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