[Yoda]

Yoda - you asked-: "In your opinion -- just asking -- does your explanation above differ from the basic laws Sir Isaac Newton expressed in his Philosophiæ Naturalis Principia Mathematica (1687)?: "

I have not read Newton's work so I do not know . . . ".

Thanks, Jeff. I appreciate your response.

Question: Do you feel your answer differs from a conventional understanding of Sir Isaac's work (as explained in your posted links or otherwise)? From your post, apparently not.

This is not a trick question. I only want to know if you feel you are illustrating his principles with your models (and explaining them in your own words) -- nothing wrong with that and a lot to be commended -- or if you are 'plowing new ground'.
