Sir my kind request please upload concept bending of cyclist in curves on physics book scert tamil nadu text book page no 232 it is very difficult for me to understand that concept please put video on it sir your the best physics teacher I have seen in my life I saw all your videos on RUclips you put motivational videos also so I like it please make video of bending of cyclist in curves my kind request sir
Hello, your statement at 6:53 relation of moment of inertia with distance from reference axis is not correct. Please do correct it before it reaches many students as it could result in wrong understanding of concepts for students. Please don't get offended, just take it as a positive criticism. Regards, Vinoth Kumar Endurance Engineering Academy
You are really great sir my physics mam taught me this concept in a very tricky way thanks soo much sir please upload all concept videos of 11th std physics scert syllabus then all concepts would be clear for us and wishing you advanced happy diwali
No sir your wrong with concept because MOI increases with distance increases from center axis.because higher distance seeks higher torque to rotate the object ie high inertia occurs to rotate it
Sir you explained whats moment of inertia as moment means motion and inertia means rest so instead of naming moment of inertia they can name it as motion of rest no sir ??
Hello bro! Nice video, but you explained the concept(Example) wrongly. Roughly in the 6-7 min part of the video. when the distance(r) is more the moment of inertia is 'high' and vice versa (i.e) directly proportional. Plz, listen to it once! Thx.
Sir I have an doubt ,in the second example first case you told that moment of inertia is high,if it is high then the speed of rotation will be decrease then how in first case the object rotate fast.pls clear me
You are doing a great job at helping others students out by sharing your knowledge at the youtube platform. I truly appreciate that. But the thing is I believe you can do more in taking lessons to deeper level. I feel like you're not stepping out of the book level. We know moment of inertia is MR2... but why has to be the case? Yes with daily life experience I know, when I rotate a mass that is at low radius, i feel like i rotate it with ease and at mass with higher radius,its otherwise and my intuition agrees with that,but i feel your job as a teacher should be to explain why we feel easier in one case and not in other.Not just to end with the reason saying' This is because moment of inertia'.This may make students convinced momentarily,but also prone to raise doubts further. And first of, moment is not motion and inertia doesn't mean rest. Moment means 'rotation aspect' and inertia means 'inability to resist motion'. That being said, when two bodies rotate at say 10cm radius and 30cm respectively, we know that one rotating at 10cm radius and other at 30 cm radius have same angular velocity but DIFFERENT LINEAR VELOCITY. I stress on this point so much, because due to this different linear velocity at different radii, we had the need to bring a new term 'Moment of inertia'. Because just this 'inertia' term didn't serve justice in explaining the diff MI we experience at diff radius because Mass is same at all radii, and inertia only deals with mass in translatory motion. But moment of inertia deals with both mass and radius. Now lets take two masses say 5kg and 2kg and we have to accelerate both by 1m/s2 . Now the force needed for 5kg body is 5N and 2kg body is 2N, the thing is in changing its position from rest to motion by increasing its velocity to 1m/s in 1 sec, both body need different forces!!Do you acknowledge something here!! To change its motion by same amount, two bodies need different forces, thus this 'mass term' can defined as force needed for a body to accelerate it by 1m/s2, which turns out to be 5kg in this case , so mass is not just amount of matter contained in it, we have to perceive it in diff angle here, it is the amount of force required to accelerate this body by 1m/s2 and also this amount is called as inertial mass. Now had it been the same mass both of 5 kg instead of 5kg and 2kg, the force would've been the same, thus meaning that it has the same 'inertial mass/inertia' to change its position from rest to motion by accelerating with 1m/s2. 2kg mass has less inertia, meaning it needs less force for it to accelerate by the same value 1m/s2.This is the way to understand inertia. Now what's so special about 'Moment of inertia or Rotational inertia (i would like to call it rotational inertia because that's makes intuitive sense) from mere INERTIA?See,I believe you know that at diff radii, a particle of same mass has diff velocity but same angular velocity, so when rotating these two bodies of mass M at diff radii about an axis, with same angular velocity, the one at higher radius need to travel large arc/distance in the same time as the one at smaller radius which only have to travel smaller arc at the same time for the same angular velocity, having diff MI for same mass at diff radii.Just explore why and how of every phenomenon of physics until you get the satisfaction from the right source. I know this is a long answer, but I always felt like venting this out because i feel like you have potential to go higher than this , also very less are the people who teach in Tamil here ,making you a constant source of help for many tamilians here.I hope you consider my concern:)
