...itself, acts as if all its mass were concentrated at its center. Thus, two spheres of uniform material attract each other with a force proportional to the product of their masses divided by the squares of the distance between their centers. Gravitation appears to act Instantaneously....

...were manifest ; and the hypothesis was that their motions might be due to their attracting one another with a force proportional to the product of their masses and inversely proportional to the squares of the distances between them. In the Ptolemaic Astronomy, again, there...

...two magnetic poles of strength m units and m' units respectively at a distance r cm. apart repel or attract each other with a force proportional to the product of their FIG. strengths divided by the square of the distance apart. 62. Induced Magnetism. — Magnets are...

...astronomy. All its facts are accounted for by Newton's law of gravitation, which states that two heavenly bodies attract each other with a force proportional to the product of their masses, and inversely proportional to the square of their distance apart. Further research into the nature of gravitational...

...— Newton's law of gravitation asserts that every heavenly body attracts every other heavenly body with a force proportional to the product of their masses, and inversely proportional to the square of their distance apart. This law has, so far, been confirmed for distances...

...be inferred the law of universal gravitation. Every particle of matter attracts every other particle with a force proportional to the product of their masses and inversely as the square of their distance apart. This law can be pretty clearly established for all bodies constituting the solar...
