# Distance

The Simple English Wiktionary has a definition for: .distance |

**Distance** is how far one thing is from another thing. It is also a measure of the space between two things. It can be measured along any path. Thus, someone who goes around in a circle has traveled a distance, even though his position has not changed.

In geometry, the distance between two points *A* and *B* is sometimes written as .^{[1]} Pythagorean theorem is often used in the calculation of distance.^{[2]}^{[3]} Distance is a scalar, and thus is different from displacement. Displacement is a vector that measures distance with a straight line (and in only one path). Displacement is the shortest way to travel the distance.
