Various hoops, cylinders, and spheres, some with the same outer radius are set rolling together to see which will reach the bottom of an inclined plane first. In a Solid Disk vs. a Hollow Hoop, same mass and same radius, the solid one will move ahead demonstrating its lower moment of inertia. Also,Mathematics can show the mass cancels with conservation of energy. What happens with rolling spheres of different radius? | |||

Various hoops, cylinders, and spheres, some with the same outer radius are set rolling together to see which will reach the bottom of an inclined plane first. In a Solid Disk vs. a Hollow Hoop, same mass and same radius, the solid one will move ahead demonstrating its lower moment of inertia. Also,Mathematics can show the mass cancels with conservation of energy. What happens with rolling spheres of different radius?