Sir u told distance clase to centre of mass has high inertia. But sir according to equation inertia is directly proportional to distance that s radius so if did disance increases inertia also increases. Am i correct sir
sir i think i spotted an error from 6:50. You told when the masses are present far from the centre then the moment of inertia is less but the moment of inertia should increase during stick experiment... Kindly check my query, i have also typed the explanation.. Explanation: The moment of inertia depends on the mass distribution relative to the axis of rotation. Marble at the Center: When the marble is close to the center, the distance from the axis of rotation is smaller, leading to a lower moment of inertia. Marble at the Corners: When the marble is at the corners, it is farther from the axis of rotation, resulting in a higher moment of inertia. Therefore, the stick with the marble at the corners has a greater moment of inertia compared to the stick with the marble close to the center. Kindly check and tell sir!
where are you still now sir ? when i was totaly sad about my physics marks you came inside my life and you changed my life by your physics video i am crying now sir because i am setting simply sir and thinking i will fail in my 11th but you came inside in my life like an hero i love you sooo much sir god bless you sir always you will never fall down i like you so much . if i go to tution they are asking 12000 for each subject we dont have that much money to pay sir i dont know what to do sir that you entered in my life sir thank you sir if you want any help ask me sir i will definitly do sir i am there for you sir thank you.
SIR I KNOW YOUR A TEACHER IN MR NAGAR CBC SCHOOL IS A CORRECT TA SIR MY SIR IS BEST FRD FOR YOU MY SCHOOL WAS ST.JOSPHE HR SEC SCHOOL IN BHARADHI NAGAR...😅
Sir I think u explained wrongly in 6:54 ...moment of inertia means the rotating object needs to be in rest position ...moment of inertia is higher rotating capability is less since "I" is proportional to mass and radii.
Ji... Neenga sona concept lam correct... But at the 7.25 point la, distance (r) kammiya irundha M.I adhigam nu mention panirukinga... Actually adhu wrong.. r adhigamaa irundha M.I adhigam aagum... And vice versa, r kammiya irundha MI yum kammiyaagum that's y it rotates earlier and faster
Super vdeo sir. Guys take a plate and a top(pambarom), spin them at the same time , see what hapens ........... Difference in their movement......... Moment of inertia-The BOSS........Haha hope it helps...
Moment of inertia. I=mr^2 That mean if r increase, then I increase. It mean whenever a moment of inertia increased in object their rotation get slow comparing to the object which get low moment of inertia.
Sir long ah irukum pothu moment of inertia adigam sir so velocity decreases athanala than slow aguthu neenga moment of inertia adigam nu soldringa confusion ah iruku sir

Yes sir, I got the pt. For a longer distance moment of inertia is high.
Please verify the concept. Ur teaching is good in many concept.
Thank youuu sooo muchh sir i understood clearly 😩💗

You are really great sir my physics mam taught me this concept in a very tricky way thanks soo much sir please upload all concept videos of 11th std physics scert syllabus then all concepts would be clear for us and wishing you advanced happy diwali
Same to u ma🙏
Same here
Sir, mass centre point la irunthu thalli irunth r value increase aagum so moment of inertia vum increase thana aagum sir.
Yeah!
That's torque
This is moment of inertia
Yes, moment of interia increase aachu na speed of rotation decrease aagum.

No sir your wrong with concept because MOI increases with distance increases from center axis.because higher distance seeks higher torque to rotate the object ie high inertia occurs to rotate it
Thank you for teaching 🙏

Moment of inertia. I=mr^2
That mean if r increase, then I increase. It mean whenever a moment of inertia increased in object their rotation get slow comparing to the object which get low moment of inertia.
Try to understand this by their formula. It can help you to understand much better
