An example of an inverse square relationship is the gravitational force between two masses. According to Newton's law of universal gravitation, the force decreases with the square of the distance between the two masses; if the distance between them doubles, the gravitational force becomes one-fourth as strong. This principle also applies to other phenomena, such as the intensity of light from a point source, where the brightness decreases with the square of the distance from the source.
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.
An example of an inverse relationship is the relationship between the price of a product and the quantity demanded by consumers. As the price of the product decreases, the quantity demanded typically increases, and vice versa. This relationship is often illustrated by the downward-sloping demand curve in economics. Another example can be found in physics, where the intensity of light decreases as the distance from the light source increases.
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.

demand line shows an inverse relationship
The inverse operation of squaring a number is finding the square root of that number. In mathematical terms, if you square a number x, the result is x^2. The inverse operation would be taking the square root of x^2, which gives you the original number x. For example, if you square 3 (3^2 = 9), the square root of 9 is 3.
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.
