This guy's momentum vector is balanced over his edge. Centrifugal force doesn't exist, and neither do double fall lines. They are illusions. Anyway...

Inclination is the angle between your weight vector (vertical) and the vector formed by connecting your center of mass to the board. Without the jargon, it means leaning into your turns. You can make heavy use of inclination if the surface is consistent and edgeable (groomers). On ice, moguls, icy moguls, powder, or any variable conditions, inclining your body relative to vertical frequently makes you fall. Angulation is articulating the joints in the body to create edge pressure/edge angle while keeping the body vertical. In the photo, the guy's upper body is nearly vertical. He is using a combination of lots of inclination and lots of angulation. Using angulation allows him to make shorter radius turns, since only his legs (rather than his whole body) need to change their momentum and orientation to the hill to make the board change edges.

No wipeout because f x sin A =mass x gravity . I hope this translates.
