Where the wobble might hinder the gyroscope example, it does give a great example of the low margin of error when engineering something for use in microgravity environments.
Awesome presentation! I love seeing the oscillating stabilization effect in free fall. Euler would love this. Difficult math even 300 years later. Thanks.
Could you use strikes of electricity on a free floating gyro to rotate it and to keep it stable. I ask this, with the thought that an electrical Arc has a pushing force.
Do gyros precess in the ISS as on earth? I observe in the video that it has rigidity. If it does not precess like on earth, then you can prove that you are in space AND also determine how far you are from earth, by judging from the rate of precession corresponding to the velocity of spin of the gyro.
The two videos: "Gyroscopes/Angular Momentum"; assisted a lot with understanding these concepts in my Physics course. Appreciate the video from almost 10 years ago. :)
is the orientation of the gyroscope stable relative to the direction of down or relative to its initial orientation? in other words if an ideal gyro were spun up on the ISS and could run indefinitely would it appear to rotate relative to the orientation of the ISS?
The ISS keeps the same side of the station pointed towards Earth all the time. This means the ISS rotates once per orbit. I think the gyro would require an outside force to make it rotate with the ISS. If the gyro is free to move independent from the ISS, I think it would appear to rotate with respect to the ISS even though it's actually the ISS which is rotating.
Relative to its own. From the perspective of the ISS everything is effectively weightless. Even though gravity is acting on it, it's acting on everything else at the same rate so it all cancels out. With no obsevable torque from gravity, you don't see precession like you would on earth, and after "torqueing" the gyroscope it would keep a constant angular momentum
How do Gyroscopes work in the vacuum of space/the absence of other planets or a sun? You can see this presents many problems/Coordinate systems and fields. Without actioned on by external force it remains a closed system. Could I incorporate the Searl effect into a Gyroscope and what would that look like? Space is the perfect environment to test this.
great video, would love to see any other experiments using gyros in space, a good way to reduce the effects of friction has to be magnetic bearings. would making the gyro spin up to 66000 RPM make the moving force 10 times stronger? so many questions bounce around my head, have you developed a variable density gyro using magnetics? whats the fastest speed you have got a gyro in space up to and what happened? i have subscribed to your channel and i am working my way through your 5 year video posting.
A gyro in 'space' would only be useful for showing you your orientation relative to the surface of THE EARTH (if it worked at all). It cannot be used to orient a craft relative to the surface of a body it is not first oriented in relation to (i.e. - 'caged'). So how does an astronaut use it to orient himself to a surface - planet, asteroid, or moon - that he has not yet touched down on? "LEVEL" . . . would be level to the surface you took off from; not level to the surface you are approaching. These explanations are classic examples of getting you to only consider what they want you to consider; and to never think of the things that they *_don't want_* you to think of. Ooooh, oooh, look at the dials! Look at all the blinking lights. .
umm no idea who they are or what i am not supposed to think about but the point you make about "It cannot be used to orient a craft relative to the surface of a body it is not first oriented in relation to (i.e. - 'caged')", you know this as a fact from actual work you have done and researched ?
@@mephi654 Absolutely false. "LEVEL" would _not_ be the surface from which you took off. It _would_ be the surface found by finding a vector perpendicular to a line between the gyroscope the source of gravity operating on said gyroscope at *any given time*. This, of course, will flux as one traverses the sphere of the earth's surface. The "LEVEL" which one took off from would almost certainly be different unless the pilot was flying directly above his take off position when he cages his gyro. And FYI, "Caging" a gyro is forcing the gimbals to reorient to the current gravitational pull. I suggest that you have a word with a pilot, they are not that uncommon. Ray

You said: ""Caging" a gyro is forcing the gimbals to reorient to the current gravitational pull." The point I am trying to get across to you is the uselessness of a gyro that hasn't been oriented to the surface of the body you are trying to land on (i.e. - the moon). The LEM is going to come into contact with that surface on legs not wheels. The visibility of that landing site is limited. You can't be trusting your life instruments giving correct readings of the craft's orientation to Florida! @@raymroz5806
you said you use gyroscopes to control the attitude?? I understand you could control the rotation or orientation of the spacecraft with the gyros but, how could you affect to the linear momentum(to control attitude) just with gyros? Thanks and hello from Spain:)
Maybe you are confusing attitude with altitude. Yo también soy de España, "attitude" viene a traducirse a "control en los tres ejes", no a altura o translación.
