Fjord is standing on the ceiling of a room, held by gravity-defying boots, observing a loose pen on the floor. If the pen starts floating upward towards him due to a sudden reversal in the room's gravity, how will the pen's orientation change as it floats from the floor towards Fjord? Provide a very brief response.
As the pen floats upward from the floor towards Fjord, its orientation relative to Fjord will remain the same unless acted upon by another force other than the reversed gravity. This means that if the pen was parallel to Fjord's body when on the floor, it will remain parallel as it floats up towards him. The pen's behavior is due to inertia, which is an object's resistance to any change in its state of motion. Since the pen was at rest on the floor, and no external rotational forces are applied, it will not rotate on its own as it moves towards Fjord.
