@@ARN48411then why did you hear this class?
Wow! This is the best derivation for centripetal acceleration that I found! Thanks!
this proves nothing
Couldn't have said it better!! So well explained and satisfying to watch it just unfold. :)
@@bruh8680 wut your existance
That was a very simple and elegant derivation. Much simpler than the position vector approach that I'm more familiar with. Well done and it took less than 4 minutes.
Thank you so much. I had a hard time understanding the proof they provided in my textbook, and you explained it 30 times better.
Thank you so much. You are the only person to explain this thoroughly enough for me to understand. The book im using said that (delta v) points to the center but didn't explain or show how like you did. Thanks.
Bless u for this
Simplest Derivation In RUclips!
And His *AHKH LENGHT* and *THITA* can be remember so quickly.
@@nikolajancic7130 the grammar Nazis strike again... Chill won't ya it's fine...
@@aadithyahrudhay2269 grammar Nazis lol
lmfao!!!!!
This is the best explaination of the formula I can find. AHKH LENGHT makes it better
@@aadithyahrudhay2269 not even grammar it’s just a pronunciation accent
I am really above moon as I have been struggling to understand this scenario and luckily I came across this site. Huge thanks.
Impressive proof of this formula that most Physics courses don't mention or when they do it takes forever. PERFERCT ! Congratulations
plus the accent makes physics more fun
Thanks sir this explanation clears my all dought about centripetal acceleration keep videos like this for our better study thank you very much sir ☺️☺️
Thank you for your explanation. It makes sense to me and resolves my confusion!
I'm from sri lanka and thank you for sharing.. Well gained
Excellent
Very nice derivation
Easy to understand
Thanks
Lucid,intuitive presentation...thanks a lot bro...
Great video mate.Keep on making more videos like this.Thanks
Shouldn't vectors connect head to tail?
Why is the arc length equal to v * delta t ?
OMGG this was so helpful thanks a lot! Also you have a very cute accent sir!
Bro... thank you so very much ❤️🙏
I would think that the angle between the two Rs has to be (180-theta) instead of theta, Am I right?
Amazing explanation!
Sorry if it is a stupid question, but why aren't the vectors v1 and v2 drawn tip-to-tail?
They are two different methods giving the same answer. If you're doing the "tip-to-tail" method you must remember to flip v1. If you're doing the method I used in this video, you must not flip v1. Draw them out yourself to convince yourself :-)
why is the arc length vdt instead of rdtheta?
It is both. From circular measure consideration, it is rdtheta. From distance=speed x time consideration, it is vdt.
Really helpful ☺
Thank you 😊 very much....
Thanksss
Cool!
Derivation of the formula can be simply done through algebra. F = -m- a = ( -m- v^2)/r; a = v^2/r
you just substituted the answer..
you didn't derive at all
TY
Pw is best
Don't know if he did that on purpose
Tita
This was actually a really simple and easy derivation. Nice. I wish I had payed more attention in my geometry classes. For some reason geometrical derivations are challenging to me. Intuitively I understand what is being done, but I just have trouble with the mathematics itself.
Truely agreed bro
You know it's a good video when UK students are watching before their A Levels. :-) Nice one!
Fantastic derivation, really clear - I used it to teach my students!
Haha, I like the swimming-pool analogy! Btw, arclength = r . d(theta) ;-)
/?
Anybody noticed the $2.05 on the pen ...???
Better than most and to the point geometric derivation using similar triangles. He does equate subtended arc with subtended chord by using limit angle theta which many presenters don't.
Thank you it was a ez way to understand and I have no idea why I am studying this cuz I am a 9th grader but this is 11 th
Who cares!
This is awesome - I finally understand. Thanks for being so clear.
Thankyou so much. I've been searching all over youtube to find a good explanation. You made it. And that was the simplest explanation I've so far founded. Thanks
This derivation is very much amazing and to the point mathematical!!!!!The analogy was lucid and very relatable!!!!!!! Good!!!!
This is absolutely fantastic. After confusing lecture videos, and not following Khan, this was fantastic and succint.
Yay! Do check out my other resources at xmphysics.com
Thank you sir for giving easiest derive
You can also explain it by v times ∆t being the same as displacement ∆d, which is always a straight line and never curvy.
cheating. You cannot equate such triangles because v is not a length. Moreover, if you say v1 = v2 and we call it v, in the same breath you say delta_v exists, Wrong.
i understood everything except the last part of delta V/V
Revise similiarity in triangle
the best video i found in yt about centripetal acceleration
UKHHH LENGTH LMAO LOVE THIS DUDE
Thank you so much for this✨️.. for explaining so clearly and deriving the formula very simply and beautifully🙇♀️
sir can you please explain how the triangle's 3rd side a ∆V cuz ∆V = V2 - V1
This is so simple THANK YOUUUU😭😭😭
I have exams in one more hour and this helps a ton… this is a frequently repeated question
dv and dt not delta.
You are working finite elements.
Good work and thx for effort. 👍
I agree, thank you for being so clear.
Beautiful explanation. And you're not acting smartass.
When v1 and V2 are same how will be delta v ?? It should be zero.....if not why you have considered isosceles triangle ration equal
v1 and v2 are equal in magnitude but different in direction. Because they are different in direction, v1 does not subtract v2 away completely. The difference is delta v, which is represented by the third side of the isosceles triangle.
That was sweet
My teacher complicated things so much lol
Really good! Thank you. A-level Physics teacher, 20 years experience.
a much simpler derivation. Thank you
That's a wonderful explanation!
the ak langth are going to make me remember way better
Thank you for the Video, you are genius😀
very simple and beautiful explanation :)
eyy joji spoon
Very clear and we'll presented. Thank you.
the asian ..... haiyaaa!!! jk! .. love u dude
Good explaination. It tooks me hours to understand. Then after i know about the approximation stuff. Now i understand
Simplest way. But is it correct
If s is straight line why v is not velocity
In 11 th standard books in India mostly this proof is given.But there are many other profs based on calculas and I personally like one using circle cord method.
Thank you, man. Very nicely explained.
Very good video, thanks
Well explained..... 👏👏👏👌👌🙏🙏👍👍
I don't understand why is the angle between v1 & v2 theta ?
At 0:53, he said because v1 is r1 rotated by 90 degrees, and v2 is r2 rotated by 90 degrees. So v1 and v2 form the same angle that r1 and r2 form.
best and easiest method to derive this equation.
thanks bro!
God bless you😢 ,if every one on net was just straight forward like you, world would be a different place 😢😢
tata now that makes sense now....
Beautiful - thank you!
Great video. THanks.
I love the way he says teta...
The point that is usually in question is why should we consider dx=s, or in other words, the arch length is equal to the linear displacement between the final and initial positions.
Thank you
Love from India 🇮🇳
That's all, ta-da. Thank you so much. However, I have a question, are you Malaysian or Singaporean Chinese?
Born in malaysia. Crossed over at 11 years old.
thank you so much, you were the only channel who could explain it in a basic way
Damn that guy's insane!
Really good explanation. I understood everything after this.
Lucid explanation, thank you.
excellent explanation tho
Excellent explanation!
Thank you!
Super raa mamae🎉
How v=r??
This is brilliant, Thank you!
LOVE FROM INDIA SIR
Tq very much. Such a simple explanation and easy to understand.
That was a great explanation. So much better than reading it in a book. Thanks.
Tq brother!
