coriolis effect (2-11)

[kirkbutler12]

I want this video on my WA 3050 phone.

[BrendanKearnsMusic]

Northern hemisphere example: Jetstream.

[DamionCrane]

FUCK SOPA!!!

[sharamandarata]

:mindfuck:

[Benson429]

This helped a lot. Thx. :D

[fryejames12]

This video went viral on Vaduz

[alien16759]

who else is hear because of modern warfare?

[fana1234able]

wow this helped alot

[TaedetMeVitae]

Pollice su se vi ha mandato la Piseri

[XxSenorBanoxX]

@Damirok im on an ipad so i cant thumbs up but heres a message saying thats why i came :D derppppppp

[dannymann1995]

look at this on wikipedia :L i was scared until i saw this many thanks

[dudleymurphy1]

Thank you very much this helped me so much. This was an easy to understand explanation and I appreciate it very much! Great Video! :)

[csogoreny]

looks like if I spinning enough faster i can throw and then catch the ball?

[Damirok]

Thumbs up if MacMillan sent you here :D

[FlowControlMagazine]

This is a nice description of the Coriolis effect, which is particularly helpful if you are struggling to understand a written description of the Coriolis effect.

[anatureperson]

I liked this. Thank you. :)

[secanesam]

no matter what your still gonna shoot his arm off

[Theedrumguy1000]

thanks lady im gunna get an A on my test tomorrow

[TheDoviverse]

@tairnan u got for a sec or is that really a calulation

[tiarnan76]

If you calculate x1 to an inverse proportion of directional velocity/acceleration and multiply it by variance.025 (y) with subsummation of the kerkin hydro chamber of love you'll realise you'd have been better off by having a go on the swings.

[irisheyes6363]

lesson learned: don't play catch on a merry-go-round

[IcySkeptic]

Why is there a "velocity effect" in only one direction >_<?

[worldcitizen4]

I saw the video again and noted that there are not any error, the objective is to prove the direction of the winds in general , not the case of ciclones that is expecial.

[worldcitizen4]

This video explain more or less the direction of the wind in a anticiclone and the direction of the ocean current but not the direction of the wind in a cicline. To explain the case of ciclone should be possible to do the ball go in the direction of the second person in the merry-go-round even with change of the position of this person, in fact the wind in a ciclone don't miss the target, they go to the eye of the ciclone.

[MrKrewie]

what does this have to do with cod ?

[MontezumaUH60]

@MrKrewie if I remember right, Captain McMillian explains the Coriolos effect is a factor when sniping Imran Zakeav

[jdogbo1]

@mjsphere, haha that's the only reason j looked this up haha I'm playin that level right now :p

[bestamerica]

'

depend on this spin RPM,,,

fast spin or slow spin RPM

[pcbb01]

same concept with one of Einstein's relativity theory, the spaceship thingy

[mjshere]

damn you MacMillan you never taught me the coriolis effect

[oldblubblub]

Take THAT geocentrists.

[Pure360x]

and what would happen in the equator??

[captainchu]

FUCK COD, even though I like it, it is completely separate from this, this is physics...

[AdrenAlineSKKE]

oh FFS... I come here to see a peacefull video about physics, and all I see in the comments are some internet inciters dissing a videogame... wtf?

[Meowingsoft]

hmm, if i fired a gun towards the northpole from the equator allowing for the coriolis effect. Then in 12 hours the bullet will hit me if i stayed in the same spot and the bullet travelled at he same speed as the earth rotating in the equator. DONT TRY IT IF IT WORKS YOU WILL BE KILLED BY YOURSELF

[Qw3rtypop]

@Meowingsoft Someone forgot to include gravity.

[kiera791]

@CameronRawrr hey dude dont be bashing on gay people dont say the word fag!

[WeAreChuckNorris]

yeah yeah CoD .. bla bla.. now learn science!

[lmaIia]

What does this have to do with Call of Duty?

