Hope you will have many more viewers, I will continue to support this channel even after my JEE being a physics lover.
This video is really in a league of its own. The fundamentals of rotation pseudo forces have been explained in such detail that everything can be understood by a normal student. You sir are a gem of a physics teacher. Many can understand what you are trying to teach, but only a few can make it understand in such an easy manner.
i have seen a very high hard work in changing colors of font to make student feel comfortable in understanding,and sir you did your level really the best.
I pray for your long-life sir. Such beautiful, top-notch content being delivered with such passion (I could fully feel it in your voice) for free on this platform is simply unbelievable. Thankyou so very much sir

First of all thanks for such an explanation, really an eye opener concept...always misunderstood by most of us.... I have one doubt sir...while proving the theorem in mathematics part (time 8:27 to 10:23 ) you have used a subscript with Euler part of angular acceleration, Alpha of (A) i.e; angular acceleration of A ......I think angular acceleration (alpha) used in Euler part will be of rotating frame but not of the object being observed... Am I right sir or I have made mistake somewhere ?
Yes , you are right 👍🏼🙂. That was typo at 10:00 on my part. In the previous step , I just wrote alpha without subscript. But from next step, upon multiplication of mA term , somehow, I wrote alpha A , and kept carrying it in further steps without any use. Yes alpha and Omega are of the rotating frame itself 🙂👍🏼. Thank you for pointing out 🙏.

" What I'm trying to understand is that: (1) If we are analyzing the situation using polar coordinate system, then if r and theta both are changing, then Coriolis acceleration that acts (which by the way is real according to Kleppner and Kolenkow), is this Coriolis acceleration different from the Coriolis acceleration that would come into play due to Coriolis force, if we analyze the same situation from a rotating frame of reference ? (2) Can Coriolis acceleration (real one) and Coriolis acceleration (due to Coriolis force when seen from rotating frame of reference) act simultaneously at a moving body(whose r and theta both are changing with time), if we observe from a rotating frame of reference using polar coordinate system ? I request you to kindly make a video explaining this, or atleast write your answer as comment here..
dude read the book more clearly , in the book it says that in rotating frame(which perhaps isnt our reference frame or laboratory frame) coriolis force acting isnt real but in the kinematics section .. the paragraph you read particle has some speed , accn , initial position etc , so we are interpreting the equation of motion in polar coordinates that is .. for some accn in cartesian coordinate we break the components of accn in polar coordinates and we get the expression as shown in the video for example 2w*r is the accn in tangential or say transverse direction given that omega is constant. in the book ,we are just interpreting motion of particle in polar coordinates. now in circular motion problems , we consider that the body is moving in some way in our laboratory system , but in the frame of the rotating body the other body let say some other omega relative to itself and then we use the help of polar coordinates to find that relative accn or velocity.hence in the first case the sh*t is real to us but in second case the sh*t is pseudo

After watching this video, I am excited to see that atleast someone has mentioned the same concept in a very simple manner.
Sir @20:00 can u pls tell how centrifugal force is in horizontal direction i am confused coz in formula, it was -ma wx(wxrab) but rab is not horizontal since the object is behind the line of sight of obeserver then how horzontal force can act
At 7:25 I have difficulty in understanding the 3rd step .... we wrote differentiation of (Vab)r , of the 2 terms the first one should be differentiation of rotating vector (Vab)r in rotating frame , however is differentiation of (Vab)r and (Vab)t same ? I know that there will be difference in second term involving omega however would the first term be same . I also had doubt in visualizing (Vab)r as a rotating vector , is it like a tangent going around a circle with centre at observer ?

Sir if the rotating table is itself translating with velocity v , Can we still use the rotating frame in same manner or some other pseudo forces will appear ?
Sir at 28:59 the turn table is moving anticlockwise with omega so you considerd omega to B as outwards. Sir i didnt understand this pls can you explain.
Sir pls clear this small doubt at 5:47 how did u write rate of change of rAB as VA-Vb as length would only change if the velocities are along r vector suppose if velocities are perpendicular to position vector then dr/dt shells be zero but it gives a value how sir?
It's a good doubt 🙂. What you said is right if it was rate of change of MAGNITUDE of rAB , but it was rate of change of vector rAB , then net velocity vectors should be considered and not just the components along rAB
Sir (20:05), you have mentioned that the relative velocity is away from from observer in rotating frame. You have taken vrel as horizontal. Could you please explain it. Why vrel is nt the vector difference between two velocity
Help here sir,in 7:25,you are taking differentiation of Va/b in rotating frame to be equivalent to differentiation of Va/b in translating term, kindly shed light there sir
Sir how to use your channel as a dropper I am enrolled in a coaching and preparing for jee 2022 from scratch and I watched one of your videos and I was shocked how clearly and greatly explain tough concept 😁
So for the last scenario, we saw that stationary person B seemed to be rotating in radius r_2 circle in the frame of the rotating observer. But my question is when both come at a minimum distance, i.e. (r_2 -r_1), then how is it possible for a rotating observer to measure this distance as r_2? Please help me here!
At 26:00 , the OBSERVER A doesn't see B to be rotating in circle with "A" as center . He observes him to be in circle of radius R2 with center at centre of turntable. It's like observing a circular motion from an off-center Point
Sir if a ball is rotating around a string then we say that acceleration of ball is mrw² outward w.r t rotating frame but according to theory discussed in video acceleration of ball w.r.t to rotating body should be F real+F pseudo=-mrw²+mrw²(centrifugal force due to rotation of the centre.then sir why the earlier one is wrong.i am pretty confused.
@@twistedargument4308 then centrifugal force is mrw^2 and linear pseudo force term is zero. But , if observer is at midpoint , then centrifugal force and linear pseudo force term each are mrw^2/2 but total pseudo force is still mrw^2. Pick your observer rigidly attached to any point, the centrifugal and linear pseudo force term individually Change but total pseudo force is Same
Sir pls clear some of my doubts regarding this topic : 1) What is the difference between a translatory frame and rotatory frame can we not have perpendicular velocities in a translatory frame if yes then our line of sight is rotating itself doesn’t it become a rotatory frame ..? How do we differentiate bw the two I am not able to understand this.. does translatory means we can only have velocities along the line of sight .? And lastly if my line of sight is rotating and I’m myself rotating does this means same. .? I need to clear these doubts then only I’ll be able to understand coriolis and other pseudo forces
You can watch the previous resolved video mentioned (check in description) at the start to understand the difference between translating and Rotating frames... If doubt persists you can DM me in my app, I can explain using audio message when I am free, instead of typing message here🙂
Sir in iroovar cone rotation problem you had mentioned da/dt=a x w but here we have done as da/dt = a x w + the normal term we would get by differentiating a where a is rotating vector
In the irodov cone problem , I did not consider a Rotating frame attached to the axis . In this video , during differentiation , I mentioned it was about a Rotating frame

