Perhaps you should try some spelling variations:
rotational inertia » rotational energy, rotational kinematics, rotational invariant
rotatory inertia » rotary inertia
motion inertia » motion intention
rotor inertia » rotary inertia, monitor inertia, robots inertia

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rotor inertia) OR (motion inertia))) OR (((rotatory inertia) OR (rotational inertia)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rotor inertia) or (motion inertia))) or (((rotatory inertia) OR (rotational inertia))))".
• Adding a wildcard symbol may retrieve word variants: ((((rotor inertia) or (motion inertia))) or (((rotatory inertia) OR (rotational inertia))))*.
