Gyroscope

[@greenim]

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

[@jackas95]

today i have gyroscope in my smartphone

[@saprasla]

amazing to learn how scientists exploits law of physics to develop amazing technology!

[@GloomyHouse]

WHyYYYYYY!!! ...someone please xplain to me the physics behind the part where it appears to defy gravity.

[@chanman201]

my mind is blown

[@surberboy]

Will one spinning gyroscope sit atop another and stay? That would be cool to see.

[@MrMeanderthal]

I had one of these 40 years ago and they're still exactly as I remember, colour and all.. it's cool they still make them..

[@danosqu]

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

[@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.

[@CrazyJoe136]

Incredible isn't it? Once you have a great teacher like this, you can become interested in anything.

[@denisliossi]

Very important information and considerations. Thanks!

[@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~

[@gulllars]

Interesting... Maybe i'll have to buy a couple of these. I already know a bit about the gyro-effect in practical scenarios (i ride a motorcycle), and i've got a gyro-ball thing for training the lower arms (a fun device for quick brakes between hours at the computer), and a gyroscope would be a great thing to mess around with.

[@Ignorantf00l]

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

[@LadyTink]

Also, angular momentum is the one thing I've had the biggest issue learning how to program into a physics engine.

[@z00lky]

and this is in your phone

[@Pr0fess0r582]

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

[@persaudchris]

that was an awesome and interesting piece of work

[@Interzone88]

Been looking for a video that demonstrates the properties of Gyroscopes. Thanks

[@michaelyo]

Think of it this way. If a downwards force (say gravity) acts on the right side of the wheel it will have a tendency to fall on its right. But the fact that the wheel is spinning; the right side is now on the left and the downwards force is on the left side. Same condition for the left side of the wheel spinning to the right. Its explained well by angular momentum. The sum of angular momentum (in direction of sum of torques) makes it precess hence its spins (Not the wheel, the whole frame)

[@Bugglesfan79]

Another awesome video 5/5!

[@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.

[@eigentensor]

"the first thing i notice aboot the spinning gyroscope..." canadian spotted!

[@Valenet94]

This is so awesome and now i want one.

[@AleifrLeifrson]

@fallenspirit123: The Chikyu Goma was pretty trashed after a couple of days. I don't think I treated it badly, it probably just isn't very durable. I don't know about this one though, haven't tried it.

[@spellinganimals]

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

[@anirban17aug]

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

[@noblessus]

The explanation of how it works is rather simple: A spinning disk resists changing forces to its orientation due to inertia. When it is positioned as in 1:46, in order for gravity to make it fall, it needs to make it change its orientation; but the force of inertia is greater (depending on the spin-speed) and therefore, since gravity cannot change its orientation (make it tilt) then the gyroscope is stable in that position. When the spin decreases enough, gravity wins over inertia and it falls.

[@Pegasusthebeyblade]

i have a suddden earg to bye aa gyroscope now

[@fallenspirit123]

yeah I know chikyu goma is 17 euros but in U.S. dollars ilts like 30 or so isnt it? and I see your point :)

[@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.

[@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?

[@mannequinfukr]

it is recommended because spinning by hand will not be fast enough and those high rpm motors will damage the rim

[@DiarmuidNZ]

Excellent videos: many thanks.

[@rockyIV0100]

big plane carriers also use gyroscopes for their stability

[@vitruvian8807]

What if you stack two of them together?

[@j0rr]

well, gyroscopes are used in planes, they must be started on land because when youre up between or above the clouds then you know your flying angle.

[@falcosaurus]

hey man thanks a lot for this... It reallllllllly helped me out!!

[@Incuby]

Damn.. i dindt know physics can be so interesting ^^

[@DaCheeseKing]

did u get that gyroscope from the museum of natiral history in nyc

[@Szasz0407]

nice demonstration :) I wish there were more of these.

[@KingOfTheStoneH]

wow just incredible, i love it

[@erico1st]

I bought one of these immediately after seeing this :D

[@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."

[@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.

[@callmeYEL]

i dont understand, how does it maintain its balance?

