Title: | Direct calculation of length contraction and clock retardation | Authors: | Redžić, Dragan | Keywords: | Relativistic processes | Issue Date: | 1-Jan-2015 | Journal: | Serbian Astronomical Journal | Abstract: | For simple electromagnetic models of a rod and a clock, a change of shape of a rod and of the rate of clock when they are set in uniform motion is calculated exactly, employing the correct equation of motion of a charged particle in electromagnetic field and the universal boostability assumption. Thus it is demonstrated that, for the simple system considered, the length contraction and clock retardation can be interpreted as dynamical cause-and-effect phenomena, and not as kinematical effects as usually construed in conventional presentations of Special Relativity. It is argued that the perspective relativistic change of an object (corresponding to observations from two inertial frames), while certainly being an acausal effect, has a dynamical content in the sense that it is tantamount to an actual dynamical change of the object in one frame. |
