A bigger circle also means you wouldn't need to spin it as fast :-D

@@Blackholebirb because the circumference is larger (i gotta explain it to the few that dont understand)

I was thinking about the difference a larger diameter room would make as well. In space you would also end up with 1 G at 90 degrees to the wall not having to mix it in with real gravity on earth. Or just constantly accelerate at 9.8 metres per second per second and there would be no problem. It would take about a year to reach the speed of light. Then start slowing down at the same rate and stand on the ceiling instead. Problem solved I reckon 🤠

Also we can't assume that humans can't adapt to a gravity less than earth's and still remain healthy. Maybe 3/4 earth gravity or half would still be ok. All we really know is that zero gravity is a disaster for the human body over time.

@@onastick2411 Zero gravity is a problem over time for humans but mostly because of muscle mass and bone structure. That's why people on the ISS have to work out often, to keep that mass up. I think a healthy person could do it no problem. The only problem lies in the longevity of it. How long can they last? That's a question to be studied.

Exactly. I went on the same thing. It welt like I was looking upwards but we were really just swimming.

It's called something 3000

Ours was called the Gravitron. I fondly remember one guy who would stand on the wall and even walk towards the centre. Guy who ran it kept a sign with him, "ride has 2 speeds, fast and faster". Good times!

​@@dabbydabbydoo Dreamworld? Dreamworld in Australia used to have the Gravatron ride, though little often called it the Vomitron. I liked it when I was young, it's a pity it's not around. If it were though, current Australian safety bs wouldn't allow you to move around like you could back then 😒

skuzlebut82 from an outside perspective it wouldn’t go in a straight line. From a fixed outside perspective the ball would have a velocity tangent to the path of rotation that the thrower is on.

@@kcwidman When the ball is released, it travels in a straight line from an outside observer. When the ball is released, it travels at a tangent based on the forward speed and the lateral speed at the time of release. If it were to continue curving, it would have to have a continuous force pushing it sideways as it traveled after being released.

@@skuzlebut82 the air is also moving, so it probably will have some effect.

skuzlebut82 your idea would only work if the room is vacuum, so that's not how this particular room works.

@@pheelbanana1646 Vacuum doesn't affect projectile trajectory. Air is only a source of "frictional" force that barely drags the ball. Air and the ball collide, but the momentum is barely affect since the mass of air is so small.

Exactly

Yes I love that one

I rode it 15 times in a row one year. It was fun because all the kids would try to turn upside down while the ride was moving but it spun so fast even lifting your arm was like a 20lb task. Oddly enough I get sea sick and car sick but not gravitron sick.

@@LC-sc3en Right!? I get that too! Whenever I go to the amusement park in my hometown I would always go on the two gravity rides (one of them goes almost vertical) and attempt to move (within safety parameters of course) parts of myself like my arms and legs and head even looking left and right. I would rarely get sick from them yet being on a boat or even an elevator would leave me feeling woozy.

Write I had the same reaction 👍🏽🥸

I dont quite understand the similarity, but I remember this cool trick. I did it with someone holding my arm as I try to move it up

What was the specific reason that they told him not to move his arms/hands at this moment? They never explained what the reason was, as far as I can tell

@@hypnotoad28 Probably minimizing any danger to Tom, as well as (maybe) experimental integrity. They'll have a list of procedures to start/stop this experiment and they didn't want anything unplanned happening in that room during that time. My best guess, at least

@@albpoolshark nope. it's because this is a youtube video. so they wanted him to experience him lifting his arms as instructed so we could see the reaction best.

@@tmass1More likely a combination of those two things. Additionally, they talked a lot about how sick people could get, so they likely wanted to avoid any possible barfing too. Just a whole slew of reasons, really.

there's a glitch in the matrix

AsHalt bbcb

I guess they wanted him to wait for the room to be completely still so Tom could experience the full effect of having to readapt, instead of noticing a partial effect part way through slowing down and ruining the surprise.

It's weird they were serious about that but I wonder how many people turned their head when the tenis ball shot off to the right

Anonlove they’d just get dizzy and throw up. And hopefully not miss their vomit bag.

Would it not bi different if you threw something in the direction it rotates, 90 degrees to it or in the opposite direction? Like if you threw it in the opposite direction with the same speed as rotation it should mor or less just stay in place until air friction getts it moving :P while in the direction of rotation, the added speed would make it fall much faster towards the floor since its to the outside, similar if you go, with or against the rotation ;)

Tbh anyone would. Its just such an interesting and unusual experience most humans have not undergone before.

bro i was wondering if anybody was gonna mention that fair ride. It felt like the whole thing was falling sideways but it was just the gravity shift. It was cool, i was able to stand up as it was rotating, the gravity felt stronger though, it was hard to stand up.

@@John-X that's spaceship 2000. At least if the walls slid up.

It was called "the gravitron" in my area

The Gravitron and I do not get along. The zipper and spinning tea cups also don't like me, I think they're ganging up and it's not fair!

OMG that was my favourite ride, I went on it 10 times maybe more in one day. By the third I was rotating upside down and doing all sorts of weird dance moves while trying to stand

I thought of the Gravitron as well. I've only gone on that ride once and felt quite sick due to whatever force I felt. Made the mistake of having a ponytail behind my back so the entire time I felt like my head was being dragged downwards due to my ponytail being stuck behind me. I wanted to try moving but just couldn't get far for some reason.

