Inertia The energy contained in a moving or rotating body is not linear but quadratic to speed.
It takes 0.5 Joule to speed up that kilogram to 1 meter per second, it takes 2 Joule for 2 m/s, 4.5 for 3 m/s, etc.
Inertia if you mean the contained energy in your formula is not mass * radius but just mass * (radius ^ 2) / 2.
And remember, only the speed matters, not the direction; whether it is straight, turning slowly in a big circle or fast in a tiny circle is indifferent. Only its speed matters.
