Note that we need to define closed systems with respect to such nonconserved quantities as length, volume, rotational inertia, velocity of center of mass, force, potential energy, etc., as well as those with respect to One might respond that from Noether's theorem, we can infer alternative definitions of closed systems with respect to conserved quantities definition that a system is closed with respect to a physical quantity Q iff	./cache/work_pjahgqocmfh4tcslprmhd2ioye.pdf	./txt/work_pjahgqocmfh4tcslprmhd2ioye.txt
