Conservation of Energy: Multiple Stages

Conservation of Energy: Multiple Stages

Conservation of Energy: Multiple Stages

You will use the law of Conservation of Energy to examples where there are multiple steps in the process.

An elastic band transfers $4000J$ of elastic potential energy to $2000J$ kinetic energy and $2000J$ heat energy. Does this example show the conservation of energy?

The image above shows the input and output energy of a hydro-power plant. Does this satisfy the conservation of energy principle? Answer Yes or No.

Which of the following does not demonstrate energy transfer over multiple stages?

Pick the correct statement.

What type of diagram might be used to describe the conservation of energy over multiple stages?

Have a guess as to how we might draw a Sankey diagram for an energy transfer in multiple stages.

Can you guess how many stages are involved in the energy transfer shown by this Sankey diagram?

Which of the following devices would have a Sankey diagram showing multiple energy transfers?

In a Sankey diagram, does the $\downarrow$ arrows represent the input energy at each stage of the transfer?

How does the Sankey diagram represent the conservation of energy principle?
