An airplane, a car and a man all move in the same direction, but with different velocities. How will their movements be recorded by different observers? |

The relative velocity of two bodies is the velocity of one of them, measured in a frame of reference attached to the other body. If the first body`s velocity is V1, and the velocity of the frame of reference with respect to the earth is V0, then the relative velocity equals to V1- V0. |
