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!!
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.
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
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 )
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
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👍

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.
Sir wheel kyu rotate Kar Rahe Hai please explain, agar wheel me ko jam Kar de to inertia kaiser kaam karega. Bus me brake lage par passengers aage ho Jate Hai kya ye bhai inertia nahi Hai.
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. ❤
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)?
@@ISACSnf i understand what you're saying sir, but what I was talking about was a hypothetical - if the bearings were frictionless and the surfaces of the wheels and the table weren't, then what would happen? I feel like the kid on top of the table would remain stationary while the wheels rotate to accomodate the motion of the table
in bihar lauki is called kaddu and kaddu is called sitafal since my parents are from bihar and I am born and brought up in delhi it's alwaysvery confusing for me what is kaddu and what is sitafal especially during chatt on the day of nhai khai we locally call the day as kadddu bhaat and when I invited them to my house for the mahaparv they were completely confused why everyone is calling lauki as kaddu
Sir jab hm chote thab hame newtons 3rd law explain karne ke liye ya kahte ki. Jab ham ball ko wall pe marthe he aur wo bounce back hota he. Par wo galat uska koi aur reason tha momentum wala. Par school me tho kahte he kyunki hame concept ko catch karne ke kyunki ham use samajh nhi sakte complex. So don't blame that teachers your targeted audience is different and their targeted audience is difference. Unhe galat bolna galat hoga. Par concept clear karna uska example os good but don't blame them❤❤
my guess: moment of inertia of wheels is much less than inertia of boy, with wheels, only wheels move while boy remains more or less stationary. edit: sir mai thoda slow hu toh aapka explanation thoda sar ke upar se nikal gaya, for example wo 2f kyu hua. Sir agar aap ek trolley ka motion on a moving belt esa ek video banaye iss topic ke upar toh bohot maza aayega. vinati hai meri. Also sir another way to look at it is that when table underneath is at constant velocity, then pure rolling takes place without friction (static friction in horizontal pure rolling is zero) thus effect of adding wheels is equivalent to adding a lubricant which eliminates friction, thus due to inertia the boy stays at rest, so inertia is also the reason.
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
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
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
Sir lekin Anubhav sir ne weel use kiye taki wo friction (jo ki ek external force hai ) ko negligible bna skee aur Bina kisi external force ke koi bhi body apna state of motion change nhi krti ( jaisa ki video mai dikh rha hai ) yhi toh law of inertia hai 🙃🧐🤔🤔
sir ji mere pass ek doubt h ja sir ne table khinch tab wheel aage gaya jab sir ne opposite dakka diya tab bhi wheel thoda aage gaya aesa continuisly hua part 2 mein then tabhi to bachha aage gaya phir piche bhi aaya kya . isme to state of motion ka thoda inertia bhi use hua hai na aesa thodi n keh sakte h ki inertia ka use hua hi nhi . sir ye doubt mujhe confuse kar rahaa h please clarify it 🙏🙏
Sir aap assume kar rhe ho ki pehle case me bachhe ka total acceleration same hai, par aisa toh nhi hai, pehle case me bhi bacha still hi hai, uske par bas agey peeche ja rhe hain upper body nhi, par agey peeche ja rhe hain kyuki woh contanct me hain table ke sath, toh isme toh bacha inertia ki wajah se hi ruka hua hai, 2nd case me bhi bachha still hai, wheels rotate ho rhe hain, dono me inertia lag raha hai aur dono me hi baccha move nhi ho raha hai. Please tell me if i said this correctly.
Sir what if he says the inertia of the system.I think any action can be described by different laws of physics.And don't u think inertia is a brider category and friction that u used is part of it

Now the table is experiencing more friction than boy. So the condition is more dis balancing.

