This study guide covers the conservation of angular momentum, a crucial topic in AP Physics C: Mechanics. It explains the principle, calculations for point particles and extended objects, and key principles like the vector sum of angular momenta and conservation in isolated systems. It also explores common scenarios like colliding disks and the ballistic pendulum, combining concepts like rotational inertia, conservation of momentum, and conservation of energy. Finally, it provides practice questions and a final exam focus with high-priority topics, common question types, and last-minute tips.
