Opposites Attract
is an invisible region around any charged object where an electric force is applied.
Electric field
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
The quantity of electricity held in an object.
electric charge
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
The only part of the atom that is moving is
electron
rubber, plastic, wood
insulators
Like charges
repel
Center of an atom
nucleus
Has a positive charge
proton
An object can be charged by touching it with another object that already has a charge.
conduction
the purpose of the material surrounding the metal inside the wire.
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
are tiny particles that make up all the matter around you.
Atoms
Found outside of the nucleus
electrons
