Assess students' ability to apply conservation of mechanical energy and rotational dynamics to analyze a rigid object rolling without slipping down an inclined plane. Tasks should require equating loss of gravitational potential energy to translational and rotational kinetic energy, using the object's moment of inertia to compute angular speed and linear acceleration, deriving final speed and acceleration in terms of angle, radius, and mass distribution, and explaining the role and direction of static friction and why no work is done by it. Include both quantitative problems (e.g., solid sphere, solid cylinder, hoop) and conceptual questions comparing outcomes for different moments of inertia.
