[@swegasaminathan9812]

You make me realise the happiness of learning Physics. This is indeed a great service to students. Thank you so much!

[@VG__]

I couldn't imagine understanding physics WITHOUT KHAN ACADEMY 🥺🥺🥺🙏🙏🙏🙏I am so eternally grateful to have Ram sir for my 10th class physics and Mahesh sir for 12th one. Brings me down to tears that I would have NEVER been able to understand physics had u people not been there🙏🙏🙏❤️❤️❤️❤️ love u both and thankyou eternity🙏 Thankyou Khan Academy, Thankyouuuuuuu so much. Thankyou lord almighty for this blessing!🙏❤️

Really mind blowing for a 10 grader...

[@danieldanieldadada]

I'm 30 and studied engineering and it's still mind blowing. I only had one semester of E&M, though.

[@thelastfight23]

You are the most excellent physics instructor I have ever encountered!

[@bluetopazy1249]

this makes 12th grade physics much easier tysm

[@beinghimself]

Amazing. You give the exact explanations i give to other people. It took me some time to understand these things and you’re explaining them in an amazing way to people who really need your help. Just continue what you are doing and get even more famous you will change a lot of things in people’s lives

1:40 potential energy converts to kinetic energy 2:40 3:20 potential energy from reference 4:15 example of number line 6:20 6:38 long story short 7:19 🌟 7:50 8:43 formula 9:30 woww, blown 😮🎉🤯

[@ashutosh-kumar]

Sir, Potential at point P is -300J/C, As you have mentioned at 9:52 that it would be 300J/C less than that of infinity. But when you said us to pause the video & think about it. I thaught Potential at point P is 300J/C more than that of Potential at infinity if I kept -1C charges at P. Is it correct or (negative😊)thinking?

[@KhanAcademyIndiaEnglish]

Yup that's true as well.

[@onkarprasad3294]

Sir, Your writing is very attractive...

[@yacobz]

literally came here to say that! Until he started writing in real time I just assumed it was made in some image editing software

[@UserK-3405X]

Its Very Helpful Thankyou

[@systummcrash004]

It would be better if you guys would provide notes for these too,as after I understood the concept to revise and review it again I would need those.

[@siddharthundefined]

Making your own notes with your understanding wouldn't hurt

[@phlegmsmoothie]

9:45 -ve potential explanation starting here.

[@vineet5701]

Love ur videos

[@grui-gv9ce]

Thank you ☺

[@patakotisrinivas1918]

Excellent sir

[@thefoodcouple95]

You are just fabulous!!! Mind blowing!!!! Thankyouuuuu

[@misschanandlerbong05]

Am I the only one who keeps seeing Dr Stranges's circle from the cursor?

[@crazyabc3915]

Second! Amazing!!!

[@hoffmanmustardoil6191]

So that means, everything in the universe tends to be at the lowest energy state (potential), that's why things tend to fall, rather than going up...

[@taehyun_kang]

Yes, because low energy means stability

[@suhaibhussain2222]

Awesome 😎😎

[@Jake-vb1xn]

This is so sick dude. Keep up the good work.

[@usaakshayadhana3149]

Sir please complete 12 cbse syllabus fastly

[@mukeshpatel3795]

Amazing explanation! !☺☺☺

[@shivanshjha938]

So can we say that the value of v at T is 8j/kg

[@catharperfect7036]

NIce. Now tell us how to hack into the NSA >>

[@DisiCoco-nm2gw]

Niceee

[@sakshishukla41]

so if a positive charge touches a negative charge then their potential energy will be -infinity? To me, this just sounds counter intutive because I thought potential energy in that case would be zero. Why can't we use the same analogy of positive potential that we use with like charges?

[@shauryaverma2705]

Lovely

[@phanishwarlal4838]

hey man, this guy explains things very well in both hindi and english but at many places, it's mentioned that voltage is electric potential *difference*, i am doomed, pls help

[@devanshrawat7179]

Bro, voltage is just the electric potential difference between two points in a circuit. It is just that the reference point changes from infinity to something like the earth (in the process of grounding). Everything else stays the same.

[@houriak848]

Sir I have a question when we have an electric field created by a charge q Aand there's a qB in point M we say that qB has a potential energy did this energy come from the external work we have to do to bring the charge from infinity to the point M or it's work done by qA on qB so qB gained a potential energy ?

[@komalvirk1439]

Sir , energy can never be created nor be destroyed ..but 3:25 here you said energy decreases to 3 joules..from 11 joules.

[@Jeremy73950]

It does not mean that the potential energy is destroyed, it only means that, it is the amount of energy that it exhibits in reference to that point. As sir explained in the previous video each object considering its given mass has its own potential energy but it will exhibit that in reference to some other point

[@komalvirk1439]

@@Jeremy73950 ok.. thanks. i understood that.

[@siddharthundefined]

Energy is not destroyed, It is just converted to another form of energy (KE).

[@alisaifzaidi6537]

please make videos in hindi

[@ahnafradi1942]

What will happen if I dont take a reference point?

[@zitscx886]

the actual value of potential energy is physically insignificant; it is only the potential energy difference that is significant.

[@qualquan]

unfortunately subject is being made unnecessarily confusing SIMPLY PUT: Electrical "Potential" is merely the "Ed" bit of QEd or Electrical Pot Energy where E = Electric field or acceleration and d = distance. Electric Potential is also called Voltage or EMF. Similarly gravitational "Potential" is merely the "Gh" bit of MGh or Gravitational PE where G = gravitational field or acceleration and h = height Work is mere TRANSFER of Energy from one body (donor) to another body (receiver). CONVERSION of energy from Pot Energy to Kinetic Energy in the same body is not work since there is no transfer of Energy from one body to another body You are welcome.
