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