Across
- 2. bottom of the wave
- 3. moves perpendicular to the direction of the wave
- 5. compression waves of high and low pressure
- 9. moves parallel to the wave motion
- 14. an object propelled through the air horizontally or at an angle
- 15. top of the wave
- 17. a quantity having direction as well as magnitude
- 18. a push or pull on an object
Down
- 1. electricity passes through very easily
- 4. resists current flow, measured in Ohms
- 6. the height of the wave from equilibrium to crest
- 7. mass times velocity
- 8. flows through circuits, measured in amps
- 10. pushes electrons, measured in volts
- 11. a force that opposes motion
- 12. energy that is moving
- 13. a= -9.81m/s squared
- 16. number of waves that pass a point in a given amount of time
