16. The energy an object has due to motion.
19. Potential energy that depends upon the object’s position above the earth or height.
20. The product of a force (applied in the direction of the motion of an object) and the distance the object moves.

2. Devices which combine two or more simple machines operating together.
3. The Law that states that energy cannot be created or destroyed.
6. Mechanical _____, The number of times that a machine increases or decreases the input force.
7. Nuclear _____The process that releases energy by splitting atomic nuclei apart.

13. Energy reflected or emitted from objects and travels through space in the form of waves.
17. Potential energy stored in an elastic object when it is stretched compressed or twisted.
18. The ability to do work.
