Energy Flow when doing Work
System A Does Work on System B
When a SYSTEM does WORK it loses energy: DESYS < 0
When WORK is done ON a SYSTEM it gains energy: DESYS > 0
- Whenever work is done, energy flows from one system to another. What one system loses the other system gains - the conservation of energy.
- Work is a transfer of energy when one system exerts a force on another system. It is not a property of a system like a system's mass, volume, or temperature.
