- An astronaut performs a demonstration of centripetal force onboard the International Space Station. I had the opportunity to work with NASA's Teaching from Space office at the Johnson Space Center to author a handful of such lessons, which were recorded on orbit.
I actually thought Centripetal Force was a "product" (for lack of a better word) of gravity. Now I feel silly seeing that.
One interesting product of gravity is that light things go up. It is interesting too think about what happens to "light things" in space (like a helium balloon). I'm glad you liked the video.
Centripetal force is the product of anything that keeps an object from continuing on a straight path. It can be a rope, a container, or yes, gravity.
@@AndrewVandenHeuvel Well actually Andrew, it not a product of gravity that makes light things go up! It’s that things move outwards on straight line paths, that’s the product of a ‘centrifugal’ effect due to inertia. Sorry to burst your tea bag! The liquid in that container is heavier than the air or can be said to have a greater inertia. So, when the bag spins it moves outwards and the bubbles move inwards. But actually there both moving in a straight line motion and it is the container which prevents them from continuing in that direction.
@@cybermonkeys sorry to burst YOUR tea bag but there is no such thing as centrifugal force. What appears to be an outward force is simply a mass obeying Newton’s first law of motion by continuing to travel in a straight line whilst it’s frame of reference is changing direction. This is why you are ‘pushed’ against the car door when going around a corner. The car is changing direction but you are continuing to travel in a straight line.
@@AndrewVandenHeuvel Sorry but what on Earth are you talking about?
This has to be one of the coolest experiments I've seen done in space.
Watch star wars bruh
🇮🇹 It Is still centrifugal force to me! The heavy tea goes towards the bag sides whereas the air bubbles obviously gather to the only place that it is left....
The CENTER❗

Yep, 🏴 And I’d totally agree with you! It’s not the bubbles moving inwards 👇 It’s the tea that’s moving outwards. ☝️That’s what centrifugal means? 😅 So, really this video should be called, ‘Centrifugal Force’ onboard the ISS?
@@wavydaveyparker All of the sudden I GOT It ❗ EUREKA ❗
We on the Earth are like the air bubbles and the tea Is the space...The universe is a kind of container❓
Pherhaps space is really heavier compated to matter❓
Or rather ..has more Energy ❓
Will I have a phisic Nobel ❓
🙏
@@K22channel 🤣 I have no idea what you’re talking about and don’t speak Italian ⁉️ And have nothing to do with the 🇸🇪 Swedish Institute, so can’t offer you a Nobel Prize 💰 But, strangely you did make some sense there! 🤪 What are you growing in that garden of yours? 🌵 I did make a silly little video which you might like to watch ⁉️ though. And I’d like to hear what you think? 🤔 I could do with some support 👍 🙏
@@wavydaveyparker send your video link 👍
@@K22channel It won’t let me drop a link
What if you think of it as the heavier tea being pushed out leaving the lighter air in the middle?
Exactly.
That seems centrifugal force to me.
Sounds easier to me. Same as seeing very large bubbles in slow motion. It almost looks like the _water_ is cascading down the sides of bubble, being pulled down by gravity. It gets to the bottom and 'fills up' the bottom of the bubble like a bottle and more water above the bubble is falling away from top if.
Shows there is a force pulling things to the center of support and rotion because it takes energy to move the air bubbles 🫧 against their rest positions
Gravity is NOT absent on the space station . Everything is falling at the same rate due to gravity pulling everything towards the centre of the Earth.
Correct and the space station also has a huge forward velocity vector and inertia, which keeps it in a ‘free fall’ motion around the earth. Keep this up and I’ll have to put this in your school report.
@@cybermonkeys yeah , you keep telling us your a teacher. Big deal. You are still wrong about centrifugal force.
@@arnesaknussemm2427 yeah, you keep telling us you’re educating us. Big deal. You are still wrong about orbital motion.
@@cybermonkeys Please explain where I am wrong.
@@arnesaknussemm2427 Thanks for asking so politely. And to be honest with you…we are both correct. The space station does have inertia and a forward velocity vector and wants to continue with a straight line motion and it is gravity, which acts as the outside force causing it to fall at the same rate around the earth in an orbit, because it’s being pulled towards the centre of the Earth. The centrifugal and centripetal effects on the space station are balanced.
the technique to make gravity when there is none. amazingly awesome!
Man I would love to go to the space station
at the end of the video he screws up and says "you the LIQUID disperses through out"
There is no bubbles in that bag, it had the same effect like water and oil does when mixed and brought together.
There are two different color liquids in that bag
Even if that were true, the same concept still applies.
"you can see the liquid disperses throughout" is what he says, and he didn't screw up. "throughout" here means what it commonly means and implies nothing about a distribution from center to periphery. The fact that the liquid has the (much) greater volume doesn't prevent it from being the element of dispersion in view.
@@blue_ouija
Well it's not only not true, it's ridiculous. Why would they have a standard, sealed, bag--in this case of water and another (immiscible) fluid--aboard ISS? If it were for this demo, why would it have such a weird shape, instead of say a foot-long tube of water with some kind of oil in it?
