Vocab Choice board Physics

1. Electric charge at rest; generally produced by friction or induction.
3. A device that converts mechanical energy into electrical energy.
5. The motion of a body when only the force of gravity is acting on the body.
7. A region where a magnetic force can be detected.
8. A device that converts electrical energy into mechanical energy.
10. The combination of of all forces acting on an object.
11. A coil that has a soft iron core that acts as a magnet when an electric current is in the coil.
14. One of two points, such as the ends of a magnet, that have opposing magnetic qualities.
15. The force that opposes the movement of two surfaces that are in contact and are moving each other.
17. The force that resists the start of sliding motion between two surfaces that are in contact and at a rest.
19. The force of attraction or repulsion generated by moving or spinning electric charges.
21. The energy that an object has because of the position, condition, or chemical composition of the object.
22. Any material that attracts iron or materials containing iron.
23. An element or compound that conducts electric current better that an insulator does but not as well as a conductor does.
27. The tendency of an object to resist a change in motion unless an outside force acts on the object.
28. The path that a body follows as it travels around another body in space.

2. A device that increases the or decreases the voltage of alternating current.
4. A material in which charges cannot move freely.
6. The process of creating a current in a circuit by changing a magnetic field.
9. 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.
12. A material in which charges cannot move freely.
13. A push or pull exerted on an object in order to change the motion of the object; force has size and direction.
16. A coil of wire with an electric current in it.
18. The energy of an object that is due to the object’s motion.
20. A fundamental property that leads to the electromagnetic interactions among particles that make up matter.
24. A force of attraction between objects that is due to their masses .
25. Any region in which physical force has an effect.
26. 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.
