Newton's Third Law does not say a reaction force exists in isolation or as a sequence. It says that whenever a force exists between two bodies, there is simultaneously an equal and opposite reaction force. A simultaneous mutual interaction. In the worked example, bodies A and B are in contact and interacting. The 500N force A and B are exerting are the same interaction described from two perspectives simultaneously. The contact itself is the event; the equal and opposite forces are its two faces. This is why what I propose is on solid ground. It does not require an external driving force to be specified separately. The interaction between the bodies (whatever its physical origin) produces the equal opposite reaction force pair at the contact boundary by definition of Newton's Third Law. Two classical bodies making contact do not necessarily fuse into a single undifferentiated lump of matter. The framework does not claim the two bodies become one body. It claims that for the duration of the force interaction at the contact boundary, they constitute a single dynamical system with a shared acceleration. Yanick Borg -y
