The choice of the symbol L to represent angular momentum in physics comes from historical conventions and mathematical convenience. Here are a few reasons why L is commonly used to represent angular momentum: Consistency with Linear Momentum: In many physics textbooks and courses, linear momentum is denoted by p. Using a different letter for angular momentum helps to distinguish it from linear momentum. The letter L was likely chosen to maintain consistency with the letter p, as it is a prominent letter in the Latin alphabet. Connection to the Term "Angular": The letter L may be chosen to represent angular momentum because it resembles the shape of a spinning object. When you think of an object rotating or spinning, it often forms a circular or angular shape, which aligns with the use of the letter L to represent angular momentum. Mathematical Convenience: In mathematical equations and formulas, L is a convenient letter to use because it is clear and easy to distinguish from other symbols. It also doesn't have any specific meaning attached to it, allowing it to be used in various contexts related to angular momentum without confusion.
it took me so much time to find a video/ explaination in such a easy language. Thank u soo much for this amazing video I am still in middle school but this video explained the whole topic very easily
Hello Organic Chemistry Tutor!! My friends and I love your videos, they are amazing and helpful. We were wondering if you can do Multi-variable Calculus videos and Differential Equations? Please take this into consideration. I know a lot of people who will definitely watch!!
All your videos are excellent, and exceedingly valuable. Its quite well organised , perfect synchronisation. Your complete work is after through carefull studies and research. I feel great to appreciate you. Wish you a long healthy life ,and for the prosperity. Linear momentum is universally represented by "P", isnt it?, P=mv. Hope its not rhow" greek symbol..
Can you explain the most efficient way to swing a golf club fast? For a right handed player, is it correct to consider the left shoulder as the center of a circle? Then… the left arm and club shaft as the radius of that circle? Finally, is the club head itself that thing that should be considered on the perimeter of that circle that has to be moved fast? Thank you for your consideration.
Excellent efforts...great video...but one question..can we replace w( omega) by just V/R ...V is a quantity ( velocity) from linear velocity ,say V =ds/dt...., but omega (w) = d(theta)/dt...isn't it? \omega=\frac{\Delta \theta}{\Delta t} {\omega} = angular velocity {\Delta \theta} = change in angular rotation {\Delta t} = change in time
Hey would you mind doing a video like this on rotational dynamics? I know you've made a video a while back on it (I've watched it) but I'm still a bit confused
if you decrease the mass instead of decreasing the radius, it wouldn't be conservation of angular momentum, would it? like if I'm on a spinning chair with hands outstretched, holding 2 masses in my hands. If I drop the 2 masses while spinning, my angular velocity should stay the same, right? since the 2 masses take away some of the momentum while dropping the masses, and no net torque was actually acting on me spinning
Just to let you know, angular energy is conserved, not angular momentum. Your derivation of COAM makes the assumption that I is constant which is not the case for a variable radii system. www.baur-research.com/Physics
The example of a figure skater pulling his/her arms in is an example of reducing radius/I…hence the increase in angular velocity. Angular momentum by definition is conserved
@@rodneyramcharitar2300 Nonsense. Something cannot be "conserved by definition". Especially when it is not conserved in reality. A figure skater "spins faster" because angular energy is conserved and if you measure her, you will find this to be the case and that she is far too slow to be conserving angular momentum and actually disproves conservation of angular momentum.
@@rodneyramcharitar2300 This man has an agenda to spread misinformation. He did an experiment where he pulled in a spinning object by a string through a tube and found that the results were inconsistent with what conservation of angular momentum would predict. The reason is friction and drag apply external torques to the system, along with unintentional torques that his other hand applied to the system, which is why it didn't get to the speed that conservation of angular momentum would predict. He thinks it is kinetic energy that is conserved instead of angular momentum, but refuses to accept that there is work done on a rotating system to redistribute its mass closer to the center, which would explain why kinetic energy can increase. There are experiments that do a better job of controlling for external torques by moving two masses together to avoid imbalance, and reducing the influences of outside torques, and the results are consistent with conservation of angular momentum.

