If two bodies are moving in opposite directions with non-zero velocities, which of the following statements is true?

(a) Relative velocity > Absolute velocity

(b) Relative velocity < Absolute velocity

(c) Relative velocity = Absolute velocity

(d) Relative velocity <= Absolute velocity

The question was asked by my college director while I was bunking the class.

This interesting question is from Motion in a Straight Line topic in section Motion in a Straight Line of Physics – Class 11

Correct choice is (a) Relative velocity > Absolute velocity

To elaborate: The formula for relative velocity is, Vector VR = Vector VA – Vector VB. When both the velocities are opposite in direction, the equation becomes VR = VA – (-VB). Hence the magnitudes add up making the relative velocity greater than the absolute velocity of any of the two bodies.
