Unit 6 physics Vocab

1. motion of a body when only the force of gravity is acting on the body
2. interaction between electricity and magnetism
5. A material in which charges cannot move freely
6. A device that converts mechanical energy
7. The force that resist the start of sliding motion between two surfaces that are in contact and at rest
9. The force that opposes the movement of two surfaces that are in contact and are moving over each other
13. 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
16. charge at rest generally produced by friction or induction
19. A material in which charges can move freely
20. material that attracts iron or materials containing iron
23. The tendency of an object to resist a change in motion unless an outside object acts on the force
24. The energy that an object has because of the position condition or chemical composition of the object
25. The combination of all of the forces acting on an object
26. A coil of wire with an electric current in it

1. Any region in which a physical force has an effect
3. A region where a magnet force can be detected
4. process of creating a current in a circuit by changing a magnetic field
8. energy of an object that is due to the object's motion
10. A device that increases or decrease the voltage of alternating current
11. A device that converts mechanical energy into electrical energy
12. coil that has a soft iron core and that acts as a magnet when an electric current is in the coil
14. The path that a body follows as it travels around another body in space
15. element or compound that conducts electric current better than an insulator does but not as well as a conductor does
17. A fundamental property that leads to the electromagnetic interactions among particles that make up matter
18. 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
21. A push or pull exerted on an object in order to change the motion of the object force has size and direction
22. A force of attraction between objects that is due to their masses.
