如今，即使想要知道一大块冰如何移动——或换个词讲，漂浮——是非常困难的，但众所周知冰川漂浮是由于重力。
Now, even though it may be difficult to understand how a huge mass of ice can move—or flow, it's another word for it—it's really no secret that glaciers flow because of gravity.
而用航天器撞进危险的岩石，迅速移动它的位置，然后利用另一个航天器进行微调，并利用它的重力把这块石头拖进安全轨道。
Instead, slam a spacecraft head-on into a dangerous rock to move it in a hurry, then fine-tune it with another spacecraft by using its gravity to pull the rock into a safe path.
既然重力是恒定的，我施加的力在大小上,不变，就是方向不同，无所谓我怎么移动;,答案总是,相同的。
Since gravity is a conservative force, and since my force is always the same in magnitude except in opposite direction, ; it doesn't matter how I move in; it will always come up with the same answer.
形式定义就是,它在点P的重力势能,等于我，将物体从无穷远处,移动至点P所做的功。
The formal definition is that the gravitational potential energy at a point P is the work that I, Walter Lewin, have to do to bring that mass from infinity to that point P.
因此你在一个容量的展览中移动，但是你依然能感受到重力来自于哪个机器。
So you move around the content on a display, but you can also feel where it is just from the weight of the device.
但很久前，地球表面上10英尺的人类是很标准的尺寸，因为重力远小于现在，可让身体更轻并快捷移动。
Long ago, 10-foot human forms upon the surface of the earth were the norm, and gravity far less of a pull allowing the form to weigh less and move in ease.
在云团被黑洞撕裂时的爆发的重力波辐射中或者粒子从一个轴子云团移动到另一个轴子云团时可能会揭示出轴子的存在。
The particles could also reveal their presence in bursts of gravitational waves radiated when their clouds are torn apart around the black hole or when particles move from one axion cloud to another.
触摸和持有任何地方在屏幕上移动吉米向上，在释放触摸，重力会把他放下来。
Touch and hold anywhere on the screen to move Jimmie upward, and upon releasing the touch, gravity will bring him down.
彩信，重力感应，日历，录音机，计算器，世界时钟，闹钟，股票软件，移动QQ。
MMS, gravity sensor, calendar, recorder, calculator, world clock, alarm clock, stock software, mobile QQ.
但你只能移动的石头向左或向右，其余的是高达重力！
But you can only move the stones to the left or the right, the rest is up to gravity!
这款游戏玩法很简单，只需通过重力感应左右晃动手机即可移动小船，触摸屏幕任意位置不放即可放下鱼钩，释放时鱼钩则收回。
This is a simple fishing game. Use the acceleration of the device to move the boat left or right. To cast, hold finger in any place of the screen. Release and the hook will tile back.
进入微重力环境后，重力消失促进了液态水在竖直流道上升段的移动。
In the micro gravity condition, the liquid water was removed upward by the gas phase due to the absence of gravity .
