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 whether my explanation differs from the basic laws expressed by Newton in his work "Philosophiæ Naturalis Principia Mathematica (1687)".

However, I do not think that my explanation differs from the explanations offered in these links that nmgolfer recommended - relating to the topic of Newtonian laws regarding forces and motion.

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'.

[Jeff]

No. I am not plowing new ground. I am simply using words, and pictorial examples, to explain relevant Newtoniain laws that pertain to this issue of "centripetal acceleration" (as I understand those laws).

Although, nmgolfer labels me "clueless", I believe that all my posts are fully compatible with the Newtonian laws expressed in all those links.

That's why I am very comfortable with the idea of having him dissect my opinions as thoroughly as possible. It is interesting that nmgolfer is full of bluster about my "cluelessness", but doesn't offer a detailed argument explaining why my many posted explanations are inaccurate and incompatible with Newtonian laws.

Great, Jeff. I thought that was your intent. Thanks!
