Why Does A Spinning Top Lift Itself Up? 

"a pan of ice" probably the weirdest thing i heard in this video

I remember seeing this in a VSauce video. Seeing this here again is a treat as well. Great one TAL

A spinning top is not just a childs toy. in the sense that it helps to have a PhD in physics to figure out how it works. Besides, some adults DO play with spinning tops (check the web), and some make very elegant ones (see). A spinning top is remarkable because it tends to defy gravity while it is spinning. If spun fast enough, a spinning top will rise to a vertical position and happily stay there, despite the fact that it will fall over if it stops spinning. A spinning egg is just as amazing. If a hard-boiled egg is spun fast enough it will rise up and spin on one end. A tippe top does something similar, but is even more spectacular. It turns itself completely upside down and ends up spinning with its peg underneath the sphere that was originally spinning underneath the peg used to spin it. The basic physics behind all these effects is that a torque is required to rotate an object. The torque is equal to the rate of change of angular momentum. There is nothing magic about that. It is the rotational equivalent of what happens when an object accelerates along a straight line. In that case, the force on the object is equal to the rate of change of its momentum. Angular momentum is similar to linear momentum, but it refers to motion in a circular rather than a straight line path. Usually, the torque acting on a spinning top is just due to the weight of the top. If the top is perfectly upright there is no torque acting on it but if it leans sideways then it will tend to fall over due to the torque about the bottom end. It will indeed fall over if it is not spinning. If it is spinning then it does something else. Instead of falling down, it �falls� sideways. That�s the amazing part. The effect is described as precession, and is explained in simple terms below. A spinning top precesses slowly around a vertical axis through its point of support while it spins rapidly about its own axis. The usual �explanation� is that the change in angular momentum must be in the same direction as the torque on the top - that is, in the sideways direction. The spin axis must move sideways instead of down, but that is just stating the observed facts in fancy technical words.

As someone who grew up obsessed with beyblades, for once i knew exactly what is going on right away.

As they say friction , a necessary evil

"This should be weird to you"

FRICTION TENSION + auto balance falling, aka spinning more than 10 times a second.

His explanation is not right. The egg can still rise even on ice and gyroscopes can rise as well thus it is not due to sliding or rolling friction. Check out my MES Experiments videos to see gyros rise on their own.

As the saying goes What spins around goes around

The bird inside the egg be like "The wheels in the bus goes round and round"

“The center of mass of the egg is the center” “Ah yes, the floor here is made out of floor”

Indians are pro at spinning traditional tops, miss my childhood. It is still practiced.

I always learn something new from your channel. This one hit home with me! This one, and the forever spin top too have peaked my interest. Amazing!

Watch some part of it in 0.25 speed he will look like he's drunk

This is alot like how orbits change when thrust is applied perpendicular to the orbital trajectory, 90 degrees ahead and behind will raise or fall depending on thrust direction changing an equatorial orbit all the way upto a polar orbit.

I remember this toy from V-sauce

friendship with Beyblade ended, now Topsy Turvy Top is my new friend.

That's one Interesting Toy! 🤔

"You spin me right round baby right round like a record baby right round round round".

Few years ago, I was wondering if a spinning top can drive itself. It was very wobbly: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZmCAgVtw_DI.html But just as a "proof of concept" it worked. It didn't fall as long the batteries had power. A solar driven one would spin as long it's exposed with light. So it's absolutely possible that a spinning top can drive itself for hours.

At 1:09 I'm guessing it has something to do with angular momentum. Maybe a component points straight down? Edit: well, half correct 😞

When you learn Science and still have fun:

Welcome to another episode of Michael's toys... I mean the Action Lab

Another nice job. Keep them coming brada!

Awesome work my dude 🙂

You spin me right round friction right round Potential energy right round gravity right round

“It’s centre of mass is in the Centre” Ya No shid

the chik in the egg: *screaming*

Hello Action lab buddy I wanted to know experimentally that if boiling point of water increases with increasing atmospheric pressure than What will be its boiling point in vacuum?

