Objects of equal mass and radius but different shape or solid/hollow will roll down the incline at different rates.Solid cylinders of different mass and radius roll down the incline at the same rate & reach the bottom at the same time.

Interpret results in terms of moments of inertia.

Roll different objects down the incline in race fashion, starting them with the meter stick. To show objects that have different moments of inertia accelerate at different rates when rolling down an inclined plane.
