1. Do Now:
All objects have potential energy because all objects have the potential to move if an unbalanced force acts upon them.
Do you agree or disagree with this statement? Defend your answer with definitions and/or logic.

2. Another Do Now:
You apply a force of 12 N over a distance of .2 meters to a wagon. The wagon’s displacement is 8 meters. How much work did you do?

3. Dr. Feynman, I presume

4. After reading Dr. Feynman’s Block Lecture, Reflect on the following:
How comfortable are you with the idea that “something” can happen, but nothing happens to a physical, numerical quantity that is part of the “something”? Or, to quote Dr. Feynman, “It is just a strange fact that we can calculate some number and when we finish watching nature go through her tricks and calculate the number again, it is the same.”
Did you feel this way about the principle of Conservation of Energy before you read Dr. Feynman’s lecture?
Does the block analogy help you understand conservation of energy, even when you consider that there are no blocks, or do you now realize that this idea of energy conservation is much more complex and consternating than you originally thought? Elaborate.
Develop your own analogy for the conservation of energy.
