Noun
1. (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
2. movement downward resulting from gravitational attraction;
"irrigation by gravitation rather than by pumps"
3. a figurative movement toward some attraction;
"the gravitation of the middle class to the suburbs"
universal gravitation万有引力
1640年代物理学中,“给物体重量的力量”,也比喻为“朝向吸引中心的趋势”,源自现代拉丁语 gravitare(见 gravitate)。比较 gravity。

The first known use of gravitation was circa 1645

gravitationnoun
a force manifested by acceleration toward each other of two free material particles or bodies or of radiant-energy quanta as if they were particles (as in the bending of rays of starlight passing close to the sun) : an attraction between two bodies that is proportional to the product of their masses, inversely proportional to the square of the distance between them, and independent of their chemical nature or physical state and of intervening matter
1 Our business , then, is to overcome this action of gravitation.
所以我们必须战胜重力的作用.
2 The weight of the aircraft , due to the earth's gravitation , tends to pull the aircraft downward.
由于地球引力作用, 飞机的重量趋向于坠落.
3 But it does mean that our attempts to understand the world are reduced to the kind of thing that Newton did in case of gravitation.
但是这并没有意味着我们试图理解世界的热情有所减少,诸如牛顿对万有引力的研究一样。
4 Nudged by the gravitation of Jupiter, Mars, Venus and other planets, our world’s axial tilt and precession are always slowly shifting.
5 The cluster’s enormous gravitation field acts as a lens, warping and magnifying the light from galaxies behind it that would otherwise be too faint and faraway to see.
6 Newton’s universal law of gravitation works for the planets, but is it really universal?
7 He occupied himself by inventing the differential and integral calculus, making fundamental discoveries on the nature of light and laying the foundation for the theory of universal gravitation.
8 If this alternative gravity theory is correct, it would be a "major revolution," Loeb said, emphasizing it would be at the scale of Newton's law of gravitation and Einstein's law of gravity.
9 As Feud implies, this may have influenced his gravitation to the swans, as well as his willingness to betray them.
10 Staying true to her gravitation toward unconventional, casual styles and a love for the aviator silhouette, Diana preferred to have fun with sunglasses while guarding herself from more than just UV rays.
11 Euler also carried forward another aspect of Newton’s legacy, by showing that Newtonian theories of motion and gravitation gave incredibly accurate predictions of the motions of the Moon and other planetary phenomena.
12 For example, the earth has more matter than the moon, so the earth's pull or gravitation is stronger than the moon's.
比如,地球比月球含的物质多,所以地球的拉力或引力就比月球大。
13 Secondly, the strength of gravitation depends on the distance between the bodies.
其次,引力的强度还取决于天体之间的距离。
14 Free talks describe the observatory’s achievements, like verifying Einstein’s geometric theory of gravitation.
15 And of course that observation was central to the formulation of Kepler’s laws, which together with Galileo’s study of pendula and falling bodies, all this led to the pinnacle of the scientific revolution: Newton’s formulation of classical mechanics and the laws of gravitation.
16 Once the size of the universe is doubled both matter energy and gravitation energy double correspondingly.
当宇宙的尺度加倍,物质和引力能都加倍——这样,零的两倍仍为零.
17 With his general theory of relativity that was published in 1915, Einstein revolutionised modern physics when he first described gravitation as a geometric warping of space and time, a finding that remains valid.
18 “Underwriting a new issuer can be a slow process. A bank’s existing relationship will likely already have an internal rating and there is a natural gravitation to existing clients,” said Bettwy.
19 Many people had seen apples fall, but it took the observant eyes of Newton to discover the law of gravitation from this common occurrence.
许多人都看过苹果落地,但是需要牛顿的善于观察的眼睛去从平常的现象中发现万有引力定律。
20 The law of gravitation explains many phenomena not previously, understood.
引力定律解释了许多以前所不能理解的现象.
