Work versus force: Simultaneous processes for describing interactions — •Grit Kalies1, Duong D. Do2, and Cornelia Breitkopf3 — 1HTW University of Applied Sciences, Dresden, Germany — 2The University of Queensland, Brisbane, Australia — 3Technical University of Dresden, Dresden, Germany
A consistent description of nature is an essential goal that has not been achieved by current theoretical physics, which uses four different fundamental forces to describe interactions. This could change when interactions are described by processes (work is actio) rather than by forces, not only at the macroscopic level but also at the quantum level. We discuss and contrast the two distinct concepts of interaction and interpret the idea of an acting force (force is actio) as a helpful geometric substitute, obscuring the simultaneous processes that actually take place. Using examples such as the lifting, acceleration or displacement of a body as well as of quantum objects, we demonstrate the advantages of applying process equations, including those that describe a change in the momentum of a particle or body. The results indicate that simultaneous processes allow for a more detailed energetic analysis of quantum objects and pave a path for reconciling classical thermodynamics and quantum physics towards a deterministic description of quantum objects.
