Depth and slip ratio dependencies of friction for a sphere rolling on a granular slope
Takeshi Fukumoto, Hiroyuki Ebata, Ishan Sharma +1
We experimentally investigate the dynamics of a sphere rolling down a granular slope by varying the initial velocity, slope angle, and sphere density. The results show that the sph…

Energy dissipation of a sphere rolling up a granular slope: slip and deformation of granular surface
Takeshi Fukumoto, Ken Yamamoto, Makoto Katsura +1
We experimentally investigate the dynamics of a sphere rolling up a granular slope. During the rolling-up motion, the sphere experiences slipping and penetration (groove formation)…
