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