Relative velocity is defined as the velocity of a particle with respect to another particle.
It is given by,
.
More: For example, I am moving to South direction in a straight road with a uniform speed of 2 m/s, and a bus is coming near me at a speed of 10 m/s (north).
So, relative velocity will be 12 m/s.
As, V = 2 - (- 10) m/s = 12 m/s.
