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 love how he hopes we find it "reasonably interesting," lol. not "incredibly" interesting or even "very" interesting. just "reasonably" interesting. :D
I am still watching this in 2022 and this video is 11 yo 😶🤯
Where have you been all my life
I once asked my science teacher WHY snell's law faces a singularity at i = c and total internal refraction occurs and he was stumped!
once again, I don't know what would I do without your videos. so much love to you Mr. khan
My teacher has been explaining it for the past hour and I had no clue what she was saying. I understood right away after watching this video!
thank you so much ! I litteraly study in french and english is not my first language and i’ve learned more from this video than from class😭😭
This really helped a lot, I'm 14, i need to learn this in foreign German though :c this is going to be so hard xD
Thanks for this video, helped explained this better rather in class. Fully understood the concept behind critical and total internal reflection. - grade 10 student
Once you had explained total Internal reflection, I whipped out my scale and even tried it in practical....and it worked....Thanks for explaining in ruch simple words and making it understandable
Man, why cant i have teachers like this? Mine just sits there and talks like i can imagine what the .....*.... he is talking about. Thanks.

Thank you, Mr. Khan! You are the one who helps me to escape from my boring physics lesson!
I swear no one teaches like Khan Academy!

This wil help me so much for my physics test tomorrow!
Sal, you are a lifesaver! Summer classes have us learning this whole playlist in 3 days and it's going to make up around 25% of the final. I was so stressed but 3 hours of sitting down and watching this playlist actually makes it manageable. Thank you, thank you, thank you!!!
Thxs a million!! Khan Academy videos have been helping me for 2years now! Sal's the best at making complex things simple!!
I need my teacher teach like you,interesting and easy-understanding
Thank you SO much! This has been immensely useful and makes far more sense than it did before I watched the video! Many thanks
