I'm going to take AP Physics C: Mechanics in my next year of high school, so having this lesson here at Khan Academy would be super helpful. On top of that, I've noticed that there have also been multiple people requesting that AP Physics be added to Khan Academy. In fact, one of the Ambassadors of Khan Academy responded to the request that AP Physics has added to the 'Wish-List,' however that comment and reply were made 7 years ago. So I'm hoping that Khan Academy will very soon add AP Physics C courses, as it would benefit many students.
