Two graphs show the (horizontal and vertical) position, velocity and forces on the bouncing ball change with time.

Can you explain the relationship between force, velocity and position in each graph?
Is there any relationship between the two graphs?
Why is this - and what might happen in reality?

Note: the force felt by the ball on collisions has been averaged out in the graphical display - so that it is displayed as being smaller but lasting longer than it really does.
