gravity is a kind of fundamental force 2001-09-27 09:29:56.0
has definition The weakest of the four fundamental forces of nature, the gravitational force between any two masses is proportional to the product of the masses and varies inversely as the square of the distance between them. The other three fundamental forces are the electromagnetic force and two kinds of nuclear forces. (See electromagnetic force; nuclear forces.) has source: Lightman, A., Brawer, R. 1990 The Lives and Worlds of Modern Cosmologists, Harvard University Press, 2001-09-27 09:29:56.0
has definition The weakest of the four fundamental forces of nature. Described by Newton's universal theory of gravity, and subsequently by Einstein's general relativity. has source: Greene, B. 1999 The Elegant Universe, W.W. Norton and Co., New York, 2001-09-27 09:29:56.0
has definition As described first by Isaac Newton, gravity is a force that exists between bodies of any mass whatever (from particles to stars) in proportion to the product of their masses, and in inverse proportion to the square of the distance between them. The weakest of the four natural forces (the other three being the electromagnetic and the two nuclear interactive forces), its real nature is still not fully understood. Einstein's General Theory of Relativity presented another viewpoint. has source: Abbot, D. 1984 Astronomers, Peter Bedrick Books, New York, 2001-09-27 09:29:56.0
has definition Fundamental force of nature, generated by all particles that possess mass. Interpreted by means of Newtonian mechanics or by the general theory of relativity. has source: Ferris, T. 1988 Coming of Age in the Milky Way, Morrow, 2001-09-27 09:29:56.0
has definition The universal ability of all material objects to attract each other; F = Gm₁m₂ / r². has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press, 2001-09-27 09:29:56.0
has definition The mutual attraction between any two masses, as was first described accurately by Newton. Gravity appears strong because it has infinite range and it is always attractive (except for a false vacuum), but on a subatomic level gravity is the weakest of the known interactions; the gravitational force between a proton and an electron is 2 × 10³⁹ times weaker than the electrical attraction. has source: Guth, A.H. 1997 The Inflationary Universe, Addison-Wesley, 2001-09-27 09:29:56.0
has definition One of the four fundamental forces of nature, and the one most different from the other three. has source: Clark, S. 1997 Towards the Edge of the Universe, Wiley, 2001-09-27 09:29:56.0
has definition In Aristotelian physics, an innate tendency of the elements earth and water to fall. In Newtonian physics, the universal, mutual, attraction of all massive objects for one another; its force is directly proportional to the mass of each object, and decreases by the square of the distance separating the objects involved.
In Einstein's general relativity, gravity is viewed as a consequence of the curvature of space induced by the presence of a massive object. In quantum mechanics the gravitational field is said to be conveyed by quanta called gravitons.
