Ok, but you made a comment stating that what I said is inaccurate. It's not. It's just a different philosophy for analyzing rotating systems. And importantly, it's how Karman conceptualized his dynamic model for an aerodynamic space-plane that led to the derivation of the Karman Line in the first place. Describing the Karman Line through such a rotational reference is perfectly acceptable. There's no reason at all to keep our thinking about free-body diagrams and physical models to strictly inertial frames. Doing so in no way makes a conceptual framework more accurate than any other. I really hate this way thinking about centrifugal force and rotational frames. It's a breeding ground for pointless internet arguments like this one instigated by the most frustrating of pedantry. Spreading this idea that using centrifugal force is somehow wrong only acts to restrict understanding of physics. It also handicaps you from solving problems in ways that could be better served by changing frames.
