COASTER BOT Thanks!

[@coasterbot]

Every 2 weeks Gamer_Boy! :)

[@soulsealsaul5553]

So, when will you be a narrator in a documentary, because that narration👌

[@coasterbot]

ha ha that'd be pretty cool! ;)

[@-TheSmoothCriminal-]

Harry, I watched the video and I noticed you forgot about a few kinds of forces, Millennium force, Red force, Gale force, Steel force, and Expedition GeForce all deliver unique forces you cannot experience anywhere else, Otherwise, great job!

[@coasterbot]

You got me ;) Thanks

[@bluetoothenjoyer]

CoastRth I'm literally on the floor dying

[@Maverick-iz1go]

You forgot CoasterForce

[@sportsygirl8]

I haven't been on any of those roller coasters except for Galeforce...very interesting coaster to say the least. I enjoyed it, but it wasn't worth the ticket amount also way too short of a ride.

[@adrenalineaddiction6253]

Lol and roller coaster force

[@jamesliu7970]

The depiction of greying out during the i305 footage is quite spot on, I love it!

[@coasterbot]

Thanks! :)

[@ryanstrembicki5234]

Lol, starts talking about graying and blacking out and immediately shows footage of I-305.

[@coasterbot]

It would be rude not to! ;)

[@sportsygirl8]

I was thinking the same thing. Seems like it's the most popular coaster for people to gray or black out on. I didn't ride it when I was at Kings Dominion because I was afraid I'd black out + anxiety attack following the black out like I did when I rode Storm Runner a few years back.

[@adrenalineaddiction6253]

I love the feeling of graying out 😂

[@alteregocarson]

Amazing video that makes these somewhat nebulous concepts easily understandable. Just came back from six flags great adventure yesterday, pushed some personal limits, and had an awesome time with friends. Thank you!

[@Rebecca-iy4lc]

I'm glad I found this series, your explanation style is easy to understand and eye opening for someone trying to overcome their coaster fear. Thank you

[@coasterbot]

No problem, thank you for watching. I'm glad these help :)

[@amyburkum7602]

Watching this before i ride Hulk in November or December. It truly helps, thank you

[@some1calledalex454]

One of the most interesting and informative videos you’ve ever made, very niceee!

[@coasterbot]

Thank you, that's great to hear! :)

[@808CoasterLife]

Thank you for explaining how someone greys out! I always wondered what happens if you grey out.

[@tismejaytee]

Your vision basically becomes super blurry and you feel like you’ve passed out

[@RT42069]

What about Millenium forces?

[@thatsincredible1588]

I am doing an assignment on roller coaster forces and this was quite helpful. Thanks.

[@clxxiii]

Beautiful video Harry, making the GP educated one video at a time

[@coasterbot]

Thank you :)

[@rollercoasterfreak8349]

This is one of the best videos you have ever made. Great job, dude!

[@coasterbot]

Thank you, it really means a lot! :)

[@iamaloser666]

I love your videos! Y’all make me feel smart because I know a lot of this stuff. Great job!

[@coasterbot]

That's awesome to hear, thanks for watching :)

[@EverythingWill]

Harry Nye the science guy

[@rosiemeade7612]

Ur voice is so calming. I could listen to this all day

[@coasterbot]

Thank you very much! :)

[@KetoOrkyy]

This video honestly explains more about g-forces than other videos about the subject. Great video!

[@coasterbot]

Thank you! :)

[@danielworleyyy]

I could listen to one of your videos even if it was an hour long. Such awesome content and great narration!

[@coasterbot]

Thank you, it means a lot! If you like my stuff, I suggest listening to our podcast - Coaster Bot Rambles. You can learn more about it here: coasterbot.com/podcast

[@joetyler5816]

Best video so far, keep it up!

