From a little bit of thinking, this is what I concluded:(adsbygoogle = window.adsbygoogle || []).push({});

A system initially at rest can change its angular position without any outside torques (the final state will also be at rest).

A system initially at rest cannot change its displacement without an outside force.

In other words, cons. of linear momentum also implies that a system cannot move its CM without outside forces, however, cons. of angular momentum does not prohibit a body from changing its angular orientation without outside torques, due to the fact that rotational inertia can be changed internally.

Is this correct, or can anyone offer counterexamples?
