    I finally made an index of all my videos on youtube.  You need flounder no longer.  Try http://docphysicsindex.com, where I've sorted the videos by chapter and put them into a reasonable structural order.

    Hi, Are there any videos for ch 22? I couldn't find a playlist. Thanks!
    Doc Schuster
    Greetings, my northern friend!  You've put a smile on my face.  Keep warm this winter and get ready to rock university!

    does the centripetal force change if the center of rotation is already rotating around another center ? Example: (if sun gravity affecting earth is 9.8m/s^2 are we going to be weightless at night and ejected to the sun during the day? )
    Doc Schuster
    Yeah, it would add up as vectors like that! Complicated!
    crowxe
    the example came out wrong, it was supposed to presume that the centripetal force of the earth rotating around the sun is 9.8

    God bless your funny soul, Sir!

    And you, too!  Thanks!

    You really know how to get things nice and simple! Keep up the good work! Greetings from Italy
    Doc Schuster
    Thank you!  I love Italy, too!

    Hello!! Could you please please quickly (before May 1, and at the very max before May 18, I have an extremely important entrance exam on May 22 and this topic, while I sort of get it, I don't really really get it.) do some videos on variable mass systems and rocket propulsion, preferably with a few problems? Thank you so much for your videos. They've helped me a lot over the past two years of school.
    Doc Schuster
    +STSfoxface L That's a negative. This is a busy time for me, too! Thanks for watching, though. Sorry. Advice: keep working problems and then try to teach it to someone else.

    Fantastic videos. Circuits finally made sense to me.

    Your Calculus videos are amazing. Thank you!

    +Noahnrg22 thank YOU!

    Do you think that uploading on : ...( surface tension / angle of contact for fluids on a surface/ excess pressure inside soap bubble due to surf. tension )...would be good idea for you ??
    Doc Schuster
    I'd have to do some research, but it would be fun to investigate.  I'm sure you'll be better off finding it elsewhere if you want to learn about it before 2016, though...

    Hi, I was wondering if you could show us how to make our own inductors for diy electronics.
    Doc Schuster
    +Randy Travis I'll defer to others for that.  I love DIY electronics, but I am a learner in that field, not an expert.  Let me know what you find, though.  I'm beefing up my electronics labs this year.

    He is on his first semester of Aircraft Mechanics at Centennial College and he was pretty much lost on this.

    As of 13/05/2014 (dd/mm/yyyy) you have uploaded 100pi videos :)
    Doc Schuster
    WOOT.  And then I go and bust it for some stupid worked example!

    I'm a second year science teacher, and your videos are so invaluable for my physics class! I teach all three core sciences (bio/chem/physics) so having a resource like this has been a god send! Thank you!! :)
    Doc Schuster
    +Marian Iskandar Yay! I remember how hard it was in those earlier years. Stay strong!

    It would be great if you post a lecture explaining more about Moseley's experiment and X-ray :P thank you very much 
    Doc Schuster
    Sounds great!
    keith brooks
    hey doc thanks for the videos they are very helpful could you explain in your way the difference between impulse and impact. thanks
    Doc Schuster
    Impact is not well defined.  Sounds like a force to me, though.  Impulse is force integrated over time (or force times time if they're still hiding calculus from you).

    pls add vdos of logic gates and number systems....

    I love how enthusiastic you are in all you videos. It makes me feel more excited to study.
    Doc Schuster
    I'm glad you're beginning to share my excitement for physics!  It's so great!
