Line 1: ~~The~~In [[physics]], the '''parallel axes rule''' can be used to determine the [[moment of inertia]] of a [[rigid object]] about any axis, given the moment of inertia of the object about the parallel axis through the object's [[center of mass]] and the perpendicular distance between the axes. Let ''I''<sub>''G''</sub> denote the moment of inertia of the object about the center of mass, <var>M</var> the object's mass and <var>a</var> the perpendicular distance between the two axes. Then the moment of inertia about the new axis is given by:
