NARRATOR: Like Yasuhiro Kubo here, going for a Guinness

就像久保康弘一樣，要去喝吉尼斯的酒

He'll be free falling from around 10,000 feet

and attempting to catch up with his parachute

The record is determined by how long he waits before jumping.

記錄是由他在跳之前等待的時間來決定的。

Free falling without a parachute is one of the most

在沒有降落傘的情況下，自由落體是一種最

Do not even consider considering to consider to do it, ever.

不要考慮考慮考慮去做，千萬不要。

Especially when even regular skydivers have their off days.

尤其是當普通跳傘運動員也有休息日的時候。

All right, so how does a skydiver fall fast enough

好吧，那麼跳傘者如何才能快速墜落呢？

Well, to find out, we need to brush up on terminal

好吧，要想知道，我們需要對終端進行刷新

As an object falls, it collides with trillions

當一個物體墜落時，它與數萬億的物體相撞。

of tiny air molecules, resulting in air resistance.

的微小空氣分子，導致空氣阻力。

As the object accelerates, the air resistance acting on it

當物體加速時，作用在它身上的空氣阻力

increases until it matches the force of the object's weight.

增加，直到它與物體重量的力相匹配。

It's now at terminal velocity, the maximum speed

A larger surface area increases air resistance,

較大的表面積會增加空氣阻力。

A smaller surface area decreases air resistance,

較小的表面積會降低空氣阻力。

hits terminal velocity around 120 miles an hour

But for Yasuhiro to catch up with his chute,

那麼，我們的哪位想破紀錄的人？

has remembered how we speed up our terminal velocity?

有沒有想起我們是如何加快終端速度的？

Going upside down and reducing his surface area

decreases air resistance and increases terminal velocity.

降低空氣阻力，提高終端速度。

Trouble is-- oh, whoa, it's very hard to control.

問題是... ... 哦，哇，這是很難控制的。

Yasuhiro needed to steer himself into position to grab it.

安廣需要引導自己的位置來搶奪。

Well, skydivers can also use air resistance to maneuver.

好吧，跳傘運動員也可以利用空氣阻力來進行操控。

For example, by adjusting his body shape,

比如說，通過調整自己的體型。

this guy deflects flex more air backwards,

這傢伙把撓曲更多的空氣向後偏移。

Somehow, all of our high flyers were fine,

不知道為什麼，我們所有的高飛都沒事。

but I think we should leave the record to Yasuhiro.

但我覺得我們應該把記錄留給安廣。
