I want a vector that I want to call the 0 vector.

我就需要这样的一个零矢量

So you can guess who the 0 vector is.

大家可以猜想零矢量是什么

耶鲁公开课 - 基础物理课程节选

The 0 vector is a vector of no length.

零矢量是没有模长的矢量

耶鲁公开课 - 基础物理课程节选

So that vector is called a "Null vector."

这种矢量就叫做"零矢量"

耶鲁公开课 - 基础物理课程节选

I cannot show you the 0 vector.

我应该无法表示出零矢量

耶鲁公开课 - 基础物理课程节选

it's clear that you want to add a vector that looks like that, because then you go from the start of this to the finish of that, you end up at the same point and you get this invisible 0 vector.

显然应该给它加上这样一个矢量,因为从这个矢量的起点指向那个矢量的终点,最终指向的是同一个点,你就得到这个不可见的零矢量

It's very clear that if you want to take A and ask, "What should I add to A so I get the null vector?"

显然,你们会拿 A 来问,"拿什么来加矢量 A 可以得到零矢量呢"

耶鲁公开课 - 基础物理课程节选

I expect that if I add -A to A, I should get the guy who plays the role of 0 in this world, which is the vector of no length.

我希望如果用 -A 加上 A,应该得到一个零矢量,也就是一个没有模长的矢量
