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.


Dimension

The dimension of displacement is length $\mathsf L$.


Units

The SI unit of displacement is the metre.

The CGS unit of displacement is the centimetre.

The FPS unit of displacement is the foot.
