Võrdetegur

Võrdetegur, also known as the proportionality factor or constant of proportionality, is a fundamental concept in mathematics and science. It represents the constant ratio between two quantities that are directly proportional to each other. In simpler terms, if two variables, say *x* and *y*, are directly proportional, it means that as *x* changes, *y* changes by the same factor. This relationship can be expressed mathematically as y = kx, where *k* is the võrdetegur.

The võrdetegur quantifies the strength and direction of this proportional relationship. A positive võrdetegur indicates that as one variable increases, the other also increases, and vice versa. A negative võrdetegur signifies an inverse relationship, where an increase in one variable leads to a decrease in the other. The magnitude of the võrdetegur determines how quickly one variable changes in response to changes in the other. A larger absolute value of *k* implies a more significant change.

This concept is widely applied in various fields. In physics, it appears in Hooke's Law (force is proportional to displacement, with the spring constant as the võrdetegur) and Ohm's Law (voltage is proportional to current, with resistance as the võrdetegur). In economics, it can describe the relationship between supply and demand. In everyday life, it's seen in simple conversions, like the relationship between feet and inches, where the võrdetegur is 12. Understanding the võrdetegur allows for accurate prediction and analysis of how quantities relate and change together.
