Question

what is relative velocity with necessary equations

Answer 1

Relative Velocity Formula

Let us consider two bodies A and B which are moving relative to each other. The relative velocity is the velocity that the body A would appear to an observer on the body B and vice versa. Mathematically speaking the relative velocity is the vector difference between the velocities of two bodies.

Relative velocity = velocity of the body A – velocity of the body B

The equation is:

vAB = vA – vB
