How Objects become Charged
Physical Science - Middle School
❮

There
are
several
ways
that
an
object
can
become
charged,
and
electrons
can
be
transferred.
Friction
is
the
transfer
of
electrons
between
two
uncharged
objects
that
are
rubbing
against
each
other.
Induction
is
the
movement
of
electrons
within
an
object
in
response
to
an
electric
field
of
a
charged
object
nearby.
The
electrons’
movement
creates
a
charge
in
a
certain
area
of
the
object.
Static
Electricity
Static
electricity
occurs
when
electric
charges
build
up
on
an
object,
but
the
electrons
do
not
flow.
Static
electricity
is
what
causes
lightning.
An
excess
of
positive
charges
builds
up
on
the
ground
while
a
large
number
of
negative
charges
builds
up
in
the
clouds.
At
a
certain
point,
the
difference
between
the
negatively
charged
cloud
and
the
positively
charged
ground
is
so
great
that
the
static
electricity
turns
into
an
electrical
current.
The
bolt
of
lightning
is
actually
a
discharge
of
electrons
traveling
at
the
speed
of
light
toward
the
positive
charges.
Electroscope
An
electroscope
is
an
instrument
used
to
detect
charged
particles.
It
has
a
long
metal
rod
with
a
knob
on
top
and
two
metal
leaves
attached
to
the
bottom.
The
leaves
hang
straight
down
if
the
electroscope
has
no
charge.
If
a
charged
object
touches
the
knob
and
electrons
are
transferred,
the
metal
leaves
become
charged.
Because
the
leaves
are
the
same
charge,
they
repel
each
other
and
spread
apart.
The
leaves
will
move
in
the
presence
of
a
negative
or
positive
charge.
Conduction
is
the
transfer
of
charges
when
a
charged
object
is
in
direct
contact
with
another
object.

In
the
1700s,
Benjamin
Franklin
studied
lightning
and
electricity.
He
invented
the
lightning
rod
to
protect
buildings
during
storms.
