(1) A figurative movement toward some attraction
"The gravitation of the middle class to the suburbs"
(2) Movement downward resulting from gravitational attraction
"Irrigation by gravitation rather than by pumps"
(3) (physics) the force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface
"The more remote the body the less the gravity"
"The gravitation between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them"
"Gravitation cannot be held responsible for people falling in love"--Albert Einstein
- the fundamental force of attraction that exists between all particles with mass in the universe. It is the weakest of the four forces, and possesses a gauge boson known as the graviton. See also gravity.