[@coasterbot]

Thank you, I will do! ;)

[@luc6284]

This is exactly the type of video I was waiting for. Thanks again for this quality content Harry :D

[@coasterbot]

No problem, thanks for watching! :)

[@tobemusic4987]

This must be your best video!! Big up, even if I knew how forces act now it’s all more clear to me and I finally comprehend the concept of greying or blacking out that was difficult to me as I’m Italian

[@coasterbot]

Thank you! I'm glad you enjoyed it :)

[@irishmusiclover100]

These are all the things I love about rollercoasters! The different gforces give me the exhilaration that I always enjoy! I even grayed out every time I rode Intimidator 305 around the first turn. That’s how awesome the coaster is! Thanks for this awesome video about my favorite thing about coasters! 🎢🎢

[@coasterbot]

No problem, thanks for watching! :)

[@sportsygirl8]

Great job and that was a lot of information to be obtained. Did your research well I might add. The one thing that I don't understand is that the lateral g forces are the ones that can cause you to gray out or black out and I rode Storm Runner back in 2012 and I blacked out on it during the launch and regained consciousness towards the end of the ride. There were no lateral g forces during the launch...I have thought that maybe it happened because I was nervous and dehydrated at the time I was on the ride. I rode it again 2 months ago and did not black out at all.

[@coasterbot]

On roller coasters, it's usually positive vertical g-forces that cause you to black out. These are the ones which push you down into your seat. However, being nervous and dehydrated will make blacking out much easier.

[@sportsygirl8]

That is the conclusion that I came up with after thinking about it that it had to have been due to dehydration and nerves because 2 months ago I didn't black out and made sure I was hydrated and wasn't nervous.

[@bariton3779]

Nothing like waking up to a brand new COASTER BOT video ;)

[@TheCodeMaster]

Great video Harry!

[@coasterbot]

Thanks Patrick! :)

[@vinegorre]

My physics teacher decided to have us design a rollercoaster as part of our final exam, so I've been binging these for over an hour

[@coasterbot]

That's an awesome assignment!

[@Klombo114]

I would love an assignment like that!

[@makariarhodes3000]

Very thorough, very informative. Well done again, Harry! 👍🏻😊

[@coasterbot]

Thanks Makaria! :)

[@noshairhassan3769]

why is your voice so satisfying to listen to???😂

[@DomWPC]

Harry can only be described as art in its purest form

[@coasterbot]

Too kind both of you ;)

[@9000knobs]

Awesome ! I was waiting for a episode on G forces and their function. Superb ! Thanks.

[@coasterbot]

No problem, thanks for watching :)

[@tim5084]

Love your vids man.

[@coasterbot]

Thank you! :)

[@dexty112]

Great vid harry! I hadn’t realised laterals were sideways forces.

[@coasterbot]

Thanks! I'm glad you learnt something :)

[@willkeene661]

The airtime hill after I305's first turn is perfectly placed. It's good for getting all the blood back to your brain.

[@moduzit3021]

I know im supposed to be learning but watching this makes me want to be on a roller coaster

[@coasterbot]

I want to be on a roller coaster too!

[@coasterfootage]

@@coasterbotwe all do

[@SeanFlaharty]

Great video once again!

[@coasterbot]

Thanks Sean! :)

[@adrenalineaddiction6253]

For real tho this is my favorite video by great job now I can show this to people so they understand forces thank you and loved how you where in the video riding icon at black pool pleasure beach

[@tigor1]

Always cool seeing your home park in videos, looking at you Mako.

[@chriskarantonis6845]

0:51 the rollercoaster is storm runner at hersheypark. I live in the same town as this place lol

[@coasterbot]

That's awesome!

[@natalieawadalla4368]

amazing video harry!

[@a_cowwithlegs]

There is this one turn on Ghostrider that is super long and barely banked and it packs some hella crazy laterals.

[@gamma1637]

Nice vid! I learned a lot of new things!😁

[@coasterbot]

Thanks, and that's great to hear! :)

[@GD_Coaster]

Great video! But I think what you describe as positive and negative forces, actually are vertical forces. All three types (lateral, vertical and linear) can have positive and negative forces: Positive linear: launches / Negative linear: Brakes Positive vertical: valleies / Negative vertical: Airtime Positive / Negative lateral: to the right / left Well I'm not a physics student, but that makes sense for me and that's what I've heared so far :D

[@coasterbot]

Positive and Negative forces are under the umbrella of vertical g-forces yes, and I forgot to mention this. However, lateral and linear g-forces affect the human body the same regardless of direction. This is not true of vertical g-forces. The amount of force the body can with stand changes drastically between positive vertical and negative vertical forces, hence the further classification. This cannot be said about the other 2 force groups. Nevertheless, thank you :)

[@GD_Coaster]

OK thank you for your explanation! :D

[@Stevenspielburger]

Great video. Really interesting.

