Editing Euclidean vector (section)

===Examples in one dimension===
Since the physicist's concept of [[force (physics)|force]] has a direction and a magnitude, it may be seen as a vector. As an example, consider a rightward force ''F'' of 15 [[Newton (unit)|newtons]]. If the positive [[Cartesian coordinate system|axis]] is also directed rightward, then ''F'' is represented by the vector 15&nbsp;N, and if positive points leftward, then the vector for ''F'' is &minus;15&nbsp;N. In either case, the magnitude of the vector is 15&nbsp;N. Likewise, the vector representation of a displacement Δ''s'' of 4 [[meter (unit)|meters]] would be 4&nbsp;m or &minus;4&nbsp;m, depending on its direction, and its magnitude would be 4&nbsp;m regardless.
