In physics, a velocity-addition formula is an equation that relates the velocities of moving objects in different reference frames. As Galileo observed, if a ship is moving relative to the shore at velocity v, and a fly is moving with velocity u as measured on the ship, calculating the velocity of the fly as measured on the shore is what is meant by the … Continue reading
