Potential
energy
is
____________________
energy
available
to

____________________
.
Gravitational
potential
energy
is
stored
energy
due
to
____________________
or
____________________
of
mass
while
elastic
potential
energy
is
stored
energy
due
to
____________________
or
stretching
or
compressing
.
Work
done
can
be
found
by
using
the
equation
____________________
____________________
=
____________________
x
____________________
in
the
direction
of
the
force
.
We
know
that
Force
due
to
gravity
,
or
weight
,
is
____________________
=

.
We
also
know
that
work
done
is
equal
to
force
x
distance
.
Therefore
,
we
can
derive
the
equation
for
potential
energy
changes
near
the
Earth's
surface
:
