grav·i·ty  (grv-t)
n.
1. Physics
a. The natural force of attraction exerted by a celestial body, such as Earth, upon objects at or near its surface, tending to draw them toward the center of the body.
b. The natural force of attraction between any two massive bodies, which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
c. Gravitation.
2. Grave consequence; seriousness or importance: They are still quite unaware of the gravity of their problems.
3. Solemnity or dignity of manner.

[French gravité, heaviness, from Old French, from Latin gravits, from gravis, heavy; see gwer-1 in Indo-European roots.]

gravity [ˈgrævɪtɪ]
n pl -ties
1. (Physics / General Physics) the force of attraction that moves or tends to move bodies towards the centre of a celestial body, such as the earth or moon
2. (Physics / General Physics) the property of being heavy or having weight See also specific gravity, centre of gravity
3. (Physics / General Physics) another name for gravitation
4. seriousness or importance, esp as a consequence of an action or opinion
5. manner or conduct that is solemn or dignified
6. (Music / Classical Music) lowness in pitch
7. (Physics / General Physics) (modifier) of or relating to gravity or gravitation or their effects gravity wave gravity feed
[from Latin gravitās weight, from gravis heavy]

gravity  (grv-t)
The fundamental force of attraction that all objects with mass have for each other. Like the electromagnetic force, gravity has effectively infinite range and obeys the inverse-square law. At the atomic level, where masses are very small, the force of gravity is negligible, but for objects that have very large masses such as planets, stars, and galaxies, gravity is a predominant force, and it plays an important role in theories of the structure of the universe. Gravity is believed to be mediated by the graviton, although the graviton has yet to be isolated by experiment. Gravity is weaker than the strong force, the electromagnetic force, and the weak force. Also called gravitation. See more at accelerationrelativity
A Closer Look With his law of universal gravitation, Sir Isaac Newton described gravity as the mutual attraction between any two bodies in the universe. He developed an equation describing an instantaneous gravitational effect that any two objects, no matter how far apart or how small, exert on each other. These effects diminish as the distance between the objects gets larger and as the masses of the objects get smaller. His theory explained both the trajectory of a falling apple and the motion of the planetshitherto completely unconnected phenomenausing the same equations. Albert Einstein developed the first revision of these ideas. Einstein needed to extend his theory of Special Relativity to be able to understand cases in which bodies were subject to forces and acceleration, as in the case of gravity. According to Special Relativity, however, the instantaneous gravitational effects in Newton's theory would not be possible, for to act instantaneously, gravity would have to travel at infinite velocities, faster than the speed of light, the upper limit of velocity in Special Relativity. To overcome these inconsistencies, Einstein developed the theory of General Relativity, which connected gravity, mass, and acceleration in a new manner. Imagine, he said, an astronaut standing in a stationary rocket on the Earth. Because of the Earth's gravity, his feet are pressed against the rocket's floor with a force equal to his weight. Now imagine him in the same rocket, this time accelerating in outer space, far from any significant gravity. The accelerating rocket pushing against his feet creates a force indistinguishable from that of a gravitational field. Developing this principle of equivalence, Einstein showed that mass itself forms curves in space and time and that the effects of gravity are related to the trajectories taken by objectseven objects without mass, such as light. Whether gravity can be united with the other fundamental forces understood in quantum mechanics remains unclear.
