当物体从A到，重力做的功为。

B Well, when it goes from a to b, -mgh1 the work done by gravity is minus mgh1.

我只想知道重力，做的功。

I only want to know the work that gravity is doing.

根据这个式子，做的功,因此多数派是正确的。

The pressure is going to decrease along the way, but it's going to have to do more work So the majority in this case is right.

And the idea was that gravity did work on the water and falling, and that work led to the generation of heat.

焦耳的想法是,重力对水，做了功。

It's just minus the sum of all these things, because of course these are just defined as the work done by the environment to the system.

等于负的这些东西的和，因为它们的定义是,环境对系统所做的功。
