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