I feel like some fair/flat rides definitely exceed these limits. Huss top spins and some frisbee rides are insane, and don’t get me started on the other spinning rides
I think even certain things outside of a theme park can exceed those limits. Slamming the break on a car or like being spun around on one those circular things at playgrounds can exceed g-forces on coasters
@@kiwikiwi2483 Those cases that you mentioned usually don't exceed roller coaster forces. Car braking is limited by the tires, which have a coefficient of friction of about 1 in most cases. You won't get much more than 1 g unless you have downforce (F1 cars can achieve greater than 5 g, I think). A small 2m diameter playground carousel has to be spun at 16 km/h to produce 2 g at the edge. Most kids can't do that, let alone run that fast.
@@Trancefreak12it’s a rare case, but i’ve seen people using motorbike wheels to get roundabouts to insane speeds and the people riding it weren’t harmed by the g force
Tbh, the most nauseous i've ever been on rollercoasters is due to the braking at the end just before the station, some coasters arrive way too fast and have to brake way too hard. For instance, the RMC coaster in Energylandia in Poland is incredible, but I've felt more sick afterwards due to the rapid deceleration.... Thanks for the awesome video!
Its uh crazy you say that cause the only 2 times I have thrown up was after the ride after the coaster stopped. It was pretty embarrassing, it was in florida the ride was a newer one so it was intense but didn't make me sick I enjoyed it quite alot, but then come the breaks and the lightheadedness. It makes us sit there in the heat for a minute or two while I can feel myself about to throw up. Unfortunately it pulled up and right in front of everyone I got to throw up on myself.....embarrassing af.
Was there today and yesterday, definitley not the most intense ride. Silver star is way more fun because you get a lot of airtime. Blue fire's best Part is the roll in the end.
COASTER BOT and CoasterStats, thank you both for this excellent presentation, and for elaborating on the physics, motion and measurement details involved in designing these creations. As a diehard coaster enthusiast, this next-level information is Golden!
Thanks for watching and for the kind words about the video! We're always trying to find topics that even enthusiasts might not know much about. I learnt loads from the CoasterStats team while making this video!
Great video, really puts racing car accidents in perspective. Kenny Bräck crashed in indy car and experienced 214 Gs, totally insane when you think about what you can feel in a coaster with just couple of Gs.
This makes me wonder what kind of insane designs could be achieved if everyone was a fighter pilot. You can use this ride but first you've got to learn the Hick Maneuver and wear this flight suit so you don't pass out.
thank you for telling me about the hick maneuver, that's super interesting to everyone else: you basically tense every muscle in your body below the neck. this restricts blood flow to those areas so the blood in your head won't rush down to your feet as easily. it actually works!
I love how you also included many coasters from different parts of the world. I live in the NL and I recognised at least 4 coasters you put in there. Great job!
Nah, great forces that are even painful are not my taste. For me it's creative and highly flexible layouts, that make you feel flexible and free, soaring through the air. If you make me feel like flying and essentially, like a circus artist, at the same time, you have done it. Especially negative and lateral Gs are my type. I love airtime twists, inversions, unusual angles and a quick loss of orientation and generally a fast pacing.
And even with all that testing, certain coaster brands are nutorious for being uncomfortable. And sometimes one just can't smooth things out enough due to limited building space. The travelling coaster Olympia Looping and Jetline in Stockholm are examples of that.
CoasterStats is an awesome resource, more people should definitely know about them! Also, they reached out to me and I was super excited to make a video with them!
My favourite science teacher is back at it! YES! All those G-Force shifts illustrate bluntly the difference between centre of gravity and centre of mass. Centre of mass never moves, but anyone on one of these coaster trains is dealing with a constant shift of their centre of gravity. Centre of mass is crucial for balancing, and centre of gravity is crucial for dealing with wear and tear.
Absolutely love this, but just a heads-up, the American Society for Testing and Materials underwent a rebrand. It is now ASTM International, and ASTM doesn't stand for anything anymore. They are working on large harmonization efforts with the EN and ISO standards. This is all to broaden the international appeal of using ASTM International standards. It is the F24 Committee's job to manage the standards pertaining to Amusement Rides and Devices.
I remember when I was like 8, I rode a tall drop coaster, and I remember my feet hurting a lot when I was walking off. I wasn’t hit by anything, and didn’t gray out, so why would my feet hurt? The pain only lasted for a few seconds, though.
