Dr. Radi Jishi’s AP Physics B course will help you do well in your AP course and prepare you to ace the exam. While this series is tailored to the AP test with plenty of free response type questions at the end of each lecture, college students studying physics will also benefit from the courses’ detailed explanations. Dr. Jishi also makes sure students fully understand the mathematics involved with a review of trigonometry and vectors. Topics include everything from Newton’s Laws and Conservation of Energy to Thermodynamics, Waves, and Optics. Dr. Jishi earned his Ph.D from the Massachusetts Institute of Technology, published over 60+ papers in peer-reviewed journals, and has been teaching for over 20 years.