YES! The Starship 2000. I remember one of the carnival workers used to walk around in it while it was going. I did not enjoy those wall pads slamming every time they slid when the force changed.

At Great America in Gurnee they used to have the Cajun Cliffhanger back in the day. Same concept except it was open top, looked like a giant old whiskey barrel, no operator inside with you, and you just stood with your back against the wall as they started spinning. Once you were up to speed, the floor dropped out and you were stuck to the wall. It was one of my favorites.

I believe there's some references at experiments where the spin is actually used either to power the "saucer" or to counter gravity from Earth and have the whole thing flying.

@@acmefixer1 woooosh

Just like the running scene in 2001 A Space Odyssey then. In space you'd have no Earth's gravity pulling you down so would be running along the walls. Build a wider ring and the speed difference between your head and feet would be smaller and much more manageable.

*T H E F U T U R E I S N O W*

That’s backwards, but it makes me wonder… With a centrifugal force of 9.81 m a second equivalence, could a person actually run fast enough to suddenly become weightless inside the station?

I get this sensation when standing in the middle of a bendy bus or a bendy subway car.

I walk like that in the wind

Hello my bus driver almost rolled the buss in a traffic circle

Newton's third law: F = -F. If there is a force acting on an object, then there is an equal and opposite force pushing back on the force carrier due to inertia. Hence if centripetal force from the room's wall/floor is pushing you in towards the centre of the room, your mass is exerting an equal and opposite force on the wall/floor away from the centre. Centrifugal force isn't what makes the ball "curve" once it leaves Tom's hand, that's true, but it is what keeps him standing at a weird angle, what keeps you pinned to the wall in a Gravitron ride, what keeps the water in the bucket when you do the over-arm spin thing that science teachers love.

xkcd readers unite! At the specified geolocation to be announced

@@ObjectsInMotion If you're not telling me where it is could you atleast send me the momentum?

1FatLittleMonkey well no because as you just said, the equal and opposite force is what YOU exert ON the wall. That is solely a reaction force and not a centrifugal force. So what keeps you pinned to a graviton is your inertia, because at any instant your velocity is tangential to the circle but then the curved path ‘blocks’ your movement which then alters your direction slightly, and this happens infinitely many times at each infinitesimally small angle. There is no outwards force directed ON the person,. It is the same reason why planets can orbit - velocity would take them tangentially away from the orbit, inwards force of gravity alters their direction. No outwards force on the planet

another method of this is leaning your weight on the back of your wrist against a doorway/wall for ~30 seconds and then relaxing. the same phenomena occurs where your arm will raise up on its own

I've done a similar thing where you stand in a doorway and press your arms outwards against the frame. Try it and see what happens. Give it at least a solid minute while applying pressure to the doorframe. Palms facing you.

@@RotchildFrancoisJr I often feel the same way after being on a trampoline or something, if I lie down I can still feel like I'm bouncing.

I'm confused as to the point of this lab. If you were going to do this in space, there'd be no gravity to compete with, and your acceleration would be in a direction entirely normal to the "wall" - so astronauts could just walk on the wall (outer surface of the ring) and treat that as the floor. If done right, your body wouldn't see any difference compared to earth gravity, no?

We are already spinning on Earth at 1000 miles an hour ~1600 km/hr (for modern better measuring). Then you need to allocate the 1000 km/hr the Earth is moving around our particular Star (the Sun). But then our Milky Way galaxy is spinning at around 2100 km/hr. Although its also traveling at 2.1 million km/hr through space. But since the universe is expanding at 70 kilometers per second, then everything is kinda in perspective to everything else. Einstein's law of motion actually showed us that if you were in a car doing 100, you could throw a ball up and down inside the car and wouldn't move at 100 km/h in the cabin itself for the inside observers point of view. But for observers outside the cabin, the ball definitely made a huge symmetric curve at 100 km/h! Which is really strange the more you think about it, because if you throw the ball out the window it immediately travels really fast at great distance!

@@kimsland999 doesn't matter, everything is relative... to us everything else seems to move but we stay still.

@@iCore7Gaming Maybe children enjoy spinning in circles because they are trying to be in line with the entirety of reality, and that when they stop doing this they have inadvertently adjusted to circular movement, and thus not living in reality any more?

To compensate the opposing momentum of gravity in space-time across our known universe as I have not yet adjusted to to your world of circular nonsense. Seems reasonable :)

Exactly! The main difference is that the ships in The Expanse use constant horizontal acceleration (which requires no adaptation, since it mimics Earth's gravity), and the space stations/asteroids in The Expanse are large enough to minimize the Coriolis effect. Until we achieve either of those, we have to figure out how to deal with much smaller rotating systems, where the Coriolis effect is very pronounced.

If the room rotates fast enough, the ball will return to the thrower. :D

@@sleeptyper Really, you just have to have enough headroom to make it stay in the air for half a rotation - less if you don't have to throw directly towards the center.

@ Problem with just tossing the ball upwards is conservation of energy - the ball has already some rotational momentum that you have to cancel with your throw towards the center.

@@sleeptyper Well, once you let go of the ball it flies straight in the horizontal plane. If the momentum carries the ball away from the center, you didn't throw it towards the center but off to the side from the start. It is only because you are inside the rotating frame that it looks and feels weird when you do stuff. 😉

The ball also demonstrates the Coriolis effect. It basically makes wind going in a straight line seem to curve.