[@TomShootsPhoto]

Really good video, explained the gyroscope very well.

[@gwend01yngurts]

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.

[@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

[@kontact666]

I want one!!! An angular momento? Is it the force that resists attempt to change the device position?

[@Shabe67]

YEAH, SCIENCE!!!

[@therealjordiano]

this blew my mind lol, srsly

[@784563]

awesome technology!

[@iwan0t0smith]

if you were to put a propellar in the spinning bit would you be able to produce a stable simple helicopter

[@Chronically_JBoo]

OMG this is sickkk I want to buy one.

[@drunkymistake]

physics is awsome! wher can i get one of these?

[@ducttaperulestheworl]

my gyroscope had lost it's stability T_T everytime I spin it it shakes and vibrates a lot.

[@danielglavas]

i like videos like this.they're great

[@AnbuSoldier87]

angular momentum right?

[@Pl4rk]

this is very interesting, nice vid

[@LFSPharaoh]

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

[@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.

[@Cheeky_Goose]

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

[@xRU16YTx]

well when you spin somethign it gives it gravity right?

[@umagihirou]

can you use floss to spin the wheel?

[@kashanjafri01]

Really Informative Video, Thanks

[@HansVanIngelgom]

Huh? I thought the mars rovers used laser gyro's? (sending laser light through a spool of optic fiber and measuring the phase difference as it comes out?

[@fakeaccount663]

i have the Japanese 63mm Gyro-Top (Chikyu Goma) its the best toy gyro you can get

[@lolzdecap]

Awesome! Mine is about twice the size, but you have to be careful with mine. It almost took my finger off.

[@cpinnago]

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

[@hakuuo]

This video it's very interesting... We can learn a lot with vids like this one!!!

[@KyleAButler]

I have one of these now!

[@Rhomeozon]

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

[@tanddant]

is this indside my iphone

[@gamerfuture]

incredible video

[@presidential777]

To all my future entrepreneurial scientists: WE NEED TO RESEARCH THIS TECHNOLOGY. This is the start of space travel.

[@jihadpizza]

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

[@g2g144]

Isn't that like defieng gravity

[@freeloaderchriss]

is this like an accelerometer in iphones

[@nopoint313]

Damn dude... The things people think of...

[@QCW089]

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

[@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 ...

[@rhadiel]

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

[@kai2698]

so that's what it does lol. as a kid i thought it was just some toy xD

[@dkdabekar1]

awesome !!!

[@assen97]

WOOW! Physics' great

[@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.

[@fran6b]

Internet is awesome! I red on a sport wedsite that a doctor use a gyroscope to do something with concussion. What's a gyroscope? Google image it, than google video it and here I am. Wow! This thing is awesome and want one! Quick turn by eBay and I will receive my gyroscope soon. All that in a second without moving my rear. I had to tell someone. : )

[@dude78987]

Is that the Tedco Original Toy Gyroscope?

[@Kewkky]

Prevents them from spinning out of control.

[@thegamerking97]

i agree i love how every comment is thumbed up

[@AleifrLeifrson]

I have the japanese Chikyu Goma gyroscope. I think I should have bought this one. = /

[@shirubiu]

whats the price on one? what kind of shops can i get it from?(except internet)like gift shops or what? please reply

[@AleifrLeifrson]

@fallenspirit123: I'm not trying to be snappy but, you would never expect what? I'm not saying this one is better, I'm just saying it seems like the Chikyu Goma sucks. And BTW, I bought the Chikuy Goma for £ 17.

[@DieGearschten]

its physics, it wants to keep his "rotating impulse" same reason why u dont fall off your bike so easyly

[@fallenspirit123]

Hmm, realy? wow i would never have expected that since this one is like 7dollars and Ive seen the chikyu goma for like 28+

[@brumanima]

is this gadget inside most of the smartphones?

[@MDolan]

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

[@o0EviLivE0o]

this must be the most thumbs up video on youtube

[@AleifrLeifrson]

@fallenspirit123: It costs 17 pounds, you're right that's about the same as 28 dollars. But euros are about the same as dollars.
