1
I'm about to experience weightlessness for the first time.
2
Oh my god! Oh my god that is so strange *Oh my god* this is totally freaky this is way better than I expected I'm just gonna say that right now *um* I'm going up to the ceiling and here we are.
3
I am ridiculously excited, because behind me is a Zero-G plane.
4
I'm in France, I was invited here by by the youtuber Bruce.
5
This is Bruce, Diana physics girl.
6
We are going - flying some parabolas- we're going into Zero-G It's gonna be awesome! C'mon The principle behind weightlessness is pretty simple, the plane and everything inside it just need to accelerate towards the earth at the same rate as a freely falling object in a vacuum.
7
That is 9.8 meters per second squared So, you can think of your body as this pen, and the plane as this bottle and when it's freely falling, there's no contact force between the pen and the bottle, and so the pen feels weightless.
8
So you might think the way to do this is just to put the plane into a dive.
9
But that's not actually how it works.
10
Instead, the plane starts climbing at a steadily increasing angle.
11
With no windows inside, it's impossible to tell that this is happening, and all you feel is pressed into the floor with a force 1.8 times your body weight.
12
This is because the plane's acceleration is directed upwards and perpendicular to the floor, and it makes standing very difficult - not only are you nearly twice as heavy, all the blood drains from your head and into your feet - which made me pretty dizzy. -Ah!
13
Haha! So weak... ugh -Lying on your back is much more comfortable, and we're advised not to move our heads around and look straight ahead, because in hyper-G our vestibular system is hypersensitive to movement, which can lead to motion sickness. And that's why this is sometimes called the vomit comet.
14
-I kind of like this. -It is fun, feels like someone lying on you -Yeah -Not like that.
15
Once the plane is climbing at about 50 degrees, the engines are ramped down, and the plane is put into a parabolic trajectory.
16
It's at this point that you start experiencing weightlessness. -I can feel myself getting lighter... oh that is such a strange feeling... that is so weird...
17
-The plane and you are still moving upward, but you are accelerating downward.
18
-There's Diana, she's the physics girl Then the plane peaks, and start speeding up again towards the Earth.
19
The whole time the plane is accelerating toward Earth with the same acceleration as a free falling object in vacuum, the pilots have to very skillfully adjust the thrust to perfectly balance air resistance, and maintain exactly this acceleration.
20
Oh, my goodness- how do you feel?
21
This is incredible.
22
So, it's like throwing this bottle into the air the pen inside experiences weightlessness from the time it leaves my hand, until it comes into contact again.
23
After 22 seconds of weightlessness, the pilots pull out of the dive again, subjecting us to hyper-g...
24
as the plane accelerate upwards.
25
In total, we have performed thirteen of these zero-g parabolas- plus, one martian gravity and two moon gravity parabolas.
26
Okay, we are now in Mars gravity.
27
In Mars gravity i can do one arm pull ups..
28
maybe. I am the martian.
29
We brought along some experiments to do in zero-g.
30
So, this is in about 1g, of gravity this are what the flame looks like on this barbecue lighter now we are gonna try it in hyper-g?
31
And then we'll try it in zero-g and it should be...
32
We will see... (2x).
33
We take it for granted that flames had this distinctive shape.
34
But that only because of gravity.
35
The products of combustion have more energy and so, move around faster and take up more space than the cooler air around them.
36
Therefore, there is a buoyant force on them, which is greater than their weight- and so, hot air rises.
37
This helps pulling the oxygen from around the flame to continue the reaction.
38
We are going through hyper-g.
39
i keep blowing out the candle, because...
40
The, uhhh... stress of hyper-g is significant.
41
In hyper-g, this effect is magnified.
42
Since the effect of gravity is almost twice as much.
43
This amplifies the difference between the weight of the hot air, and the weight of the cooler air around it- and so, the hot air rises faster...
44
making, a longer flame.
45
Oh my goodness.
46
Look at that flame just...
47
in zero-g 'cause there is...
48
much less buoyant force, to carry away...
49
And so, the combustion is not as good you can see a lot of smoke.
50
coming off, of that candle.
51
And it's incredible.
52
So, we still have a gas flow so this is why the flame is not circular.
53
It is not a sphere, but it looks very strange.
54
In zero-g, the hot air is still less dense than the cooler air...
55
but, now there is no weight, and no buoyant force.
56
So, the flame doesn't rise as high.
57
This flame still maintain some if it shape, because of the flow of fuel from the lighter otherwise, the flame would form a sphere.
58
Like on the space station.
59
Where, it's very difficult to maintain the combustion reaction.
60
because it's hard for oxygen to access the fuel with all of the combustion products getting in the way.
61
So, if you're ever unsure about what the gravitational acceleration is where you are.
62
Well, looking at a flame is a pretty good way of finding out.
63
I also brought along a slinky, to try the slow motion slinky drop but, in zero-g.
64
Of course, here i couldn't dangle the slinky under it's own weight so, i swung it around my head instead.
65
The effect, should be similar with each coils stretch to provide the tension that keeps...
66
the length of slinky beyond that...
67
accelerating in uniform circular motion.
68
I wanted to see what happens to the end of the slinky, when i let go.
69
Here we go, 3, 2, 1.
70
Did you catch that?
71
The slinky remain fairly stretch out, and kept rotating at about the same frequency as before.
72
Initially, i thought this was a boring result.
73
But then i realized...
74
the reason the slinky doesn't contract, is because weight, was never part of this equation.
75
The slinky stretched out in the first place, because it was rotating.
76
And, since it's rotating after i let go...
77
roughly, the same amount of tension is required to maintain that circular motion.
78
And so, it doesn't contract.
79
In zero-g, it's possible to have a stretched slinky rotating in place, without contracting as long as the tension in the slinky provides the centripetal force, it will keep spinning.
80
This just goes against my intuition.
81
Which is, made of course...
82
only had of experiences with gravity.
83
Being weightless, was an unforgettable experience.
84
But, maybe my favorite part, was how it challenged my intuition.
85
And that's the reason, we need to do research, in zero-g.
86
I want to say a huge thanks, to the team at NovaSpace who made this an unforgettable experience.
87
And of course, Bruce who runs a french youtube channel, e-penser for inviting me.
88
You should really go check out his video from the zero-g experience, and of course Diana, the Physics Girl.
89
Go check out her video on zero-g here.

연습 팁

이번 비디오를 활용하여 영어 쉐도잉을 실천해보세요. 비디오 속 빠른 말투와 생동감 있는 표현을 따라하는 것은 발음과 억양을 개선하는 데 큰 도움이 됩니다. 다음과 같은 방법으로 연습해보세요:

  • 비디오를 처음에는 전체적으로 보면서 내용을 파악하세요.
  • 그 다음, 섹션별로 여러 번 반복해서 들어보면서 따라해보세요. 각 섹션의 말 속도를 조절하여 자신의 페이스로 따라가는 것이 중요합니다.
  • 말할 때는 목소리를 높이거나 낮추어 감정을 표현해보세요. 이렇게 하면 shadowspeak 연습에 도움이 됩니다.
  • 비디오를 반복적으로 시청하고 연습함으로써, 영어 스피킹에 자신감을 가질 수 있게 됩니다.

유튜브 영어 공부에 이 비디오를 포함시켜, 무중력의 원리에 대한 이해와 동시에 영어 실력을 쌓아가는 재미를 느껴보세요!

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법

쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
