straight line that connects two points

Distance is how far one thing is from another thing. Distance is a measure of the space between two things.


  • 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.


Distance is different from displacement. Displacement is the difference between a starting point and a finishing point. It has both a distance and a direction.

Example of DisplacementEdit

  • Tom walks 6 kilometers north from his home. His displacement from home is 6 km north. Next he walks 10 km south. Now he has walked a distance of 16 km, but his displacement from home is 4 km south.
