The forces you're looking for do not come from contact joints, and/or are
not part of "rigid body" dynamics (e.g. grass).  But, you can fake it by
applying those forces yourself.

The rolling sphere thing comes up here often, AFAIK the usual solution is
to apply a force proprotional to its velocity.
