| dc.description | A small sphere placed on the top of a big static frictionless sphere, slips until it leaves the surface at an angle $θ_{l}=\cos^{-1}{2/3}$. On the other extreme, if the surface of the big sphere has coefficient of static friction, $μ_s\to\infty$, the small sphere starts rolling and continues to do so until it leaves the surface at an angle $θ_{l} =\cos^{-1}{10/17}$. In the case where, $0\leqμ_s<\infty$, we get a simple phase diagram. The three phases are pure rolling, rolling with slipping and detached state. One phase line separates pure rolling from rolling with slipping. This diagram is obtained when stopping angles for pure rolling are plotted against static friction coefficients $μ_s$. Study in this article is restricted to the case when the mobile sphere starts at the top of the static sphere with infinitesimal kinetic energy. | |
