Across
- 8. any material that attracts iron and materials that contain iron
- 9. a coil of wire with an electric current in it
- 10. the force that opposes the movement of two surfaces that are in contact and are moving over each other
- 12. the region where a magnetic force can be detected
- 17. a device that converts mechanical energy into electrical energy
- 18. The interaction between electricity and magnetism
- 19. A fundamental property that leads to the electromagnetic interactions among particles that make up matter.
- 21. A push or pull exerted on an object in order to change the motion of the object
- 23. any region in which a physical force has an effect
- 25. The tendency of an object to resist a change in motion unless an outside force acts on the object
- 26. The combination of all forces acting on an object
- 29. 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
Down

- 2. A device that increases or decreases the voltage of alternating current
- 3. the force that resists the initiation of sliding motion between two surfaces that are in contact and at rest
- 4. the process of creating a current in a circuit by changing a magnetic field
- 5. the force of attraction or repulsion generated by moving or spinning electric charges
- 6. one of two points, such as the ends of a magnet, that have opposing magnetic qualities
- 7. the sum of an object's kinetic and potential energy due to gravity or elastic deformation
- 11. a coil that has a soft iron core and that acts as a magnet when an electric current is in the coil
- 13. A force of attraction between objects that is due to their masses.
- 14. the motion of a body when the only force of gravity is acting on the body
- 15. the energy an object has due to its motion
- 16. electric charge at rest; generally produced by friction or induction
- 20. the energy that an object has because of the position, shape, or condition, or chemical condition of the object
