Across
- 1. closed conducting loop through which an electric current can flow.
- 3. charged particle that has either more or fewer electrons that protons
- 5. rate at which electrical energy is converted to another form of energy; expressed in watts (W).
- 9. tendency of an object to resist any change in its motion
- 12. material, such as copper wire, through which electrons can move easily.
- 13. total distance an object travels divided by the total time it takes to travel that distance.
- 15. force that opposes the sliding motion between two touching surfaces.
- 16. factor that, as it changes, affects the measure of another variable
- 18. factor that changes as a result of changes in the other variable.
- 19. ability of a fluid, which include liquids and gases, to exert an upward force on an object immersed in it.
- 20. material in which electrons and thermal energy are not able to move easily
Down
- 1. transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from one place to another.
- 2. ratio of the output work done by the machine to the input work done on the machine, expresses as a percentage.
- 4. possible explanation for a problem using what is known and what is observed.
- 6. electric current that reverses its direction of flow in a regular pattern.
- 7. energy that is transferred between objects due to a temperature difference between those objects.
- 8. device that uses electromagnetic induction to convert mechanical energy to electrical energy.
- 10. rate of change of velocity; can be calculated by dividing the change is the velocity by the time
- 11. electric current that flows in only one direction.
- 14. the net movement of electric charges in a single direction, measured in amperes (A).
- 17. state in which forward and reverse reactions or processes occur at equal rates.
