Answer the following questions about potential and kinetic energy as Batman travels around Gotham City to fight crime. Be sure to explain your answer!

1. 
   Which has more potential energy: the Batmobile sitting on a flat surface in the Bat Cave, or the Batmobile stopped at a red light on top of a hill?
   
2. 
   Which has more kinetic energy: Batman standing in the Bat Cave talking on the Bat Phone, or Batman jumping from one building to another?
   
3.
