- 2. used up much faster than it can be replaced
- 6. energy that travels as waves through matter or through empty space
- 9. energy of moving objects (car moving)
- 11. energy from the sun
- 13. store electrical energy produced by solar cells
- 14. the energy of moving particles (hot cocoa has many)
- 16. energy of moving water
- 17. the ability to make things move or change
- 18. energy stored in the nucleus of an atom
- 19. solar cell can change light energy into electricity
- 20. an energy resource that formed over millions of years from decayed remains of plants and animals
Down
- 1. can be replaced as it is or cannot be used up
- 3. energy of moving air( wind turbines)
- 4. careful use of resources
- 5. reflects and forces sunlight onto a fluid pipe, thermal energy is used to create steam, which turns the turbine wind energy
- 7. any material from living things that can be used as an energy source
- 8. energy stored in the bonds that hold atoms together
- 10. heat energy from inside the earth that can be used to heat buildings and produce electricity
- 12. a change form one form to another
- 15. energy of moving charges (lamps, toasters)
