Static electricity |
The electric charge that builds up on a surface of an object. They remain nearly fixed in one location until they are given a path to escape. |
|
|
Electric charges |
Charged particles that exerts an electric force on each other. |
|
|
The types of charges |
Neutral, negative, positive (depending on their amount of electrons, protons, and neutrons) |
|
|
Friction |
The force of resisting the relative motion of two surfaces in contact. One object loses electrons to transfer to the other which gains them. Both objects are neutral at the beginning. |
|
|
Electron affinity |
The tendency of a substance to hold on to the electrons. The higher the object, the greater tendency for a material to lose electrons = positive and lower is gains electrons = negative |
|
|
Law of attraction |
The Law of Attraction states that particles with opposite charges attract each other |
|
|
Law of repulsion |
The law of motion states that particles of like charges repel each other |
|
|
Conductivity |
The ability of a material to allow electrons to move freely in them. Copper aluminum Iron and Metals |
|
|
Electric insulator |
A solid liquid or gas that resists or blocks the movement of electrons. Can hold static charges because they remain nearly fixed in place. |
|
|
Conductor |
Materials that allow electrons to change positions (eg.copper) |
|
|
Fair conductor |
Electrons do not move as freely as in connectors but are not held in place as insulators (eg. Water with minerals) |
|
|
Insulator |
Don't conduct electricity |
