if a fuel tank is launched empty and fuel is transfered to it later on it's rotational inertia stays as it was when it was empty

@DrexxVolv Newton's second law states that F=ma, in other words the force you need to accelerate a body is proportional to the body's mass. Similarly, the law of rotation (idk exactly what it's called) states that F=JB, where J is the rotational inertia of a body and B (it's usually beta but beta doesn't show up here) is the angular acceleration. J is always proportional to the mass of a body since a material point has a J=mR and a body can be approximated as a bunch of material points

@FlyingPotato_131 Except in zero gravity. Mass doesn’t change how hard it is to move/rotate if there is no gravity.

@DrexxVolv no. Both how hard it is to move and how hard it is to rotate an object depends on it's mass, whatever the gravity.
