Don't see view just see the quality of teaching and education!

➡️➡️But guys in the last moment of this video, 2 solid sphare which reduii is different how its reach together at the bottom Please friends and sir explain me

[@dumbi09]

This helped me better grasp the concept of rotational momentum. Thank you!

[@IB_and_A_Level_Physics]

You explained this very well. A big thank you from China!

[@Arsemaesubalew]

Best lesson ever! As clear as a glass, thanks!

[@tsegakagnew6442]

Thank you 😊 such a nice way of teaching and I hope too see more

[@michaelspurlock3096]

Could you please show the equation whereby mass and radius cancel out?

[@vikashkumar9585]

Such a shame that this video has so low views.

[@NoName-ot8kl]

He is a nice teacher.

[@swarnashissarkar4767]

Excellent Appreciated and very well explained Sir..

[@TrangNguyen-ql8ox]

Great demonstration! Thank you!

[@masoudsakha]

Perfect explanation

Thank you so much sid .you explained it very well.

Hello I was wondering if you could help me with a unique flywheel calculation please? If I had a way of magnetically supporting a huge flywheel like the one illustrated in your video. Lets say 50 meters in diameter. Is it possible to spin that flywheel with an outside rim speed of 1600 km per hour?

[@TexusNoe365247]

Would this concept also extend to flywheels? For example, a solid flywheel vs a semi-hollow flywheel? Which flywheel would store the most energy?

[@sanjeen2503]

Yes, the concept is applicable to flywheels. But be careful! While designing or procuring a flywheel, you would have your own constraints which will be very different from this physics demo. For example, if you want a cheap steel flywheel that can store the maximum energy for a given thickness and radius, the ideal design is to use a solid steel disk of the same thickness and radius.

Great explanation sir

But the smaller sphere has a lower moment of inertia and did reach the bottom first.

[@rabiasultan8853]

well then shouldn't moment of inertia be inversely related to rotational k.e?

[@siddharajpatil6200]

thank you sir for explaining this concept

[@oluwagbemigaotunaiya8566]

I understand better now thanks alot

[@alexis9158]

wow really clear! love it

[@yok0012000]

where can one get these sets of discs/hoops/sphere of identical mass?

[@naight173]

As far as I understood, you don't need identical mass, because it cancels out
