Energy Transformations. Energy Transformation. Energy being converted from one type to another in an isolated system. Electrical Energy Mechanical Energy. But what is an Isolated system?. Looking only at what is right in front of you and not thinking back to where it all came from

Energy Transformation • Energy being converted from one type to another in an isolated system Electrical Energy Mechanical Energy
But what is an Isolated system? • Looking only at what is right in front of you and not thinking back to where it all came from • Reason we use isolated systems: all energy eventually can be traced to the sun but mapping it back to that point would take FOREVER and be pointless to answer our questions
Energy Transformation Diagrams • Pictures labeled with energy inputs and outputs including “wasted energy” (Inputs) (Outputs) Electrical Electromagnetic *Note how long the arrows are! Thermal (“Wasted” Energy)
Draw the energy Transformation Diagram for a microwave including inputs, outputs and “wasted” energy (Inputs) (Outputs) Electrical Thermal Mechanical Electromagnetic (“Wasted” Energy)
Describe the energy transfer through the isolated system. But there is more than one transformation happening here… What do we do?! Electromagnetic Electrical Mechanical
Diagram the energy transformation through the isolated system using an energy transfer diagram But again, there is more than one transformation happening here… What do we do?! (Inputs) (Outputs) Electromagnetic Mechanical Thermal (“Wasted” Energy)
