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.

[@arfdeep]

Wah sir.........mja aa gya❤❤

[@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)?

[@user-it7oz1we9v]

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

[@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!!

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.

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 :)
