That means its escape velocity gets higher and higher.

这意味着它的逃逸速度会越来越高。

Give it enough energy and it will achieve escape velocity and fly away.

给它足够多的能量，它就会达到脱离速度，飞走。

As it approaches the Earth, our planet's gravity accelerates it an additional 11 kilometers per second — Earth's escape velocity.

当它接近地球时，地球的引力使它的速度又增加了11千米/秒——这是地球的逃逸速度。

The rock can escape, moving away forever, so we call this the escape velocity.

石头就会逃逸，越来越远，永不停止，我们称这个速度为逃逸速度。

When it hits the planet it'll be moving at escape velocity, that same 11 kilometers per second.

当它落到地球上时的速度就是逃逸速度，同样是11公里每小时。

Less obviously, the smaller the radius, the stronger the gravity and the greater the escape velocity, too.

容易忽略的是，行星的半径越小，它的引力和逃逸速度也变得越大。

Conceptually, it's a lot like escape velocity.

从概念上讲，它很像逃逸速度。

But some are likely to be cancelled-as happened on May 1st to a project in Alberta, CCS is thus having difficulty reaching escape velocity.

很有可能取消一些装置的建造，因为五月一日在亚伯达的一项工程中发现CCS在达到脱离速度方面存在难度。

And if I give it a little sideways kick, it'll miss the Earth but still pass us at escape velocity.

如果我稍微侧向扔一点，它就会错过地球，但仍然以逃逸速度经过我们身边。

The escape velocity of an object like a planet or star depends on how much mass it has and how big it is.

行星或恒星等物体的逃逸速度取决于它的质量和大小。
