1. The diagram shows 2 identical charged particles. How does the potential energy and the force of repulsion change as the charges are brought closer together?
2. For the positions labeled on the image, list in order from highest to lowest the potential energy of the roller coaster. How is the kinetic energy of the roller coaster related to these values?
3. Consider the motion and size of the two vehicles headed for each other on the road. Compare the kinetic energy of the vehicles.
