The 16 pages that link to System boundary, each with the reason it gives.

• Life-cycle assessmentRelated: Boundary choices decide which life-cycle processes contribute to the result.

• Conservation of energyRelated: Whether energy is conserved depends on what the chosen system includes.

• Conservation of momentumRelated: Whether a force is internal or external depends on where this boundary is drawn.

• Mass balanceRelated: Choosing the boundary determines which transfers count as inputs and outputs.

• Free-body diagramRelated: The boundary decides which interactions count as external forces on the isolated object.

• Scientific modelRelated: Choosing what lies inside the boundary determines what the model must represent.

• Systems theoryRelated: Choosing a boundary determines which components and interactions count as part of the system.

• Systems thinkingRelated: Boundary choices determine which causes and consequences an analysis includes.

• Material balanceRelated: The boundary fixes which material transfers count as inputs or outputs.

• Energy consumptionRelated: Changing the boundary can change which uses count toward a reported total.

• Energy return on investmentRelated: Including or excluding extraction, refining, transport, or infrastructure changes the ratio.

• Isolated systemRelated: The boundary is where prohibited matter and energy transfers would occur.

• Systems analysisRelated: Choosing what lies inside the boundary determines which interactions the analysis must account for.

• Reynolds transport theoremRelated: Boundary motion and transport across it determine the theorem’s flux contribution.

• Software architectureRelated: Boundary decisions determine which responsibilities belong inside the architecture.

• Intensive and extensive propertiesRelated: Changing the boundary can change the system size and its extensive properties.
