Let me ask you a question. If we could bore a Tunnel through the EARTH, and you fell through that tunnel, what would be your motion? :D ruclips.net/video/GMgFkqzpRWQ/видео.html
Provided you are a superhuman who can survive absurd pressure, heat, toxicity, 1) With air - You shoot towards the center reaching terminal velocity around 200kmh-1, take weeks to reach center. The center of earth is super dense air but shoot past it. reach a certain distance only to get slowed due to air and gravity now opposite. Do this few times past the core and eventually stop at he core 2) considering no air...-Reach the center in under a hour or few (no more pesky friction). Shoot past the center, get slowed down by gravity gradually (and because no friction) and come out at the other side in 0 velocity...
And not only tunnel through diameter of earth if u dig any tunnel through any random chord of earth then still the particle after entering it will perform SHM
If tunnel exist then the motion oscillatory motion due to potential but at centre we gain K.E so will go next side & again towards to centre in that ideal tunnel with no friction
The best thorough explanation I have ever seen for the topic. I am sure, as time passed by, this video will have million of views. Very well done; the presenter has the quality of an excellent educator. Thank you for making this video. I am going to share it with my students.
Thank you so so so so so so much brother. I honestly can't believe I'm watching this for free, I should be paying for this lol. We need more channels like yours and people like you, genuinely from the bottom of my heart thanks
6:39 how could you take these vector equation to scale differential equation? even if it is for one dimension,still there are two possible directions(positive and negative). I think there will be 3 possible equations, these are 1) my^(••)+by^(•)+ky=0 2)my^(••)- by^(•)+ky=0, ifb>k 3)my^(••)+by^(•)- ky=0, if b
29:43 sir have you taken out x from derivative and how are you doing this multiplying single derivative and making it a single double derivative i can not understand it
i m in 11th rn prep. for jee came here cause my teacher told me to learn the damped ocillation result now i have done diff equations and intern learnt differentiation to get the concept clearly and ig i'll be doing bsc now thanku
Wonderful . Been following your lectures on particle physics. Really helped me in BSc. Can you please describe about your teaching setup. Might be helpful to a lot of tuitors.
Sir damped oscillator has smaller frequency than damped. But at the end of video where you are showing all graphs you are taking same frequency of both
From FBD, ma + bv + kx = 0, then you have taken this equation as scalar but these are vectors and according to sign the equation will change and eventually the solution also.please sir clarify my doubt . This case for velocity and displacement in one direction but , this not valid through out one period of oscillation
is there an intuitive understanding of why the frequency is lower in scenario 2? Dissipation leads to amplitude decaying down but why not the HO coukld still have the same frequency?
at 24:05 phase theta is not equal to zero in the underdamped solution with initial conditions x(0)>0 and v(0)=0, theta is arctg(-beta/omega1) ....also x(0) is not equal to A...calculate A and theta with these initial conditions and see for your self... you should get A=x(0)*omega0/omega1 where omega0 is undamped frequency...
Sir why did you solve the initial differential equation again in critical damping scenario? Since beta and Wo are constants why should their values matter and why can't we plug them into the initially solved equation in the critical damping scenario?

people do not understand how valuable this video is I swear
I do
Why do you think you're the only one who can understand the value of this video?
Ikr
Words cant express the value of this lecture. It can boost your confidence in the very first chapter of engineering physics.
The best thorough explanation I have ever seen for the topic. I am sure, as time passed by, this video will have million of views. Very well done; the presenter has the quality of an excellent educator.
Thank you for making this video. I am going to share it with my students.
It's that DAMNED harmonic oscillator again
this man genuinely smiles during the lecture..his true passion is physics only!!!!!
Thank you so so so so so so much brother. I honestly can't believe I'm watching this for free, I should be paying for this lol. We need more channels like yours and people like you, genuinely from the bottom of my heart thanks
Sir, totally nailed it, best video i ever found on youtube on damped oscillation
@@arpitbarthwal3673 are you asking me or sir?
Loved every single second of this video sir, so much concepts to learn just loved this video
6:39 how could you take these vector equation to scale differential equation? even if it is for one dimension,still there are two possible directions(positive and negative). I think there will be 3 possible equations, these are
1) my^(••)+by^(•)+ky=0
2)my^(••)- by^(•)+ky=0, ifb>k
3)my^(••)+by^(•)- ky=0, if b
wow just wow. ur a really patient teacher and dont rush anything. love your teaching.
Nice teaching style ❤❤❤ parallel universe 🙏🙏🙏
Radhe Radhe
Best channel ever for physics exam ke 2 hrs pehel mila 😂👍
very helpful video, you should keep on making a whole playlist of oscillations and waves
you are fantastic you are best teacher I ever had. thank you very much and this would repeat like simple harmonic oscillation without rest
thankyou so much sir it helped me a lot
Sir you have explained everything very patiently and easy to understand way , you got a new student and a new subscriber
Top level explanation🙏
Honestly you deserve an award
i think iit student will watch your video to pass the exams
29:43 sir have you taken out x from derivative and how are you doing this multiplying single derivative and making it a single double derivative i can not understand it
What a teacher you are!!
Great Sir!! Great!! 🙏🙏
this vid needs more upvotes
It is very helpful video. I understood every concept of this topic.
You are an absolute gem
Best explain i ever seeeeeennnn❤❤
maja a geya!! best class on yt in this topic
I couldn't find any good explanation.. thanks for your work
pure quality, pefection, better teaching method than iit prof
Wonderful explanation ❤
i m in 11th rn prep. for jee came here cause my teacher told me to learn the damped ocillation result now i have done diff equations and intern learnt differentiation to get the concept clearly and ig i'll be doing bsc now thanku

