Simultaneous processes in mechanics and quantum physics — •Grit Kalies¹ and Duong D. Do² — ¹HTW University of Applied Sciences, Dresden, Germany — ²The University of Queensland, Brisbane, Australia

Processes change the properties of objects. Using examples such as the lifting, acceleration or displacement of a body as well as of a quantum object, we substantiate the plausibility and advantages of replacing 'force is action' with 'process is action'. Since each process with energy transfer describes the change in one property of a macroscopic or microscopic object, simultaneous processes allow for a more detailed energetic analysis than forces. The notion of acting forces and the current general definition of work are interpreted as helpful geometric substitute concepts, which conceal the actual dynamic processes such as the momentum work that takes place at the macroscopic and quantum levels.

Keywords: interaction; process equation; quantum work; friction
