Direct calculation of length contraction and clock retardation
Redžić D.V. (Faculty of Physics, Beograd)
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 a causal
effect, has a dynamical content in the sense that it is tantamount to an
actual dynamical change of the object in one frame.
