1·Is that causes by gravitational attraction?
这是由万有引力作用产生的吗？
2·Which of them show the effect of gravitational attraction?
以下哪项显示地心引力的效应？
3·So, he was able to explain this using his laws for gravitational attraction.
他根据自己提出的万有引力定律，解释这一定律。
4·The craft will acquire sufficient velocity to escape the sun's gravitational attraction.
飞船将会以足够快的速度来脱离太阳的引力。
5·And we have also seen gravitational attraction in space, and I will let you look at your notes for that.
我们还学习过空间中的万有引力，关于这个知识点，大家翻一翻笔记。
6·Many asteroids are weakly bound piles of rubble, held together by their own minute gravitational attraction.
大多数的小行星都是由碎石组成，而这些碎石靠着自身之间微弱的万有引力结合在一起。
7·The force of gravitational attraction between two bodies decreASe AS the distance between them increASes.
两物体之间的引力随着两物体之间的距离增大而减小。
8·The force of gravitational attraction between two bodies decrease as the distance between them increases.
如将距离增大两倍，则其万有引力就减小九分之八。
9·Galactic matter orbits around a central point because its mutual gravitational attraction creates centripetal forces.
由于星系的重力产生了向心力，所以星系的物质体是环绕着一个中心点运行的。
10·Better to knock it off course or tow it away using the gravitational attraction of a spacecraft sent to divert it.
最好让其改变航线或者利用太空飞船的万有引力来将它拖走。
