...by analysing the motions of the planets on mechanical principles, that every particle of ponderable matter in the universe attracts every other particle with a force varying inversely as the square of the distance, astronomers have been ftble, in virtue of that one law of...

...and provisidwally, his law of universal gravitation, which may be tliijis abstractly stated : — " Every particle of matter in the' universe attracts every other particle, with a force directly proportioned to the mass of the attracting particle, and inversely to the square of the distance...

...instance, and provisionally, his law of universal gravitation, which may be thus abstractly stated : — " Every particle of matter in the universe attracts every other particle, with a force directly proportioned to the mass of the attracting particle, and inversely to the square of the distance...

...surface. For this purpose, he reasoned on his law of universal gravitation, which may be thus stated; ' Every particle of matter in the universe attracts every other particle, with a force varying inversely as the square of the distance.' Reasoning on this law, he calculated, from the effect which...

...from gravitation. The great Newton discovered and established the law of universal gravitation, " that every particle of matter in the universe attracts every other particle, with a force varying inversely as the square of the distance :" by which is meant, that if a body be attracted by the earth...

...matter that the earth consists of. Gravity is a real power, of whose agency we have daily experience. " Every particle of matter in the universe attracts every other particle, with a force directly proportioned to the mass of the attracting particle, and inversely to the square of the distance...

...that case, the general law applies in its strict wording." — Sir John Herschefs Astronomy p. 237. " Every particle of matter in the universe attracts every other particle with a force directly proportioned to the mas of the attracting particle, and inversely to the square of the distance...

...constitution; this being, of course, only a particular case of Newton's law of gravitation, which tells us that every particle of matter in the universe attracts every other particle with a force which depends on their masses and on the distances which separate them; the attraction being proportionately...

...gravitation and attraction, by which all bodies, liquid or solid, are governed. Newton's words are — " Every particle of matter in the universe attracts every other particle with a force directly proportioned to the mass (and density) of the attracting particle, and inversely to the square...
