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