7.7 CW 2

1. a circuit with more than one path for charges to travel
3. stored energy an object has because of its height and mass
5. the number of waves that pass a point in a certain amount of time
8. a circuit with only one path for charges to travel
9. the transfer of thermal energy from something warmer to something cooler
10. transfer of thermal energy by waves
11. transfer of thermal energy when particles bump into each other
14. how tall a wave is; bigger amplitude means the wave is carrying more energy
15. the distance from one wave to the next matching point, like crest to crest
17. a wave, like light, that can transfer energy without needing matter to travel through
19. a path that lets electricity move from a source to a device
22. the flow of electric charges through a circuit
23. the lowest point of a wave
24. the highest point of a wave
26. a change of energy from one form to another
28. stored energy caused by the position of charged particles

2. the idea that energy is not created or destroyed; it only changes form or moves somewhere else
4. how much a material or circuit slows down the flow of electric charges
6. the difference in electrical energy that pushes charges through a circuit
7. a wave that needs matter, called a medium, to travel
12. a complete path that allows charges to flow and transfer energy
13. a device that changes mechanical energy into electrical energy
16. the matter a mechanical wave travels through, such as air, water, or a solid
18. the energy connected to how particles move in matter
19. transfer of thermal energy when warmer fluids rise and cooler fluids sink
20. energy involved with motion or position that can move objects by pushes or pulls
21. a system that can exchange matter or energy with its surroundings
25. a broken path where charges cannot flow, so energy is not transferred
27. the object or group of objects being looked at as one whole
