Distance
length of straight line that connects two points in a measurable space or in an observable physical space
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.