[@coasterbot]

Thank you, I'm glad you liked it! :)

[@mckaylathecoasterenthusias6998]

You deserve way more subscribers, and way more likes, your the best coaster bot! Thanks for your quality content and entertainment!🙂👌

[@coasterbot]

Thanks my dude that really means a lot! Thanks for the support :)

[@amandah.9429]

What a great video! You’re editing skills are amazing and you videos are very informative.

[@coasterbot]

Thank you, you're too kind :)

[@OzzyBen07]

When I was at Cedar Point I started to grey out on Millennium Force after that huge drop. It was an interesting experience...

[@coasterbot]

It sounds it! :)

[@rcb3000]

You never fail. I love your videos.

[@coasterbot]

You are too kind, thanks! :)

[@sabrinavierra]

Love your videos! ❤️

[@coasterbot]

Thank you! :)

[@comctrevor864]

This channel is so underrated

[@coasterbot]

Thank you, that means a lot :)

[@madelinegarber7860]

You forgot about inertia. That’s why you get slammed into your seat when you slow down or speed up. Itz’s similar to linear g forces I think. I also haven’t taken physics in a while so I could be wrong. Also thank you for finally explaining the different types of airtime! I keep hearing floater and ejector and never knew the difference.

[@coasterbot]

Inertia is essentially the reason you 'move' in your seat as a result of the respective forces. It's a component of the process in all directions. I should have mentioned it briefly but completely forgot, sorry! I'm glad you learnt something too :)

[@bearky]

Great video as always, very well explained

[@coasterbot]

Thank you! :)

[@damocoaster8451]

Your editing is perfect! (Like you don't know already lol)

[@coasterbot]

You are way too kind ;)

[@damocoaster8451]

You should've posted this video on the 4th of May.

[@E1evenGaming]

i have to do homework on this :/

[@therealone3986]

Lucky

[@wlyjesse]

Great video, and great explanation i know this is a short and sweet comment but honestly great job explaining the g's.

[@coasterbot]

Thanks for the kind words :)

[@drewblouch8625]

Awesome Video!

[@coasterbot]

Thanks! :)

[@drewblouch8625]

COASTER BOT Your Welcome!

[@TropicalHaven]

This is so cool!

[@raviormetal1653]

Nice video! I guess some of the clips where made during your trip through europe? I think i've seen the parks Tippsdrill, Heide Park and Hansa Park in there.

[@coasterbot]

Thank you, and that's very true. I think Heide Park, Hansa Park and Walibi Holland were all featured :)

[@ThemeParkVex]

Great video!! very educational!

[@coasterbot]

Thanks! :)

[@Tuppoo94]

2:15 If we start splitting hairs, essentially all g-forces are caused by a change in speed. The direction of force is determined by the direction in which the speed changes. For example, let's say that a Wild Mouse train moves towards a sharp U-turn at 20 KPH. As the train turns around, its speed along its original direction of motion on the horizontal x plane is reduced to zero, and then goes to negative. We feel the change in speed along the original direction of motion as lateral g-forces as the train goes around the turn. The same applies to airtime hills, there the train's speed on the vertical y plane is turned around, and we feel it as airtime.

[@coasterbot]

If we're splitting hairs even more the g-forces are caused by a change in velocity, as the change of speed in a certain direction is what causes the accelerational forces. Speed doesn't always have to change for acceleration to occur, as you said. A change in direction, even when the speed is maintained, requires an acceleration :)

[@gdteabag3493]

Wow this video quality is over the top! how long on average does is take you to make a video??

[@coasterbot]

Thanks! My videos take quite a while to produce. I made a video about the whole process and how long it roughly takes. You can watch it here: kzbin.info/www/bejne/gKDNpKpvort2bac

[@mollsterw2847]

When a rollercoaster video explains physics better than school

[@terryroberts5309]

Great video thanks

[@chorokee]

I had a gray out in T Express in the part at 100km-paced helix. It was awful at first but fun.

