Hey, it's me Destin.

嘿，我是 Destin。

Welcome back to Smarter Every Day.

歡迎回到 Smarter Every Day。

So today we're in the rocket van and I've got two little science helpers here,

今天我們在火箭休旅車裡，我這裡有兩個科學小助手，

right?

對吧？

Yes.

是的。

Are you wearing your seat belts?

你們繫好安全帶了嗎？

Yes, sir.

是的，長官。

Okay,

好的，

we're going to do something pretty interesting.

我們要做一件非常有趣的事情。

Check this out. 片語動詞

看好了。

I've got a pendulum suspended from the top of our family van 文法

我在我們家的休旅車車頂掛了一個鐘擺，

and we're just going to drive forward.

我們現在要向前開。

We're going to accelerate.

我們要加速。

So, if we're going that way,

所以，如果我們往那邊開，

which direction do you think this pendulum should go? 文法

你們覺得這個鐘擺會往哪個方向動？

What do you think?

Which way is it going?

往哪邊動了？

That way.

That's right.

It's because I'm accelerating,

這是因為我在加速，

right?

對吧？

Does that make sense to you guys? 語氣意圖

你們明白這個道理嗎？

Yes, sir.

明白，長官。

Okay, very good.

好的，非常好。

I was hoping it would make sense. 語氣意圖

我就希望你們能明白。

So, we're going to change it up just a little bit. 片語動詞

那麼，我們要稍微改變一下。

Okay,

好的，

so now what I'm going to do is 表達脈絡

現在我要做的是，

I'm going to replace this pendulum with a balloon. 片語搭配

我要把這個鐘擺換成一個氣球。

And we should see the same thing, right?

我們應該會看到同樣的現象，對吧？

Let me cut this off. 片語動詞

我把這個剪掉。

So, what we're going to do is

所以，我們要做的就是，

we're going to accelerate that way.

我們要朝那邊加速。

So, we have the mass of the balloon and the acceleration.

我們有氣球的質量和加速度。

So, that should net in a force and we'll have to react with this string, right?

這樣應該會產生一股力，而我們得用這根線提供反作用力，對吧？

You guys ready?

你們準備好了嗎？

Yes, sir.

準備好了，長官。

go.

走。

There it is.

I brought something to show you.

Remember I told you?

I was going to bring this jar earlier? 文法

So, it's like this.

所以，就像這樣。

Imagine this entire van is just like this jar. 表達脈絡

想像一下整輛車就像這個罐子。

And all the air inside this van

而車裡的所有空氣

is just like the water in the jar.

就像罐子裡的水。

Does that make sense?

明白嗎？

So, let's imagine that the balloon is this bubble on top

所以，讓我們把氣球想像成上面的這個氣泡，

because the helium in the balloon is lighter than air, right?

因為氣球裡的氦氣比空氣輕，對吧？

So, that causes it to do what? 文法

所以那會讓它怎麼做？

Go up.

往上走。

Go up.

往上走。

That's right.

沒錯。

So, if I've got this air that's just like it,

如果我這裡的空氣跟它一樣，

what happens if I move the jar that way?

那如果我把罐子往那邊移動會怎樣？

It did.

動了。

All that water sloshes to the back.

所有的水都晃到了後面。

And when that water sloshes back this way,

當水往後晃的時候，

which direction does the bubble go?

氣泡往哪個方向跑了？

You see that?

看到了嗎？

So, the air bubble moves in the direction of acceleration. 片語搭配

所以，氣泡會朝著加速的方向移動。

Does that make sense?

懂了嗎？

I know you're five,

我知道你才五歲，

but I think you can get this. 用詞

但我覺得你能懂這個。

Okay, so I've got my seat belt on.

好了，我繫好安全帶了。

If I drive forward real fast right now, 用詞

如果我現在很快地向前開，

which direction is the balloon going to go?

氣球會往哪個方向動？

Forward.

前面。

Why will it go forward?

為什麼它會往前？

Because um all the air is sloshing back. 慣用語

因為……所有的空氣都晃到後面去了。

That's right.

沒錯。

Very good.

非常好。

Watch this.

看著。

Look at that.

看看。

You see that?

看到了嗎？

So, you know what that means, 文法

那你知道這意味著什麼，

don't you?

對不對？

Yeah.

嗯。

That means you have more air to breathe than Daddy does 文法

這意味著你有比爸爸更多的空氣可以呼吸，

when I'm going fast.

當我開得很快的時候。

Did you realize that?

你意識到這點了嗎？

No.

沒有。

Yeah,

是的，

then what that means when I go fast

這意味著當我開得快時，

that means more air sloshes back there to you

更多的空氣會晃到你那兒，

and you have more oxygen to breathe.

你就有更多的氧氣可以呼吸。

Doesn't it feel good back there? 語氣意圖

在後面感覺是不是很好？

好了，

so now we have the plumb bob right next to the balloon. 文化背景

So, if I go forward,

那麼，如果我向前開，

they should spread apart, right?

它們應該會分開，對吧？

Let's check it out.

讓我們來看看。

Is it working?

成功了嗎？

成功了嗎？
