5. a simple machine that consists of a rope that fits into a groove in a wheel
7. the energy associated with electric charges
8. energy dealing with temperature
12. the energy an object has due to its motion
15. the energy associated with the motion and position of everyday objects
16. the product of distance and the force in the direction an object moves
