In this paper we will consider the nature of electrodynamics in an absolute Euclidean space-time. Consequently, we will also consider the nature of dynamics in general. rn many respects the situation is similar to that in (electro)dynamics in the theory of relativity. In other respects there are some pronounced differences. They lead, for instance, to new kinds of modifications of the Lorentz force law as well as Coulomb's law. We will show how easily the null result of Trouton's experiment can be understood by means of this new kind of electrodynamics. In addition, we will investigate the consequences of the reversal of proper time. It turns out that our theory leads to the prediction of the possible existence of particles with new electromagnetic characteristics. Finally, we will make a few remarks about the concept of an internal space in an absolute Euclidean space-time.
