From Simple English Wikipedia, the free encyclopedia

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.

Examples[change | change source]

  • One ball is 5 feet from another ball. The distance between the two balls is 5 feet.
  • John walks at a speed of 6 kilometres per hour for one hour. John walks a distance of 6 kilometres.
  • A circle is a curved line. Each point on the circle is the same distance from the centre of the circle.
