 ==== Wrap Up Questions ====
   - Qualitatively, how does the energy change in this system? What types of energy do you have? Are they increasing or decreasing? Is energy conserved? (It may be helpful to draw energy bar charts here.)
-  - What is the sign of electric potential energy in this case? What does it mean for electric potential energy to be positive or negative?
   - When the spring is fully compressed, what is the electric force on the positive charge? What is the spring force on the positive charge? What is the net force on the positive charge?
   - What is the general approach to solving a physics problem using energy? (What steps did you follow in this problem?)
