I found this video on the internet of a teacher conducting a wonderful experiment with his students in their classroom.
The experiment was in two phases: one of the students was on the table barefoot and the teacher was applying the force, and the other was when the student was wearing a roller skate on the table and the teacher was applying the force.
In the second case, the student was not feeling any force applied by the teacher and the reason for that was Inertia mentioned in the video but that's WRONG.
NMS sir has explained the complete experiment conducted by the teachers and given the reason for the student not feeling any force.
Questions on such concepts are majorly asked in IIT JEE, Olympiad and many other difficult exams.

@@a.k.gaming5467 inertia is also the one the reason but if you go deep , when you understand about forces then only you can understand how friction helps there in rolling but as i have said in my previous reply . For basics student who don't have much knowledge about mechanics we can say that this happen because of inertia because here also body wants to be in its initial state which is the basics defination of inertia. But if you go for exact reason then nms sir is right .
@vishaldhibar4863 no he is not an advanced level teacher
@a.k.gaming5467 I fully agree with you..
I appreciate these kind of channels who are actually interested in educating students in a right way whereas whole social media is not less than lying.

Great Sir. UA-cam community me Corrective Strategy yaani formula ke development me aage badhne wale aap hi ho
One thing , there is a role of inertia for sure, your explanation in my humble opinion is partially correct, the thing is that the boy's body is not a rigid body, so while in the first case there is a force of friction that tries to pull them forward the upper part of his body will try to stay as it is because of inertia, so in a way a part of the body that is legs are trying to go ahead and the upper part is trying to stay as it is, creating a serious imbalance and thus a fear of falling, this is where inertia is involved. In the second part of the problem , because of the wheels the lower part experiences little acceleration as you rightly said, so it is not disturbed much and the upper part's inertia is also almost untouched and thus more comfortable, your explanation is thus to my understanding partially correct!! More power to you sir!!
That is exactly what i was thinking
No sir... That teacher was not wrong he just didn't complete the explanation, that you completed it. Inertia is also playing a important role here, if there was no inertia then the wheel of the skates will not rotate, and the ball will shake same as without skate. That teacher is not wrong he is just explained incomplete, that you completed it. Thank you👍
Not 'ball' it will be 'boy'👆
Sir you are great teacher
I definitely recommend you for my younger brothers .

Yes he explained it very well. He was my teacher at IIT K
That is why I love you NMS sir 💖
Hello sir.. thank you for your nice explanation…need to tell something that in both situations the boy and the table are in same frame of reference. As friction force is an electromagnetic force, and oppose the motion of the body. The another force is reaction force that is acting in upward direction.
1. In first situation when we pulling the table, the resultant force of reaction and friction force is making an angle and acting in backward direction. The acceleration is not constant as we pulling the chair and stopping it. So the position of boy is dis balancing from its initial position.
2. Now the second situation is totally different as the boy can move with skates in the opposite direction. In this situation the acceleration of table and boy is totally different because we are pulling chair with same acceleration but the boy will move with more acceleration as rolling is there.
Now the table is experiencing more friction than boy. So the condition is more dis balancing.
Final observation:- This is not a perfect example of inertia and not an example of rolling motion. This is an example of non - inertial frames.
Thank you
Yaar ye baat itni logical or sach kyu lag rahi hai 🤔🤔🧐🧐

Great explanation Sir , Sir I am currently a 12th student and I am studying physics from Saleem Ahmed Sir and In 11th he teached us Rotation to a great level and Now I am able to understand all concepts I am writing this because I saw you somwhere with Saleem Sir.

