1·The clump weight provides a gravity force.
配重块提供一重力。
2·The gravity force of a space object depends on its mass.
空间物体的重力取决于物体质量。
3·The more massive an object, the stronger the gravity force applied to it.
质量越大的物体所受到的重力也就越大。
4·It is a space rock captured and now held in orbit by the gravity force of Mars.
它只是星际空间的一块岩体，受火星引力作用而被吸引住，并沿着轨道环绕火星运动。
5·We imagined that a variety of radio sources morphology are the result due to the transversal wind and the sub-gravity force.
认为各种各样的射电源形态的出现可能是存在横向风和次引力中心的结果。
6·Newton proved his idea by measuring how much gravity force would be needed to keep the moon orbiting the Earth. Then he measured the mass of the Earth and the moon, and the distance between them.
牛顿要通过测量月球按轨道围绕地球运转需要多大的力量，来证明他的理论，于是，他测量月球和地球的质量，以及他们之间的距离。
7·When plants shoot on the earth, their stems grow away from the gravity (the force that keeps your feet on the ground), and so they always shoot upwards.
当植物在地面上生长时，它们的茎生长得方向与重力相反（重力是让你的脚留在地面上的力量），因此它们总是向上生长。
8·Upwards of a billion stars in our galaxy have burnt up their internal energy sources, and so can no longer produce the heat a star needs to oppose the inward force of gravity.
在我们的星系中，超过10亿颗恒星已经耗尽了它们的内部能量来源，因此无法再产生恒星所需的热量来对抗向内的引力。
9·The poet, after all, is subject to gravity in Frost, to the force of the earth.
这个诗人，弗罗斯特，终究还是受制于地心引力，受制于地球的力量。
10·The growth of these structures was initially driven only by the attractive force of gravity, but then later there was competition with the repulsive force of dark energy.
这些宇宙空间中的结构最初是由于万有引力的作用开始进化的，但不久之后就有暗能量的反重力作用与其对抗。
