Ring and Disk Apparatus Conceptual Physics Snell’s Law and more withDemonstrate rotational inertia with a surprising race down a ramp The Ring and Disk apparatus delivers a classic, thought provoking demonstration of rotational motion and inertia. Two objects of nearly equal mass and radiusone a solid disk and the other a ringare released on an incline. Which reaches the bottom first? By requiring students to reason through rotational inertia rather than just mass or size, the Ring and Disk provides a clear, engaging