[degerte]

@lmaIia one shot, one kill mission

taking a shot from 867 meters, in which the gamer has to keep an eye on the wind and the turning of the earth

aka corliolis effect

[sandmangfm]

i could give a fck about call of duty.. go science!!

[dreamhomeaustin]

why doesn't water drain straight down on the equator? hmmm

[Huddiethegreat]

UAV is online

[Zolrak666]

So, when do they catch the ball?

[thebalance229]

my brain wants to EXPLODE when learning this!!!

[usedive]

@thebalance229 so does mine, I had to pump a gallon of water in my ears just to extinguish the smoke seeping out; always a bad sign.

[Woolfrey]

@thebalance229

It's easy, if you can calculate the vector algebra for acceleration...

[JSnyder49428]

I wonder if you could control the velocity of a certain object so that you shot it directly north (from the equator for the sake of the example) on a trajectory that should take it past the north pole to the opposite point on earth, but instead have it some back to the starting point because of the Coriolis effect.

[SwiftSilentDedly0321]

I wish someone would put a video about Eotvos effect, its in relation to Coriolis.

[ShivanandPattanshett]

Nice work!

[catastrovision]

Remember what i thought you, keep in mind variable humanidy along the bullets flight path, at this distance, you also have to take the coriolis effect into account.

[NzVii]

I Was Wondering If You was spinning Fast enough you could hit yourself with the ball you thrown :D gonna try it XD

[JSnyder49428]

@NzVii you would need to be spinning very fast, OR you could use something that travels very slow when thrown (like a baloon) and if it takes the same time for the object to be thrown from one side of the merry go round to the other as it does for you to make 1/2 revolution, then it should work.

[TheGreatDissolve]

this video contains the secrets of space and time. how many noticed so far ?

[RonBurgundy161]

For fucks sake, almost all videos that interest me now are flooded with comments from Call of Duty fanboys.

[Oudl3000]

Pfff call of duty 4... real nerds watch it cause it was on simpsons ^^

[cloners1]

weareborg359... i thought of looking this up cas it was in there too at first, then it popped up in my science book and didnt make sense in the game or in the book. so here i am

[XCookiepantsX]

Thanks.

[PivotLives]

And this helps me assasinate imran zakaef because...

[Freedomfoe07]

@PivotLives that the bullet goes straight, but due to the rotation of the earth, the bullet may go to the right or to the left of Zakhaev. :D

[camel3451]

wow this would be a good topic for a report

[camel3451]

i have seen better videos for a science project

[maxendenia]

and what about if you are in the middle of northen and sothern hemisfer???

[Iszil]

@maxendenia Aactually, if you are exactly in the middle there's no such effect.

[sarouelala]

wow..physics are a great stuff..

[BraytonCarnot]

Ottimo video!

[starnjuy]

zakhaev created 6 accounts 

[pulsery]

so if a bullet is going straight it would seem to be moving off to the side cause the earth is rotating?? if i have the right idea then how does a sniper predict where the bullet will go

[zuzerial]

@pulsery The sniper is able to know where the bullet will go based on reading the winds through the scope, as well as estimating the distance to target and calculating the drop of the bullet over that distance. The coriolis effect doesn't change the flight path of the bullet, but changes where the target is going to be at the point of impact, so the sniper just aims a tiny bit to the side of where they'd normally aim. The side they aim to is based on what hemisphere they're in.

[Griesmayer]

if it weren't for that video game, a lot less people would have watched this video. I like the idea of incorporating science into video games...makes common folk get interested in what they would otherwise deem a dead bore and would have never bothered to look up.

[Blade5276]

creepy eyes

[YDG777]

the reason it gets deflected to the right in the northern hemisphere is because the parts of the earth near the equator have a faster velocity than the parts more towards the poles. When something travels from the equator towards the northpole, its rightward component is faster than that of the northpole, or any area near it, so it will be moving right faster, and land rightward of it, rather than at the point it was aimed at.

[brookeshared]

Thumbs up if you actually have to watch this video for a purpose such as science class.. and not Call of Duty 4! :)

[poposisa]

@brookeshared a_AJHAJHAjlahjaaahjahakajhajha­haj lame cod

[toomuchtohadel]

@brookeshared true that

[SUMD123]

@brookeshared Why is education yourself on a phenomena mentioned in a video game NOT a purpose?

[WiiThoko]

@brookeshared lolnope

[smellycow6]

@brookeshared  dang ya got me :P

[PDW008]

there's a mistake at 1:52, the first arrow is directed wrong. The earth turns to the right so when you draw a line on the surface from the equator to the north pole the arrow will deflect to the left.

[Dm3qXY]

@PDW008 you are right; i suppose the arrows in this case would represent the correction an airplane pilot has to do... but indeed, the naration is clearly not in sync with the animation.

[macos1234]

@Dm3qXY Actually the vid is right, that is not the correction and airplane pilot has to do. That is the actual direction the plane is going if it's heading straight north. It moves just like it feels a force pushing it to the right. This is the situation demonstrated in the merry going around at 1:00 . This is one of the usual misconceptions regarding the coriolis effect...

[Dm3qXY]

@macos1234 yes , you're right (the reference system is the rotating earth, the correction is the other way).. i had some troubles understanding the other two pairs of arrows (not those starting at poles or equator, but the others) they come clear as long you think a them as resulting from two components (one along parallels, and one component along meridians) .

thanks for the enlightening headache :)

[Dm3qXY]

@PDW008 hey man, just had a clearifying discution with macos1234 (check the comments), we were wrong man... so wrong...

[PDW008]

@Dm3qXY Ok, well I had the idea that the earth would turn underneath the plane or whatever it is that travels upward and for that reason it would seem as if the plane deflects to the left. I understand the concept of the greater velocity at the equator but it's just hard to imagine that this works in the air (for a rolling ball I find it much easier to get in.) I came upon this video while I was trying to get a good understanding of the foucault pendulum, any tips? I built one but it didn't work

[Dm3qXY]

@PDW008 never tried it, i guess you'd get better results as you go for higher scale.. and yes.. some serious patience is required.

go big ;)

[kellymduran]

Ok thank you! NOW I get it! And up, right, down left :)

[rowanationer]

this is a headfuck way of analysing a simple thing

[nagylaszlo71]

ohhhh, what a stupid american pronunciation, accentuation and nasal twang ;-((((

[Phillip095]

My head is going to explode from trying to understand this... again...

[rowanationer]

@Phillip095 tell me about it. who is this coriolis guy, and why is he complicating things with this conceptual BS?!

[Gametoast53]

@Phillip095 Me too -.-

[Double303]

Don't get it....

[Dvdvideooo]

So thats how they do it in Wanted! =D

[Double303]

People that explain it like robots never teach me a damn thing~! Can someone please explain this to me in plain English? Please?

[deadhues]

@Double303 Robots? You mean clear and understandable?

[Straif5]

@killaturk68

Not much, but they mention it in Call of Duty.

[CaptainObvious607]

Ive been looking up on why prevailing winds come from the direction that they do and ive been sitting here looking at diagrams of the 3 cell circulation system thingy AND IVE BEEN GOING OUT OF MY FREAKIN MIND trying to under wtf the winds randomly change direction but i think this video explains it really well. The thrower throwing from the middle to the outside, the middle would represent the pole and outside would be the equator and ditto in reverse. Thnx alot for uploading!

[TheThruster24]

PEDO BEAR ;)

[Aneurythmic]

FYI, the final section of the video appears to be incorrect. Objects from the frame of reference of the Earth (i.e. the Earth being still) will move COUNTERCLOCKWISE, whereas objects in the southern hemisphere will appear to be 'forced' in a CLOCKWISE rotation.

Correct me if I'm wrong, but I believe this is the case.

[getzi1234]

i am here for cod 4 i wanted to understand this efect

[cybermike2000]

japp thanx

[gingerkid417]

That's why I'm here

[897833234]

thank you to the creator!