And this is why I hate the final brakes at nearly every coaster (especially Black Mamba in Phantasialand). But this is a low price to pay for the excitement beforehand. :D
@@coasterbot I have a heart condition. I really shouldn't ride them. I haven't riden one in years now because of it. At first I never knew what was happening. I would get on the ride and I wouldn't remember anything.
You're right: I'm not a fighter pilot. But Riding elite coasters is expensive. I just wanna get my money's worth. But from what I've experience having ridden over 133 roller coasters, the combination of intensity and duration of positive Gs I experienced on Raptor at Cedar Point provides the roller coaster experienced more likely to cause me to grey out than any coaster I've ridden before or after it. It's happened on other coasters, but no one near as consistently as Raptor. I saw stars coming into the break run every other time I rode it, and that was over four years ago when I was only 48 years old. Having said that: I'm more of a negative G guy which is why I prefer Steel Vengeance and Behemoth, El Toro, Ghostrider, The Cyclone at Coney Island at Luna Beach Brooklyn NYC as well as "forceless" Millennium Force to Raptor. But I still LOVE raptor for its extreme positive G greyout intensity. It has the biggest Prime ride time duration of any B&M invert with over 3.700' of track, yet with only a 118' drop. It's cloned by Le Mostre in France that got moved from Japan. Also: the lack of difference between the front and back of a train doesn't merely depend on its length unless there are many cars. (A 4 row 1 car train will have no different experience between each row, but a 6 row 6 car train will have 6 different experiences between each row.). But generally speaking you're correct: the longer the train the bigger the difference between the front and back will be. It's a shame you have to remind people of what is true in 2022, but your truth to physics (especially in the form of roller coaster enthusiasm) is why why I love your channel. I only hope I can finally learn how to enter into your "best roller coasters you've ridden" thing which I had difficulty figuring out last year, so I gave up without entering any data. Since then I've ridden El Toro, Max Force, Goliath at SFGA, Nitro, Raging Bull and The Cyclone at Coney Island in Brooklyn NYC amongst at least 30 others. This is your project: it'd behove you to help me figure out how to participate. I want to, but I cannot if I don't know how to, and there's no shame in that, but If I cannot figure that out: does that mean my opinions don't count? How do you consider the opinions of people like that when you know there are many and want to know their opinion? Thanks for this awesome video about the physics of roller coaster forces on the human body and it's limits. I could never hate this channel even if I don't figure out how to participate in your annual Best coasters list. But if my roller coster opinions don't count: why should any one else's? Thats just a natural response for anyone who loves your channel. If you were in my position: you just might feel the same way too. But please consider I wouldn't feel that way if I wasn't experienced and passionate enough about roller coasters to want to participate in your best coasters list; I hope I can do that, but I cannot promise to participate in anything I don't even know how to participate in, at least not yet. Then again: I wasn't born a classical violinist either, and yet: I am now. I guess we all have different strengths in different places, but in the meantime: we both love roller coasters. Peace, Love, Happy Winter Solstice; Hanukkah, Christmas etc. and thanks or this wonderful video. Much love, Harry!
Curious if you've been on I305? I've ridden quite a bit of coaster as well, probably around the 130 mark too and I305 was unlike anything. I've only ridden it twice, years apart both time. I legit almost blacked out and had horrendous chest pain during the ride. I will never ride it again. For some reason, my body can't take it. I've never experienced that on ANY other ride!
@@nikkisavo7293 I haven't ridden I-305 but I don't doubt your experience, As I said: Raptor is the most intense coaster I'VE RIDDEN due to its positive G forces and its prime ride time duration the latter of which is the most for a B&M invert since it has such a track length of 3,790' (1,155.5 M) but only a 119' (36 M) drop. Thanks for asking though!
one of the main things that I'm scared of on rollercoasters is G-force and blackouts (also inversions) but which would you say is that best at Thorpe park because I'm going on 6th June.
I believed this until RMC came around and completely broke the mold on coaster design. Yes Gforce is a limit but it can be mitigated with angles and speed. We haven’t seen anything yet when it comes to coasters, the best is yet to come.
@@coasterbot Apart from the straight forces (g's) there are also the 6 moments (around the same 3 axis). Moments are the acceleration for rotating around the axis This is most notable on rides that have quick transitions between banking left and right. But this can also be found on the y axis on quick small bunny hops f.e. Spinning rides are also famous for using these moments in their ride experience and some new coasters like ride to happiness are going even further with it.
