\begin{definition}[Definition:Displacement]
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.
