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.

If you take the topic too deeper, both teachers explanations would be half correct.

[@positivevibes8771]

Exactly, NMS sir is somehow trying to put down every other physics teacher on KZbin, here in this example the role of inertia is of importance, the upper part of the body of the boy will try to maintain the inertia of rest and lower is being disturbed causing a twisting effect. And sir says inertia has no role here, boys body is not a rigid one . This is an example of BASE ISOLATION that is taught to structural engineers in the design of tall buildings to limit the twisting effect of earthquakes. He should try not to make it a mission to oppose every view held by other teachers

[@user-fd4qc6tz9e]

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.

[@apniphysics]

Very very good explanation ❤❤

[@PhysicsFables]

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

[@pritamyadav17]

Hello sir ,Veritasium ka "Falling Ladder ko bhi explane karo n

[@physicswithnavins5731]

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.

[@DanyalShabirr]

Yeh inertia hee h at the end…. Takla zyada oversmart ban rha h lodu

[@positivevibes8771]

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!!

[@nayanbaishya4077]

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)?

[@SandhyaKumari-bc3cd]

Sir wheel wale case mein friction ki direction kaise decide Hui...

[@4m0d]

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.
