1. Work is used to describe a change in energy. Without using technical terms, how could you explain this concept to someone who had not taken physics?
2. How are kinetic energy and work connected? What makes kinetic energy distinct from work?
3. A common misconception about the physical concept of potential energy is that you "store" energy at ground-level. Explain why this is not true.
4. How are kinetic energy, potential energy, and work all connected until conservation of energy? How do these ideas relate to mechanical energy? What advice would you offer others trying to understand these concepts?
