| Abstract: | A new theorem about the moment of inertia of rigid body is proposed and proved.This theorem states that the inertia of a homogeneous rigid body with a symmetry plane is not concerned in any direction of the axis that lie in that plane,when the axis that lie in a plane which be perpendicular to the symmetry plane meet certain conditions. |

| Keywords: | rigid body symmetric plane moment of inertia theorem axis |
