Investigate the attractive
forces of gravity and show that these attractive forces depend on the mass of
the interacting objects. In the first
part of the experiment, students depict gravity using the concept of gravity
wells, which visually show the pull or depth of gravity that an object exerts
in space. In the second part of the
experiment, students will investigate how the mass and size of objects falling
to the earth due to gravity can affect the depth and size of a crater. Using the equation for force, F=MA, students
will demonstrate using calculations that force is proportional to the mass of
the objects.
