Rotational Inertia

This study guide covers rotational inertia, also known as the moment of inertia. It explains the concept, the formula ($I = mr^2$), and how mass distribution affects it. The guide also covers calculating rotational inertia for rigid systems and off-center rotations using the parallel axis theorem ($I' = I_{cm} + Md^2$). Finally, it provides practice questions and exam tips.
