I was taught there was two types of inertia. The translational inertia and the rotational inertia. If in the Earth for example, that has a translational motion around the Sun, and a rotational motion around itself, all forces disappeared, it would follow an uniform rectilinear motion tangent to its previous translational motion around the Sun, and would continue in uniform circular motion around itself.
But would would happen if in the ball, that was initially moving around the red axis below, suddenly disappeared all the external forces? Consider the distance of the axis to the center of the ball is R/2 for example.
