This is a general question:
Does a higher coefficient for moment of inertia imply that it is harder for the object to rotate than for an object with a smaller coefficient?
We did this experiment in class where we rolled an empty can and then a can full of beans. The can of beans rolled faster than the empty can. We said that the can of beans was more massive, the mass was distributed closer to the axis, and I=1/2 mr^2 but ...meanwhile the empty can is less massive, the mass was distributed further from the axis and I=mr^2.
Does the coefficient have to do with it or is it just because of the mass distribution?