Yes. Because a gyroscope aligns its axis to a fixed direction in space, and the ISS is orbiting once every 90 minutes. The ISS has a synchronous rotation with its line of sight to Earth, such that it makes the same face toward Earth, just like the moon makes the same face toward us as well. So the gyroscopes will drift, and this needs to be accounted for when using the gyroscopes as a direction reference.
@@IgotQuestions. That's what a gyroscope without correction would do. I don't know what they do to compensate for the 4 degree per minute drift on their actual gyroscopes that they use for spacecraft guidance. There could be a circuit with a timer that compensates for it, or that adjusts it to stop it from drifting. I know what they do to correct for the drift of aircraft gyroscopes, but that wouldn't work on the ISS without a gravitational field to reference.
By using gyroscopes with angler momentum. NASA should be able to use those gyroscopes & converted it to mechanical resistance. Then by using mechanical linear oscillation on the x-axis with the Magcore1. It can be used for propulsion at zero/microgravity. For the exploration for space. Quote: (Accelerated kinetic force will displace mass of resistance. Even at zero/microgravity) Hooke vs Newton.
Nice Presentation from ISS. Really helpful to understand '0' gravity environment and how gyro's angular momentum helps to stabilise the ISS in the position we need.
4:03 How are his glasses staying on his face? Did they glue them on or something? Shouldn't they float off his face because of the momentum (like everything else in the ISS, apparently) in a weightless environment? I have glasses and they fly off my face if I move my head too fast, so why doesn't it happen here? They stay firmly cemented on his noggin like they should on the ground.
The ISS is close enough to the earth to experience only the 'y' force gravity component, so the gyro will always stay vertical to the plain of the earth. However since they tell us that space is weightless, then there is no 'y' component. This is totally confusing. Is space weightless or is this filmed on the earth?
ISS is in orbit around Earth, this is effectively what things would look like in the absence of any gravitational field. Gyro is always pointed towards earth because the ISS is effectively "spinning" at the same rate as its orbit, like how the same face of the moon is always facing Earth.
He is in the same way weightless as a stone you throw from a mountain and creating a falling arc is weightless. The only difference is, that you are not able to give the stone a lot of speed, while the ISS actually has the speed such that the arc constantly misses ground. But other then that, there is not much difference between what is going on inside the stone and what is going on inside ISS. Both are falling in an arc and are weightless while still under the influence of gravity. It is gravity which makes the stone curve down AND makes the ISS curve down. The faster the stone goes the farther away from you it will hit the ground. The ISS goes fast enough, that the curvature of the earth will make the ground turn away from the ISS in the same way as the falling path of ISS curves to the ground.
Spin velocity is a perpendicular vector to the tilting seesaw end velocities of the plane, and this tilting end velocity switches ends twice per rotation, instantaneously resolved to acceleration at the tilt axis. Perpendicular vectors DO NOT affect each other, so tangential spin velocity is NOT affect by tangential tilt velocity. Math has people thinking that rules and laws are causal.

What is the GYRO pulling against since there is no fuel exiting the station, what happens to Newtons third law of equal and opposite reaction ??? Looks like angler momentum is the term used to describe the hooks that the GYROS will pull against to change the station position. So Newtonian 3 law does NOT apply here... Wow... what "they" can't explain is what the GYROS pull against in empty space vacuum.. Maybe It's invisible and not seen by humans as the Earth hurls through space at 66,000 miles through space.. Like one driving a car at 60 MPH with the windows shut, not knowing that the air pressure pushing against the car is there, you only have to crack open the window a little to feel the force... However in space there is no air just something that is there because GYROS interact with this invisible force to pull against it to re-orient the space station. Why is it So.. !!! Al...