My teacher should try like this tutorial... she can go home early to finish her class with 100% student understood and happy with your class 😍☺️

So can we say that the normal reaction is non-uniformly distributed which leads to non-uniform frictional force at different points which produces torque to counter or even outforce the torque due to gravity along the rotation axis. Hence lifting the top.

I've observed this in Beyblade with ball shaped tips (conical tips do sometimes do this as well but they aren't a perfect cone that comes to a defined point usually).

Action Labs: This should be wired yo you because the eggs center of mass is in the the center Me: Ah yes and every 60 seconds in Africa a minute passes Btw the time is at 1:24

You could be the new Mr. Wizard!!

Will you cross upload to lbry/odysee?

Sir can you demonstrate and teach something with gyroscopes please

This is the beybalde and bakugan 𝙒𝙀 𝙉𝙀𝙀𝘿.

I love this channel.

too much fun

Your channel is really giving much more knowledge than any school or school textbooks......... Never Gonna leave your channel, sir.👍

Fun fact this is what they use on warships to keep them stable

Yo dawg, I heard you like tops, so we put a top in the top of yo top

Hi! Here's an idea for a new video! Inspired by the latest Veritasium video. As I was trying to understand how that contraption works if it works at all, I got quite submerged into sailing and wind speeds. So, when I was trying to understand how come that the apparent wind speed is bigger than the real one, if boat travels perpendicular to the real wind, this idea came to my mind. The wind, that blows from the front of the boat, comes from the energy, stored in a kinetic form, of a wind that blew previously. So we can say that it is sort of the "wind from the past". And apparent wind is a sum of the actual and former wind. Simple, but a bit mind blowing concept, if you think about it :D

Really you do what you said "one experiment is worth 1000 expert opinions." Thanks a lot action lab for teaching us in such a wonderful way.

Who else thinks that he looks kinda like Ryan Reynolds?

moment of inertia can be used to explain easily

1:27 hum yes the floor here is made out of floor

I did this with a spaghetti squash the other day and was wondering what the heck was happening!

This is cool. It reminds me of a video on another channel where they describe the force on a charge in a electromagnetic field and how the result is the charge travelling a circular path.

Imagine being an embryo in that egg and you go on a crazy top-spinning experiment. Talk about vertigo.

You’re very fun to watch, sir. Always entertaining and informative. Of all RU-vid channels, you are definitely one of my most consistently enjoyed ones.

There can’t be ✨four✨ people who are first in this comment section

I pretty much watch all your videos. I look forward to them. I love the science and the novelty!

Huh I always thought it was from force of the spin making the opposite side of where it was pushed rise back up (somewhat hard to explain without visual aid). Because of the tilt, the spin would be directed slightly upwards continuing to correct itself with each "throw" until it comes to rest completely upright again. Interesting video glad I know what really causes it now lol. Thanks!

Anyone else think he kinda looks like Peña from Narcos

*Maximum Garuda Intensifies*

I like this man very much

Wait, you can make a 5 plus minutes long video in under a minute? The dark side of physics leads to filming techniques that some consider unnatural.

Nice video, but there’s no atriction between planet Earth and cosmic space, in ways for it keeping inclined its axis, while going around the Sun...😉

You are no less than veritasium

This is how Gyro actually taught Johnny spin

Yea vsause talked about this

As a follow-up, perhaps look at the physics which causes some items to spin stably with their centre of mass as high as it can be. I have a ring, with a stone in a claw setting, whose centre of mass is heavily biased towards the stone. Whatever orientation I initiate a spin from, it always ends up spinning with the stone uppermost.

Does anyone remember playing beyblades in a pan while theres oil the we burn it to make it more fun???

My school is starting this week, but I started learning today 😂

"Wazzzzuuup DingDongers, welcome to 'D!NG'... THE NAME THE CHANNEL HAS ALWAYS GONE BY. IT HAS NEVER BEEN CALLED ANYTHING THAT MIGHT NOT BE CONSIDERED BRAND-FRIENDLY OR MIGHT POSSIBLY LEAD TO DEMONETIZATION."

