Composition of velocities

If the observer in S sees an object moving along the x axis at velocity w, then the observer in the S' system will see the object moving with velocity w' where

This equation can be derived from the space and time transformations above. Notice that if the object is moving at the speed of light in the S system (i.e. w = c), then it will also be moving at the speed of light in the S' system. Also, if both w and v are small with respect to the speed of light, we will recover the intuitive Galilean transformation of velocities: w' = w - v.
