is a relationship of direct proportion if and only if the graph is a straight line which passes through the origin. It is an inverse proportional relationship if the graph is a rectangular hyperbola. A typical example of an inverse proportions is the relationship between speed and the time taken for a journey.
The four kinds of proportionality in physics are direct proportionality, inverse proportionality, joint proportionality, and inverse square proportionality. Direct proportionality means that two quantities increase or decrease together. Inverse proportionality means that one quantity increases while the other decreases. Joint proportionality involves three or more quantities varying together. Inverse square proportionality refers to a relationship where one quantity is inversely proportional to the square of another quantity.
The inverse operation of taking the square root is to calculate the square.
