Conservation of Energy – John Jewett

Conservation of Energy – John Jewett wrote a series of five  papers in the journal of  Physics Teacher on how to teach conservation of energy. I have uploaded one of them. Read it and write at most a two-page report about the paper and try to address the following: the choice one has in choosing the system; the choice one has in choosing the time interval; the difference between the transformation of energy and transfer of energy; what do steady-state, isolated, and non-isolated mean; what are the types of energy transfers and the types of energy. Give an example of a scenario, e.g., you wake up in the morning, eat an energy
bar, climb a mountain, and write down the conservation of energy for that process. To illustrate the importance of time, you can compare it to another process: you wake up in the morning, eat an energy bar, climb a mountain, and walk back down the mountain, and explain how the addition of time (walking back down the mountain) changes the equation for conservation of energy.
