Returns the principal moments of inertia
(Ixx, Iyy, Izz) of the physics object, in the local frame, with respect to the center of mass.
1 Vector angularInertia
The moment of inertia in
kg * m^2
The unit conversion between meters and source units in this case is
1 meter ≈ 39.37 source units (100/2.54 exactly)
This value changes proportionally to the physics object's mass (e.g. making the object twice as heavy will result in it having twice the angular inertia)
