Say you set up an experiment with an inclined plane, and a cylinder rolling down the plane. Let's also let the experiment happen in a vacuum, such that there is no air friction.
However, let there be friction between the surface of the incline and the cylinder.
My questions related to this are;
does the cylinder accelerate forever? or does the cylinder have a terminal velocity? Does the cylinder keep rolling forever, or is it the case that, at some point, it starts slipping?
