Students taking AP Physics Classes might want to watch YouTube video lectures posted by the College Board. Generally, the first week of videos are for topics taken OFF the upcoming 2020 tests. Later videos will be review for topics ON the test. However, AP Physics 1 started with rotational kinematics which is ON the test.

If you have questions about the test or physics let me know. I might know the answer, or I can try to find out.

The general link for science videos is:

Rotational Kinematics (On test)
Torque and equilibrium. (On test.)

AP 2:
6.1 The Wave Nature of Light, 6.2 Electromagnetic Waves (Not on test.)
6.4: Refraction. (Both scheduled.) (Not on test.)

AP C ME:
