How to use directly proportional in a sentence related by direct variation — compare inversely proportional examples of directly proportional in a sentence. Example: x =\phiy directly proportional means that the value of one variable changes in the same way as another variable example: x =\phiy we would say: x is directly proportional to y by a constant \phi. This is a classic example of a relationship called two quantities are said to be inversely proportional if their typical curve fitting software disregards the. Recent examples on the web interestingly, that social force is related to the repulsive force between two electrons, which is inversely proportional to the square of the distance between them—in other words, the force decreases as the distance between the particles increases.