Correct. COnservation of angular momentum is the key. The rotating part turns one way, the driving part (the rotating part does not spin on its own) rotates in the other direction. Experiment: get a motor, as used eg. in model cars. Hold it in your hand. When powering up the motor you can feel, that the motor housing wants to rotate in the opposite direction then the rotor. The same in the opposite direction: when slowing down the motor, you can feel that the housing again wants to rotate in the opposite direction of the rotational change. So to control the attitude all you need is in principle a motor which rotates a heavy mass. Whenever you need to rotate in one direction you make this motor change rotational speed in the opposite direction. That is why those things usually are called "reaction wheels" and not gyro. But of course, every rotating mass is also a gyro.
What's with the ball of Earth on the celing? Why would you bring that in space? His necklace is "floating" and bumping his throat, but its like its not there. That would be annoying and most people would try and fix it constantly. Yes he could be used to it, but seems like it would be more dangerous to wear it. Gives you all the illusion that he is legit though! Nobody looks at the ridiculous things they do in these videos to make people believe its real!
bc the "real gyroscopes" (the toy you see is a real gyroscope) are in operation keeping the ISS stable, sealed in a vacuum chamber to minimize energy lost due to friction. They're also a lot heavier and attached to the ISS, so to demonstrate anything with them he would have to apply an external force on the ISS, which would be quite difficult considering its mass.
they would have to take apart the "Zvezda" module to even show the housing of the gyro's, because they aren't easily accessible by the crew. the gyro's aren't used much, because as you know there is pretty much no friction in space, so the ISS just rotates at a certain rate to keep parallel to the earth, it doesn't need to use much energy to keep it in that constant rotation; it just has to correct over long periods of time for any deviations due to perturbing forces.
How can gyroscopes be used to keep the ISS parallel to the Earth while the gyscopes maintain there axis in relation to space and not to the surface of the Earth?
imagine you have 3 gyroscopes attached to each other, all pointing in their own X, Y, Z direction, 90 degree's from each other. you start off with all of them stationary, not spinning. if you start spinning any of them, the entire system will rotate in the opposite direction along the axis of the gyroscope that's rotating. you can start rotating other gyroscopes, to get different effects, based on how fast each gyro is rotating, they're just torque vector components that add up to a net torque on the system. So basically on the ISS, all three of the gyro's work together, using math, slowing down and speeding up as the spacecraft orbits. it's actually a lot more complicated, you can do many things with gyro's by applying external forces to them (research helicopter's and gyrocopters, to start).
Indeed. I can't remember specifics but I think I've seen evidence of theism in quite a few astronauts. As for cosmonauts, I was watching one of their spherical (AKA "360") videos the other day and I'm pretty sure I saw a picture of the Virgin Mary stuck to the wall in the Russian segment of the ISS!

Could you use strikes of electricity on a free floating gyro to rotate it and to keep it stable. I ask this, with the thought that an electrical Arc has a pushing force.
Cool video.
Im curious if both times downward force was inadvertently applied to the control gyro since it tried to go downwards both times .
Do gyros precess in the ISS as on earth? I observe in the video that it has rigidity. If it does not precess like on earth, then you can prove that you are in space AND also determine how far you are from earth, by judging from the rate of precession corresponding to the velocity of spin of the gyro.
wow so not many comments, this video needs more views,
this is the most interesting thing i ever seen
What about static electricity experiment push pull process? :)
One of the few videos tsken from soace I've ever watched. And the first one used to demonstrate a principle in that way.

The two videos: "Gyroscopes/Angular Momentum"; assisted a lot with understanding these concepts in my Physics course.
Appreciate the video from almost 10 years ago. :)
So if you pull the string and it starts spinning, would it ever stop spinning, if there's not gravity to cause friction to slow it down?
So, Does the ISS always mantain the same "face" towards the earth? or the orientation changes depending on the needs?
Julen PadronesLi It maintains the same orientation
is the orientation of the gyroscope stable relative to the direction of down or relative to its initial orientation?
in other words if an ideal gyro were spun up on the ISS and could run indefinitely would it appear to rotate relative to the orientation of the ISS?
Yes, (depending on the gyro's axis of rotation) an ideal gyro would appear to rotate relative to the ISS.
not sure about this one, i don't see why the gyro should rotate relative to the iss. It just rotate relative to his initial axis of rotation no ?
The ISS keeps the same side of the station pointed towards Earth all the time. This means the ISS rotates once per orbit. I think the gyro would require an outside force to make it rotate with the ISS.
