gravitational potential

基本解释

Notice that the gravitational potential energy increases.
注意，这里,重力势能是增加的。
And so the gravitational potential mgy energy of this object is its own mg y, y so I have to know what this y is, and therefore I have to know what this distance is.
因此物体的重力势能,等于，因此我必须知道，所以我要知道,这段距离是多少。
You might be winded doing it the second way, but when you get to the top and you are at the 60th story your gravitational potential is independent of how you got there.
对于走路你可能很抓狂，但你一旦到了顶层,你就是在第60层,你的重力势能,与你如何到达那里无关。

You might be winded doing it the second way, but when you get to the top and you are at the 60th story your gravitational potential is independent of how you got there.
对于走路你可能很抓狂，但你一旦到了顶层,你就是在第60层,你的重力势能,与你如何到达那里无关。

Whether you take the elevator to the top of the Hancock Tower or whether you walk up the stairs, the change in gravitational potential is identical.
不管你是乘电梯,去大厦的顶层,或者是步行，重力势能的变化是相同的。

You know, if you want to measure the potential energy of something in a gravitational field, you have to define the zero somewhere, right, because it's arbitrary. You can set it anywhere you want. It's the same with enthalpy.
你知道，如果你想测量重力场,中某种东西的势能，你需要，在某处定义一个零点，对吧？,因为势能的值是任意的,你可以把它设定在。

In this case you store electricity as the potential gravitational energy in the weight of water.
