...over." Besides this, and apparently in order to further explain himself, Newton gives examples : " Impressed forces are of different origins ; as from...percussion, from pressure, from centripetal force." Reading this as an ordinary piece of English, we understand that Newton's impressed force is in an...

...action is over. For a body maintains every new state it acquires, by its force of inertia only. But impressed forces are of different origins, as from Percussion, from Pressure, from Centripetal Forces. For a Cartesian the fourth definition was almost acceptable. For him, impressed force had no...

..."consists in the action only, and remains no longer in the body when the action is over." Moreover, "impressed forces are of different origins, as from...percussion, from pressure, from centripetal force" (Newton [1960] [1686], Definition IV). Gravity was the paradigm. True, the force of gravity always...

But impressed forces are of different origins, as from...percussion, from pressure, from centripetal force. (Def. 4) A centripetal force is that by which bodies are drawn or impelled, or in any way tend toward...

But impressed forces are of different origins, as from...percussion, from pressure, from centripetal force. Having defined the notions of mass, momentum, inertia, and force, Newton proceeded with the formulation...

...definition of an impressed force. At the end of his discussions of this definition he wrote : 'But impressed forces are of different origins, as from...percussion, from pressure, from centripetal force.' Since the second law is a law about impressed forces, it has to cover all three hinds of impressed...

...but always present - impressed force is by its nature episodic. The explanation ends with the remark, "Impressed forces are of different origins; as from...percussion, from pressure, from centripetal force." The phraseology here - a force said to be "from" another (kind of) force as its "origin" - is rather odd....

[...] But impressed forces are of different origins as from...percussion, from pressure, from centripetal force. The third definition has established the standard of motion, and the fourth definition identifies force...