[@darkpineapple2855]

Could you please do a collosus: explained video? Been stuck on it twice

[@coasterbot]

I'll note that down, thanks for the suggestion :)

[@darkpineapple2855]

COASTER BOT wow, a KZbinr who can use the reply button. I dropped a sub ❤

[@olakolade6656]

negative g foce hurts so much! and I like rollercoasters, everything except for that horrible painful sensation the negative g force does to my stomach. I wish negative g force didn't hurt so I could ride many rollercoasters :(

[@PaddletailPhilly]

I love the informational and educational angle of these videos! It's loads of fun for me to learn about the many roller coasters available in the world, as well as what makes them thrilling~ You guys thinking about doing a video on Universal Orlando's Hollywood Rip Ride Rockit?

[@coasterbot]

I'm glad you enjoy them, thanks for watching! I'll note Rip Ride Rockit down for a potential future video :)

[@TheBlackMist]

Very informative video!

[@coasterbot]

Thank you!

[@wypmangames]

the lineair gforce being increase or decrease is also known as momentum where the person or object in the train or a car goes forward while the train or car itsself doesnt go forward (wich can cause accidents if no seatbelts are worn)

[@coasterbot]

Momentum plays a part within all of the force types, this is very true :)

[@bwhugul]

At 6:43 the sentence should be corrected. 'Comfortable' will be contested by anyone who finds the 'stomach drop' wierd or even painful.

[@glory6507]

my man is still hearting and commenting. nice vid btw :)

[@TheMasterfulcreator]

Any reason why launched g-forces (linear ones) feel more intense than positive g-forces experienced on banked turns? For example most roller coaster launches are usually only around 1.4 g's but they always feel intense. However many roller coasters such as millennium force supposedly produce nearly 5 g's on the turns, however I never remember an intense feeling during the turns.

[@coasterbot]

The human body can withstand some g-force types better than others. For example, are bodies are pretty good at withstanding positive vertical g-forces, the one's which many rides reference their high g-force number about. Other types we aren't very good at withstanding. That's what you are experiencing here :)

[@zacharygiles2984]

Are bodies pretty good at withstanding positive vertical g-forces?

[@musshousheh3396]

All gigas have 4.5 gs

[@ryandiepstraten4323]

Very informative!

[@coasterbot]

Thanks! :)

[@IamTalathia]

My lizard brain always freaks out on negative g-forces on hills. I wish it didn't because I'd probably enjoy the ride more. I'm left clinging and gabbing onto something on the verge of primal panic thinking I'm gonna 'fly out' of the ride. Even though I know logically while getting on it that that can't happen. Any recommendations how to stop my brain from doing this? I think if I got on Hershey parks Comet or Wild Cat 10 times in a row lizard brain might... figure it out.

[@coasterbot]

I think we've all done that on at least one ride. The more you ride roller coasters like this the more you get used to that sensation, as you said! :)

[@dripflack6621]

Most intense coaster ive ever been on is Shockwave at SFOT. craziest expierence I have ever had.

[@wonderdogbenji5704]

Were you at Kings Dominion w/ Taylor on July 11? I think I saw you two get on Flight of Fear after getting off Intimidator 305. (edit) Also your visualization of the grey out on Intimidator 305 is really accurate.

[@coasterbot]

I wasn't I'm afraid, but I'm glad you like the grey out scene in the video :)

[@user-cg6ih8mj9i]

Cool video bro 👍

[@coasterbot]

Thank you :)

[@topherd1011]

If you have trouble with blackouts or grey outs on rides, simply squeeze/flex your calves and quadricep muscles in your legs as tight as you possibly can during the more intense moments of the ride- this forces the blood back towards the head …it will solve your issues!

[@macaroni7]

Thank you I’m doin this for a project.

[@coasterbot]

No problem, best of luck! :)

[@macaroni7]

Thanks I’m presenting to my whole class and I’m a bit nervous cuz there all GP. ;(

[@hart4bbq]

Hey man i just came back from Mirabilandia Italy . They have 2 great coasters Ispeed launched coaster from Intamin and Katun Europes biggest inverted coaster from B&M. Maybe a video idea for your channel. These coasters are extreme fast

[@coasterbot]

That's awesome, I'm glad you enjoyed the visit! I'll note those 2 down :)

[@Stephenp503]

High positive g forces can be really annoying like on poltergeist an Six Flags Fiesta Texas. I wanna see the track ahead of me and enjoy the view of being in a bunch of twisted metal, but no! Instead, can only see a bit in the middle where everything else is dark gray or black. :

[@coasterbot]

I see what you mean, sometimes it can be uncomfortable.

