This is confusing because there is a discontinuity at :03, and the wheel changes its direction of rotational spin at this discontinuity. The woman is holding the wheel with the suspended/string end toward her both before and after this discontinuity. Before the discontinuity, the wheel spins clockwise from her perspective. After the discontinuity the wheel is spinning counterclockwise from her perspective. Thus, the rotational direction of the wheel reverse at this discontinuity. I was very confused by what I saw after the discontinuity until I figured out the wheel isn't spinning in the direction that I thought it was spinning, and the reason I thought it was spinning the other direction is because it was spinning in the other direction just prior to the discontinuity. Terribly confusing.
Sorry about that! I just took that clip from another video (linked in the description), and didn't even think to check if the source material had a confusing cut in it.
@@TheHuesSciTechstill replying after 6 years? Bloody legend
Student of physics now for 4 years and this is the first explanation that makes sense. Thanks dude. This is actually the way it should be explained.
YOU are wrong, :), this îs NOT an explanation! YOU can not explain what happens here with the conservation laws, to do calculations , yes !
Me too
@@xray4abc913 You seem to have a similar issue with simple punctuation and usage of the English language! Everyone is an expert at something and nobody is an expert at everything.
@@popwatch905 Ha Ha! Very funny! :) Nothing to do with "your hand while it is in precession" !
On a second thought though.....in a funny way...doing the experiment the way I have described it...one has to follow the movement of the bicycle wheel.....and then one could say that the person is ...sort of " precessing"! ;)
What has always amazed me...is the ATTITUDE.....like yours!
I have been describing my ADDITION to a simple experiment shown many times on youtube!
This...addition.......shows a thing NEVER EVER noticed by anyone (at least not to my knowledge!).....and ...then... someone like You ..comes......and observes...nothing.......but the "precession of the hand of the experimenter"....!
Obviously....you are a person that...pays attention......but not enough! You missed a tiny little thing only....
the description of a scientific discovery.......not a huge one, it is true, but nevertheless ....still a discovery!
So, for the sake of a larger audience....the discovery is the following : The wheel can keep a horizontal position only if it has at least a minimal speed of spinning, OR over ! If we increase this speed to even more than this minimal value... the wheel will tilt upward from the horizontal. ( I did do it, make no mistake!). IF we use from the very beginning a higher speed in the horizontal position, which is the starting position HERE ...the wheel of course will keep it until the rotation slows down enough.
If we place the spinning wheel at this tilted upward position...it will precess in it.....and then slowly...as it is losing energy...will get...with its loose end..lower and lower!
The experimenters on youtube, at least the ones that I have seen ......limited themselves to the textbook experiment.
@@xray4abc913 the video illustrated the vectors of the forces. Those are the calculations. All you have to do is stick numbers on them. Make up whatever numbers you want. This is a qualitative explanation, which is first principles.
out of 2034723 videos about how gyroscopes work this one was most concise and delivered the epiphany thank you
Can you help answer this please. When you spin the wheel forward (clockwise) it turns to the left as seen in the video. Spin it backwards (counterclockwise) and it will spin to the right. Here is where I found an issue. Both right and left handed boomerangs are throw forward in a clockwise direction yet the left handed boomerang flies to the right. Why???
I don't think I've ever commented on a UA-cam video ever, until now. This is by far the best, most intuitive explanation I have ever seen or read for this topic. I'm a physics professor and for years had to just tell students "I know it doesn't make intuitive sense at all, you just have to trust the vector math and the equation: torque = dL/dt" because that's always how I learned/understood it. From now on, I'm going to use this explanation for "how this makes sense", instead. (OK but still also tell them they have to trust the equations/math.)
No one in my A level physics class could understand this...at all. I asked the teacher if we could watch this and for some reason it just clicked with everyone. The satellite analogy really is perfect at showing what's going on. Thanks so much!
Awesome!

Because Tha main turn of the boomerang us due to aerodynamics, not to gravity.
The turn due to gravity and momentum is the "leaning upwards" in the fly, later on...
Saludos de 🇨🇱
@@VictorPoulin I'm gonna guess it's aerodynamics/Bernoulli lift due to the different shapes for left/right, but I'll be the left handed one doesn't torque as easily since it works against precession vs addititively (I'm guessing the left handed rang veers to the right and the right veers to the left, due to the lift produced by the shape - ie, which side has the longer path vs shorter straighter path, where the shorter side gets the "lift"). But, since both are rotating "clockwise" or right hand, I'd expect the right handed rang to need less aggressive "lift" from it's shape than the left handed? Have you noticed that the right handed turns more aggressively than an identical but oppositely shaped left handed? Interesting concept. I bet lift is the much strong force on a rang than the precession component of angular momentum from rotational velocity. Anyone with actual knowledge give you any insight on this since you asked (I'm just shootng from the hip late at night insomnia clicking).