What a nice video sir! Sir I have a doubt if I may ask, shall be really thankful if you would clarify in ur free time. What exactly is relative angular velocity if two objects are moving on concentric circles? Is it (w1-w2) ? or is it (V1-V2)/ (r1-r2) ? {r1,r2 being position vectors} Two of them are giving different answers and a few searches on internet has further confused me a lot.
@@PHYSICSSIRJEE Sir here as points don't rotate u have neglected the Wa term But if it's two people then will it be[ Vrel trans -Wa(distance between them) ]/perpendicular distance between them Here I am initially taking the case when their velocities are parallel And Wa refers angular velocity of frame of reference particle Also what if it's mentioned as particles do we consider them to be points or people
The same concept when I read in David Morin introduction to mechanics there are many things which are misunderstood but now I understood very well thank you sir love from south india
Congratulations sir !! This channel deserves to be seen by EVERY physics lover , physics is such a beautiful subject and with you it becomes even more beautiful !! 😊
KIndly explain the difference between coroilis and centrifugal force physically since both are due to rotation effects i.e. also give examples when is coriolis present and centrifugal absent or vice versa, if any. Also do a full series on topics from basic to advanced level on topic like newtons laws, constraint motion and rotational motion which are the toughest topics.
The points in first paragraph of your comment is completely covered in the long video. Some examples are provided and some more , I will do in a future video Coming to the second paragraph of your comment , it's a very good suggestion 👍🙂. I will definitely take it up in near future. please kindly stay tuned 🙏

@@thermmech4835 relative Omega doesn't work like relative v . It's a pseudo vector. Also relative Omega was not written in the solution. That's why, please Watch, the previous video to this Completely as mentioned in the description to get better clarity.
All the best 👍🙂
What a nice video sir!
Sir I have a doubt if I may ask, shall be really thankful if you would clarify in ur free time.
What exactly is relative angular velocity if two objects are moving on concentric circles? Is it (w1-w2) ?
or is it (V1-V2)/ (r1-r2) ? {r1,r2 being position vectors}
Two of them are giving different answers and a few searches on internet has further confused me a lot.
Neither if two objects are points, it's (Vrel perpendicular to Rrel)/Rrel
@@PHYSICSSIRJEE Ok sir, actually second case was this only , could not frame here in comment correctly.
Thanks a lot sir, I got the clarity now.
@@PHYSICSSIRJEE Sir here as points don't rotate u have neglected the Wa term
But if it's two people then will it be[ Vrel trans -Wa(distance between them) ]/perpendicular distance between them
Here I am initially taking the case when their velocities are parallel
And Wa refers angular velocity of frame of reference particle
Also what if it's mentioned as particles do we consider them to be points or people
Sir aap unaccademy pr aaye ge...!..
The same concept when I read in David Morin introduction to mechanics there are many things which are misunderstood but now I understood very well thank you sir love from south india
Congratulations sir !! This channel deserves to be seen by EVERY physics lover , physics is such a beautiful subject and with you it becomes even more beautiful !! 😊
sir one help sir.., can u please solve Q 1.216 in irodov sir .., I'm really confused with the concept involved sir..,
Please sir .., please
Check step -1 of this Solution. It's on gravitational pressure 👇

Concept of Coriolis Force ...... I dont know why give me a little dizziness
KIndly explain the difference between coroilis and centrifugal force physically since both are due to rotation effects i.e. also give examples when is coriolis present and centrifugal absent or vice versa, if any.
Also do a full series on topics from basic to advanced level on topic like newtons laws, constraint motion and rotational motion which are the toughest topics.
The points in first paragraph of your comment is completely covered in the long video. Some examples are provided and some more , I will do in a future video
Coming to the second paragraph of your comment , it's a very good suggestion 👍🙂. I will definitely take it up in near future. please kindly stay tuned 🙏
Sir hoping for a Collab soon with nitin sir
janardhan sir can u plz tell me the method to find the depth of vertex of a hanging catenary(question given in pathfinder nlm)
@Puspal Paul yaa thank u for telling me i have actually seen it i posted this doubt before sir uploaded that video
Sir i hope you can be eligible for monitisation please do it sir you will get upto 1,64,235.7988 ruppes
I was the hundrenth person to like it
Haha
Cant explain how frustated i was i thought of this frame at my own but was confused that if we dont consider that rotational factor in relative velocity how can we get a fx ,it was literally amazing sir
I am glad you finally cracked it👍🙂
ohh itna types ka pseudo forces hota h kya.... in 8 yrs of teaching i knew that transaltional and coriolisi only
Back from 200 sir 🥳🥳🥳 congrats
Wow
