Energy

7. Force exerted on an object that causes it to move, change position or direction.
8. Energy caused by an object's vibrations
10. Energy in the form of moving waves, rays, or particles.
12. Energy caused by the movement of electrons.
14. The potential energy caused by a strong nuclear force.
15. The potential energy of an object that is stretched or compressed.
16. The energy stored in the chemical bonds of a substance.
17. A natural resource of energy that can be replaced at the same rate at which the resource is consumed.
18. The ability to do work or cause change.

1. Energy stored by objects due to their position above Earth's surface.
2. The energy an object has due to its motion.
3. Stored energy that results from the position, shape or composition of an object.
4. Energy cannot be created or destroyed; it may be transformed from one form into another, but the total amount of energy never changes.
5. Energy stored in the movement of objects. The faster they move, the more energy is stored.
6. An energy resource that cannot be replaced.
9. The range of wavelengths or frequencies over which electromagnetic radiation extends.
11. The amount of work an object can do because of the object's kinetic and potential energies.
13. Energy that comes from the movement of atoms or molecules.