@@technobutt2696 I agree that it is lift. You get the same results from a lefty as you would a righty. I agree that precession has little to do with anything going on with the flights. I am friends with many different boomerang builders and most all are learning that precession is what makes the boomerang turn. I am not sure who was the first to tell all of them this but it is now carved in stone for many. Wanted to throw this idea at them about the left handed boomerang but wanted to hear what others thought first. Thank you for your input.

simply and beautifully done.. not hidding behind science and math gargons
this is how good scientists do it.. start form the basics form first principals
I'd you honestly think this was a simple explanation you commonly deal in the esoteric.
@@Krystamyth this is simple at least if you're not a moron
It was Richard Feynman, and he used a 12-year-old so there was just enough vocabulary and patience available to understand, but not enough to swallow unexplained science jargon.

Best video I've seen explaining this. Top notch mate!
I appreciate the feedback!
TheHue's SciTech Dude i have been strugling with this thing for a while and couldnt figure it out and i am not a dumb guy i am pretty familiar with all fields of science and understandes most of the physics videos but not this one and you have made it that much more simple compared to veritasium thank you dude :)
Yes, great vid. I get it now. 600+ h on ksp and never thought of this. Quality.
Absolutely! I can do the math all day, but without being able to understand WHY it was happening I couldn't apply any of the knowledge I had. Once I saw the satellite demo in the video and thought of the resulting vector from the force everything instantly clicked.
Im sory indont see it..i dont get what the teo blue arrows at 1:25 mean..what two axes..i don't find thia intuitive
I am a graduate student that serves as an instructor for a university physics lab. One of our labs is on gyroscopic precession, where the students get to play with a heavy disk with handles (like a bike wheel) spinning very quickly. Watching this video with the recent muscle memory of having the disk spin around my wrist is just incredible - as I watch these animations I physically feel the wheel urge my wrist to spin with the precession. Finally linking mental intuition with a physical sensation, a sensation that previously was to me just an invisible force coming from nowhere, leaves me feeling at ease, and physically resolved, as if a persistent dizziness just cleared up. Thank you so much for making this video; I will most definitely share it with my students, and explain it in class like you did from now on.
I spent the whole day watching veritasium,vsauce,etc to trying to understand the concept. Your presentation really helped to understand the concept . Fortunately i played KSP lol
I've spent DAYS trying to wrap my head around this concept watching video after video and reading everything I could to understand it with no success; that is until your 3 minute video. Now it's so simple to understand! Thank you so much!
@@VictorPoulin Sir, it's because of aerodynamics. When you throw your boomerang with your right hand, the leading edge of your boomerang cuts the wind. Then the top side of your boomerang gets a left push, and the bottom side gets a relative right push. So, it follows a counterclockwise travel path. But when you throw it with your left hand, the trailing edge cuts the wind. So, the top side gets a left push, and the bottom gets a right push, making it travel clockwise.
It's 01:13 at night and I can finally allow myself to sleep. Thank you.
Good explanation and graphics. Concise, clear, simple.
Thanks!
The biggest difficulty was understanding why a moment in one plane would cause motion in another plane. This video really made it easy to visualize the change
A couple years ago I really wanted to wrap my brain around gyroscopic precession, and I watched a bunch of videos about it. Two or three that were quite a bit better than the typical confusing fare combined in my head to give me a good understanding of it. But...I sure as heck wish I had seen this video back then, and FIRST before I watched any others. In 3 minutes you NAILED it. You explained it in the MOST intuitive fashion I've heard yet. EXCELLENT! And thank you!
Outstanding, this has perplexed me for years. As a helicopter pilot it now makes so many aerodynamic effects experienced in a helicopter more explainable.
How did U ever pass an oral ?
I've watched so many videos with the bicycle wheel and just couldn't get a hang of it. Your video was so incredibly well done and as you said, intuitive. Thanks so much!!
This was far more intuitive than anything I've seen so far! Helped me grasp the concept far better!
I've been wondering about this for months and gave up with trying to figure it out, now I finally understand it. Thanks!
As a motorcyclist, I immediately could apply this explanation to the mystery of why leaning a motorcycle causes it to steer in the direction of the lean. My shifted body weight applies a torque pressing the top of the spinning front wheel in the direction of the lean. The wheel responds by precessing in that direction. It now seems so simple. Thanks!
Yah good video. Clear, concise. No frivolous intro, just content. Good job sir! UA-cam needs more of this!
