It this point this article quite clearly fails the good article criteria:
It should not be hard to fix these, but it could involve quite a bit of work. I'll leave this review open for week or so, to see if there is any progress. T R 17:08, 4 January 2013 (UTC)

Lead text should make clear that "moment of inertia" is a specific element from the inertial matrix.
In this article, that caveat comes too far down, in the "Overview" section in the well enough formulated sentence: "Moment of inertia around a fixed axis is a scalar, however the rotation of a body in space can occur around the three coordinate axes. In this case, the moments of inertia associated with the three coordinate axes define a matrix of scalars called the inertia matrix, also known as the inertia tensor."
At the very least, the first sentence should read: "In classical mechanics, moment of inertia, also called mass moment of inertia, rotational inertia, polar moment of inertia of mass, or the angular mass (SI units kg·m2, US units lbm ft2), is a property of a distribution of mass in space that measures its resistance to rotational acceleration about a fixed axis", rather than "..about an axis" Arildnordby ( talk) 00:00, 29 January 2013 (UTC)
2. Is not, perhaps, the inertia matrix important enough to warrant its own article, so that in your article on "moment of inertia", you may sharpen its focus by merely linking to "inertial matrix" article, retaining only MoI-relevant stuff, rather than using sections 6++ to develop concepts predominantly useful for analyzing/handling general rotation (like inertia ellipsoid, body-frame coordinates, and so on), concepts that are of little need (although, of course, trivially applicable there as well) in the single axis rotation case?

My apologies. Due to RL circumstances, I won't have time to continue this review. This is shame because there is lots of potential. Hopefully, Arildnordby can pick up my slack. T R 10:34, 29 January 2013 (UTC)
Placing this back in the review queue per above. Wizardman 17:51, 15 February 2013 (UTC)