Without wheels:- friction use to defeat inertia
With wheels:- friction force used in rotation
Moral of the story for other teachers or UA-camr: jb sabke father baithe ho to jada scientist nhi bante 😅😅😅😅😅
Aaj ache se friction ko ekword me samjh a gya k friction hamesha sath rakhne ka kaam karta hai ....yhanxs sir
Dear sir, can you explain the same by assuming a glass, steel and wooden ball having smooth surfaces instead of that lad. I m sure you will recall inertia.
Inertia to both case me tha.. first me static friction aur second me rolling friction.. ladka apne jagah pe inertia ke wajah se hi khada tha..( Agar inertia nhi hota to friction exist hi nhi krta )
Great Explaination Sir...
Scam of Experiments in Physics Busted.
1. Sir kah rahe hai ese bahot sare videos hai UA-cam per, but sir ne unhi teachers ke videos quote kiye jinke millions mein subscriber hai.
2. Sir itne bhole hai ki inhe lagta hai har student only IIT ya NEET hi karna chahta hai, sir board exam mein itne level ka question nahi pucha jata, cbse ke sample paper ke according chalna padta hai.
3. Dusro ko niche dikha kar aap upar nahi ja sakte, aap apne mehnat kariye wo apni kar rahe hai. Kam time mein success pane ka ye galat tarika hai.
Bhai pehli baat toh yeh hai ki anubhav sir n woh video 11th/12th k students k liye hi banaya hai and second thing galat concept sikhane toh acchi baat nhi ho skti hai ,chahe kisi b class ka student kyun na ho…tum ko sir ko thanks bolna chahiye ki at least sahi concept sikha rhe hain aur galat chizo ko correct kar rhe hain..varna zindagi bhar galat concept mind m betha rehta …
Dusri baat ,mujhe ek baat bata do UA-cam par videos views k alava kisi aur chiz k liye dalte hain kya ???
dono hi explaination shi h
because har ek phenomena ko 2 se jyada tareeko se smjhaya ja skta h
sir ne 2nd case ko standard condition maana aur aapne 1st ko standard maana that's why reasoning bhi alg alg nikli
physics ke koi bhi phenomena ek dusre se isolated nhi ho skte
umm tbh I couldn't understand it because I think I haven't studied some concepts used here, sir please tell at the starting of the video that these are the concepts that we are gonna use in this video so you must have some knowledge of these concepts, so that I can easily decide whether I should watch this video or not

Rolling 3:49 ka kya rol
Waah sir ji😂
Correct sir😂😂 doing experiment has become marketing strategy, and all coaching institute are in the same path😂😂
Measure of inertia is called mass.
In this case normal reaction is mg
This decides friction force so indirectly inertia has a role.
Of course the difference in two situations is attributed to sliding and rolling friction respectively.
Yeh inertia hee h at the end…. Takla zyada oversmart ban rha h lodu
*Dear, sir you are doing a commendable job. These day celebrity teachers are made God like figures. Many times they give wrong fundamentals in fun way and professional physicist from reputed institutes like iit and iisc do not object to them. These God like teachers think physics means class 11,12 concepts only. Now a days these mafia teachers are running a narrative that teachers from IITs have knowledge but do not know how to teach. It's a very dangerous thing because as common people won't understand its the adverse impact in the society.*
Equation + Emotion= Physics
Sir ne INERTIA observe karane ke liye wheels use kiya kyunki bina wheels ke friction bahot jada tha aur inertia observe karna mushkil tha jabki vo exist krta hai so jab friction ka direct impact body se hata diya gaya to INERTIA observe karna asaan ho gya
Aur apne ye explain kiya ki wheel ne friction ko exactly counter kaise kiya jo ki 100% sahi explain kiya hai
Par ye sochiye ap dono ne alag alag phenomena ka explaination diya hai
So ye kehna galat hai :- ki unka explaination galat tha apko ye kehna chahiye ki unka explaination adhura tha aur unhone jaan bujh ke nahi bataya
because unka motive ius time sirf nertia ke bare me batana tha us time friction wheel ke through kaise counter ho raha hai ye batana nahi
11 ke bachhe ko ek santh multi concept batayenge to vo bhag jaega isliye step wise time ke santh batate hai
Aur jinko lagta hai ki inertia kaam hi nahi kar raha explaination galat hai sirf wheel ka kamal hai
Vo oil ya greec table pe laga ke bhi try kar le same result hoga
✅️And imagine agar inertia kaam na karta body pe to body wheel pehnne ke baad bhi table ke santh chali jati kuki vo CHANGE IN STATE OF REST ko resist hi nahi karti to wheel ghumta hi nahi ek bahot minor sa friction force jo wheel pe lag raha hai vo bhi body ko khich leta table ke santh ✅️
Wheel ke jagah oil imagine kar ke dekho jada achhe se samajh ayega🙌
Simple bhasha me kahu to
1st case me friction dominant tha inertia se
2nd case me inertia dominent tha friction se kiunki wheel ne counter kar diya friction ka direct affect body pe padne se
So ap dono ka explaination 100% sahi hai bas apne wheel ka kamal bataya unhone inertia ka kuki unka topic inertia tha us time aisa nahi hai ki unko pata nahi wheel kaise kaam kar rahi hai friction ka impact body pe kam karne ke liye 🙏
I know apka kaam unko galat prove karna nahi tha us experiment ke baki ke concepts batana tha
Par log to galat hi samjh rahe hai 😂 apke title ko dekh ke ki apne galat prove kar diya sir ko
Teachers se sikho unko compare ya judge mat karo🙏
Very well said , its just a knowledge . There is nothing to prove someone wrong
🙏❤️

