Now, let's ask, "Is it true for this force

现在我问 "这个力
that the work done in going from one point to another

从这点到另一个点所做功是不是
depends only on the path,

只取决于路径
or does it depend, I mean, it depends only on the end points

还是取决于我的意思是只取决于端点
or does it depend in detail on how you go from the end points?"

还是取决于它如何到达终点的运动过程"
You all have to understand, before you copy anything down,

在抄下任何东西前你们应该明白
where we are going with this.

我们的目标
What's the game plan? So, let me tell you one more time

我们的打算是什么我再说一遍
because you can copy this all you want,

你可以抄录你想要的
it will get you nowhere.

它什么都不会告诉你
You should feel that you know

你应该明白
where I'm going but the details remain to be shown

我的大方向虽然细节方面还要详讲
