引力

Newton precisely measured the inertial mass of a great many objects (what it took to get them moving, as in getting a pendulum started) and their gravitational mass (how fast they fell to the Earth), to determine that the two forces were equal, if not equivalent, and could be canceled out when doing physics.

牛顿精确测量了很多物体的惯性质量（使物体运动的内在动力，就像钟摆开始往复的动力）和它们的引力质量（以多快的速度向地表坠落），以此来确定这两种力是均等的，如果不均等，在做物理学运算时可能就会互相抵消。

Collapsing interstellar cloud reverses its gravitational infall and expands outward into the relatively quiescent interstellar environment.

坍缩的星际云克服向内的引力而向外膨胀到较宁静的星际环境中去。

Such avelocity is on the order of the sound speed, and can be easily explained by thegravitational infall of material from the circumstellar dust shell.

这个内落运动速度值基本与声速同一量级，很容易通过引力加速拱星尘埃壳层的物质来获得。

It's a point in space where gravity grows infinitely strong.

它是宇宙中的一个点，他的引力会无穷增大。

The inherence of life is a kind of movement deviating the gravitation and flying freely.

爱因斯坦对引力的解释应该出现在任何的终极理论中。

The quest to overcome gravitation, inherently linked with ski jumping, is architecturally expressed by the cantilevering inrun of the ski jump.

寻求克服引力，内在的联系与跳台滑雪，是建筑所表达的cantilevering inrun的跳台滑雪。

The idea of an inverse-square law of gravitational force acting on the planets was in the air around Newton's time.

认为作用于行星的是平方反比定律的引力，这种看法在牛顿时代很流行。
