Newton's law of gravitation: see gravitation gravitation, the attractive force existing between any two particles of matter .
The Law of Universal GravitationSince the gravitational force is experienced by all matter in the universe, from the largest galaxies down to the smallest particles, it ..... Click the link for more information. . Newton's law of gravitationStatement that any particle of matter in the universe attracts any other with a force (F) that is proportional to the product of their masses (m1 and m2) and inversely proportional to the square of the distance (R) between them. In symbols: F = G(m1m2)/R2, where G is the gravitational constant. Isaac Newton put forth the law in 1687 and used it to explain the observed motions of the planets and their moons, which had been reduced to mathematical form by Johannes Kepler early in the 17th century. Newton's law of gravitation [′nüt·ənz ′lȯ əv ‚grav·ə′tā·shən] (mechanics) The law that every two particles of matter in the universe attract each other with a force that acts along the line joining them, and has a magnitude proportional to the product of their masses and inversely proportional to the square of the distance between them.

| Another consequence of gravity having an unrecognized short-range component would be that the exponent in Newton's law of gravitation (i. The finding demonstrated that the pairs of stars move in accordance with Newton's law of gravitation, "extending [the law] farther into space than ever before," notes DeVorkin. Applying Newton's law of gravitation, the scientists then estimate the amount of mass that must be present to account for such rapid motion. |
