Definition:Displacement

Definition
The (physical) displacement of a body is a measure of its position relative to a given point of reference in a particular frame of reference.

Displacement is a vector quantity, so it specifies a magnitude and direction from the point of reference.

In Cartesian coordinates, the direction is implicit, as it occurs as a result of the combined distances from the various axes of the frame of reference.
