ap physics 1 - unit 7 review: angular momentum
originally streamed in 2020 with Kelley CommefordTeachercurriculum note
This video refers to angular momentum as 'Unit 7' content from the older AP Physics 1 curriculum. In the current revised AP Physics 1 course, angular momentum and its conservation are covered in Unit 6 (Rotating Systems: Energy & Momentum), and rotational inertia is in Unit 5 (Torque and Rotational Dynamics).