It's just a bag of tea; That's how they are packaged for use in the station.
They probably leave a bubble of air in them for a bit of compressibility/give. A margin of safety.
The liquid is a heavy element being put into motion by its fellow liquid material. If you put a few loose drops of liquid in a big container and spun it, i dont think the drops would fall to the edges.
This is not centripetal but centrifugal, isn’t it? The centrifugal force makes everything inside go outwards and since the liquid is heavier, it pushes the air to the centre.
centrifugal force doesn't exist
The air "bubble" was so exactly in the middle of rotation that it looked completely motionless, like when a wingsuit jumper has a camera mounted on a pole to has helmet...the face is always perfectly still, and everything moves around it!
Good job 👍
Amazing this proves gravity is rotation and the outer wall has the most gravity and the center has less gravtiy and the center is where the oxygen goes
One question is if the bubbles in the middle move slower then the liquid on the outside
This would allow us to know if.we can make gravity by making the outside move faster then the center
All of the sudden I GOT It ❗ EUREKA ❗

Can we call centripetal force as negative centrifugal force?
cool
Someone bring a fidget spinner to the ISS, give it a lot of force, and leave it there for days
I have a Doubt,
If you were to rotate a ball with a string attached to it around you, it would slowly moves spiraling downwards,
BUT if you were to do that in the space, the ball will slowly spiral into the center?
Very good question!
Not the laptop mounted to the wall😂
11 year ago.world was so develop
why am I getting this in my recommendations now? good experiment nonetheless
It has a lot to do with the boundary layer of the bag. Liquid is sticky
I am not a phyisit nor apparently know how to spell it. But I have cause to think as to what effect your experiment would show if it were done in a non atmospheric condition such as out side the craft vs inside where there is an atmospher. The bubbles are a gas, the liquid is a solid. Thus I would think it might make a difference when done in an atmospheric enviorment vs an enviroment not having an atmospher.
I reckon my question is, does a artificial vaccume regardless of how good the device is at causing a vaccum, still have an atomospher, because in the vaccum of space there isn't an atmospher.
Like I said, I'm not a phyisit nor do I apparently know how to spell it.
Liquid isn't solid, unless it freezes, which it probably would in space.
The bag would bulge due to the lack of atmospheric pressure, but assuming you can spin it and it's not frozen, the centripetal force of the liquid still pushes the air to the center.
@@RobertEmery If I understand basic physics correctly, bubbles are gas, their neither a solid nor a liquid. In a controlled atmospheric craft. The entire contents including the gas is the same tempature. However, out side it the bag was not moving, would cause one side to be hot while the other was cold. Meaning the bubble on one side would be frozen in place, while the bubble on the hot side wouldn't be. But if the bag is rotating, the hot side and cold side would be constantly changing. How would that effect the bubbles. When the bubble are frozen in place one moment and not the next.
@@wmgthilgen Your initial question was about atmospheric pressure, not temperature.
Whether or not the tea would freeze on one side or both is a different aspect of the experiment altogether.
Also (not trying to be not picky, I understand English may not be your first language)
"they are" = they're
"Their" is possessive, as in "it's their bag of tea."
Cheers!
How u talk in space,when sounds waves can't exist in space
Centripetal Force Onboard the ISS
Someone tell the commander what a torque is (if he knew he would use two fingers to give a pure rotation on the tea instead of having to chase it around. I think)
You're an idiot. He's an astronaut, of course he knows what torque is. Notice at 0:49, he use both hands to set the spin, but inevitably one hand will spin it slightly harder than the other, and later in the video he is trying to correct this by spinning with only one hand, to bring it back into view. He even says so at 1:49.
No reason to. I just got done with the calcuations, and I'm kind of wrong about what I said.
However, if you were in a rotating space station, even a very large one, the force you would experience wouldn't be exactly the same as gravity though. If it was VERY large you probably wouldn't be able to detect the difference easily though.
Try and debunk that one flat Earthers 🤣
haha awesome! I had that theorie from prof. Michio Kaku. maybe you should check it.
Is that tea bubble a disc or a ball?
Not really the same.
If we had rotating space stations to simulate gravity, when you jumped from a chair, you would immediately hit terminal velocity. Jumping from large heights, it would be the linear velocity at which you started at and what the floor is moving at that you would need to contend with.
“Absence of gravity”
Ok. 👏
Fake account.
Watch his watch.
So with enough spin you can create a white hole kappa
interesting. but could you simplify that, Enlish is not my native language...
I was really looking for the waterbubble made to rotate. Wherein air and tealeaves were added, and settled respectively arouynd ther axis of rotation and the surface. Exactly the opposite of what is being taught in all schools in the western world.( For we have an iron core= the heavier material settled where the gas should have settled. Offcourse the iron core theory is pseudo science, and severly supported by all great minds, because i didnt see or hear any of them mention this slight discrepancy.)
but this will do too
Nothing "amazing" about this. It's not magic, people.
Fool.
Hate to say this being a NASA fan. But that looks fake. Computer Generated Imagery.
Yeah yeah, move along fake account.
