Prof. Balakrishnan was my physics professor at IIT Madras when I was there getting my engineering degree in the early 80s. Brilliant professor, humble person. I even took a Quantum Mechanics course with him in addition to the engineering physics courses that all undergradsd had to take. I can still remember everything he taught.
Study from any institution, the course is the same, just profs. will vary from institution to institution. At the end it is your effort that will matter most at the end of the day.
Thank you Sir... for Marvellous way of approaching ,Analysing the Physics... I am big Fan of you Sir....We need teacher like you across India .... We r very lucky to hear your lecture ... Thank you so much ....
These lectures are fantastic. The bit on heat and reversibility is particularly interesting. It seems that there lies a connection to the ubiquity of "workless" constraints. One thing I don't completely agree with is that I feel that Newton's formulation handles constraints just as well as Lagrange's once you introduce the concept of virtual work and d'Alembert's principle. The workless constraints disappear from the EOMs just like they do in the Lagrangian.
Now I can say, that I have LEARNED, in a way that I will never forget again. If you want to study, go read books or go to your professor at school, but if you want to LEARN... here you go.
At 15:10, I don't understand why the thing inside the curly brackets should be 0. Since delta q is arbitrary, he says, he makes the thing inside curly brackets 0. What if it (the thing inside curly brackets) is some sinusoidal function (or any odd function) integrated over it's time period, giving 0 as an answer?
Delq is not 0 at all point of phase space trajectory and we see that left hand side is 0 so it implies that of delq is not 0 then the quantity inside curly bracket must be zero since delq is 0 only at t1 and t2
does T-V is taken as lagrangian because of the consequence of work energy theorem? because K2-K1 = INTEGRAL OF (F.ds) along any path from point 1 and 2 which is V2-V1...thus K2-V2 = K1-V1( AN INVARIANT quantity for conservative system)..Whether to minimise that is it taken as LAGRANGIAN??/
Can any one suggest which studey method should be good for study the classical mechanics Share your study method how u remember these complicated terms
Can anybody recommend a textbook to follow along with this course, especially for practice problems? Goldstein (mentioned at MIT OCW) doesn't cover quite the same material, at least till this lecture. Thanks
I was born in America in the early 50s but my Father was from India. He was a terrorist against English rule, arriving here in 1917. I have just discovered your lectures. For some reason I learn so easily from Indian professors. Thank you for teaching me the motion equations.
Strange to hear the words terrorist for the people who resisted the English atrocities/indignity/human abuse which were as devastating in scale as the holocaust if not more. Never heard freedom fighters referred like that before.
It is not correct to imply that Newton’s laws are somehow equivalent to the Lagrangian method. The latter is only when you know the generalized coordinates that respect constraints. Newton’s laws are more general. Lagrangians have to be derived from Newton’s laws for holonomic constraints.
obviously not, the principle of least action is more of a philosophy than a fact of nature, there are many system which follow it but I would assume many wouldn't though they are rarer.

Bitcoin has a myriad of merits in the current online trade setting i started my investment last year with WellingtonTrades a broker that introduced bitcoin to me. It has however proved itself as a great and useful invention and i'm glad and proud to say today that i've accomplished 99% of my goals with bitcoin.
I made a withdrawal of 5btc yesterday too from trading with George Wellington, i also advise traders who are lacking good signals to contact him today.
You have given me confidence in trading i never had before. Thank you for sharing your knowledge Mr Wellington. I wish i had learned this first before looking into Stock market

Prof. Balakrishnan
You get the best teacher of the planet award.
Thanks for your lectures here on youtube.
It is interesting to compare the contents of the lecture with Fermat"s least time principle.
thank you very much!! prof. Balakrishnan is the best professor ever!!
Speechless, excellent ,inspiring and so on
Thank you very much sir and NPTEL

Yeah true, POWV is quite powerful for connected bodies
Its really nice good for physicist great professor and doing a good job.
Also Refer Classical Mechanics by Simon, that is all useful for you guys..
Sir I am very proud of you. You can clearly English that's we can understand.
It goes very well with taylors book
Now I can say, that I have LEARNED, in a way that I will never forget again.

Hello! How to use Lagrange for a thermal system? Thanks
sounds with american accent .high definition video . well mannered professor . well done teaching.
🙏🙏🙏....huge respect sir! Thanks
Wish I could meet sir I would have bowed in front of him to pay respect
Nicely motivated all along the way. Incidentally, did this video begin to chronically buffer for anyone else at around 22:00?
Yes it did..
Excellent proff
what's the difference between arbitrary variations and dynamic variations?Difficult to comprehend
very nice .. its very useful for us .
we are in village area..
thanks sir
thanks nptelhrd
thanks all for this work.

What if it (the thing inside curly brackets) is some sinusoidal function (or any odd function) integrated over it's time period, giving 0 as an answer?
These professors will do anything to prove their final result..no logic there...the important thing is to prove
Silly question
Delq is not 0 at all point of phase space trajectory and we see that left hand side is 0 so it implies that of delq is not 0 then the quantity inside curly bracket must be zero since delq is 0 only at t1 and t2
I thought position q and dq/dt were sufficient for systems with potentials that are only a function of q, position ?
10:16, I think balki's finger was wounded.
Such a great lecture...

Can any one suggest which studey method should be good for study the classical mechanics
Share your study method how u remember these complicated terms

Hello Sir! How to formulate Lagrange for thermal system? Thanks
Can I study Lagrangian Mechanics to boost my performance in jee advanced exam preparation...?
You explained beautifully
Very much helpfull.thanks a lot sir
What a lecture .Remarkable
Which branch includes this subject?
Mechanical Engg.

British rule. Not English
Not a terrorist, freedom struggler

How old are the students sitting here? Which year of college?
beautiful
this video has one problem, the camera moves too much and it makes me dizzy
awesome sir v help full lecture
at last I've found my nightmares' solution.
Can we use langrangian equation to solve each problem of machanic?
same doubt
obviously not, the principle of least action is more of a philosophy than a fact of nature, there are many system which follow it but I would assume many wouldn't though they are rarer.
does anybody know what the song is?
congratulations
Excellent !!
Thank you

hi sir , if delta q is zero then function will be zero , please tell me how it is possible
