"A coordinate system is a mathematical concept that helps one describe points or vectors(directions) in space. A reference frame, on the other hand, is the extension of this concept to involve motion (time-dependent quantities). Coordinate Systems may be rotated/translated with respect to each other, *but* they are stationary."
I don't understand this. How can a coordinate system be rotated and translated yet be stationary. What is your definition of "motion"?
