Wiktionary
n. (context physics English) a very long-range, but relatively weak fundamental force of attraction that acts between all particles that have mass; believed to be mediated by gravitons
WordNet
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 attraction]
Usage examples of "gravitational force".
Since we now know that feeling accelerated motion is the same as feeling a gravitational force, the present situation of George on the cable involves the same principle, and once again we see that George's clock, and everything else in his life, runs in slow motion compared with Gracie's.
For example, the gravitational force of the sun on the earth was pictured in particle theories as being caused by the emission of a graviton by a particle in the sun and its absorption by a particle in the earth (Fig.
These are caused by the changes in gravitational force with distance—.
Some fascinating work is going on that interprets the gravitational force as a residual effect of electromagnetism—.
The gridded surfaces of two circular tables had been made magically elastic in such a way that placing small spherical weights on them produced funnel-shaped indentations, with the effects of the gradient in each case mimicking the gravitational force around a star or planet in the different universes.
Their enormous masses and velocities largely exempted them from the gravitational force that curved the paths of the Sun's family of planets.
Now we know that the inner coherence of a physical body is due to its point-relationship, that is to the gravitational force bound up with it.
The electromagnetic force between a proton and an electron is 1040 (1 followed by 40 zeros) times as great as the gravitational force between them.
If r is the distance between the centers of two masses, we say that the gravitational force varies as 1/r2.
We act as though we were merely trying to make the piece of lead we are working with stop attracting, stop being a source of gravitational force, but in order to do that we have to overcome locally Earth's field, the Sun's field, and all the fields of the universe.
In other words, it remains always at a constant intensity of the planetary gravitational force which means it keeps us at a nearly constant height above sea level.
Photinos - the dark matter particles - interacted with normal matter only through the gravitational force, so that even to Paul the halo was like the faintest mist.
The intensity of the gravitational force at the center of the dark ellipse shape could be measured, if not designated, by the lines on the screen.
First, the downward gravitational force decreases as the square of the distance from the center of the Earth.
