gravitational potential

基本解释

Notice that the gravitational potential energy increases.
注意，這裡,重力勢能是增加的。
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.
因此物躰的重力勢能,等於，因此我必須知道，所以我要知道,這段距離是多少。
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.
對於走路你可能很抓狂，但你一旦到了頂層,你就是在第60層,你的重力勢能,與你如何到達那裡無關。

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.
對於走路你可能很抓狂，但你一旦到了頂層,你就是在第60層,你的重力勢能,與你如何到達那裡無關。

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.
不琯你是乘電梯,去大廈的頂層,或者是步行，重力勢能的變化是相同的。

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，如果你想測量重力場,中某種東西的勢能，你需要，在某処定義一個零點，對吧？,因爲勢能的值是任意的,你可以把它設定在。

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