  1. Thank you so much for these videos. The explanations are so clear and understandable. The use of graphics and illustrations helps clarify the concepts tremendously. As a fellow teacher I salute you for these outstanding lessons.

      1. Brian,
        I teach at a public high school in Michigan. Chemistry is my main focus and I’m teaching physics at the ninth grade level now. I have researched a lot of physics materials and have found your teaching videos to be exemplary. Thanks again for sharing such great work!


  2. i have some problems regarding work power energy. can i send you the questions and will you please solve? it will be very much helpful to me.


    1. The slope on the P vs T graph is the change in the Y value (position) divided by the change in the X value (time). It is also said a the final position – the initial position divided by the time. Pick two points on the line and determine how much the position changes between the points and divide that by the change in time! Does that help.
      Also try this website, it is very good,


  3. I attend a private college in Michigan and after beating my head on the wall for the last several weeks in physics, you have been able to make every point of confusion make sense. As I have said before, having a doctorate in a subject just means that one knows a lot about the material, not necessarily how to present it to others. Thank you for the videos.
    Any chance that you could do some on complex ions and k, ksp, and kf for chemistry>


  4. Thanks for the nice tutorials! But I am not able to find videos on oscillators like RC,LC colpitts oscillator,crystal oscillator,wein bridge.Can you upload its videos with its basic diagram and formulae. Thanks


  5. Hi, Mr. Swarthout! Your videos are very helpful, thank you!

    Could you do a video about electromotive force? They confuse me so… Especially in circuits with capacitors :’)


  6. Hi Brian, With Capacitors, Is there a different formula for calculating just 2 capacitors in a circuit than 2 or more? And also if there happens to be a mirofarad and a picofarad capacitor in the same circuit must you change one to the other before calculating ? Thanks again for the awesome videos.


  7. Thank you soo much. We didn’t have a teacher in Grade 9 so I started self-study in summer. I was able to cover most of the topics but thanks to your videos I successfully completed the Physics Syllabus. Thank you again and keep the amazing videos coming. 🙂


  8. hey can you please make videos on momentum and impulse. your videos have really helped me and it would mean alot if you do so keep up the great work


  9. Thank you very much sir for your videos on molar conversion which you have on youtube! They have cleared up my misunderstanding of how to convert between moles to grams and grams to moles, your students must be very lucky to have you as an educator. Thanks again and have a great day!


  10. Sir your video tutorials on youtube has been wonderful and great, I enjoyed watching and listening to you lecture.

    I want to compare an electric circuit to an economy and see how I can use kirchoff’s law to study how the inflow of capital or foreign direct investment is been affected by some opposition. Highlighting some factors like corruption, power shortage and foreign policy side by side with resistance, capacitance and inductance.
    Sir your views will be appreciated.


  11. hey sir !
    I’m just wondering when the x & y components equal zero when you solve force and motion problems?? .For example ; sometimes the y-component equal zero
    Fn=mg sin@ …..

    by the way I know one situation that y&x could be equal zero which is whenever a=0 !!


  12. Excellent presentation on parallel circuit calculations. It was extremely well thought out and presented in a manner that captures ones’ interest. I am currently studying DC theory, and want to know if you have any vignettes related to solving for complex combination (Series/ Parallel) circuits? Thank you.
