Conservation of Angular Momentum Introduction and Demonstrations

[@nicksingh1400]

I appreciate your dedication in helping high school students like me learn Physics the right way. Thank you so much, sir.

[@FlippingPhysics]

You are most welcome

[@daner36]

nobody talks about how cool he was in high school.

[@lyrical7683]

Cool

[@kavithagopinathan8741]

This is the sort of students every teacher wants during online class

[@idangabay7045]

i can't believe you don't have over million subs ,this channel is incredible.

[@krishsharma4392]

I was crying because i wasn’t getting this. You saved my life THANK YOU THANK YOU 😊

[@FlippingPhysics]

You are absolutely welcome!

[@noahdangerio9540]

Your section in the video where it explains "Why the demonstration works" helped a lot, seeing the equation work both ways, and angular momentum still being conserved made a lot of sense. Thank you.

[@sagarsingh32112]

You deserve at least a million more subs!

[@FlippingPhysics]

Someday....

[@FlippingPhysics]

Any chance you could help me out by doing what I ask people to do in this video? bit.ly/2y4tOCA It would be a great way to show your appreciation!

[@phenomenalphysics3548]

At least!

[@lyrical7683]

Defenetly

[@rekhagupta8011]

Wowww!!! I am from India...and watched the whole video it was simply awesome!!! You explain the concepts crystal clear👍👍 Remarkable video :) Keep up the good work.. (Also i subscribed to your channel)😂😍

[@FlippingPhysics]

Thank you for all your kind words. 😀

[@thomasfraser9072]

Angular momentum is a compound movement of linear direction equally combined with rotational direction. The perfect example is seen in every professional golfers swing. Other then that I could not do the math to save my life. Cheers 😃👍

[@appleitree]

I think simply to say the amount of oomph I receive when someone slaps me tells me the angular momentum. So does that mean momentum is impact?

[@learningisecstatic9348]

Best teaching and cool diving and cool high school video. 1000 likes for each of them. You are simply the best.

[@FlippingPhysics]

Thank you!!!

[@jangofett5758]

Please keep making videos like this, they make physics so much more interesting.Really appreciate your efforts sir

[@FlippingPhysics]

I will do my best.

[@federicogranato9205]

I m just learning physics and I m loving it because of your way of teaching it!

[@FlippingPhysics]

Happy to hear that!

[@karankadam9373]

Best explaination conservation of angular momentum ever...😍😍

[@FlippingPhysics]

Glad you think so!

[@aniketprasad7700]

I am very confuse with bicycle example if angular movement is a vector it can have direction only in one dimension 8:25 as in your bicycle example the angular movement in to the left side so, my question is how we are able to maintain balance in cycle if the angular movementum point to the left why we don't fall on left side?? I hope that my question make sense...

[@carultch]

Vectors do not have direction in only one dimension. In 3-d space, they have direction in all three dimensions. The fact that angular momentum points to the left is just a convention. It doesn't mean that you should rotate to the left. It indicates the axis of rotation, which is none of the directions of the linear velocities of rotation.

[@gamexter6640]

wow!! this is such an underrated video!! nice explanation

[@FlippingPhysics]

Thanks a lot!

[@frankr2007]

thank you for making this videos, you make me love physics again.

[@FlippingPhysics]

This warms my heart. Thanks!

[@CKatz01]

Awesome videos! You make physics more interesting to study!!

[@asishbauri7433]

Can u make a video on need on Axis of Rotation for defining angular momentum

[@backthen4449]

i failed my angular momentum test just last week. but this video taught me more about it than my teacher ever did in the couple of weeks we were learning about it ://

[@FlippingPhysics]

Glad to help you out. Sorry your teacher is not helping you out as much as you feel you need.

[@FlippingPhysics]

Any chance you could help me out by doing what I ask people to do in this video? bit.ly/2y4tOCA It would be a great way to show your appreciation!

[@haliomar1]

nicely presented

[@andrewjustin256]

Mr. P, may I ask what school you graduated from? As well the university!

[@TheHarshil]

Hey, i just found you channel. And is very impressed by your videos. Should have found it sooner haha

[@FlippingPhysics]

Glad you found me. Tell all your friends so people can find my channel sooner!

[@Broimrightt]

you teaches very well sir and puts so much effort in making one video . you will get so many sub soon if not then hamra hi nuksan hoga ki hm phsics ko feel ni krna chahte..

[@sgtghost141]

Regarding the direction of angular momentum of a system , won't it be different from different points of view?

[@FlippingPhysics]

No, it is not. It is the same as the direction of angular velocity. kzbin.info/www/bejne/e4SrZWmDaZ6KeZI

[@blackace1665]

Nice explanation!!! 👍🏻👍🏻

[@iamtrevor1551]

did anyone notice at 7:05 the moment he touches his desk the above equation shows not equals to sign and its immediately gone when he took his hand off it great attention to detail

[@FlippingPhysics]

Glad someone noticed...

[@stevelongjam7216]

Thanks for the lecture

[@victhebric66]

I learned this without even realizing what it was when it was 7. Our backyard tree swing is where I figured out how it works lol it was just so fun to spin like crazy 😁

[@diy-projects]

great editing

[@johnxina7496]

nice flip bro

[@s-semane]

great job.

[@creativedestroyer7823]

Thanks for the video, appreciate it. :)

[@FlippingPhysics]

You are welcome!

