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.
