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)😂😍
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.
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 😃👍
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..
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 ://
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.
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 😁
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...
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.
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
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???
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?
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.
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!

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.
