The distance between a starting point and an ending point is called displacement.

Here's why:

* Distance is the total length of the path traveled, regardless of direction.

* Displacement is the straight-line distance between the starting point and the ending point, taking direction into account.

For example:

* If you walk 5 meters north, then 5 meters south, you've traveled a distance of 10 meters. But your displacement is 0 meters because you end up back where you started.