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
🙏❤️
Can Someone Help Me Which Teacher I Choose For Physics Saleem Sir And NMS Sir Who Is Best
Rolling 3:49 ka kya rol
Waah sir ji😂
Welcome dear professor 🎉🎉🎉🎉🎉❤ love you infinity ❤😊
Thank you! 😃
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.
Equation + Emotion= Physics
Sir wheel kyu rotate Kar Rahe Hai please explain, agar wheel me ko jam Kar de to inertia kaiser kaam karega.
Bus me brake lage par passengers aage ho Jate Hai kya ye bhai inertia nahi Hai.
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. ❤
Next level teacher... Jee advanced level ❤❤
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)?
Sir but mass 80 kg k bjaye 8 kg nhi likha Jana chaiye? Kyuki 80 kg to normal reaction hoga weighing machine ka
Agar roller skates kee bearings entirely frictionless hoti, toh forward acceleration nahi hoti na? Bas axial acceleration har wheel mein
It's not about bearing, friction is between surfaces
@@ISACSnf i understand what you're saying sir, but what I was talking about was a hypothetical - if the bearings were frictionless and the surfaces of the wheels and the table weren't, then what would happen?
I feel like the kid on top of the table would remain stationary while the wheels rotate to accomodate the motion of the table
Is that not what would happen?
Very very good explanation ❤❤
Very informative video sir ❤ and new approach towards content ❤
Sir wheel wale case mein friction ki direction kaise decide Hui...
Sir you take mass of boy = 80 kg
and gravity = 10 m/s²
So his weight should be 800 N which is not possible practically to see this guy
which class you are in?
Sir ji , aap to dusre sir ka hi class le rahe hai. Aab koi bhi sir experiment ke region batane se phle equation bnakar calculation jrur karege.
Sir calculation mai friction force divide hoga dono foot pr
Aapne umg 1 hi foot pr lga diya
in bihar lauki is called kaddu and kaddu is called sitafal since my parents are from bihar and I am born and brought up in delhi it's alwaysvery confusing for me what is kaddu and what is sitafal especially during chatt on the day of nhai khai we locally call the day as kadddu bhaat and when I invited them to my house for the mahaparv they were completely confused why everyone is calling lauki as kaddu
Acceleration ka volume kitna hota hain???
How can you say that in second case that experimenter is pushing and pulling easily
As mass is still same
Sir jab hm chote thab hame newtons 3rd law explain karne ke liye ya kahte ki. Jab ham ball ko wall pe marthe he aur wo bounce back hota he.
Par wo galat uska koi aur reason tha momentum wala.
Par school me tho kahte he kyunki hame concept ko catch karne ke kyunki ham use samajh nhi sakte complex.
So don't blame that teachers your targeted audience is different and their targeted audience is difference.
Unhe galat bolna galat hoga. Par concept clear karna uska example os good but don't blame them❤❤
you are revolutionary, keep it up sir
To kya sir agar next stage me table pr bhi wheels lga dete to A= a1+Rx1+Rx2? Note- Alpha ka sign nhi tha to x use kiya
Sir aap bihar me kaha se ho
my guess: moment of inertia of wheels is much less than inertia of boy, with wheels, only wheels move while boy remains more or less stationary. edit: sir mai thoda slow hu toh aapka explanation thoda sar ke upar se nikal gaya, for example wo 2f kyu hua. Sir agar aap ek trolley ka motion on a moving belt esa ek video banaye iss topic ke upar toh bohot maza aayega. vinati hai meri.
Also sir another way to look at it is that when table underneath is at constant velocity, then pure rolling takes place without friction (static friction in horizontal pure rolling is zero) thus effect of adding wheels is equivalent to adding a lubricant which eliminates friction, thus due to inertia the boy stays at rest, so inertia is also the reason.
Lauki bhujiya ek din sb ko achha lgega ❤tamacha h unlogo ko k liye jo sirf videos ko islyie bnate h taki youtuber bn jae na ki physics teacher.
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
You are the best teacher for physics
Great Explaination Sir...
Scam of Experiments in Physics Busted.
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
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
Wah sir.........mja aa gya❤❤
Sir ye series continue karo please
It is ok thak that friction is acting at that point, but saying that inertia doesn't exist at that point isn't ok.
Sir lekin Anubhav sir ne weel use kiye taki wo friction (jo ki ek external force hai ) ko negligible bna skee aur Bina kisi external force ke koi bhi body apna state of motion change nhi krti ( jaisa ki video mai dikh rha hai ) yhi toh law of inertia hai 🙃🧐🤔🤔
Tum sab 9th class ke baache ho kya 9th class ke hisaab se inertia hota hai wo ..abhi padhlo Aaage bahut kuch dekhna hai
@@esaff3761beta abhi tumsab baache ho lagta hai
O my gooood . I am so jealous of those who are taught by him
sir ji mere pass ek doubt h ja sir ne table khinch tab wheel aage gaya jab sir ne opposite dakka diya tab bhi wheel thoda aage gaya aesa continuisly hua part 2 mein then tabhi to bachha aage gaya phir piche bhi aaya kya . isme to state of motion ka thoda inertia bhi use hua hai na aesa thodi n keh sakte h ki inertia ka use hua hi nhi . sir ye doubt mujhe confuse kar rahaa h please clarify it 🙏🙏
Sir aap assume kar rhe ho ki pehle case me bachhe ka total acceleration same hai, par aisa toh nhi hai, pehle case me bhi bacha still hi hai, uske par bas agey peeche ja rhe hain upper body nhi, par agey peeche ja rhe hain kyuki woh contanct me hain table ke sath, toh isme toh bacha inertia ki wajah se hi ruka hua hai, 2nd case me bhi bachha still hai, wheels rotate ho rhe hain, dono me inertia lag raha hai aur dono me hi baccha move nhi ho raha hai. Please tell me if i said this correctly.
Beacuse off body was in rest only rotate was whell
Sor if he wanted to say the inertia of the system is he correct. And is it true that inertia is a brider term and friction is part of it
Aap 10 example aise do jisme keval inertia responsible hai
Sir what if he says the inertia of the system.I think any action can be described by different laws of physics.And don't u think inertia is a brider category and friction that u used is part of it
Sir please aap ek video inertia ke upar banaiye. Jisse ki inertia ki ek dum feel aa jaye
Sir u are such great physics teacher ❤❤ i love ur explanation ❤❤
Is it true for ground frame
Nms sir ko kota ki sbhi coaching ki ek ek class m bacho k sath bethya jaye , taki pta to chle vo bacho ko kya pdha rhe h , jb youtube pr ye haal h to 😂😂😅😅
Sir ap kya hi teacher ho amber batch me apka electrostatics 1 ka lecture dekha mene itne ache se charge ko samajaya apne 🙏🙇
Agar 11 th me hi ap muje mil gye hote to drop lene ki jarurat hi nahi hoti 🙇
First case me ladke ki body ka upper part applied force ke opposite kyu move kr rha hai??
You also giving half explanation
Sir aap kanpur me anish srivastava sir ke student hai na
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 ???
