We will , many , many times in the future , use the one over r relationship for gravitational potential energy .

将来会有很多次，用到r和，重力势能之间的关系。

We call mgy * we give that a name ," gravitational potential energy . "

我们把mgy叫做。，给它一个名字，重力势能

Y And this is y * Then the gravitational potential energy u This is u.

这是。，那么这里的重力势能，这是。

B1 which is closer to the Earth , notice that the gravitational potential energy decreases .

接近地球，，If，I，go，from，A，to，another，point，，B，prime，注意，重力势能，就会减小，我做负功。

Then this will have a positive gravitational potential energy , and this will have one that is higher than this one by this amount .

那么它将是，正的重力势能，这样的话这点，就比另一点高。

So this is a function y as a function of x and the curve itself represents effectively the gravitational potential energy .

因此这是关于y的关系，曲线本身，很有效地代表了，重力势能。

Mhy You see ? mgy is gravitational potential energy .

你们看，是重力势能。

When I 'm here , gravitational potential energy ; increases in this way ; the gravitational force is in this direction .

重力势能，这样增长，重力；，是在这个方向，当我在这里。

Determining the distribution of gravitational potential energy and its effect on active deformation is fundamental to understanding the dynamics of continental deformation .

重力位能及其重力浮力是大陆板块内部重要的构造变形动力。

So if I make a plot of the gravitational potential energy as a function of y , then I would get a straight line .

因此如果我画一张，重力势能，受y变化的图，那么会得到一条直线。

Hence , the loss of gravitational potential energy of the block equals the gain of elastic potential energy of the spring .

因此，该物块的重力势能的减少，等于该弹簧的弹性势能的增加。

Given these characteristics in surface water heat pump , it is possible to employ turbine to recover the gravitational potential energy of the water .

由于地表水源热泵系统的这些特点，因此，可以利用水轮机来回收这部分能量。

Now , what we would like to do is we would like to convert all this gravitational potential energy into kinetic energy of that disk .

现在要做的，就是要转化，所有这些重力势能，变成圆盘的动能。

There is a conversion from gravitational potential energy to kinetic energy back to gravitational potential energy , and it will come to a stop here .

这就是重力势能，转换到，动能，再回到，重力势能，最终停在这里。

A passive walker is a kind of walking robot , which can walk down a slope by its mechanical structure and gravitational potential energy .

被动步行机器人是一种仅依靠自身机械结构并利用重力势能沿斜坡步行的机器人。

M If I move from point A to point B , with a mass m in my hand , notice that the gravitational potential energy increases .

我手里物体的重量，注意，重力势能，增加了，我必须做正功。

You can install a disk in your car , which I would call , then , a flywheel , And you can convert the gravitational potential energy .

可以在车内装个圆盘，可以称之为飞轮，可以转化，重力势能。

What is important , of course , if we get the right answer for the gravitational potential energy , that when we move away from this object that the gravitational potential energy increases .

重要的是，如果我们得到了重力，势能的正确值，当我们远离这个物体，重力势能就会，增加。

Okay , my goal was to evaluate for you the gravitational potential energy the way that it is defined in general , not in a special case when we are near the Earth .

好了，我的目标是，用通常的方式，为你们评价重力势能，不是用一个特殊的，接近地球的案例。

So the slowdown , the " braking " is now done because of a conversion from your linear speed which comes from gravitational potential energy to the rotation of the disk .

所以减速，刹车通过，能量的转换达到了，从，重力势能，转化到旋转圆盘上。