Finally an angular momentum free explanation that is intuitive and makes sense! Thanks so so much
I have been watching almost anything on youtube to understand this concept. None of them worked except this one.Thank You Sir!
That actually makes sense, I just spent a good 10 days looking for an explanation and this is the first thing that has actually made some sense
Best video on youtube for understanding the concept of gyroscope ! Truly genius explanation !
Great intuitive explanation. I performed this experiment at my son's science fair in grade school a few days ago, but only now do I truly understand why it works - and I've watched many videos on the subject. Thank you so much, you really nailed it!
Best video on gyroscopic precession I've seen yet! I now I understand why it occurs and not just how it behaves
Awesome Video/explanation!
Didn't get this for years, yet you managed to explain it in 3 minutes and now it's so simple
I’ve been in aviation for about 4 years now. The concept of Gyroscopic procession applies to the spinning of the prop, as well as conventional vacuum instruments. I have my commercial license and an advanced ground instructor rating, so I’ve listened to explanations on the topic hundreds of times and this is the first time its really made sense. Thank you. Will show this video to my students.
Helped at least 5 of my fellow flight students and myself have that “click” moment, thanks for this video!
This video is amazing. I had enough of the pseudo-explanations given by other channels, this actually make sense. Great work!
At the beginning I was like, "what the??" But then I just kept watching the video over and over and drawing diagrams in my notepad and then using my hand as a plane, and then the idea finally clicked! That was AMAZING...this video is a work of art.
I was laughing at 2:32 because it finally clicked! This was an amazing video, and was just what I was looking for. I knew someone had to do a better job of explaining it, and you did. Thanks!
Great explanation! This is exactly how I started to visualize it when it first clicked for me, but I always struggled to explain that visualization to others. You've shown it perfectly.
Very nice video! My friend Dan has been thinking about this for several years, and immediately understood it after watching this. Needless to say, many nights of sleep has been lost pondering over this problem, but not anymore. Maybe he will show up at school hereon and forth! Thank you.
I searched from the internet for at least 5 hours, still could not understand the gyroscopic precession UNTIL NOW! Thank you!
Your animations are awesome besides the fact that your explanation is exceptional. You clearly took a lot of effort is making this tutorial and people are praising you for it.
I'm one semester away from getting my bachelor's in mechanical engineering and this is the first explanation that made sense to me, even when I'm not in a state to think critically. You made it pretty intuitive to understand and I can definitely see ways to apply this moving forward. Thanks for sharing such a valuable insight!
This was a phenomenal video! That satellite analogy explains this phenomenon in probably the most intuitive I’ve seen. Good on you my friend!
Yes, indeed, by far and away the best explanation that I have so far come across to explain this particular kind of precession. Many thanks.
I can't believe I didn't see this video back then when I was taking Physics in the University. Absolutely brilliant explanation!
You can't imagine how thankful I am. I've been looking for something like this for about an hour
WOW, thank you so much! This explanation is way better AND more accurate than any other I've come across!
This goes to the heart of the difficulty and clears it up. Great job.
That is by far the best explanation I have come across. Thank you.
That's... actually the best explanation I've found yet, and I think I might actually understand it now. Crazy.
best video on youtube explaining this effect, in only 3,5 minutes! great job
Finally an explanation that makes intuitive sense! Great video! Simple and effective.
This is gold. Best, simplest, and most intuitive explanation of precession I've seen. 👏👏👏
I played KSP for some good amount of time to learn about taking spacecraft into orbit and that mechanic you showed there was something that was already familiar to me. I didn't expect that to be the answer to this perplexing physics phenomena for which I didn't have any intuitive explanation until now. Thank you!
Finally! The KSP-style explanation hit the point for me, thank you!
Probably the best explanation of the phenomenon out there. Really good vid.
Oh my god bless your life, you just saved my brain that has been going in circles the past month when I started thinking about this. I FINALLY GET IT
This makes so much more sense than other videos I've seen on the topic!!
This is the very best Gyroscopic precession explanation I've seen. Well done. Thank you!
Thank you! This is a very, very good video. It's short, to the point, perfectly clear, and very informative.
This is the best explanation here, even after 4 freaking years
Oh geez has it been that long :-/
Thanks :-)
Only freaking video which I understanded it .Nice man that made me stop thinking of it as magical.I have been binge watching and reading about gyroscopes but never understanded it until now
Man!!! I never thought I could find such a great explanation!
Most important video out there,keep up the wok
I couldnt understand this phenomena and searched internet documents for weeks but now thanks to you i understand this clearly 👍👍👍
Thank you so much, so many people have thought they understood the concept enough to make a youtube video, and their only explanation is, “the thumb is pointing that way so it makes sense” without actually understanding any of the physics.
