The size, weight, and mass distribution of a cylinder influences its moment of inertia and determines the speed at which it will roll down a ramp.

Place the two contestants at the top of the track behind the stopper. Lift the stopper to start the race.

Possible match-ups are

1) cylinders have the same mass but in solid and one is hollow.

2) cylinders have the same shape but different masses.

3) cylinders have the diameter but one of is solid and the other is hollow.

4) cylinders have the same diameter and mass but their mass distribution is different (one centred and one around the edge).