[@CrashUp]

I'm going to use a 10 sec clip to demonstrate it in my videos. Please don't sue me. Please. BTW, have you figured out yet why your views are not growing exponentially? The content is amazing, but the numbers are not reciprocating. I'm facing the same problem here in India. I'm creating content in Hindi Language.

[@FlippingPhysics]

I am glad you like my content, however, I am not okay with you using a 10 second clip of my video is your videos.

[@andrewjustin256]

​@@FlippingPhysics Did you end up suing him, Mr. P?

[@jedits6567]

Great video!

[@FlippingPhysics]

Thanks!

[@doctorsahib8466]

graet Sir thank you sir very much

[@musyyabalam2726]

Flipping in Swimming Pool must have been of great fun, yes Mr P.?

[@Exitiouss]

Thank you!

[@FlippingPhysics]

You are welcome!

[@manisha-dh8cu]

Amazing 😍

[@FlippingPhysics]

Thanks 🤗

[@ikramullah8892]

Thanks alot

[@FlippingPhysics]

You are very welcome.

[@Motorcyclegymnast]

that dive doe

[@esmeom345]

GRACIASSS

[@stephenshettler]

I am really genuinely confused how your videos line up exactly with what we do in class each day???

[@FlippingPhysics]

Sorry, however, It is just happenstance.

[@FlippingPhysics]

Any chance you could help me out by doing what I ask people to do in this video? bit.ly/2y4tOCA It would be a great way to show your appreciation!

[@parthapaul4306]

That's so good

[@FlippingPhysics]

Thanks!

[@sjaoenvf]

couple of years ago? anyway, great video. thank you.

[@Isya97]

Good , feel like in class haha

[@FlippingPhysics]

That is my intent!

[@cyber_bot8013]

i agree with sagar

[@Bunnokazooie]

Those sigmas are ready to chomp up their terms!

[@lsjmartin6220]

this is why mechanics physics is cool, you can prove it unlike electromagnetism😂

[@_flavio_carvalho]

Wow

[@philipjameskennedyonemanba7999]

I hate to remove all doubt that I'm this stupid but (and I hope its true because quadruplet geniuses would be so cool) are you one smart physicist/talented actor.... that is equally cool but I am going nuts trying to find differences in...... you....all???

[@FlippingPhysics]

My hope is that, if you watch this, your doubt will be cleared. flippingphysics.com/making-a-video.html

[@dixienormous6052]

Anybody else cringing at how this guy writes a sigma?

[@ultimateXTRM]

Cool childhood recordings lol

[@FlippingPhysics]

Thanks. Back when I was 16 years old. wow

[@andrewjustin256]

It makes me sentimental to take a trip down memory lane! I'm 17 but one day I won't be...

[@zwijac]

In relation to the conservation of angular momentum: If the Big Bang Theory is true and the universe began with the big bang.... Why do two planets spin backwards?

[@carultch]

The first part of your question is about the big bang theory, the second part of your question is about the formation of the solar system. The formation of the solar system is several steps removed from the big bang theory. That is like asking "if cyanobacteria are responsible for the existence of the first molecules of elemental oxygen in our atmosphere, why can't people smell oxygen?". The origins of life on Earth is several levels removed from the evolution of the human species.

[@raymin5619]

you kept your long hair for a very long time

[@FlippingPhysics]

Yep. And I donate it roughly every 3-4 years.

[@andrewjustin256]

What was the reason of growing them if I may as. What motivated you to do this!

[@kp68420]

I think I love you

[@karo.k.8515]

🙃

[@FlippingPhysics]

😬

[@hansjiang373]

Those were the ugliest summation signs i have ever seen but nice videp

[@Cinchyable]

There's about 97 conservation of angular momentum videos on youtube and this one is maybe the 32nd best one. Not bad, not great... kind of meh

[@Cinchyable]

Nothing personal - but stick to creating content and do production--but get someone else to perform on-screen.

[@TheAnimammal]

Dear Sir, I am sorry to have to be the one to point this out but your demonstration of the swivel chair does not conserve angular momentum. The prediction that "it spins faster" is not a scientific prediction. "it spins faster" is an infantile and negligent prediction. Unfortunately we have been doing this for centuries. A scientific prediction must be evaluated and when we do that, we find that none of the demonstrations and examples conserve angular momentum. Please see example 1: www.baur-research.com/Physics/measure.html. According to Richard Feynman, if the results of experiment differ from the predictions of theory, then the theory is wrong. Irrelevant of who developed it or how many people are convinced by it, the theory is wrong. In other words, the law of conservation of angular momentum is WRONG!

[@dadinggo]

The information in your link is infantile and negligent..... using a a completely made up uncertainty: +/- .2 seconds due to the stop watch? watching a video on a monitor with a refresh-rate, at a certain fps which is further dependent on your system and how the video your watching was filmed and then depending on your eyes and your reaction time to be the measuring device. Yeahhhh well call that +/- .2 sounds good! Id say if you adjust your uncertainty to realistic levels then even your own calculations disprove your point and prove conservation of angular momentum. I expect you to conduct this experiment on your own with effective measuring tools and realistic provable uncertainties and then show us your data and your math! That's actually how science works dude. Good luck.

[@TheAnimammal]

FreedomFighter a frame rate error is negligible when compared to .2 seconds you ignorant moron.

[@kichz.7694]

Thank you. I remember wishing I had something like this con college 📉📈😭💀💀💪🐐⬇️🐐🔥💶⏲💴🗿👍🔥💯🗿💯💯
