I did not create this little picture but it is interesting to say the least. It is a physics question or scenario, i don't know how to describe it but would love the input of the physics forum community. Which do you think would happen? A or B? Background info. This is from a game called portal. Pretty simple. What goes into the orange portal comes out the blue portal. The question here in the picture is would the velocity of the downward portal transfer to the cube if the cube is not moving. That may not even be a right way to describe it but look up some youtube videos if you need more information on how they work.
