best teacher of physics on youtube

[@Bugra0528]

there are many great teachers out there just like him...they are just very difficult to find...it takes time...but yes I agree with you...he is an example of a perfect teacher!

Woah now it seems like physics is on finger tips( though i know this happiness will not last for so long)

Sir u can make anyone understand in a simple manner thanks a lot sir ...👏👏👏👏

[@sahaj2121]

thankyou so much sir

[@brahmendrachirumamilla6851]

Sir, in the starting you told about the direction of the earth. My question is why earth rotation is different to clock rotation?

[@rabindrasingh4377]

Bhai sahab inertial frame aur non inertial frame k baare m padha hoga na....

[@sudeepkumarmahana6883]

Sir, Why centrifugal force may have two components that you have made ?

[@vaibhavtripathi691]

Represent direction of CF in vector form

[@adarshkumaryadav2403]

Vector pada h aapne

[@nomorephysicsfear7295]

We always resolve the vectors into two components ( horizontal & vertical) here we resolve into 2 components one is along the line joining of centre of the earth (horizontal) and another is perpendicular (vertical) to it.

[@bigyanadh4952]

Clean and crystal clear sir

[@rocksdown1807]

So much nicely explained thank you very much sir from Bangladesh

[@Avenger_s]

What a wonderful explanation sir 😊😊😊

[@learnwithfun1973]

It makes our concept clear...thank u so much sir

[@MATHSNISHANTVERMA]

sir , experience really matters u explained it very well

[@ajaahhw6503]

Sir no centrifugal force work on a moving object. Centrifugal force is a reaction force of centripetal force. Centrifugal force work on the object which is in center of the circular path.So centrifugal force works on earth(center), not on the object which is above the surface.

[@jubairtayib8312]

bro u are absolutely right .......i have watched a lot of videos ...all of them are speaking about centrifugal force.....no one is describing this in terms of centripetal force

[@chinusaxena963]

No centrifugal force acts opposite to centripetal force away from the centre, so what he is saying is right

[@academyoframeshwarsaransh2514]

Star ho kya

[@vamsikrishnab1848]

Centrifugal force is a pseudo force in non-inertial frame. It is equal in magnitude to the centripetal force but not at all a reactive force.

[@sanuraj5998]

Vamsikrishna is right. Centrifugal force is not a real force. It is a fictitious force and it acts only when the body is analyzed with respect to an accelerating frame of reference (in this case, a rotating frame)

[@sawaidan9880]

Wow brilliantly explains

[@fatima0642]

Love you sir ❤

[@griffin4078]

Very nicely explained...

Thanq sir this video was really very helpful for me

[@pratitimaharana7604]

Tq sir for your effort. Great respect to you🙏🙏🙏

[@sri1882]

Does speed of rotation changes with change in latitude number?

[@vaibhavtripathi691]

I think.. theta represents (lattitude no. Or lattitude angle) i.e Theda depend upon lattitude no.... So we can say that... Speed of rotation change.....

[@varunkumar-ee7jq]

No speed doesn't as far as ik because v=rw as per rotation and hence it is independent of theta but force and gravitation changes

[@Dobetterlivebetter]

it was a great explanation sir

[@ramu12r]

U are in class 11

[@rhymeahmed5361]

Thank you very much sir.. Its help me so much.. ❤

[@apucitepucu]

Sir is it like since g' is minimum at equator, so most of the rocket launching centres are located near the equator So that less gravitational force gets exerted by earth ?

[@sumitkumarpushpam8007]

Ayush Rohila may be....!

[@dipeshrawat2587]

The g at the Equator and that at the Poles have comparable values , not very large difference at all, about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the Poles. So I think they can send rockets from Poles too

[@abhinavjain5230]

@@dipeshrawat2587 It matters a lot when you are sending something to the space.

Thank u sir .

[@arpityadav6298]

THANK YOU SO MUCH SIR

[@btsstarz]

Thank you sir 🙂

[@sanmeshsanjayshintre9060]

At 12:54 , I thik g should be written as g= GM/R^2

[@mathuraanganmathu2489]

U r correct i also have seen that

[@trs101]

I cant understand why F'=mrw^2 cos(lembda)

[@varunkumar-ee7jq]

F=mv2/r for centripetal force,centrifugal force is dimensionally same therefore substitute v=rw which is the logic behind rotation

[@Usuraj_5300]

Thank you sir for nice explation

[@rajameyyappan2868]

But why do we take gravity = 9.8 m/s² for all altitude, latitude?

[@satyamtripathi7736]

To solve numericals easily 😂

nice one tq

[@AkshayKumar-nn3xv]

Sir g increase as we go deep in the earth till 2800km and the value there is 10.8m/s2 and then decrease throw some light here sir

[@sri1882]

But what may be the reason for decrease in g value due to rotation of earth? Why rotation of earth affects the g value ?

[@robertloderer6143]

Because centrifugal force is oposing gravity

[@freneticjoker657]

W sir 👍

[@deepanshusuman9921]

4:27 sir how did you got that the force mg is greater than mgw square cos theta

[@deepanshusuman9921]

Ans : because if not then the object will not on the surface of the earth it will something not on the earth

[@rabindrasingh4377]

Bhai sahab circular motion padha hai na....

[@Mjamsher]

Sir due to rotation g will increase or decrease?

[@vamsikrishnab1848]

decreases but at the poles remain unchanged

[@vishalmishra8988]

Decrease but at poles will remain constant

[@prernapal2680]

Nice

[@sreelakshmykalathur212]

superb SIR

[@abhinav2702]

Thanku sir...

[@allnews7841]

what is the gravity if rotation of earth stop??
