which defines displacement

Displacement is a vector quantity that refers to "how far out of place an object is" in a specific direction; it is the object's overall change in position. It's not just the distance the object traveled, but also the direction. For example, if you walk 10 meters east, then 10 meters west, your total displacement is 0 meters, because your position hasn't changed. But your total distance traveled is 20 meters.

Here are the steps to calculate displacement:

1. Identify your starting point and your ending point.
2. Determine the straight-line distance between these two points. This is not the path you traveled, but the direct line from start to end.
3. Determine the direction from your starting point to your ending point.
4. Your displacement is this distance, in this direction.

For example, if you start at the point (0,0) on a graph and move to the point (4,3), your displacement is 5 units (the hypotenuse of a 3-4-5 right triangle), in the direction from (0,0) to (4,3).
