Across
  1. 3. Energy of position or height
  2. 4. The vibration and movement of molecules
  3. 6. Electromagnetic waves
  4. 9. Energy of movement (motion)
  5. 10. Stored in bonds of atoms and molecules
  6. 11. Movement of electrons
  7. 12. Vibration of waves through material
  8. 14. refers to the mechanical work that needs to be done against the forces that are holding an object together.
  9. 16. can be used to heat homes directly or to generate electricity.
  10. 18. Cannot be created or destroyed and can also transform from one form to another.
  11. 20. is the energy that is stored in elastic materials or objects (a rubber band, a spring, etc.)
Down
  1. 1. defined as the excess energy of the molecules at the surface of a material compared to the molecules within the material, and refers to the work (energy) required to build an area of a particular surface.
  2. 2. is a form of kinetic energy (angular kinetic energy) due to the fact that the object rotates, and the rotational energy is part of its total kinetic energy.
  3. 5. is an energy form of moving charge carriers (electrons)
  4. 7. is the conversion of solid fuel made from plant materials into electricity.
  5. 8. An object’s movement creates energy
  6. 13. Stored in the nucleus of an atom; released when nucleus splits or combines
  7. 15. Energy that is stored
  8. 17. is a form of renewable energy that uses the power of moving water to generate electricity.
  9. 19. the process by which the wind is used to generate mechanical power or electricity.
