I'm about to take the AP Physics C: M test next week and your courses are way better than the Princeton Review books. I really appreciate your hard work and you definitely should know that these videos are saving many students! Next year when I take the E&M course, I'll be watching your videos again!
Your videos are very helpful and insightful! You have pretty much replaced my IB Physics HL teacher. We students really appreciate the time and effort you put in making these videos!
Thank You very much for these excellent physics videos! Very helpful! I have my AP Physics C Mechanics exam in two days and whatever grade I get will be because of your helpful videos. Thanks Again!
Hi! I wish I could tell you that, but it's one of the very non-intuitive concepts in physics. If the direction was in the direction of the velocity vector, it would be constantly changing, and we know that's not the case due to conservation of angular momentum. So, by convention, a right-hand-rule is used to determine the direction of the angular momentum vector (which also makes the math work out quite well with future calculations!)
excellent presentation. Can u tell me why the direction of angular momentum is not in the direction of velocity vector but at right angles to it and is determined by rt hand rule.What is the significance of this direction ? especially in case o fa rotating electron around a nucleus of atom
It's hard to do right hand rule in a video since everything you're doing in making the video is backward to the viewer. That's really a concept best taught in person... Love the idea, just haven't figured out a good way to do it.

오 한국인이다. 대학 잘 가셨나요?
I am truly honored to hear that you're finding these useful. I'll keep at 'em!

I'm taking AP physics C Mechanics online because of COVID-19 this year. These videos are helping so much! Thank you.
So glad you're finding these useful!

This by far is one of the hardest concepts for me
You're welcome!
Thanks! Good luck with your exam next week...
Best of luck to you!

Hey man this is great stuff keep up the good work 👍👍👍
+Kitkat123 Thanks, and will do!
so great!!! much better than our prof!!! thanks you!
Glad it helped you out!
Nice. Amazing stuff you have got here
Can you please do a video of just the right hand rule in different situations from mechanics and E&M?

Why would the angular momentum in the planet example go into the screen if the planet is traveling in a circle?
That is how angular momentum vectors are defined.
Great video, thank you!
Thank You Sir!
thx, dan!
thanks you're the bomb.com!
