In Classical Mechanics
In nonrelativistic classical mechanics, a closed system is a physical system which doesn't exchange any matter with its surroundings, and isn't subject to any force whose source is external to the system. A closed system in the classical mechanics sense would be considered an isolated system in thermodynamics.
