How does a pressure difference cause a force?
(Note that pressure on the front of the box pushes the box backwards, just as if you push on the front of your car, you are pushing it backwards.) A common situation in which this pressure difference occurs is a fluid in a gravitational field, such as the atmosphere or the ocean. In that case, the fluid itself is held up by the pressure difference.
