One thing I think you guys will really like is the collection vectors.

我想你会矢量图系列。

Well, first of all, you can't use relativistic and nonrelativistic vectors in the same equation.

首先，你就不能把四维矢量和非四维矢量用在同一个等式里。

Right over here that I'm kind of shading in blue.

力矢量也是 它也垂直于地球表面。

Animated videos like mine require hundreds of vectors to check difficult and time-consuming to make.

像我这样的动画视频需要数以百百的矢量图来查制作的难度和耗时。

This is the opposite side to the angle.

蓝色矢量的长度是角的对边。

Let's think about it a little bit.

这个矢量的大小。

We are coming up with newer vector control methods. We are coming up with new drugs.

我正在研究新的矢量控制方法。

Now this is after its traveled a little bit-- its new velocity

现这是 它的新速度矢量。

Now, given that, can we figure out this angle?

这里我 黄色矢量是垂直于斜面的？

And once again, in this video, these are vector quantities.

再强调一遍，这些量是矢量。

But what I said like Storyblocks, you can download beautiful pre-made vectors to use in your videos.

但正如我说的有关 Storyblocks 能提供的，你可以下载好看的预先制作好的矢量图，在你的视频中使用。

Vector quantities also have a magnitude, plus an extra piece of information, direction.

矢量不仅具有大小，还额外包含方向这一信息。

You can either use forces and vectors or you can use energies and scalars.

您既可以使用力和矢量，也可以使用能量和标量。

Imagine that first wave describes the y-component of some rotating vector.

想象第一个波描述了某个旋转矢量的y分量。

So from a screen, literally a bitmap is taken to a scalable vector.

所以从屏幕上看，一个位图实际上是被转换成了可缩放的矢量图。

And so what we could say is let's do a vector addition right here.

所以我可以说，让我在这里进行一次矢量加法。

That is going to be the vector of the velocities.

那将是速度的矢量。

Forces are vectors, and so I have to add them up as vectors.

力是矢量， 所以我必须将它加起来作为矢量。

To add vectors this way, you'd get this vector right here.

要以这种方式添加矢量， 您会在此处获得此矢量。

All forces are  vectors, class that means they have both … ?

所有力都是矢量，这意味着它既有… … ？
