ap physics 1 - 2018 frq review: rotation, torque & waves
originally streamed in 2019 with Peter AppsTeachercurriculum note
This video references the temporary 2020 AP Physics 1 at-home exam format (open-book, only 2 questions, shortened 25- and 15-minute blocks), which no longer reflects the current exam structure. Check College Board's official resources for the current AP Physics 1 exam format.
