This Demonstration shows the RhodesвЂ“Semon construction in the PoincarГ© disk that computes the composition of Lorentz transformations representing noncollinear relativistic velocity additions. Use the 2D sliders and to set the combined boosts. So as not to prejudge things, following Robb we will call this additive parameter producing displacements by velocity boosts the вЂњrapidityвЂќ, denoted П†. 60 The additive nature of the parameter means that the rapidity addition law is just like the velocity addition law in classical mechanics, П† 12 = П† 1 + П† 2.

The speed of light in a fluid is slower than the speed of light in vacuum, and it changes if the fluid is moving along with the light. In 1851, Fizeau measured the speed of light But following EinsteinвЂ™s special relativity, this way of measuring velocity operates correctly only for small velocities and, moreover, the speed of light is infinite! We are not measuring velocity, but rapidity! Suggested Reading [1] J McMahon, Hyperbolic Functions, John Wiley and Sons, New York, 1906.

Proper velocity is useful for comparing the speed of objects with momentum per unit rest mass (w) greater than lightspeed c. The coordinate speed of such objects is generally near lightspeed, whereas proper velocity tells us how rapidly they are covering ground on traveling-object clocks.
