Thank you very much. I have watched a lot of videos trying to explain Einstein's equation but you are the first one to make me understand why the speed of light is part of the equation.
I want to learn from best and finest teacher like you ☺️....i am addicted to your way of teaching.
Soo .. some Videos needed
1. De broglie's hypothesis(mordern physics)
2. Dimagnetic and paramagnetic material (chemistry)
And it seem the channel is a bit underrated...but dont loose hope sir ...you are providing knowledge you are doing your part you need not worry about anything..lots of love from Nepal 🇳🇵❣️🍂
I will try my best to cover these...
👍👍👍
how old r u
18 plus
You master the art of making the most complex topics, the easiest
Amazing! I understood it all..Thank u so much ❤️❤️
I m late Sir to find you but I got you Sir... I m learning a lot easily by watching your videos Sir... Please don't stop uploading more videos Sir...U r a real teacher 👩🏫..Please make more videos of 11th, 12th and Graduation standard Sir...
Very well explained. It's not just for students but for all age groups. Thanks so much
Ur way of explanation..is simply 👌👌👌.I became a fan of ur lecture sir 👏👏👏👏
You're The Best Najam Academy
Sir you are teaching very clearly and nice explanation 🙂🙏🏻🙏🏻
THNX
Welcome 👍 💗
First full video watched viewer ❤️
Thank you so much 💓 💗 💛
Than you sir for your understanding
It's very helpful thankyou sir😊😊🙏
I am watching your videos when i was in 11th just because yiur explaination is best❤️❤️
Thank you so much 💓 💗 💛
Your way of explain the lecture are very amazing. You are very talented I appreciate your affot your drawing amazing. I have no words. May Allah success you in every field of life and you can enjoy good health with wealth ☺️☺️
Thank you so much 💓 💗 💛
Thank you sir🤩
Thanks ❤
Love you sir 💕
Thank you so much 💓 💗 💛
Nice
Thank you so much 💓 💗 💛
3:21 our body dont build muscle by energy , energy is used for its working and it builts by increasing the rate of protein deposition while minimizing the rate of protein breakdown
Sirr! well explianed🎉
Such an amazing video
Sir, put video about Young's modulus
Osm work
Very simplefied
Sir! Plz explain difference between General theory of relativity and Mass energy equivalence?
I share , like this vedio and suscriber of your channel
Excellent video! Especially liked the explanation for a kid.
Why does the speed of light have to be squared?
Sir, I know the c^2 comes from the algebraic derivation...But why it is squared..it can be c, c3,c4,c5...so on...you get the point...Apart from the Energy Unit Analogy, is there any other universal significance of c getting squared?
I also want to know this.
Actually we know that SI unit of energy is joule or kgm^2s^-2 So the equation should have c^2 to make the unit same .if we take only c then the unit fro eqn E=mc will be kg m/s which is not correct .Therefore for the correctness of this equation the dimensions or units on both sides should be same
@@rajveertoor1643 Thank you so much for your kind information.
@@rajveertoor1643 but I have already stated about the Energy Unit Analogy above...I need more profound answer than that🙏
Wait for the legendary explanation.
😊😊😊
Sir❤❤❤
Nice, do you have a video on Kinetic energy?
10:06 Mass is increased or volume?!?? 🧐🤔
How can you say that if the matter is completely converted into energy it will travel in the speed of light??
And why c2is written???
Speed of light
Sir How you are doing editing like this??
Sir penetration par video bnaye
Sir P-T diagram please.thank you🙏😍
sir from which app you edit the vedio
Key of this equation
Sir, ice is melting. Don't you think it also has some kind of energy. Please sir reply me back
🕉️🟰MC²
According to sanatam dharma 😇
Sir how to solve physics numericals please sir
When the Indian accent comes, I could rest assured that it's easy to understand. Well we could convert apples into energy by eating them. Now let's get serious, find a way to convert inner energy into a small flame so I don't need a lighter anymore. Yeah, convert mana into fire magic xDD
Explain why c is squared
Newtonian derivation of E = mc²
In Newton’s law: Force = mass x acceleration
(Areal velocity = constant is included in Newton’s law)
Newton’s gravity law F = - (G m M /r2) r1
Acceleration in mathematical form is:
(rʹʹ - r θʹ2) r1 + (2 rʹ θʹ + r θʹʹ) θ1
Force = mass x acceleration = m x [(rʹʹ - r θʹ2) r1 + (2 rʹ θʹ + r θʹʹ) θ1];
Force = F = mass x acceleration = - (G m M /r2) r1
And m (rʹʹ - r θʹ2) = -G m M /r2 ---Newton’s gravitational force law.
