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.

This is a bit fast. It is hard for the weak or struggling students to get you. If you could make it a bit slower then that would be great help for everyone.
Thank you so much Mr Khan. Your videos helped me understand doppler effect better than my text books.

brilliant
Temperature period and tension are all represented by T
that blue smiley face is as creepy as a neutrino o_o
I don't think so. No.
did he mix up the last two formulas
this is amazing! god bless you cuz you just saved my life an the test I have tomorrow will be easier! Thanks!
I've been confused about the sign in this formula for a while now, but this video explained it in a very simple matter, thanks a lot! Really appreciate this channel
So you change the sign in the formula depending on if it's moving away from or towards you?
where are all these videos? they aren't on the khanacademy website
It might be nice to make a video about the "doppler illusion" i.e. the additional perceptual distortion that happens because very few people know about it.
Emm, what?
