Question

13. Define relative velocity. Write the expression for relative velocity between two objects moving in samedirection.

Answer 1

Relative velocity is defined as the velocity of object B with respect to the other object A at rest.

• It is represented by V(AB) = VB - VA.
• In other words, it is the rate of change of time and position between the velocities of two objects respectively where one is at rest and the other is moving.
• It can be represented as V = Vab + Vbc when two objects are moving in the same direction.
