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?
What do you mean by adhere? Are you saying the sphere is sticky and sticks to the surface?
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 interested in exactitude as I am in giving the scene an authentic feeling.