The use of "L" for angular momentum actually stems from the Latin term "impetus laevis," meaning "smooth tendency to motion."
Thank You
You were meant to be a teacher , you r always best
my man got way more qualifications than johnny sins himself as a jack of all trades lmao
it took me so much time to find a video/ explaination in such a easy language. Thank u soo much for this amazing video

Brother.. u teach better than my teacher
ibrahim abulssa so true... This guy is the only reason I'm going to pass maths this year!
Agreed.
@@cookielyon3937 😂😂👍 same situation
Thank you words alone can't express my appretiation
I love your videos. I finally understand various forms of mathematics and scientific definitions because of these videos. Thanks
U r the best physics teacher ever!!!!!!
Thank you! Finals are next week and this was what I really needed help on. Your videos are great!
i hope you did well
Same. Probably gonna fail
best easy explanation after watching so many videos
Thank you so much for your videos. Your videos have helped me through Calculus, Physics, and Chemistry thus far! 😃
This is the best explanation of momentum, tysm!

Thqmk you very very much. The best ever explanation of angular momentum🤗
Thank you so much, I watched the video once and instantly knew I had to take notes. Super helpful?
How well you explained it... Thanks
your voice soothing fr
So that's why neutron stars spin so fast? Because the star size decreases and they obey conservation of angular momentum and spin faster
Brooooooo.... that was absolutely GREAT.
Thank U very much
This is certainly helpful

Thanks a lot! Much clearer than khan's video! a lot more logical and reasonable
Excellent efforts...great video...but one question..can we replace w( omega) by just V/R ...V is a quantity ( velocity) from linear velocity ,say V =ds/dt...., but omega (w) = d(theta)/dt...isn't it?
\omega=\frac{\Delta \theta}{\Delta t}
{\omega} = angular velocity
{\Delta \theta} = change in angular rotation
{\Delta t} = change in time
Thank you dear, your lectures are a blessing for me
just the perfect breadth for me, got everything covered! xD
thanks sooo much understood on angular momentum so weeeelll💯💯💯💯God bless 💯
Very well explained. Thank you
Amazing physics video ever
Good explanation.
Hey would you mind doing a video like this on rotational dynamics? I know you've made a video a while back on it (I've watched it) but I'm still a bit confused
Nice class thanks teacher
Could you make a video on Zwitterions?
I just learnt a 3 hour class in 15 minutes.
Great explanation, thank you very much
you are a hero
Good lecture!
Thanks bro you just save me
When we change others' angular values to linear we divide by R( like W=V/R, alpha = a/R..... )but here we multiply by R (PxR)and why is that?
Why does angular momentum of chemical elements only have discrete full integer values l = 0, 1, 2, 3 etc. (quantized, not continuous)?
I can’t thank you enough 👏🏻💐
What is the name of the program which he is using to write ?
It's all in this video:

Hey Can you recommend which Alkene & Alkyne video's I should start from.... for beginner level?
Sure.

Alkyne Reactions:
ruclips.net/video/adNW-WRXMHc/видео.html
11:57 but when we drop a mass onto it then its weight mg acts right? So there is an external torque right
Does the formula "L = m.v.r" works if I have a disk rotating around it self?
I have an exam today over this (:
same, hope you did well
He is a divine spirit, who came down to earth to save miserable students like me.
I swear I watched a video about angular momentum on your channel yesterday.
OK.......?
Good, but i think it will be if you try to make the ideas clear with examples and real life situation not only by calculational proofs .....
As iʼm uzbek itʼs perfect pronunciation for me thank you
Video on matrix properties
You're the goat
Do you have any cross product videos?
Thank you so much 🥰
Thanks 💙💙
Literally like a robot to remember all this 😅😅😊
Hey man..can you please post a video about the Leibnitz theorem for nth derivative..
L is an angle 😊
for the algorithm
1:54 In my mind L for a right angle not official or anything.
Hey dude! I kept on asking you whether you are planing to create video on probability dice problems or not. But I think you never read my comment.
