Across
  1. 2. Stored energy that depends upon the relative position of various parts of a system.
  2. 3. A trait or property that comes from electromagnetic forces and fields.
  3. 4. Materials with high resistivity
  4. 5. A device that transfers electrical energy from one alternating-current circuit to one or more other circuits, either increasing or reducing the voltage.
  5. 7. Attraction or repulsion arises between electrically charged particles because of their motion.
  6. 10. The physical interaction among electric charges, magnetic moments, and the electromagnetic field.
  7. 11. A long thin loop of wire often wrapped around a metallic core, which produces a magnetic field when an electric current is passed through it.
  8. 12. The motion of a body when only the force of gravity is acting on the body.
  9. 14. A device used to convert electricity into mechanical energy.
  10. 15. The combination of all of the forces acting on an object.
  11. 20. Friction The force that opposes the movement of two surfaces that are in contact and are moving over each other.
  12. 22. The result of an imbalance between negative and positive charges in an object.
  13. 25. 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.
  14. 26. A force of attraction between objects that is due to their masses
  15. 27. A regular repeating path that one object in space takes around another ones.
  16. 28. A substance or material that allows electricity to flow through it.
  17. 29. Any machine that converts mechanical energy to electricity for transmission and distribution over power lines to domestic, commercial, and industrial customers.
Down
  1. 1. The creation of an electromotive force by way of a moving magnetic field around an electric conductor.
  2. 6. Region at each end of a magnet where the external magnetic field is strongest.
  3. 8. The energy of either an object in motion or the energy that is stored in objects by their position.
  4. 9. Any material capable of attracting iron and producing iron and producing a magnetic field outside itself.
  5. 13. A type of physical interaction that occurs between electrically charged particles.
  6. 16. Any region in which physical force has an effect.
  7. 17. Friction The force that resists the start of sliding motion between two surfaces that are in contact and at rest.
  8. 18. A push or a pull is exerted on an object in order to change the motion of the object; force has size and direction.
  9. 19. Materials have a conductivity between conductors and nonconductors or insulators.
  10. 21. The tendency of an object to resist a change in motion unless an outside force acts on the object.
  11. 23. The energy an object has because of its motion
  12. 24. The region around a magnetic material or a moving electric charge within which the force of magnetism acts.
