Energy
Across
- 3. energy cannot be created or destroyed it can only change forms
- 4. the ability to do work
- 5. the transfer of energy as heat by the movement of a liquid or gas
- 7. the number of waves that pass a point in a given amount of time, usually one second
- 10. the time required for identical parts of consecutive waves to pass a given point
- 11. when energy changes from one form to another
- 13. equal to the amount of energy needed to raise the temperature of 1 g of water by 1 degree C
- 15. a measure of how far particles in the medium move from their rest position
- 18. vibrations of electric and magnetic fields
- 20. the speed that waves travel depends n the properties of the medium
- 21. a material that is a poor conductor of energy as heat
- 22. the energy transferred from an object at a higher temperature to an object at a lower temperature
Down
- 1. the total kinetic energy of all of the particles in a substance
- 2. the rate at which work is done
- 3. particles move back and forth in the same direction that the wave travels
- 6. waves that require a medium
- 8. particles move perpendicularly to the direction the wave travels
- 9. a material that transfers heat as energy very well
- 12. the ratio of useful output energy to input energy
- 13. the transfer of energy as heat through matter by direct contact
- 14. the transfer of energy by electromagnetic waves
- 16. the use of force to move an object some distance
- 17. the distance from any point on a wave to the next identical point on the same wave
- 19. the material through which a wave can travel
