physics and chemistry is actually pretty fun cuz i'm a geek

3. 20 meters east from her original spot
6. potential energy is energy that is stored and ready to do work. kinetic energy is energy that is in motion.
7. joules
8. potential energy is converted to kinetic
9. change in velocity divided by the change in time

i wonder if any of those are right
