Opposites Attract
Factors that affect the electric field between 2 objects.
Charge, Distance
Occurs when 2 objects are rubbed together, causing a transfer of electrons between the objects.
friction
A material through which charges can move freely.
Conductor
An object that has a positive charge equal to its negative charge
neutral
Positively charged ions have
more protons than electrons
Any 2 charged objects exert a force on each other
electric force
A build up of electric charges on an object.
Static Electricity
a material through which charges cannot move easily.
Insulator
The electrons lost by one object are ___________ by another.
gained
Negatively charged ions have
fewer protons than electrons
has a negative charge
electron
A Generator that places a charge on its dome and uncharged objects that touch the dome becomes charged by contact.
Van de Graaff generator
A special class of materials that conduct electric charge better than electrical insulators but not as well as electrical conductors.
Semiconductors
Like charges
repel
Dense center of an atom
nucleus
Has a positive charge
proton
The loss of charges
electric discharge
the purpose of the material surrounding the metal inside a lamp cord.
insulate( prevent shock)
Opposite charges
attract
2 parts of the nucleus
protons and neutrons
has no charge
neutron
The way of rearranging the charges within an object without touching it.
Induction
Iron , metal, copper wire
conductors
Atom has an overall positive or negative charge
ion
Found outside of the nucleus
electrons
