[grav-i-tey-shuh n] /ˌgræv ɪˈteɪ ʃən/
a sinking or falling.
a movement or tendency toward something or someone:
the gravitation of people toward the suburbs.
of, relating to, or involving gravitation
the force of attraction that bodies exert on one another as a result of their mass
any process or result caused by this interaction, such as the fall of a body to the surface of the earth
1640s in physics sense, also figurative, from Modern Latin gravitationem (nominative gravitatio), noun of action from past participle stem of gravitare (see gravitate). Related: Gravitational.
gravitation grav·i·ta·tion (grāv’ĭ-tā’shən)
The force, first described mathematically by Isaac Newton, whereby any two objects in the universe are attracted toward each other. Gravitation holds the moon in orbit around the Earth, the planets in orbit around the sun, and the sun in the Milky Way. It also accounts for the fall of objects released near the surface of the Earth. The modern theory of gravitation is the general theory of relativity.
noun, Astronomy. 1. the final stage of stellar evolution in which a star collapses to a final state, as a white dwarf, neutron star, or black hole, when the star’s nuclear reactions no longer generate enough pressure to balance the attractive force of gravity. 2. the initial stage of stellar evolution in which interstellar gases […]
