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

Honestly, these videos make physics class so much more manageable. I appreciate the more recent uploads greatly. Please keep up the great work.
10:04 is the highlight of this video
Than i for u guys. Our modular teachers cant teach so we need to look for source to jderstand
You hit the hole! Thank youuuu pls make more videos and many lesson videos .thanks
Amazing !!💜💚💗
This channel should get 10 million 💝
I laughed when he started rotating the entire question.
I though angular velocity was radians divided by time. You multiplied (9:55)
The questions ought to mention the axis of rotation too, right?
Thank you so much
9:50 I found the final angular velocity to be 43.42 rad/s by using the v^2=v0^2+2ad
yea that's one way to do that
how can i get a 1.45?
What if revolutionsis missing. U need to findr evolution?
Wait....Sir there is a mistake in the last example
-[(40)^2]/[2 * 80pi]= -20/[pi]....
right?
No, if you use ∆Q=(W+W0/2) X t it gives t=6.28 and if you use α=∆W/∆t it gives the same answer
am i the only one think the last example calculated wrong?
does anyone know where he is? who is this David guy?
He actually explains really well.
Also, if you're looking for sal you'll find him on Khan Academy not Khan Academy Physics.
I can't learn now that Sal is gone
where the hell is SAL
