In non-relativistic kinematics, relative velocity is the vector difference between the velocities of two objects, as evaluated in terms of a single coordinate system.
For example, if the velocities of particles A and B are 
and 
respectively in terms of a given coordinate system, then the relative velocity of A with respect to B (also called the velocity of A relative to B, 
, or 
) is
and respectively in terms of a given coordinate system, then the relative velocity of A with respect to B (also called the velocity of A relative to B, , or ) is.
.
The expression "the velocity of A relative to B" is shorthand for "the velocity of A in the coordinate system where B is always at rest". Read More
