FS:
In light of your example, would you care to comment on the logic chain posted immediately prior to your post? From what I gather, you have a disagreement with step 13 onwards. Accordingly, I have a further question for you: if you were sitting on a rollerskate (rather than a seat) when you accelerated your big V8 RV, you would have to hold on tight to avoid being flung backwards. Is this a force, or a reaction?
