On the Concept of Integrality in the Theory of Special Relativity
Lorenzo Mencherini
Keywords: theory of special relativity, velocity, integrality
We say that a body is integral in a given reference frame if the coordinates of its points are constant in time.
Given any two bodies A and B, we ask what kinematic relationship there is between them.
We assume that A moves at velocity v different from O with respect to B: hence we can say equivalently that B moves with respect to A at velocity -v because of the principle of relativity. In this case then the subject is of no importance.
