electrostatic
positive and negative charges
like charges repel
unlike charges attract
gain electrons
negatively charge
lose electrons
positively charge
one is charges but other obj is not, they attract
the closer the charges, the greater the force between them
rubbing materials (friction) only separates charges, not make them
static electricity
electric charge that stays in one place
insulators
do not allow electric charges to pass through them
can become charged when rubbed together
can store charges
electrons have a negative charge
a charged object does not have an equal amount of negative and positive charge
define: the result of an imbalance between negative and positive charges
conductors
cannot hold electric charge
let electric charges pass through
perspex rods
electrons transferred from cloth to the rod
negatively charged
by friction and contact
polythene rods
#
electrons are transferred from the rod to the cloth
positively charged
