AP Physics 1 and AP Physics C: Mech (Part 13: Mixed Force Problems) | Office Hours with Al

In this stream, we briefly touched on the topic of equilibrium, then started looking at some more complicated problems, as well as problems were simple, but still significant for their ability to illustrate concepts. There was also some emphasis on developing the habit of asking follow-up questions to gain more out of one's physics study time.

Sorry about the footage being a bit blurry for this one. I made an adjustment to the camera focus and it looked better in the preview window, but I guess I should've tried a test recording before going with the new settings. We should be going back to normal quality next time.
