Relative velocity is the vector differnce of 2 velocities in same coordinate system.

It is given by eqn. V_AB = V_A - V_B.

The velocity of an object only really has meaning when it is expressed relative to a set of axes or frame of reference. We usually consider the motion of objects moving relative to the Earth, but since the Earth is orbiting the Sun and the Sun is moving through the Galaxy this is a purely arbitrary concept. When dealing with more than one body in motion the problem is complex. We should always specify the frame of reference relative to which an object is moving. The velocity of one body relative to another is called its relative velocity
