ap physics 1 - rotational kinematics & torque
originally streamed in 2020 with Kelley CommefordTeachercurriculum note
This video refers to rotational kinematics and torque as 'Unit 7,' which reflects the old AP Physics 1 curriculum numbering. In the current AP Physics 1 course, this content is covered in Unit 5 ā Torque and Rotational Dynamics. The video also references an outdated exam format (MCQ removed, only two FRQs) that no longer applies.
