Relative position vector

A relative position vector is a vector that defines the position of one point relative to another. It is the difference in position of the two points.The position of one point A relative to another point B is simply the difference between their positions

which is the difference between the components of their position vectors.

If point A has position components r A = (x A, y A, z A) {\displaystyle \mathbf {r} _{A}=\left(x_{A},y_{A},z_{A}\right)}

and point B has position components r B = (x B, y B, z B) {\displaystyle \mathbf {r} _{B}=\left(x_{B},y_{B},z_{B}\right)}

then the position of point A relative to point B is the difference between their components: r A / B = r A − r B = (x A − x B, y A − y B, z A − z B) {\displaystyle \mathbf {r} _{A/B}=\mathbf {r} _{A}-\mathbf {r} _{B}=\left(x_{A}-x_{B},y_{A}-y_{B},z_{A}-z_{B}\right)}
