论相对静止物体相对速度为零的充要条件

On the Plenty Reguisite Condition of Zero Relative Velocity of Relatively Still Object

就人们普遍认为相对静止的两个物体相对速度为零提出了质疑 。

The generally accepted concept that relative velocity of two relatively still objects is zero was questioned.This paper demonstrated that the plenty requisite conditions zero velocity in above condition is as follows:both object still or traslation in the selected referencd coordinate.
