Phunny Physics Take II
While Newton's laws are adequate to describe the motion of an idealized object's motion in an inertial frame they proved inadequate to characterize the motion of rigid bodies and deformable bodies, necessitating the development of more generalized laws of motion for rigid bodies by Euler based on Newton's groundwork.
If a body is represented as a continuum of discrete particles, each governed by Newton’s laws of motion, then Euler’s laws can be derived from Newton’s initial concepts.
Likewise, while Newtonian mechanics is a useful approximation for objects moving at speeds much slower than the speed light, for moving frames of reference and objects moving at faster speeds, it has been superseded by Einstien's Special Relativity; and for objects on the atomic scale Einstien's General Relativity and quantum mechanics provide the better heuristics.
This is not to say that Newton's ideas which first appeared in his Philosophiæ Naturalis Principia Mathematica in 1687 (along with the Calculus) were wrong, as they served to successfully describe and predict planetary motions and the orbits of thier satellites, and provided the basis for the more accurate and comprehensive theories that were predicated on his initial concepts, but that they were nascent.
Newtonian mechanics served as the precursor to the more highly developed ideas fostered just by his having proposed them in the first place.

With this in mind and mayhaps a little tongue-in-cheek, this blog entry serves as a convenient cross-reference between more familiar verbage and concepts we come across in our common experience and what A Page In The Life tries to tease out from the Quran as Knowledge Object.

`Terrific,' said Arthur.
`But don't you see what this means?'
`Yes. We are going to die.'

`APART from that?'

`You have to get to know her,' said Arthur.
`She eases up does she? '
`No,' said Arthur, `but you get a better sense of when to duck.'"