And (2 rʹ θʹ + r θʹʹ) = 0 -------------- Kepler’s constant areal velocity law.
Divide Kepler’s law by r θʹ
Visual distance: r = (distance) r₀ x e± i ω t
Visual angular speed θʹ = (angular speed) θʹ ₀ x e± 2 i ω t
= r₀ e± i ω t
And θʹ = θʹ₀ e± 2 i ω t
And (2 rʹ / r + θʹʹ/θʹ) = 0; rearrange: (2 rʹ/r) = - (θʹʹ/θʹ) = ± 2 i ω
In Kepler law: Areal velocity = (r2θʹ) = constant
Or (r2θʹ) = k; r = distance; θʹ = angular speed
Take the derivative: d (r2θʹ)/ d t = 0
And (2 r rʹ θʹ + r2θʹʹ) = 0; divide by r2θʹ
And (2 rʹ / r + θʹʹ/θʹ) = 0; rearrange
(2 rʹ/r) = - (θʹʹ/θʹ) = ± 2 i ω
And (rʹ/r) = ± i ω
And d r/r = ± i ω d t
And ∫ d r/r = ∫± i ω d t
L n (r/r₀) = ± i ω t L n e = L n e± i ω t
And r = r₀ e± i ω t
And - (θʹʹ/θʹ) = ± 2 i ω
And θʹʹ/θʹ = ± 2 i ω
The solution is: θʹ = θʹ ₀ e± 2 i ω t
If r₀ e i ω t; θʹ = θʹ₀ e- 2 i ω t
If r₀ e - i ω t; θʹ = θʹ₀ e 2 i ω t
E = mc²
S = r ℮ ỉ ω t
P = [v + ỉ ω r] ℮ ỉ ω t
(P. P) = [v² - ω² r² + 2 ỉ ω r v] ℮ 2 ỉ ω t
E = m (P. P)/2
= (m/2) [v² - ω² r² + 2 ỉ ω r v] ℮ 2 ỉ ω t
E = (m/2) [c² - c² + 2 ỉ c²] ℮ 2 ỉ ω t
With ω r = v = c
E = (m/2) [2 ỉ c² ℮ 2 ỉ ω t]
E = (m/2) │2 ỉ c² ││℮ 2 ỉ ω t│
E = (m/2) (2 c²)
E = mc²
If you have 1Kg of water it would have more molecules than 1Kg of ice and would have the same mass. Now if you melt 1 Kg of ice it would have more mass after melting since the amount of molecules remains the same.
E=mc²/c... incidentally, there is no speed of light (photons) it's an illusion -its a reaction time you're measuring :-y
11:50 but ice have more potential energy
No we are relating K.E with mass not P.E
i'm just a little boy who is in grade 3 i'm already learning physics
Ya got a small error that may confuse some you combined two hydrogen and two oxygen but are missing the second oxygen from your equation
💗💗💗🌹🌹🌹
So lovely explanation ❣️☺️
heat is not mass, all reactions follow conservation of mass ,unless it is nuclear.
Prove it
If we eat an apple . It is converted into energy and our body uses this energy to build our muscles.
Where Is speed of light role in it?
If you turn it all into energy and never defecate or use any other form of extraction then sure. But that's not the same
I think you are completely wrong about the increase of mass with the increase of the energy because E=MC2
Is just a special case and the car with more motion has no more massive than a rested car
🧐👉H2 + O > H2O
Sir aap ki electron microscope ki video nai aai but meri mdcat ki date aagai😣😣😣😭😭😭
Anyone in 2024
Saying this energy is converted to mass is completely wrong
Nice
Thank you so much 💓 💗 💛
