Web3 jul. 2010 · Dear Deenar Apta, GD^2 is the ancient way to describe the moment of inertia in kgf.m^2. Nowadays, the moment of inertia is given as I = integral {distance^2 * d (mass)] in kg.m^2. It is the resistance against rotational changes, given by Torque = I * d (omega)/d (t) Linear equivalent is Force = mass * d (velocity)/d (t) This value plays a role ...
