Vocabulary  System: A set of interacting things (systems)  Interaction: An exchange of organization among systems  Energy: Motion within a system, or transferred into or out of a system. A measure of actual or potential interaction.  Organization: An arrangement of systems in a system such that certain interactions are much more likely than others.  Work: The capture of energy into the organization of a system.  Dissipation: The release of energy from an organized system.  Efficiency: The ratio of work to total energy flow.
