Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
For free. For everyone. Forever. #YouCanLearnAnything

I shed a tear, its so beautiful
i feel ya bro
@@dioptre thanks sis
@@sollinw not sis, but ok
@@dioptre I know, I just did what u did.
@@sollinw oh my god, im sorry lol
AMAZING! My professor just threw out the words "Boltzmann's constant," gave us the value, and that's it. I had no idea what it was for or how it came to be until now!
Knowing the how and why is so darn important, so thank you for giving me that.
I have to say I can't appreciate you enough for making a video explaining this, I'm just you're average Joe I didn't even graduate highschool to be honest it's really a blessingto be able to have this knowledge at my fingertips. I've just been interested in physics lately specifically astrophysics and it brought me here, I've been struggling with this but you explained it perfectly 👌 thank you so much!!
@Philip Randall I see a lot of such comments nowadays. This is scam everyone knows. ruclips.net/video/EnSACqWo3vI/видео.html
@Bryant Maverick this is your another account.
What do you think people will believe you
Bruh
wrrr
your*
@@aarushisingh7983 ??🤭😂what
Tq Khan Bro, Ur videos r really helpin me
Sir you are awesomeeeeee!!!!!
Gracias capo, muy clara la explicación!
Excellent explanation as always. Thank you very much.
Oh my God, mind blowing explanation
Guys every time if you find something useful please make sure to like the video
Now it's crystal clear , ThanQ Sir 🍻
Thank you Sir. It was a great help😊
Great explanation - I agree with all the folks who commented before ! I am in my late 40s. Electrical & electronics engineer. I used to hate equations, although I am always curious & like to understand them. Perhaps & probably, never had many teachers who has explained equations or derivations very well during my studies. Also I always skipped derivations & equations. This explanation is marvelous. Physics/Science is useless unless it can be explained in a simply way like this.
Khan Academy has made RUclips more interesting for students ❤
please explain the virial theorem. hanks
When calculating the boltzmann's constant, Na is (molecules/mole). I know the moles cancel out from the R constant but what happens to the molecules? Shouldn't the final units be Joules/Kelvin * molecule?
its the number of molecules
it has no units
just a number.
The final unit is joule per Kelvin
It was very beautiful explanation thanks very much I was studying for medical entrance NEET 😍😘
I love this thing
Thank you so much
Okay so how do explain radiation of heat by Sun? In this kind of transfer of heat there is no molecule striking and photon is massless. Also how you will explain heat transfer in a conductor? When you touch a hot iron rod you feel hot but the particles of iron shouldn't be moving in way by which it can strike your part of the hand yiu feel hot.
Plz sir I will be grateful if uou explain me this
Praise be to the person who made Khan academy
8.31 and 1.38, just the reverse, cool.
What is the ESSENCE of boltzman constant?!!
It is the R in the ideal gas law, except defined at the level of the individual molecule, instead of the "Chemist's dozen" that we call the mole.
The units are cubic-meter-Pascals/Kelvin. "Cubic-meter-Pascals" eventually translates to Joules, the energy units.
@@carultch 💯 thanks
Thanks sir...
What is formula to derived Boltzman Constant
1,3806488*10^-23 J/K
wrg
waaaaaaaaaaaaaaaaay better than uworld explanation. Thank you so much for this succinct video explanation. You're a boss!
ya lost me when math came into it
You take a definition and make a new definition. So what? I hoped you would tell us whether Boltzmann's constant is a fundamental property of nature, like Planck's constant or the speed of light. Indeed, the essence of the second law is that entropy is nondecreasing. The constant of proportionality is inconsequential.
S = k log W was never discovered by Boltzmann although it is often mistakenly attributed to him.
It was the great Max Plank who coined the equation and evaluated the value of Boltzmann’s constant. Boltzmann had no clue neither about the constant not the equation on his tomb.
You can look this up.
The fact that he commit suicide breaks my heart
Especially tragic since some unknown guy, "A. Einstein", published a paper in 1905 on Brownian Motion demonstrating the existence of atoms.
The audio is atrocious! The equalization is so bad that it physically causes me pain :(