I actually loved it 🤩👍

same with beyblade's yay

Day 69 of becoming the most subscribed RU-vid channel with zero video’s so I can live the life. 💪🏼🙎🏼‍♂️🤙🏼. Pretty cool

Action Lab SHORTS!?!?! Sheesh... the clothing options are endless.

My favorite video on gyroscopic precession: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-n5bKzBZ7XuM.html If you have 3 minutes you NEED to watch this. It will help you understand it much better.

I'm watching these as youtube gives them to me.......still.......you lost a happy face.

What would happen if the pressure in a horizontal cylindrical tank filled with saturated water at 2.35 bar drops down to 1 bar (opens to atmosphere). I am expecting approximately 4% of the water will turn into vapour which will push the liquid out of the tank. And lot of water (probably far more than 4%) will be expelled out. It will be great to know how much will actually expel out.

Since nobody has commented this The Egg: "This isn't even my final form!!!!"

Isn't it precession?

I already knew the force applied would be at 90 degrees. Because that's what physics teaches you. But I still have not the faintest intuitive clue about WHY.

I saw that on Vsauce

Where's the physics numbers to explain what actually happen to the numbers. Explaining one observation with words not math is still controversial. Learn some basic language skill, common sense and lots of integrity to speak truth about your ignorance.

I don't quite understand the explanation. It seems to me that the linear force (as from the air) has a reaction that is in a common plane (if you push from C the reaction is as if a push came from D, if you push from D the reaction is as if a push came from A, A->B, B->C). But the rotational force seems to have a reaction that is out of the plane and all heading in the same direction (upwards) even though the tangential linear forces are all in different directions. But this can't be from following a "right hand rule" because I imagine the top center of mass moves up regardless of whether you spin it clockwise or counterclockwise. It must be a function of the direction of rotation. As far as the precession, that's not a force in the direction of rotation, is it? So is the friction on the top really doing the inverse of gravity acting on the top? Unless I'm missing something, I think things need to be explained better in the video. What is the correct interpretation of "90 degrees out of phase": how do we determine the proper direction that corresponds to the "phase"?

you just explained the simple physics by which the military has used to operate antigravity craft for decades.

This guy does short videos but smart videos And this toy really really cool 🤩🤩🤩😊😊😊

Gyroscope in action

Beyblade has evovled

That was really interesting, makes sense why is the top would upright itself

Friction definitely plays a major role I don't think that's the only factor tho obviously

if you hold a weight vertically it would seem heavier but when you swing it back and forth the weight becomes lighter because the gravity can't force it because it's Centre of mass is not stable but you would feel the weight's pressure on your shoulder's top. Like this phenomenon so what if we use anti-gravitional force then can we float?

Here's link to an amazing Math video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Q4cw-Nzw3JU.html

hmm, for some reason WE NEED TO FIND OUT THE REASON WHY:P

I'm actually amazed that people like him are on youtube, I mean there's mark rober, veritasium and more, like wow

Can you please tell me where can i buy a toy just like the one you have (Topsy Turvy) . i have been surching the internet i couldn't find anything

Imagine this halpens in the most critical match in beyblade show Audience will be shocked as f

what a coincidence. i was thinking about ding topsy turvy video just before i got reccomended this video

Can we make water artificially by mixing the gases and compressing them?

This channel is also becoming quantity-above-quality channel

Here I thought the top was gonna fly, 'lift up' needs some more specific words.

Hey do you care if people rip off your content on Tiktok without crediting you? @blayzeharter is doing it.

This is actually why actuators on helicopter main rotors are angled 90 degrees from the movement you want to get from them =)

Sir, I want to understand why a rolling wheel can balance vertically and not a stationary wheel? Could you please explain it practically?

This guy has some interesting content, but his nasally, nerdy voice is so unbearable that all I can do is watch 15 seconds and complain about him.

nice flag, our flag, but contra rotating dual spinner, should not wobble around
