Figure

shows
a
moon
and
two
ring
particles.
The
inner
ring
particle
will
have
a
slightly
higher
speed
than
the
moon,
as
indicated
by
the
longer
arrow
in
the
direction
of
its
orbit,
and
the
outer
ring
particle
will
have
a
slightly
slower
speed
than
the
moon,
as
indicated
by
the
shorter
arrow
in
the
direction
of
its
orbit.
The
moon
will
have
a
strong
gravitational
effect
on
both
ring
particles.
