More on Relative Vectors and Velocities
If a particle North or South, East or West of another particle, then we can write down conditions that the position vectors must satisfy.
If the particle A is North of particle B then
and
If the particle A is East of particle B then
and
Suppose then that
When A is North of B, the
(or
) components are equal:
When A is East of B, the
(or
) components are equal:
