Gyroscope

[warmaidens]

got one of these today for xmas, i wondered what it did!

[z00lky]

and this is in your phone

[XxBam28xX]

@Sp2391 yes there is, ipod touches have built in gyroscopes in them

[NickmanGiovanni]

Moment, or torque, is defined by the equation:

M = w x H

Where w (omega) is the precession rate of the gyro, and H is the angular momentum, or I*w of the gyroscope itself.

The gyroscope rotates around the black stand at a rate w because of the moment which gravity creates on it, thus keeping it from falling down.

Also, angular momentum is always trying to align itself with the torque, explaining the constant precession (w) which we can clearly see.

[smiche2]

I woned why dont they use gyroscopes in robot toys.They would be way more stable and able to walk without falling or looking akward.Also gyroscopes are used in big ships so that the waves in the sees dont take them down.Titanic i think was the first ship with a gyroscope.

Dear Santa......

[784563]

awesome technology!

[thegamerking97]

i agree i love how every comment is thumbed up

[dragodestroyer99]

i got mine from hobby lobby

[matter928]

try putting it on the tip of a pencil

[Sp2391]

My ipod touch can tell what angle its in. Does this mean there is a tiny gyroscope in it???

[wwwclnd]

@Sp2391 Accelerometer



[spellinganimals]

I have that exact same kind, and you just showed us the 4 tricks on the manual! LOL!

[GuNiShMeNt100]

i want one

[greenim]

To whomever is narrating this video, you have a very listenable voice.

[doh1959]

the challenge is to create lift by gyroscope then welcome to the billionaires club

[zcxvasdfqwer1234]

Nikola Tesla's suppressed flying machine was to have gyroscopes in it he said, "Through gyroscopic action of my engine...my airship will have neither gas bag, wings nor propellers. It is the child of my dreams, the product of years of intense and painful toil and research. I am not going to talk about it any further. But whatever my airship may be, here at least is an engine that will do things that no other engine ever has done, and that is something tangible."

[yoyoman240]

you forgot to put iPhones

[mjolnir1981]

Gyroscopes were used in ships to help them stabilize in the open sea. Obviously not any more

[D13fledermause]

So that's how motorcycles stay upright when the rider falls off! No way!

[iamaLobsterDog]

I learned about this in Physical I in college.

[freeloaderchriss]

is this like an accelerometer in iphones

[Ioganstone]

this pseudo science is so cool!

[medalofhonor31]

Never thought physics would be this interesting.

[Inimoulleb]

Id like to see a giant gyroscope with a motor in it....

[AnbuSoldier87]

angular momentum right?

[MrTangoRomeoDelta]

science!



[Ibuprofens]

uuuuuaaaahhhhhhaaaaaa -tim allen

[Loraxcoffee]

The germans used these in WW4 to guide their ballistic V4 missiles

[Shabe67]

YEAH, SCIENCE!!!

[Kale3193]

wow, so this is what is in my iPhone that tells it how it's moving

[eigentensor]

"the first thing i notice aboot the spinning gyroscope..."

canadian spotted!

[Morfar22]

Woo thumbs up for everyone!

[alekdaf]

i have one

[aviza12]

at first, i thought that the inner frame of the gyro acts like helicopter's blade - creating elevation (when it's rotating rapidly) and supporting it when it stands horizontally, but than i saw 1:49 ...

[cpinnago]

Brilliant.......Conservation of Angular Momentum at best !!!

[keffje007]

Very very interesting

[o0EviLivE0o]

this must be the most thumbs up video on youtube

[unsafe1413]

where to buy one?

[MrPhantomFury]

Awesome vid !!! Who disliked this huh !?!?

[lonflash]

Woah, this is amazing.  I want one

[Tjita1]

In modern aircraft inertial guidance systems are considered obsolete, as are mechanical gyro instruments, all of that has been replaced with either solid state electronics, or possibly laser gyros, but those are expensive and not really necessary with modern technology. But never mind that, call the 70s technology modern if you want to, makes no difference to me. :)

[ipadize]

PHYSICS RULES!!!

[perebraco]

anyone who thinks that science is boring he is wasting his life!!!!

i agree with @wowsux97

[anirban17aug]

WOW every comment has a thumbs up. Thumbs up to all. Amazing stuff feeling like a kid now

[falcosaurus]

hey man thanks a lot for this...

It reallllllllly helped me out!!

[userisdosser]

It is sad know that People in my country intrested more on horoscope

[Stoozor]

This is undoubtedly a toy I would buy to my kids so they get an intuitive understanding of the physics at play there.

[raghu23prakash]

The core of Engineering Mechanics 

[savilo2]

science is not boring. but the ways some teachers teach it is boring.

[DWAWrestling]

gyroscope.... AWESOME

[IIAndersII]

The germans used these in WWII to guide their ballistic V2 missiles

[hawkister]

i want one now...

[orionconflict2007]

levitating is not 2 far off

[TheYacine3tm]

NICE ! D'oh !

[furyberserk]

Is it possible to make a square one? If so, make a square one. I think a square one is possible. And letting it spin would be awesome.

[Peoples17Champ]

how can they put this in a Wii U controller

[ultrapluppen]

His voice alone was enough to make me like this

[MrCalvinGu]

There are some swindlers in China that sell those gyroscopes as a magical object!

[Rhomeozon]

where can i buy a gyroscope? what store? anyone near north hills? what kind of store?

[Hypastpist]

IT SPINS!!!!!

[SuperMoHo1]

Thumbs up if studying physics (Angular Momentum) lead you here...

[Ravek2010]

i want one!]

[GMixVideos]

he sounds canadian

[zilbiol]

it stores energy which resists movement, when the energy runs out it can't resist anymore

[Tanaerian]

Ah, trying to understand this for university. Lovely stuff, but so confusing. Torque-ache!

[Dablid77]

im going to buy one

[IAMTHECAPSGODLOL]

oh this thing is just disturbing

[DukoBenedicto]

lol I have the exact same one

[Joobacca0319]

i have that EXACT same gyroscope

[kontact666]

Bought it. I can witness it's working just like they show. The gyroscope costs 12 euro but you need additional 7 euro for shipping cost.

[xXMeganMcKenzieXx]

Dam, I broke my gyroscope and it turns out that I wasn't using it properly.

[onehundredand37]

could i have 1342 thumbs up?

[Neotyguy40]

For those that want to know, electronic gyroscopes (like ones found in planes), are NOT these mechanical physical ones. Infact, they don't look at all similar. Electronic gyroscopes are contained in a silicon chip less than a centimeter big, and use magnets and rare earth metals that allow for the gyroscopes to not move at all, even if shaken or explosively interrupted. Only high-powered magnets could disrupt them.

[Pr0fess0r582]

how many people instantly googled and purchased a Gyroscope after they watched this? {raises hand}

[jimmyPain2121]

troll gravity

[robopirinja]

Are you a wizard?

[cachibache777]

Very nice demo!

I've always been mesmerized by gyroscopes from the day I first saw them as a seven year-old kid until now as an old fart...

Now I'll be using them as a rehab tool for arm strengthening. Amazing!

[roelloos1]

take a gyroscope and stack it on another gyroscope

[eddyMx]

they really put this on an ipad2???

[gamer3386]

This is how UFOs work just add moving inside space and you have anti gravity machine you just need some sort of fuel that creates electromagnetic pulse (mercury) that pulses creating force to reflect of flying object that creates momentum for inside wheel and you have your self an UFO .

[SargoDarya]

a) That is the reason we can easily drive on a bicycle.

b) Perfect for balancing out a mech :>

[ggjoe723]

that is like the coolest thing ive ever seen

[Valenet94]

This is so awesome and now i want one.

[aleon1018]

I had a push screw handle? top as a toy when I was a kid and was always curious about it. The one I had would make sparks too. I was kinda sad when my dad sold it at a garage sale. There seems to be electric motors that use some of the basics of a gyro, but I'm not sure how. fascinating stuff though and many are never too old to be amused and curious. Id like to see how free energy can be incorporated with these.

[midnightjr3]

Would it be very difficult to make one of these?

[koolentkush]

cool hhuhn ,, Well that explanation was quite cool and also gives me idea of building the biggest ball

[starwarsfan715]

if they only made it so big that people can get inside the spinning wheel inside

[Ignorantf00l]

I always knew that Gyroscopes are important in navigating, but I never thought they are this awesome. My jaw dropped.

[Szasz0407]

nice demonstration :)

I wish there were more of these.

[PkerTomy]

i had one of those as a kid lol good yimes

[xXxDANMANxXx]

if you didn't at least smile a little at 1:28 you're just a straight up boring person, my friend and I discovered gyroscopes when he had some hard drives he was about to throw out, we plugged it in and tried to move it around with our hands and it resists everything sooo coool

[44eelz]

like a top

[wowsux97]

Anyone who says science is boring is an idiot.

[NamishuHatake]

Amazing

[dan10k12]

WHAT IS THIS WITCHCRAFT?!?!?!?!?

[tanddant]

is this indside my iphone

[kontact666]

I want one!!!

An angular momento? Is it the force that resists attempt to change the device position?

[viktorob]

Wow, thank you so much, very well explained. How did apple fit one of those toys inside the iphone 4? Gyro games and utilities are very fun. It gives you the sensation of 3D.

[TheSDcard]

AND it costs only 7 $ i have the same as in the video

[movierater3256]

Where do you get that?? I can use that for a science fair project if I can find where to buy it

[Shiroblack]

i love you

[MrVidManiacMilo]

I WANT ONE!

[MrVidManiacMilo]

LETS BEAT ALL THE THUMBS UP. If you want one of these thumb the comment up!

[banananana621]

That's so awesomeeeee! And it's got science involved too!

[isurfu2ube]

When will Scientists make a flying car damn it!! I am tired of the engine and wheels that roll by using air pressure with tires!!

I wanna fly not roll on the ground!!!

[drunkymistake]

physics is awsome!

wher can i get one of these?

[99johnface]

I love this so much it is so awesome thanks

[blogtepic]

wow

[DarkSoulX19]

i learn alot from this video lol

[asen97yoyo]

WOOW! Physics' great

[xRothenx]

Studying angular momentum right now, really helpful.

[Mikzoy]

I just bought exactly the same toy, and I'm in love with it, I was looking for an explanation, and this video is great, thanks.

[danielglavas]

i like videos like this.they're great

[panzarw]

people who know answer this please:

if a gyro had 2 rotating in opposite direction wheels then what will happen ?

[nhickvicky]

top works like that.....I want to do the one in 1:41 using the top but that would be impossible

[rohan1ize]

science rocks........

[noobenstein]

This is also what makes bicycles stand up. Thats why its easier to balance while moving on a bike than standing still.

[tize79]

never tought i would like learning something O_O

[chakathewolf]

I know that gyroscopes used in inertial guidance systems are more complicated than this, but they must precess just like this one. How is that compensated for so that the aircraft doesn't rock back and forth?

[ThaDamian]

so thats how ufo's work...

[kooljosh100]

thats cool!

[timone1002]

its simple. imagine as the wheel is spinning you put pressure on it to lean to one side. so if the wheel wasnt spinning it would want to lean to that side. but because the wheel is spinning that force is carried over to the opposite side(when the wheel gets there as its rotating) which counter balances the original movement to one side.

[bersek23]

you really gotta love physics.....

[erico1st]

I bought one of these immediately after seeing this :D

[spacescience100]

Good videos

[raikadoygo]

amazing

[gamerfuture]

incredible video

[gamerfuture]

awesome i love physics

[ToothMusic]

Gyroscopes are so cool.

[tnuomnhoj]

baffled.

[joeplay101]

i had one of these when i was a kid. never knew it could do all that stuff. it came with a piece of string, always wonder what that was for.

[jihadpizza]

Very Cool Stuff. Thanks for uploading. =) 5/5

[rysterf8]

If someone made a giant one with a generator that spins it automatically (like an aircraft propeller), will it hover like a flying saucer?

[smitehz]

physics is awesome.

[kashanjafri01]

Really Informative Video, Thanks

[kavehmoh1238]

where can i buy a good quality as in metal Gyroscopes

[rhadiel]

Quick question... what happens to a gyro in zero gravity?

[BergerKing064]

It remains oriented in space.

[persaudchris]

that was an awesome and interesting piece of work

[muzammilali007]

Awesome device.

[Chibsforce]

Wow...Amazing!!!

[Hakuo91]

This video it's very interesting...

We can learn a lot with vids like this one!!!

[clementbourdarie]

2:03 2:40 I did'nt think it was able to do this!

[LuniaVideo]

Awesome and informative video.

[MoskowFreak1111]

add some batteries and a engine and... I should make that

[Thymonico]

I got one for christmas! :D

[dreamy2]

how did people keep the gyroscope spinning in the mars rover?

[PyroTomas]

i like youtube cuz of vids like this

[engpolo1]

i love this

thanx

[gyropropulsion]

I also like to react with the remarkable effect of precession on the spinaxis- directionstability. Please look at my youtube film, search: thermosynchronics

[brumanima]

is this gadget inside most of the smartphones?

[1Sentient]

Those are accelerometers

[NekomimiNinja]

that would be an accelerometer, not a gyroscope, brumanima

[ronmann606]

@brumanima naa in some smartphones is an accelerometer, which is a solid state component with a microscopic semiconductor flap to sense acceleration. A gyroscope is an old way of detecting acceleration, although it has advantages, it won't fit in an iphone.

[supergiff8]

No, an accelerometer is found in most smartphones, Accelerometers detect the angle and velocity of the device and sends data to the CPU accordingly for a reaction.

[cleric022684]

no but it is called like that

[iamazn2000]

All we need now is perpetual motion

[calfan3]

i want to know one thing....how do gyroscopes help austronauts know where they are in outer space?

[barrinmw]

As you move in a direction, the gyroscope tips in the opposite direction by an amount proportional to how fast you are going, they then configure in time and plug that into a computer.

Velocity X Time = Displacement

[Kewkky]

Prevents them from spinning out of control.

[Kokosiak1]

when the gyro is mounted in special frame, the rotating wheel maintains its direction independently of position of the frame. when you spin the gyroscope that will rotate for more than 2 or 3 hours, you will see, that wheel which became to rotate upright will spin in other way, because the earth is rotating, and the gyro maintains its angle.

[DaGipsyKing]

A timeless toy.

[ShyneDark]

SO AWESOME!!!!!!!!

[griever619]

great vid!!

[dude78987]

Is that the Tedco Original Toy Gyroscope?

[romania4uluv]

Yey! Thanks!

[ducttaperulestheworl]

my gyroscope had lost it's stability T_T

everytime I spin it it shakes and vibrates a lot.

[shojunkayoi]

Amazing. I don't understand those things (and they freak me out a little), but they are fascinating devices.

[QCW089]

does anybody know how this thing actually works in the V1 & V2 rocket or the ICBM n guided missile??

[chaosrealm93]

i think it had a similar setup as 3:25, except the "contacts" were connected to the rockets fins

[aqwiz]

actually it is based on the movement of the gyro, the gyroscope (or multiple gyroscopes) are held in place in a mount, and the mount gets rotated by motors, which increases the resistance in one direction (opposite the movement) and it transfers to the mount, since there is nothing on the mount or rocket holding it in place

[Keex11]

the principle is to have a fast spinning gyroscope that does not change the angle of it's spinning axis. that way you can scan the relative angle between spinning axis and the rocket and have a precise measurement for the direction the rocket is pointing at. most rockets (or the ISS for example) use multiple gyroscopes for measuring different directions in space. in the video this principle is shown from 3:30~

[bob26drft]

After the information has been received from the gyro about rotation, it is put through a simple processing unit (depending on the complexity of the device it could be very advanced as well) and the resultant data is sent to the control surfaces, which, combined with an altimeter and speedometer and other instruments, can correct its course accordingly.

[PokemonmasterCJ]

i have the same gyro

[dty2dty2]

Excellent videos: many thanks.

[xtruder02]

physics rulz

[Deepsand101]

WHOA SO COOL!

Not.
