Question

Explain the concept of relative velocity. ​

Answer 1

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. To you, sitting on the stationary train (A), or to a person on the platform, the moving train

B.)appears to be travelling at a velocity v,v away. However, to a person on the moving train the platform and the stationary train at the platform both appear to be moving in the opposite direction with the same speed, or to put it another way, with the opposite velocity. Really what we are measuring in all of these cases is the velocity relative to an observer.
