Its oscillation depends on the strength of the gravitational field. 它的摆动取决于重力场的力。If a spacecraft travels faster than 11 km a second, it escapes the Earth's gravitational pull. 如果一架宇宙飞船飞行超过每秒11公里，它就能摆脱地球引力。It is the gravitational interaction with planets, ...

(redirected from Gravitational pull)Also found in: Thesaurus, Medical, Encyclopedia. grav·i·ta·tion (grăv′ĭ-tā′shən) n. 1. Physics a. The natural phenomenon of attraction between physical objects with mass or energy; the weakest of the four fundamental forces of nature. Also...
2. A slow gyration of Earth's axis around the pole of the ecliptic, caused mainly by the gravitational pull of the sun, moon, and other planets on Earth's equatorial bulge. 岁差地球中轴绕黄道极的缓慢旋转,主要由于太阳、月亮和其它星体对地球赤道降起带的重力作用而造成 ...
According to astronomers, new planets continue to be discovered as scientists measure the slight wobble—caused by the gravitational pull of the planet—of the distant star the planets orbit. 天文学家报道,行星围绕星体运转时,行星的引力使星体轻微颤动。 科学家借着测量外太空星体的颤动,得以继续发现新...
3、Their loveliness masks the toll exacted by thegravitationalpull of their large bodies and the strain of daily survival.(他们的可爱掩饰了引力对巨大身体的拖累和日常生活的艰辛。) 4、The earthgravitationalpotential was developed up to 11th degree and 11th order for all of zonal and tesseral harmo...
Perhaps paradoxically, they help prove that the gravitational force exists, and they offer clues as to why it has such pull. The gravitational force of federal law Those columns are the gravitational force between stars and planets to keep them in their orbits. Earth and space created in wonder...
Fling a ball hard enough, and it never returns. You don't see that happen in real life because the ball must travel at least 11.3 kilometers (7 miles) per second to escape Earth's gravitational pull. Every object, whether it's a lightweight feather or a
What are the effects of distance and mass on the gravitational pull of the planets? What is the gravitational force of Mercury? What is asteroid impact theory? What is the cosmological principle in astronomy? What is the condensation theory of the solar system?
Newton's theory of gravitation was long able to explain all observable gravitational phenomena, from the falling of objects on the earth to the motions of the planets. However, as centuries passed, very slight discrepancies were observed between the predictions of Newtonian theory and actual events...
