2. A material in which charges cannot move freely.
4. 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.
6. The interaction between electricity and magnetism.
10. Any region in which a physical force has an effect.
11. 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.
13. The energy that an object has because of the position, condition, or chemical composition of the object.
14. A device that increases or decreases the voltage of alternating current.
16. Electric charge at rest; generally produced by friction or induction.
21. The force that opposes the movement of two surfaces that are in contact and are moving over each other.
25. A force of attraction between objects that is due to their masses.
26. A material in which charges can move freely.
27. The process of creating a current in a circut by changing a magnetic field.
28. One of two points, such as the ends of a magnet, that have opposing magnetic qualities.

1. A fundamental property that leads to the electromagnetic interactions among particles that make up matter.
3. A device that converts mechanical energy into electrical energy.
5. Any material that attracts iron or materials containing iron.
7. A coil that has a soft iron core and that acts as a magnet when a electric current is in the coil.
8. The force that resists the start of sliding motion between two surfaces that are in contact and at rest.
9. The combination of all of the forces acting on an object.
12. The tendency of an object to resist change in motion unless an outside force acts on the object.
15. The force of attraction or repulsion generated by moving or spinning electric charges.
16. An element or compound that conducts electric current better than an insulator does but not as well as a conductor does.
17. The motion of a body when only the force of gravity is acting on the body.
18. A region where a magnetic force can be detected.
19. A device that converts electrical energy into mechanical energy.
20. The energy of an object due to the object’s motion.
22. The path that a body follows as it travels around another body in space.
23. A push or a pull exerted on an object in order to change the motion of an object; force has size and direction.
24. A coil of wire with an electrical current in it.
