Across
- 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. A material in which charges cannot move freely
- 28. One of two points, such as the ends of a magnet, that have opposing magnetic qualities
Down
- 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 an electric current is on the coil
- 8. The force that resists the starting 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 a change in motion unless an outside forces acts on the object
- 15. The force of attraction or repulsion generated by moving or spinning electric charges
- 16. A element or compound that conducts electric current better than 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 that is 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 a object in order to change the motion of the object; force has size and direction.
- 24. A coil of wire with an electric current in it
