11:23 "Making the staircase even smaller" is a nice approach to giving an intuitive understanding of integration while calculating work done. Well done!

[@ishajogmarge6663]

we need to appreciate his work..indeed all his video has nice explanation i think his work is underrated

[@Sonikoranga_yoga]

Omg... this feels like something i already know..... this vedio deserves more views!!! even the method of namo sir(god of visualising physics) didn't get into my head and this is something amazing thanks a lot!

[@manans4251]

pehle video ki spelling dhang se likh le

[@PrittamSarkar]

Thank you sir my whole year was wasted thinking about this

[@sequalsr2550]

Excellent video it cleared all my concepts.

[@mahnoormukhtiar9072]

you deserve millions of likes. who agree ?

We realise in higher education in a more precise way "Work done is path independent in a conservative vector filed ( Divergence is 0 , ex : Gravitational force field). " But sir made it super easy for school students. ❤

[@AnujKumar-so2hd]

Thank you sir ❤️❤️❤️

[@Oshin-md8qn]

Thank you so much sir after a stressful day at school your videos give me hope 😅

[@AbdullahButt-in8ev]

Brilliant explanation

[@introvideo5064]

The best teacher I never had!!!!!!

[@electricity2703]

Just brilliant 🎉

[@AsfandYousafzai-s8h]

I can't find enough words to appreciate you teacher

[@alemuemiru2654]

Wow amazing 🤩🤩 Good job 👍👍

[@KanootJan-lo5mq]

Wowwwww❤

[@gutzimmumdo4910]

12:37 i dont think that curve is the same as the previous curve, there is a point in the curve where the height will increase and the distance is not going to be equal to the straight line. btw i love your videos and the way u teach, very clear and intuitive, far better than other khan academy lists.

[@introvideo5064]

Excellent work!!!!!!!!!

[@4gomegalife764]

👍👍👍awesome

[@mihikaroy7161]

Wowwww........🖤🖤🖤🖤❤️❤️❤️❤️

[@shouryavardhandatta2170]

That is why we should take the displacement in consideration not the direction.

[@dinklekriplani]

Yar rally bro very very nice explanation this could really help us all a lot really you did it in very easiest way really this helped us a lot....❤️❤️

[@AdeenaFatima-jr3ce]

Thankuuuuuuuuu❤

[@fatimalearns9618]

Thankyou so much for this video! Indeed a very beneficial video it is! :)

[@srustigchinni2999]

Loved it !!! Amazing

[@LafangayParindey]

8:52 What will be the displacement if the body is moving upwards

[@RasibRao-g6r]

Amazing animation

[@leylakhan5414]

Totally amazing lectures

[@sabarishks6089]

Thank you so much sir.

[@aena_]

Perfect explanation

[@aena_]

Things started making sense...ohhhh

[@soumadip5319]

superb

[@atpTUBE]

WOW that understanding was greaatt! I didnt even think about it :)

[@danielmok5458]

You explained it much better than my physics teacher Jason Chan

[@subhankarmondal3024]

You understand it better from here because you learned that before from anywhere else If you watch this video at very first and then join your physics teacher's class Jason chan then you definitely found that your teacher's explanation is better than this. When we learn a topic 1st time and then 2nd time from other sources then we feel 2nd explanation is better than previous one. It's natural with respect to our brain.

[@Ali-tf5oe]

Oh mannnnn I love thissss

Very useful

[@aena_]

Thank you

[@ApkaAhmedYousaf]

Ah ...now i can breathe freely😅...your explanation made me happy

[@sukriti900]

No doubt sir 😃 that this is the best explanation video of this topic on yt 🌟✨ Amazing....!!! Just speechless explanation 👀👏

[@mdrezoanul5065]

thanks

[@aena_]

Best video

[@ArunKumar-wv1uc]

thanks a lot Dil se, majo

[@AsfandYousafzai-s8h]

If the ball (second) move in vertical and as well in horizontal axis the force of gravity apply force only in vertical direction then due to which force it move in horizontal axis too

[@skb730]

Can't we simply use w= fscostheta for the slope??

[@aena_]

Good

[@neiljohnrobin7088]

How about when it goes up?

[@HamnaUmar-b6n]

Sir why the motion of ball in free fall is faster than the inclined plane motion?

[@deadshotgaming9662]

Because as you make it fall down w/o an incline gravity accelerates it faster but if you put an incline it accelerates less. Make it make sense w a formulae. As,W= f.dcos∅ if u put theta 0⁰ it has a value 1 and if u increasetye angle it lessens ie,0.866 at 30⁰ etc

[@ashutoshsadana1312]

Nicee

[@arkytectarchi11]

Wonderful explanation tx a lot

[@Queen-jz4fl]

I DIDN'T UNDERSTAND BRAVOOOOOOOOOO!🙂

[@AsfandYousafzai-s8h]

Please get my question and answer me

[@9kArdos3]

On your last craziest staircase, there is a birth of a new, larger height, compared to the original one. Work done only by gravity is never ever relevant, gravity is an effect of the nature of reality, without reality there is no gravity, it does not exist outside of it, so don't imagine that it does without emphasis on this being relevant only for understanding or simplifying calculations, or maybe for the education system to torment students with nonsense. Don't get me wrong, you seem lovely, this thought should help anyone who really understands it.
