...opinion of astronomers. Sir John F. Herschel, in referring to Newton's law of gravitation, says — " Every particle of matter in the universe attracts every other particle with a force directly proportioned to the mass of the attracting partiele, and inversely to the square of the distance...

...when you see it on record. It is the theory of universal gravitation — the grand generalization, that every particle of matter in the universe, attracts every other particle of matter with a force or power directly proportioned to the quantity of matter in each, and decreasing...

...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...

...future advancement in the study of Celestial Mechanics. Already the sublime truth announced by Newton, that every particle of matter in the universe attracts every other particle with a force varying reciprocally as the squares of their mutual distances, has been realised in tbe motions of...

...leave the labors of a few computations to a friend. When they were completed, the law which proved, that "every particle of matter in the universe, attracts every other particle of matter, with a force or power, directly proportioned to the quantity of matter. in each, and decreasing...

...Apple to his feet and established the memorable, universal Law ; namely, that, every individual partick of matter in the universe attracts every other particle, with a. force, directly as the mass of the attracting particle, and inversely as the squares of their distances. And...

...What, then, is the final conclusion of this magnificent theory ? The conclusion is, that every particle in the universe attracts every other particle with a force which is directly proportionate to the mass of the attracting particles, and inversely proportionate to the...

...velocity of projection, and that the magnitude and form of the orbit is calculable. He who announced that every particle of matter in the universe attracts every other particle, with a force varying inversely as the square of the distance, and directly as the mass, ivas not ignorant of, or...

...which counteracts the centrifugal force of bodies in motion. Stated abstractedly, that law is this : " Every particle of matter in the universe attracts every other particle, with a force di;ly proportioned to the mass of the attracting particle, .- inversely to the square of the distance...

...mechanical forces. 1. Universal gravitation. — The principle known as universal gravitation is this, that every particle of matter in the universe attracts every other particle with a force which varies inversely as the square of the distance, ie, when the distance is doubled, the force is reduced...