[DonnachaBurke]

Way more easier too understand than Wikipedia.. my God

[richyoon11]

I'm only looking for what Coriolis effect means because of COD4 and i like how he said it in that game.The weird thing is it hits is face but his arm comes off

[jasmenter]

oh yeah julius we are all here because of the cod 4 z!!!!

[domyaska]

EXCELLENT ! THANK YOU VERY MUCH

[falloist]

McMillan:"You also have to take the Coriolis effect into account"

[NARproductions]

Toilets flush in opposite directions in the northern hemisphere to the southern

[CallMeTheHunter]

what if the carousel was spinning so fast that the kid threw it and it spun around and the other kid caught it? hows that for cory ellis effect bitch?

[JeromeHattKronen1664]

@CallMeTheHunter I think it's possible to do that.

The ball would appear to orbit near the center once, then fly out to the other side.

[CallMeTheHunter]

what if the carousel was spinning so fast that the kid threw it and it spun around and the other kid caught it? hows that for cory ellis effect bitch?

[CallMeTheHunter]

i heard this in COD but i didn't care. i looked it up because i heard it on shooter so eat that bitches

[HomelessSon]

Lol I'm just here becuase I'm taking astronomy and the book did a very bad job in illustrating this merry go round example.. Great job here though! *5 star*

[Cratssss]

Very good explation . It will be very usefull to my project!

[loganm133]

to all saying i had perfect headshot and still got him in the arm must not have finished cod4 cause if u did u will know u get to pop a bullet in his head at the end

[WeAreBorg359]

@loganm133 OMG, I wonder what number person I am who looked up this video because it was on Call of Duty:4 ...lol

[connorking09]

a better example Lady would be......lets say a sniper? the catcher is the target. the thrower is the sniper and i think the ball should be? a bullet! you know u wanted to use my example....but you didnt want to scare the kiddies in thier science class. shame. my example is the very first thing that comes to anyones mind when they think about the coriolis effect. LMAO

[Straif5]

My guess is people come here looking for the refferance in COD 4 (One Shot, One Kill, for those of you who know the game)

[Plutoniummatt]

@killaturk68

its amaaaazing

[ShaneIsStillAlive]

Actualy. I'm not here for cod4.

Actually, a little bit.

I saw it on cod. Forgot about it.

THEN

I heard Cody say something about it on The sweet life of Zack and Cody on deck.

And was like

COD4 REFRENCE.

-looks up

-ends up here

Done.

[Straif5]

When did they mention it?

[ShaneIsStillAlive]

@Straif5

some episode where they were out on sea and one twin was arguing with the other.

I don't know, I don't watch that show. My sister was watching it.

[Straif5]

@ShaneIsStillAlive

Oh. Neither do I. Just wanted to watch the episode for the refferance. 

[ShaneIsStillAlive]

@Straif5  It wasn't all that big of a reference. Something like, "No Zack, if you follow the rules of the Coriolis effect, we wont end up by land" and blahblahblah.

[Straif5]

@ShaneIsStillAlive

Oh. Well, guess I just saved myself several hours of retarded shit watching then.

[bv90andy]

it was the first way of actually seeing that the earth was rotating around its axis

[GODLIKE20000]

"shit! ma legs all busted up, you're gonnae have to carry me mate!"

[UpBeatJoker]

@GODLIKE20000

Does it mean that when you shot the bullet, the bullet kept going straight in direction towards Zakhaev but the earth turned while the bullet was in the air so it appears that the bullet curved when really it went straight and just everything on earth moved?????

Pretty much

Bullet goes straight

Earth Turns so everything on earth turned also

Bullet still going straight from rifle but misses because the person moved?

[mrcowboy10001]

yes but just a little most of it was because of the wind

[Straif5]

Basically. So if it hadn't been for it, Zakhaev would be dead instead of one-armed.

