Unit 1 Review
Across
- 1. an instrument that uses a freely moving magnetic needle to indicate direction.
- 4. energy that an object has because of its motion or its position
- 5. the energy an object has while in motion
- 8. a type of magnet in which the magnetic field is produced by an electric current. (usually contains a wire wound into a coil).
- 10. the energy an object stores while at rest
- 13. a material electrons/energy do not moves easily through
- 14. any material capable of attracting iron and producing a magnetic field.
- 15. a device that transforms mechanical energy into electrical energy.
- 17. a conductive loop that allows charged particles to continually move through it.
- 18. the ability to do work or cause change; the ability to move an object some distance
- 20. energy stored as a result of applying a force to deform an elastic object.
- 21. a conductive loop with an opening which does allow the particles to move
- 22. energy in the form of charged particles
Down
- 1. energy that is stored in the bonds between atoms
- 2. the energy an object has as a result of its location above the earth’s surface
- 3. energy that does not need matter to travel; light; sun (solar)
- 6. either of two opposing forces or parts, such as the poles of a magnet (n & s).
- 7. energy in the form of heat
- 9. a material electrons/energy moves easily through
- 11. an invisible field around a magnet.
- 12. a property of certain kinds of materials that causes them to attract iron or steel.
- 16. to push away, as similar poles of two magnets push away from one another.
- 18. current the number of electrons that pass a given point in a certain amount of time - ampere (a)
- 19. a conductive loop with an opening which doesn’t allow the particles to move