this video help me for studying physics, btw i am a physics student and right now i need a lot of videos with good concepts
Awesome video, understood everything!!!
The way he is explaining is excellent 👌 ❤
lecture itna achha hai ki man karta hai roz comment kru
Thanks alot🙏
Very interesting class😊
sir found your high budget copy in NIT Calicut(Mr.KANAGANATH,BE,ME,PHD)
you just saved me broh...thanks a lot
You earn one subscriber dear professor ❤

Thank you very much sir 😊
Thank you so much sir 💕💕💕
Very very helpful sir. Khub bhalo hoyeche
Thank you sir for uploading frequently
Masterpiece ❤
Best Video ever
Sir, the classes are very good.
Outstanding 😍
Wonderful lecture . Enjoyed it a lot❤
Very good lecture Sir 🙏🙏🙏🙏
Really great teacher 😃😃🥰
Masterpiece!
is there an intuitive understanding of why the frequency is lower in scenario 2? Dissipation leads to amplitude decaying down but why not the HO coukld still have the same frequency?
Understood each words u said thank u sir
The best teacher, thank you
Sir plz tell me about particular solution
It was very useful ❤❤❤❤
But i didnt understand critical damping case , the steps of getting the solution
can someone please explain how he got the general solution at 9:31? meaning why is it added together?
For any linear homogeneous differential equation the linear combination of any two solutions is again a solution.
Sir start a series of lectures.
Excellent explaination!
Best lecture
@For the Love of Physics - Sir, Could you please make a detailed video on Eddy current testing and its Applications
Great explanation sir thank you very much
superb sir
Wonderful✨😍
Very nicely explained.
Hindi medium potential students really need this video learning ….try to start Hindi version too
Nice explanation sir...tq
you saved my day
Thank you so much sirrrr!!!
Watching this for the love of physics
Can you please tell me the name of the simulation app you are using. I need it for my Math Exploration
Thank you
best explanation ❤❤
sir thanks for this video but i am unable to understand the derivation in critical damping condition so can you please make me understand
Sir is it your hand writing or some font of this writing pad ?
at 24:05 phase theta is not equal to zero in the underdamped solution with initial conditions x(0)>0 and v(0)=0, theta is arctg(-beta/omega1) ....also x(0) is not equal to A...calculate A and theta with these initial conditions and see for your self... you should get A=x(0)*omega0/omega1 where omega0 is undamped frequency...
Right bro
Preparing for my MID YEAR JUNE EXAM, 2nd year in COLLEGE PHYSICS
Outstanding sir
Sir can you please make another video on average power supplied to a forced oscillator by an external driving force
Thanks sir
Always best.. 🙏✨
Iam realising that I biharded total topic in my 12th now I am understanding the topic
Love it sir
best of the best keep it on
Thanks sir 😊🙏🙏
NYC sirji
Thank you very much
for critical damping why D.E. is considered, but not the solution. Is there any specific reason
Just wow
fantastic
Sir why did you solve the initial differential equation again in critical damping scenario? Since beta and Wo are constants why should their values matter and why can't we plug them into the initially solved equation in the critical damping scenario?
Great sir
Very good. My only complaint is how your mouth seems far from the microphone, so when the video ends and the ad plays, the ad is so loud.
I will try to rectify that in future videos by normalising the volume to appropriate levels
@@FortheLoveofPhysics Thank you!
sir how this kind of solution is supposed Ae^at?
