|
states that like charges repel, or push away, and opposite charges attract.
|
|
|
electric force
|
The force between charged objects
|
|
|
electric field
|
the region around a charged object in which an electric force is exerted on another charged object
|
|
|
conductor
|
a material in which charges can move easily. Most metals are good conductors
|
|
|
insulator
|
a material in which charges cannot move easily. Insulators do not conduct charges very well because their electrons cannot flow freely
|
|
|
Static electricity
|
the electric charge at rest on an object.
|
|
|
electric discharge
|
The loss of static electricity as charges move off an object
|
|
|
friction
|
this happens when electrons are "wiped" from one object to another
|
|
|
induction |
happens when charges from an uncharged metal object are rearranged without direct contact
|
|
|
conduction |
happens when electrons move from one object to another by direct contact