[connorking09]

@UpBeatJoker yeah man. when captin mcmillian told me to take the coriolis effect in account. i did and i still shot his arm off. no matter how many times i had the perfect shot on his head it always blew his fukin arm off. ONE SHOT ONE KILL

[will666devil]

nice

[MegaThedrummer]

im here for cod 4 lvl

[archis84]

hmm. what if the earth does not rotate, but everything else rotates around the earth? i just cant fully understand this and the Foucault pendulum. In example, does it prove that like traveling by plane to east you spend less fuel that traveling to west?

[DrawingDude14]

Im here to study an exam XD

[JordanDaleMorgan1]

how did you know ? ur awesome

[kkflashboykk]

i am xD

[quimsolls]

@JuliusCeasar223 haha too true my man

[Onyxforce]

yeah, that one line from mcmillan gave this video a lot more views.

[Danzey12]

i watched about a second of this for cod4 then i saw the best way to open a beer thing in the related vids and immediately switched over,... boobs beat cod any day...

[GODLIKE20000]

yup :)

[Silaninil]

@JuliusCeasar223 actually i'm here for marine science class * sweat drop*

[gtamodman122]

@JuliusCeasar223 i came partly for thisreason,but by the thumbs up for your comment i think most people came here for this reason i came cuz i wanted to understand what effect it has at sniping,a question generated by cod4 so looks like youre right :-)

[JuliusCeasar223]

@JuliusCeasar223 HOLY SHIT 23 thumbsup and like 40 replies damn this is the best comment ive ever made

[areanem]

@JuliusCeasar223

yes sir, yes I am!

hard to take that into effect when i dont know what it was

[AngelzInTehAfterlife]

@JuliusCeasar223  lmaoo im not. i need this for when i go hunting. i ttake shots from over 1k yards

[umean123]

@JuliusCeasar223 not me

[maxendenia]

@JuliusCeasar223 fuck you are so right!!!!!!! hahahahahaha

[joanmesa]

@JuliusCeasar223 YEH U REALLY SHOULD CONSIDER THE CORIOLIS EFECT BEFORE U KILL THAT BASTARD ZAKAEV!!!

[plazaff]

@JuliusCeasar223 LOL.Your Right.The Part Where U Have To Snipe Emrand Zakaiev.

[tacticiankid]

is it pronounced the way its spelled or since its French, have a different pronunciation? I pretty sure Macmillan said it the way its spelled but my bro says its pronounced like Coraloy any way every one in here or just about looked this up thx to cod4

[Macontoshhelp4U]

i know i wuz playing and macmillan wuz like keep in mind variable humity and the coriolis affect along the bulets flight path

[juicebox714m]

Because the coriolis effect causes the bullet to deflect ever so slightly to the right or left depending on which hemisphere you are in. So when you shoot that dude out of the building with the barrett the bullet deflects/curves to the right as this video would suggest.

[popiposo]

btw, in COD4, or as a sniper, how does the Coriolis effect affect the sniper?

P.S. Im not good in science or physics. lol

[Alisterwolf66]

To a sniper, the effect would be minuscule, at best - the distance traveled by his/her projectile will likely be a mile or less. Not much time or distance for the effect to be noticeable!

On a bigger scale, such as a trans-continental flight like that of an airliner or ICBM, its effect varies according to the object's speed, and is much more pronounced.

In short, the effect is time- and velocity-dependent, because the earth's rotational speed is fixed.

Probably didn't help much, did I? lol

[ynotmoney2]

i wer playing cod4 and they sed the corriolis effect and i wer wondering wat it was

[Spike1300]

same lol

[Ace5858]

You know, that game was the only reason I remebered that name when I took ecology. "We gotta take the coriolis effect into consideration" Lol.

[Orion8888888]

neat!

[Nimfurion]

i remember when i took the coriolis effect into account in call of duty 4

[jadberro]

sure but in the game it made no differance it was the wind

[chinesestation]

lulz

[Salguodelaev]

@Nimfurion ahahahha yeah me too. Zhakev got lucky and the bullet curved into teh guys nuts standing behind him. I rofld.
