This study guide covers the conservation of angular momentum, including what it is, how to calculate the sum of angular momenta, and how external torques cause changes. It also explains angular impulse and its relationship to changes in angular momentum. The guide explores how angular speed changes in non-rigid systems when the mass distribution changes and provides practice questions involving collisions and changing moments of inertia. Finally, it highlights important exam tips and common mistakes.
