Rotational Inertia Set • ME-9774

With this set, students will learn that the speed of an object rolling down a ramp is determined by the shape or distribution of mass of an object

How It Works

Compare rotational inertias of objects with different shapes and sizes. Students learn that the speed of an object rolling down the ramp is not affected by its mass or radius. The shape or distribution of the mass determines the outcome. The sphere will reach the bottom first, followed by the disk. The ring will be last.
