Relativity and Cosmology


Discussion on the Relationship Among the Relative Speed, the Absolute Speed and the Rapidity

Authors: Yingtao Yang

Through discussion on the physical meaning of the rapidity in the special relativity, this paper arrived at the conclusion that the rapidity is the ratio between absolute speed and the speed of light in vacuum. At the same time, the mathematical relations amongst rapidity, relative speed, and absolute speed were derived. In addition, through the use of the new definition of rapidity, the Lorentz transformation in special relativity can be expressed using the absolute speed of Newtonian mechanics, and be applied to high energy physics. Keywords: rapidity; relative speed; absolute speed; special theory of relativity