Excelent video on the matter , hope to see more like this
Best explanation I've seen yet, very well explained!
Thank you!
Best intuitive explanation about gyroscope I've found. And Kerbal Space Programme! You've earned a sub.
This is amazing, landed here after many videos in this concept, none explained the concept like this
this has to be the best visual explanation on youtube ... thanks man
WOW! ... so happy to find another thinker who chose an intuitive approach to this. I adopted the same 'intuitive' approach to understanding gyroscopic precession 50+ years during my high school physics class. The topic was only skimmed over, but I remember the equations intimidated me. My scenario considered the rim to be comprised of an infinite number of masses forming the disc of the rim but still conceptually independent. When I realized the masses were simply being forced to change their tangential direction by tilting the rim's axis, I was finally able to sleep at night, again. The force (arrows) pushing the balls 'off-course' require an opposite reactive force ... which ends up being the precession.
The sattelite explanation made it a lot more simple. Great work!
master of explanations! wow thanks, i've watched several of these videos but only with YOUR video i was able to understand it completely!!
I've seen many videos explaining principle of gyroscope, this one is the best. Clear and concise. Thank you.
Thank you! This was not clicking in my head until you used the satellite example.
This is the first explanation that I deeply understand! Thanks!
This is the best explanation of gyroscopic forces I've ever seen.
As a physics and engineering student myself (some time ago) I'd say this is the easiest to understand explanation so far. Thanks!
This helped so much for the past year I've been having trouble w this concept thanks!
Was looking for an easier way to teach young aviation students this. Brilliant! Thanks a lot!
This makes so much more sense now. I finally understand gyroscopic precession which I have to know for my pilot instrument rating. Thank you
The video was the best informative then all other videos that I saw earlier. Finally understood the concept
Dude you nailed it. This will stay in my mind forever, congrats and best regards
Explained really well. perhaps the best tutorial video i have seen on Gyroscopic precession.
Other people always give the mathematical explanation (one that with angular momentum and torque vector) which is still doesn't explain much. But your video is totally different, thank you man. You are the only one who made me understand this.
I've seen many videos like this, but this is the greatest!!
You're a physics chiropractor. I've been struggling with this for days and you made it click in three and a half minutes.
Nice, much better than any of those other videos you linked, came from one of them feeling "why did you not explain in detail?" but you sure are able to do that!
You explain so simple it almost sounds wrong, but now that I think about it, there seem to be no mistakes, so I guess that your explanation is correct, amazing
Thank you for making this video! I am a physics major and have been struggling to arrive at an intuitive understanding of gyroscopic precession. Other videos I've seen have explained it using physics principles but didn't address what is actually occurring physically. However, this video provides an explanation that is genuinely intuitive.
This is so much better than all the silly right hand rule, etc., explanations. So many people apply the rules and think they understand the phenomenon. If you can't visualize and explain in words what is happening, you don't understand. Good job. But this is not an intuitive explanation. Intuitive means you can predict an outcome without understanding why. The calculated outcomes are intuitive. This is an analytical explanation.
Great little video, and excellent (if not very fancy-looking) visuals. Thank you!
FINALLY understood gyroscopic precession for good, thank you so much!! The moment you said the satellite doesn't just teleport up when a force is applied it all clicked :D
This was an amazing explanation that finalized my complete understanding of this effect. My amazement started with smarter everyday because of my love of helicopters, to veritasium because I just didn't understand it with smarter everyday, to here. And, although I understood that a torque applied to a rigid body acted 90 degrees out of phase, it was difficult to understand why and your explanation answers that beautifully. Thank you.
You're most welcome, thank you for the generous comment!
now i get it! good guy! this has been keeping me from learning what i actually should learn, for 2 hours. thank you for finally ending this. ;-)
Brilliant. Exactly the explanation I was looking for. I understand the vector explanation but finally a clear intuitive explanation of precession, which also requires some deep thinking to generalize.
Excellent. This does make intuitive sense now. Thank you!
Simple, clear, intuitive, beautifully concise;
Wish more people used the rimless approximation to explain what is going on.
Thanks so much.
Mother of god. I finally get it. Thank you! I needed to understand this in the context of flying an airplane because the propeller is of course a giant gyroscope.
Fantastic work! (I have studied Physics for 4 years at Uni and this is the best explanation I have found).
Thank you sir!! It wasn't until I wacthed this video that I fully understood the concept of gyroscopic procession. You are amazing!
Best video ever to explain this 'weird' motion.
You are simply the best! Awesome! Simply Awesome!
This is the best explanation of precession ever!
Thank you! this is the exact intuitive explanation i was looking for!
