That means less energy in the key and wippen (we = didn't change their inertias). So if we have the same total energy, = less in the key and wippen, then MORE must have gone into the key, not = the same amount. =20 Yes, you're right. I totally misread what you had written. I agree. A = distillation of this concept is that the energy distribution between = components is proportional to their inertial contribution.
