Velocity-addition formula

In relativistic physics, a velocity-addition formula is an equation that specifies how to combine the velocities of objects so that no combined speed can exceed the speed of light. Such formulas apply to successive Lorentz transformations and so relate different reference frames; combining velocities this way also produces a kinematic effect called Thomas precession, in which successive non-collinear Lorentz boosts act like a rotation of the coordinate system combined with a boost.
