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]
Usage examples of "gravitational attraction".
If the average matter density is less than the critical value, the gravitational attraction will be too weak to stop the expansion, which will continue forever.
The gravitational attraction between Nemesis and the Sun is terribly weak, so weak that the gravitational perturbations of nearby stars would make the orbit unstable.
As we get farther out, our weight will decrease as the gravitational attraction drops off, but we would need such vast amounts of energy that they are beyond human conception.
We'll have to use the gravitational attraction of that sun to help us.
And the closer that one can come to the center of gravitational attraction when applying a velocity boost, the more gratifying the result.
Stars don't sit motionless in space, they generally seem to be heading somewhere, presumably as the result of the gravitational attraction of the rest of the universe, which is lumpy enough to pull different stars in different directions.
Well, simplified, it is the effect gravitational attraction has on matter when taken to the extreme.
It keeps expanding and contracting to strike a balance between its rotantional velocity and the gravitational attraction of the center.
Most briefly the combined drive and guidance system of the disk functioned by means of the focusing of gravitational sensors on material objects and using the gravitational attraction of these objects while in effect screening out the attraction of others.
But if you let them move only in response to the gravitational attraction of another massive object, they always move with the same acceleration, to a very high level of precision.
It will move in the direction of gravitational attraction, sliding through ordinary matter, until such time as a continuous medium of relatively high density exerts sufficient friction to stop it.
Venus and Earth and all the planets act like giant vacuum cleaners of space, pulling into themselves all the space debris and meteors within millions of miles by their gravitational attraction.
