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。

Mhy You see? Mgy is gravitational potential energy.

你们看，是重力势能。

youdao

Notice that the gravitational potential energy increases.

注意，这里，重力势能是增加的。

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.