That's the difference between A Jee Teacher and a Foundation Teacher 😂
I also saw it and also was confused but its
Completely related concept
Thanks a lot
Thats crazy nms sir.❤ the moment you said friction i got the whole concept. You are legend man❤
Nms sir be like: jalwa hai hamara yahan
I think one action can be described by different laws of physics and don't u think saying inertia is a brider category and friction that u mentioned is part of it. And what if he says the inertia of the system
If it had happened due to inertia the students would not move back and forth
Although your explanation is correct, but to conclude that inertia has no role will not be appropriate. Through the experiment, the intention of the teacher might be to demonstrate newtons 1st law.
Since the rolling friction is very less the force exerted on the student is less, which is not sufficient to perturb the student.
To have better understanding, I will leave a question. What would be the behaviour of the system if the mass of student and mass of roller skate is very less (negligible)?
9th ke bacche sir ko comments me samjha rahe hai ki wo galat hai isse samjh ata hai ki inka selection kyu nahi hota ya hoga
Next level teacher... Jee advanced level ❤❤

Sir ji 80 kg mass kaise hoga wo toh weight hona chahiye?
Agar friction doo points ko sath mein rakhna chahta hai toh phir yaha friction lagna chahiye as due to rotational motion jo point contact mein tha abb upar jaa raha
You are great teacher sir
Wah sir Mai bhi Surprised hun ❤ मेरा भी भ्रम दूर हुआ
❤❤great explanation.
concept was great, might be a little error assuming the weight of child is 800kg, as you took his mass 80kg and W=mg (so his weight was considered 800kg!!!). 80kg would have resulted in 40N. but anyways it was a just a numerical mistake which has no effect on that crystal clear explanation.
good to see physics community growing :)
Tumlog experiment karo paise laga laga ke mai usko mind se hi galat karta hin 😂😂🤣 ❤❤
Literally in every this type off experiment they just say inertia and then move on this rolling amd friction thing also came in my mind when i saw this thanks sir for explaining thus
Very very good explanation ❤❤
Ghante wallah explain kar payega aise concept 😂
Thanks you sir , as a Physics lecturer i can say aap in aadhi knowledge walo ki jamkar dhulaai kr rhe , inke chakkar me humari class ke kuch students galat concept dekhkr, inke influence me aa jate h
Sir direction of acceleration due to rotation ( alpha r) opposite hoga n acceleration of(a) se
Sir NEET ki free classes youtube me upload kr dijiye ❤️
Sir but mass 80 kg k bjaye 8 kg nhi likha Jana chaiye? Kyuki 80 kg to normal reaction hoga weighing machine ka
Aap 10 example aise do jisme keval inertia responsible hai
Are you sure that limiting friction is there in case 1.
Why it could not be lesser than that as static friction can have any value from zero to μMg
Tab aap bolte ho ya to poora padhao ya mat padhao
Aur comment karne Wale kehte Hain ki bahut achchha concept clear ho gya
High quality teacher
Sir a1 aur alpha 1 ki direction to same hai only from contact point to com of wheel. At upper point it should be a1 minus alpha 1. Plz reply sir.
I am becoming addicted to your this type of tab. ❤
It is ok thak that friction is acting at that point, but saying that inertia doesn't exist at that point isn't ok.
Nice explanation but sir i have a doubt what if we move the table very slow then i think that the object on the table will also move with the table and the object is stable because we are fast and rapidly moving the table. So is there not any role of inertia.
Yeah khud ko newton samjhta hai isliye baaki teachers ko badnam karta hai taaki views aaye 😂😂😂
Sir ye series continue karo please