Hi, I was wondering if you knew if it was ok for a roller coaster to reach a maximum G force of 6.091, thus exceeding 6G's by 0.091for 0.5371 seconds, and reaching a maximum negative G-force of -2.029, thus exceeding -2G's by 0.029 for 0.1629 seconds. I have created a roller coaster design, but is it still considered safe if its slightly over?
Theres this "raketti" (rocket) in linnanmäki Helsinki that launches you at 4 g, then slows you down and drops down again. Apparently it's slowing down with gravity only, but i almost lose consciousness at the top when the blood rushes to my head. Still enjoy it tho. And the losses bit if seat belt swings up, showing that it's actively braking and not just falling back down. It doesn't say how many negative GS on the website, but i wanna know.
i often joke with my friends that every roller coaster is too boring for me, and i need to go on a fighter jet to be able to feel something. hopefully one day i can enjoy something with enough Gs to make me feel ticklish in the stomach again lmao
I had my first real big greyout this summer. It actually made the experience a lot funnier because there I was, hanging 60m above ground, not knowing how the hell I got here, but screaming my poor lungs out nonetheless. Needless to say, I rode again.
If ASTM standards are binding, how are old Schwarzkopfs that pull more than 6 Gs (Mindbender at Edmonton, the upcoming Drier Looping relocation to Indiana Beach, the relocated Laser Loops at Lagoon) able to operate? Thriller pulled 6.7 Gs when it operated at Astroworld, blowing these limits out of the water, but the park was allowed to operate it. EDIT: Got further to the "you can do anything for 0.2 seconds" bit, which might explain it.
It also might depend on how long these standards exist. Some rides may have been constructed before the standards have been created. But we‘re not too sure about the history of those standards.
@@CoasterStats That would explain Mindbender and maybe Thriller/Texas Tornado, but the Laser Loops relocation was recent, and the Drier Looping relocation is still in-progress. ASTM standards definitely apply to rides that used to be grandfathered but then get relocated -- back when Astroworld closed, Six Flags was looking at relocating Texas Cyclone to Fiesta Texas, but couldn't because the clearances didn't meet the current ASTM code (wasn't an issue when it was at Astroworld, because it was a much older ride, and thus was grandfathered in).
Is it taken into account that I'm not looking to be 'comfortable' when riding a thrill coaster? I want a raw visceral, scary experience. As long as it's not going to actually kill me, load me with all those snappy Gs baby. I bet the bottom of Grand National's first double down hits over 6G for a split second, I love it. Night ride, wet rails, good luck spine!
Theoretically, can't you counteract extreme G-forces with opposite G-forces? For example, could you pull a full second of -1.8 gees by bookending it with powerful positives?
No, this isn't a video game lol. If you make someone experience 10 G of force for a second and then - 10 G of force afterwards for a second that isn't the same as experiencing 0 G or 1 G, it would mess you up
Only if they happen simultaneously. Going from one extreme to the other just means an even _more_ extreme jolt (change in acceleration over time, also called "jerk"), which is just as important as acceleration.
@@angeldude101 Well, yeah. I'm more referring to the strategy of interspersing heavy positives with ejector airtime to bring blood more quickly back to the head, and was wondering if one could produce a singular moment of insane sustained ejector by inverting that trick.
Fighter pilots are wearing special suits designed to aid blood flow in high-G maneuvers in addition to their physical training. I seriously doubt that a fighter pilot could walk away unharmed from a coaster that pulled the same G forces as a fighter jet.
I’ve been stuck on a farm my whole weekend in a tent where I’ve spilt coffee, burnt myself in a radiator and got mud everywhere. I keep hitting my head at the top of it. Can you help me?
I think I need therapy because I frowned when I heard intamen reduced intensity of the turn. I want to experience greying out. Redding out maybe not but grey or black I'm fine with.
ugh.... how short sighted.... the humans are the challenge, not the limit! It's all about stimulating he human body, not g forcing it to destruction lol
You're 100% right, and we discuss that in the video. The title is there to grab your attention and comment on the idea of g-force limits being in place, to make you think about what a roller coaster without these limits might look like. As you said, the best roller coasters cater to a wide range of people and are designed to be as enjoyable as possible!
