| has gloss | (noun) a rate that is rapid speediness, rapidness, rapidity, quickness, celerity |
| has gloss | eng: In relativity rapidity is an alternative to speed as a framework for measuring motion. The main advantage of rapidities is that they are simply additive (even at relativistic velocities), unlike speeds. For low speeds, rapidity and speed are proportional, but for high speeds, rapidity takes a larger value. The rapidity of light is infinite. Rapidity can also link geometric techniques to Minkowski diagrams. The rapidity concept is not widely (nor fashionably) used; speed has the advantage of more direct measurability. |

| has gloss | fin: Rapiditeetti on eräs menetelmä mitata liikettä nopeuden sijasta. Kun liike on hidasta, rapiditeetti vastaa suuruudeltaan nopeutta, mutta liikkeen ollessa hyvin nopeaa, rapiditeetti saa nopeutta suuremman arvon. Kun tarkastellaan valonnopeudella kulkevaa kappaletta, rapiditeetti on arvoltaan ääretön. |

| has gloss | fra: En relativité restreinte, la rapidité est un substitut à la vitesse comme mesure du mouvement. A faible vitesse, la rapidité et la vitesse sont proportionnelles, mais la rapidité diverge à haute vitesse pour tendre vers linfini quand la vitesse approche de la vitesse de la lumière. Lintérêt de la rapidité vient du fait quelle est simplement additive par changement de référentiel, quand les vitesses sont parallèles, alors que la formule pour les vitesses correspond à une formule de trigonométrie hyperbolique. La rapidité permet aussi dexprimer les transformations de Lorentz comme rotation hyperbolique dans l'espace de Minkowski. |

| has gloss | pol: Pospieszność (oznaczana symbolem y) – bezwymiarowa wielkość fizyczna używana w szczególnej teorii względności zdefiniowana przez :: y = \mathrmartgh}\left(\fracv}c}\right) gdzie : v jest prędkością, : artgh – area tangensem hiperbolicznym. Pospieszność jest związana z czynnikiem Lorentza wzorem :: \gamma = \cosh \left( y \right) Pospieszność jest wielkością addytywną przy transformacji Lorentza (jak prędkość przy transformacji Galileusza), dzięki czemu jest użyteczna w obliczeniach. Jej wartość zmienia się od -\infty dla v = –c do \infty dla v = c. |

| has gloss | rus: Быстрота́ (англ. rapidity) — в релятивистской кинематике монотонно возрастающая функция скорости, которая стремится к бесконечности, когда скорость стремится к скорости света. В отличие от скорости, для которой закон сложения нетривиален, для быстроты характерен простой закон сложения («быстрота аддитивна»). |
