Flashcards in 10.1 Deck (13):
1

Electric charges

Charged particles that exert an electric force on each other

2

Static electricity

Aka static charge
An electric charge that builds up on he surface of an object. The charge is bound to the surface and. Cannot move until it is given a path to escape

3

Friction

An opposing force that resists the relative motion of two objects

4

Electron affinity

The tendency of an object to hold onto electrons

5

Law of attraction

Particles with opposite charges attract each other

6

Law of repulsion

Particles with the same charge repel each other

7

Coulomb C

Unit for an electric charge
Otis equal to 6.24 times 10^18 electrons added to or removed from a neutral object

8

Conductivity

The ability of objects to allow electrons to move freely in them

9

Insulator

Is a solid liquid or gas that blocks the movement of electrons
Ex
Pure water
Wood
Plastic
Rubber
Metal oxides like rust

10

Conductors

Materials that allow the movement of electrons and allow them to change position
Ex
Copper
Aluminum
Iron
Mercury
Other metals

11

Conduction

The movement of transmission of electrons through a substance

12

Semi conductors

Aka fair conductors
Materials that allow electrons to somewhat move but not as freely as in a Conductor
Ex
Water with dissolved minerals
Moist air
Human body
Carbon
Soil

13

Triboelectric series

A list of materials ranked from those most likely to lose electrons to those most likely to gain electrons