[@The444traveler]

Wonderfully explained and educational!!! I AM A STRONG NEGATIVE G JUNKIE!!! EJECTOR AIRTIME ALL DAY!!! From the back seat of course! 😄

[@Zvizdic101]

Samziessss

[@Coastephoto]

goooood video man!

[@coasterbot]

Thank you! :)

[@idk4772]

I'd recommend timed breathing similar to what fighter jet pilots do it helps you with the g forces

[@brycefourn2001]

Great video! :)

[@coasterbot]

Thanks! :)

[@OCEpic]

Great scientific video harry!

[@coasterbot]

Thank you! :)

[@AuraKnight8]

4:07 the strongest ⏬️positive G force I’ve experienced was from wild eagle at Dollywood and the most ⏫️negative G force I felt was from Goliath at Six flags over Georgia. Sometimes I don’t feel a thing like on the Incredible Hulk at universal and Twisted cyclone at Six Flags over Georgia. 🔀 Hell sometimes I feel both like with the Tennessee tornado at Dollywood ↕️

[@dexty112]

Hey Harry. I'm planning on making a vlog/compilation of clips I got from Thorpe park. What music would you recommend?

[@coasterbot]

I'm not sure, I usually just listen to a lot of royalty free music and choose one with a decent beat! :)

[@timcaspers6498]

Joris en de draak has so much lateral and negative GeForce! One of the best coasters I’ve ever ridden

[@coasterbot]

Awesome! :)

[@l2m773]

Nope i dont really like it its very rough

[@coasterfan1017]

You should do six flags over Texas as it was the first six flags park. Great video

[@coasterbot]

I'll note that down, and thanks! :)

[@sarahfleischer3571]

thank you so much for creating this channel. Hope to become a mechanical engineer for Universal

[@coasterbot]

No problem, best of luck, that would be awesome :)

[@gio11138]

you sound like a How It's Made narrator :p great video harreh

[@coasterbot]

ha ha thank you! :)

[@ban_kz]

THANKS BRO!

[@coasterbot]

No worries bud!

[@dabooom1296]

Isnt the force which pushes the train down the positive and that one which pulls the train up the negative??? 2:58

[@coasterbot]

The reaction to the force, e.g. the way your body reacts to the force, is opposite to the direction of the force. Therefore, as airtime makes you ride us, negative g-forces force the train down towards the ground. On the opposite side, positive forces push the trains up away from the rails.

[@mattyorshin]

Great vid

[@coasterbot]

Thank you! :)

[@ajs4693]

well done

[@coasterbot]

Thanks!

[@bethanymarks9236]

at 6:59 just before the ride clip of icon what park is that? thought it was bpb with avalanche in the background but theres not a B&M there

[@bethanymarks9236]

nevermind just realised it's heide park and thats flug der dämonen

[@floris9182]

Hey could you make a video about the booster maxxx? Its a insane flat ride its 60 meters high and goes 140kmh

[@coasterbot]

I'll note that down, thanks for the suggestion :)

[@JakeBrickmobile]

Love the video

[@coasterbot]

Thanks! That's great to hear

[@TytonidaeIndustries]

so, one thing i have been wondering about, why do almost all modern coaster trains have even numbers of seats in each row?eg some have 2 seats per row, or 4 or 8 ext., but none that i am aware of have 3 or 5 or 7 ext, so why is that?

[@thewarf321]

You know I finally figured out why I dislike the music in your videos, it’s because you use the same looped music for 7 minutes straight. Maybe whenever you switch topics change up the song? Or maybe whenever you finish talking about something, show raw footage and audio of what you just talked about, then cut back with different music. Maybe you talk about the launch system on a rollercoaster, and then when you finish you cut to footage and audio of that launch system functioning then cut back to the next topic. Just some simple ways to make the atmosphere less stale. Keep up the fantastic videos harry!

[@coasterbot]

These are good suggestions, but the pacing of the video would be ruined if I did talk about something then cut to a video of it occuring. This would drastically increase the length of the video, as well as feel jarring as it happens 10s if time throughout. Music is definitely not my forte right now, and is something I need to work upon. I'll bear it in mind :)

[@jimmyhenders4131]

lofi hip hop radio - beats to relax/study to, you'll thank me later bro

[@MWolfFang]

So is this specifically the reason at least partially why people black out on the Sling Shot a lot too?
