Abstract (englisch):

We learn and teach classical mechanics essentially as it was developed by Newton. The theory is more than 300 years old, but still useful for many pur- poses. However, even in contexts where it produces correct results, it has a flaw: it uses actions at a distance. In addition, it is not able to describe the transport and storage of energy in the gravitational field locally.
The general theory of relativity not only eliminated the actions at a distance of Newtonian mechanics, but also predicted phenomena which the Newtonian the- ory of gravitation could not explain. However, for solving many problems and for an introduction of gravitation in a standard lecture, general relativity is too complicated, mainly because of the tensor calculus.
To bridge the gap between these two theories we propose to use Heaviside’s the- ory of gravitoelectromagnetism. This theory has the same structure as Maxwell’s electromagnetism. It has the advantage that it does not describe forces as actions at a distance and that it allows to establish a local energy balance.
We discuss the limits of applicability of Heaviside’s theory. It turns out that be- sides the well-known condition low field/slow motion, another condition must be satisfied. ... mehr
