Inertia affects only the resistance of a body to the change of state of rest to that of movement, even if density plays a role, it is not the only element that varies the inertia, the density makes it possible to fly by making itself lighter than the air (balloons) and for the change of the size it is by increasing the volume the power taking into account the mass and the volume
