Abstract
The different states of a ball on a rough inclined plane are analyzed
from experimental results and numerical simulations. The conditions of
static equilibrium are given. The control parameters are the inclination
angle of the plane and the surface roughness. Then, we propose a
"phase diagram" for the motion of the ball. These results are
expected to be useful in understanding the origin of the segregation
effects on the surface of a sandpile.
