Across
  1. 3. A material in which charges cannot move freely.
  2. 4. The energy that an object has because of the position, condition, or chemical composition of the object
  3. 5. The force of attraction or repulsion generated by moving or spinning electric charges.
  4. 7. A region where a magnetic force can be detected.
  5. 9. One of two points, such as the ends of a magnet that have opposing magnetic qualities.
  6. 11. A device that increases or decreases the voltage of alternating current.
  7. 14. The tendency of an object to resist a change in motion unless an outside force acts on the object.
  8. 15. A coil that has a soft iron core and that acts as a magnet when an electric current is in the coil.
  9. 18. The process of creating a current in a circuit by changing a magnetic field
  10. 20. A device that converts mechanical energy into electrical energy.
  11. 21. A coil of wire with an electric current in it.
  12. 23. Any region in which a physical force has an affect.
  13. 25. The sum of an object’s kinetic energy and potential energy due to gravity or elastic deformation; does not include chemical energy or nuclear energy.
  14. 26. A force parallel to the velocity of the flow; it opposes the direction of an aircraft and, in combination with thrust, determines the speed of the aircraft
  15. 27. The interaction between electricity and magnetism
  16. 28. Electric charge at rest; generally produced by friction or induction.
  17. 29. The force that opposes the movement of two surfaces that are in contact and are moving over each other.
Down
  1. 1. A material in which charges can move freely.
  2. 2. The path that a body follows as it travels around another body in space.
  3. 6. The force that resists the start of sliding motion between two surfaces that are in contact and at rest.
  4. 8. A fundamental property that leads to the electromagnetic interactions among particles that make up matter.
  5. 10. An element or compound that conducts electric current better than an insulator does but not as well as a conductor does.
  6. 12. Any material that attracts iron or materials containing iron.
  7. 13. The combination of all of the forces acting on an object.
  8. 16. The motion of a body when only the force of gravity is acting on the body.
  9. 17. The energy of an object that is due to the object’s motion.
  10. 19. A push or a pull exerted on an object in order to change the motion of an object; force has size and direction.
  11. 22. A device that converts electrical energy into mechanical energy.
  12. 24. A force of attraction between objects that is due to their masses.
