Read the excerpt from A Black Hole is NOT a Hole. For example, imagine a fluffy snowball and a harder-
packed snowball of the same size. The fluffier ball is
made of less stuff. Its pull is wimpier than the pull of the
densely packed ball.
You can feel this difference when you hold the two
snowballs in your hands. Each one presses down on
your hand because of the gravitational attraction it
shares with Earth. The hard-packed snowball has a
stronger attraction to Earth because it is made of more
material. It presses more forcefully than the fluffy one. It
feels heavier
What do the differences in the two snowballs help the
reader understand about gravity?
Hard objects have a stronger attraction to Earth than
fluffy objects
Hard objects have a weaker attraction to Earth than
fluffy objects.
Heavy objects have a stronger attraction to Earth
than light objects
