[DCU] How is the Flash landing on the ground different from running up a wall?

I'm not particularly familiar with the comic lore, but I would like any answer to be based in the comic cannon (any of them). I'm a superhero newbie, only really having knowledge about some of the TV shows and movies, as well as some late night Googling to trying and piece things together.

Something that has always bothered me in the shows is when the Flash is shown to be in peril when free falling. I am aware in the comics that the Flash can achieve a soft landing by rotating his arms quickly to create mini tornadoes. I am also aware that he has been show to be able to control his movement in the air to a degree, even running on ice crystals in the stratosphere.

No, what I want to know is how the Flash having his momentum completely arrested in the downwards direction after a fall is any different from him coming to an instantaneous stop when running or his change in velocity when running into and then up a wall.

Thanks.

The innate human terror of falling is one of those kinds of things that's sufficiently deeply ingrained that it becomes difficult to consciously use the Speed Force to slow one's descent. Deliberately redirecting your momentum by changing direction is a little easier to wrap the ol' primitive monkey-brain around.
