Question

8. Define relative velocity? What is the relative velocity of two bodies having equal
velocities moving in same direction?​

Answer 1

Answer:

The velocity of an object A relative to another object B is the velocity that object A would appear to have to an observer moving with B. One obvious example of this is to work out how long it will take two objects travelling along a line at different velocities to collide – like cars on a road

So, when two bodies move with the same velocities, v A = v B. So, for case1: If the bodies move in the same direction, the relative velocity is zero. This means that both see each other at rest. However, (case 2:) if they move in opposite directions, the relative velocity is twice the velocity of the bodies
