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 am wondering if you could possibly explain Rankine and Engine cycles (Otto, gas and diesel). Also, for a Mechanics of Materials class: Mohr's Circle. Thanks for all that you do...you're the best. I owe my Linear Algebra grade to you. Kind Regards, Mechanical Engineering Student

Thank's to your videos, I have managed to get my bachelor of physics! Thank you!

[@twilightawakening]

This is amazing. Thanks so much! Very greatful!!!

[@hamisiwenge1369]

very helpful thanks a lot

[@hrn8935]

Did anyone else find this proof oddly satifying

[@Soban144]

Thanks

8:24 Didn't understand.HELP!!

[@shayanmoosavi9139]

It's an elementary integral. The integral of 1/x dx is ln(x) and since it's a definite Integral (it has upper bound and lower bound) it's evaluated at those points. If you still don't know what I'm talking about you should look up definite Integrals.

None of my teachers taught us Carnot Cycle better than this ....always something was left and Carnot Cycle has always been a source of Headache to me ........i wish had a teacher like u in my college/university........Thanks Sir

[@jacobvandijk6525]

Your first teacher laid the foundation and Sal just build on that. Sal had an advantage, because you already met the concepts. So calm down, please!

8:15 starting velocity?? I think he means volume

[@vaidik177]

Human error

[@ateb4076]

Wow thank you I really needed that part relating tempreture and volume in adiabatic process. Thanks for perfect way of explaining.

[@mikerockwell1975]

George Takei, is that you??

[@shimblypibbins]

Wow

[@HotPepperLala]

awesome
