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.

Test in 2 hours watched this at 3am and forgot everything
Well i like the underlining though. For me I feel very active when you underline things
This video is exactly what i needed, thank you so much, and also the underlining was really good in my opinion, thank you again
These videos are very helpful!

For the first question, if a 2M mass was used, the pendulum should be longer, and both of the periods should increase, right? I am so confused.
Why not post a PDF of the notes you are annotating?
great video, 1 question, can the speed of a wave (e.g. wave on a string) change by increasing the tension on the string?
yes it can. V = √f/√m/√L where f = tension
Transversr and logitudinal Waves , are in simple harmonic motion ?
thanks dude u saved me
THANK YOU OMG

I love you soo much
juju on that beat
Anyone having trouble with this class or am I just dumb stupid
you're not the only one
Great video. One thing though: STOP UNDERLINING THINGS!
