gravitational attraction
     n : (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 [syn: {gravity},
          {gravitation}, {gravitational force}]
