I realize that. The surface is only *slightly* less than vertical. What I'm asking is, what specific forces are at work?

Thanks for replying. No, not sticky in the standard sense of the word. I was hoping there might be physical forces at work while the sphere was rolling that would make it less likely to depart from the surface -- if only for a few seconds. This is for a work of fiction, so I'm less...

What force(s) are at work when a spherical object, rolling down an angled surface, tends to adhere to the surface, if only for a short while? Does such a thing exist or am I playing fast and loose with the laws of nature? Thanks
