Education
Race a block, a hoop, a solid disc, and both kinds of sphere down the same incline and watch moment of inertia decide the finish order every time. A live "why" panel shows each object's shape factor and resulting acceleration as the race runs, tying the outcome directly back to the underlying formula. Friction only affects the sliding block — rolling objects don't lose energy to kinetic friction, and the race makes that distinction obvious rather than abstract.
