The missing word is "system."

In physics, a system (or physical system) is a group of related objects that interact with each other and form a complex whole. Examples: a gas in a container, the Earth–Moon system, an electrical circuit. Systems can be open, closed, or isolated depending on energy and matter exchange with their surroundings.
