  1. Hi Mr Fullerton. You are a huge celebrity in our classroom. I had a question. How does electricity in a circuit know how much voltage to drop across the first resistor if there are more circuit elements? How does it know that there are more resistors/capacitors to drop voltage for?

    1. Hi Chris — great question – really making me think! Instead of thinking about electricity as having to determine how much voltage to drop, try to visualize instead the current flow through a circuit as water traveling down a hill. Potential (voltage) would be analogous to height above sea level. If the first hill (resistor) has a 3-foot drop, that’s similar to potential dropping 3V as it travels across the resistor. This is why a higher voltage gives you more current (a greater altitude drop gives you faster water flow). So potential drop is kind of like the force that’s “pushing” electric current (and is why it is sometimes called electromotive force, or emf). Does that help it all? If you need more help, drop me a line on the APlusPhysics Community — I check that much more often and can also respond with equations, pictures, etc. there. Thanks!

  2. Hi Mr. Fullerton, I’m having a great amount of difficulty in AP Physics 1. I’ve been watching your videos, reading your book, and I’m still not getting it. Any advice? My brain just isn’t hardwired for physics no matter how much I try to understand…

    1. It’s a tough class and takes a while to really get it. I would note that the books and videos are meant to compliment a formal physics class, not substitute for it, but really it’s about perseverance and those hands-on activities that help you make meaning of the concepts. Good luck!

  3. Hello Mr. Fullerton!
    It is my school’s first time offering ap physics 1. My classmates and I are very grateful for you book, videos, and website. A lot of us are confused in class and we always refer to your videos in class when we don’t understand something and then we all get whats happening in class. So I’d like to say thank you very much on behalf of me and my class for all of your help and resources.
    We consider you an imperative part of our physics family!

    1. Hi Sarah,
      Thank you so much for the kind words and the great support — I love hearing from students who take the initiative to find resources to help themselves when they don’t understand something — it bodes well for a very promising future! You are very welcome, and I’m absolutely honored to be part of your physics family. Make it a great day!

  4. Hello Mr. Fullerton. My 9th grade daughter is struggling mightily with physics. She needs a hands-on, kind and creative approach. Are there any Boston-based or internet-based tutors you can recommend? Thanks so much!

    1. I don’t know of any experts in Boston, but I might look into Educator.com. I think highly of their online instructional quality and I’m one of the physics instructors available in their catalog. Another place you might try for a tutor is Wyzant.com.

      1. Thanks so much for your speedy reply and for your suggestions. It’s hard to know which online sites are reputable so your recommendations are helpful.

  5. Hello Mr.Fullerton!!!
    I am currently a senior in a high school and I received some devastating news 2 weeks ago… I couldn’t take Physics C because the class was full 🙁 But, I am passionate about physics, and I am determined to take the AP test. I was wondering if I would be prepared to pass the exams by watching your videos (and take notes on them, using physics classrooms for labs, doing the class homework, and taking practice tests.
    Thank you!!!

    1. Hi Ted,
      I’m always a fan of group work and deeper discussions, but I don’t see any reason you couldn’t be successful working independently through a textbook, videos, labs, etc. Sounds like a fantastic challenge, and I love to see passionate young men and women finding a way to be successful!

  6. Any advice on AP physics 1, we have kids who understand concepts well but still not doing well on the sample college board AP physics 1 questions. Any input on resources for practice questions would be much appreciated.

    1. Practice questions: APlusPhysics.com –> Courses –> AP Physics 1

      It’s a very tough test, one that I think is a bit too challenging compared to the what I believe the aims of the course should be.
