Description
The aim of this contribution is to show a transition in the notion of interaction among bodies from early Newtonian to Post-Newtonian theory of (no-relativistic) mechanics. In Newton’s early mechanics, the two notions of impenetrable body or solid and interaction by shock or contact had the role of elementary concepts. The interaction at a distance had the value of phenomenological model, useful to describe the measurable effects of accelerations of separated (in space) bodies. In the post-Newtonian mechanics, the notion of interaction at a distance assumes the value of fundamental interaction as can be deduced in the framework of massive ideal point-like interacting particles.
