逃逸速度就是一个物体的速度，比如说，从加农炮中射出的最小初始速度，这样这个物体以后就可以自己脱离地球的引力。
Escape velocity is simply the speed of an object that's shot out of a cannon the minimum initial speed so that the object could later escape Earth's gravity on its own.

这两个组织也有可能想出办法解决更高的行进速度，这样就能去到离地球更远的地方。
Both organisations would also have the chance to address the problem of a higher re-entry speed which is accumulated on trips further away from the Earth.
这些卫星位于地球上方3.588万公里，运行速度为每秒3.07公里，而阿波菲斯行星则预计将在距离地球3.25万公里的地方经过。
Those satellites travel at 3.07 kilometres a second (1.9 miles), at up to 35,880 kilometres above earth -- and the Apophis asteroid will pass by earth at a distance of 32,500 kilometres.
斯特里克林拉动弹射拉手的那一刻，飞机离地面就只剩下140英尺（约42.7米，14层楼高——译者注），其瞬时速度仍达260英里/小时（约116米/秒）仅仅过了几毫秒，也就是斯特里克林真正离开飞机的那一刹那，飞机其实又下降了100英尺。
When Stricklin pulled the handle, his plane was 140 feet off the ground, flying mostly level at 260 mph. In milliseconds, the plane fell another 100 feet before Stricklin actually left it.
