If the physics parameters are well set and contacts are reliable (cfm, iters, object mass), then the friction Gazebo uses it the static coulomb friction of force

F_f = F_N *mu

where F_N is the normal force the object pushes on the ground and mu is the lower oh the mu of the both interacting surfaces.

where F_N is the normal force the object pushes on the ground and mu is the lower oh the mu of the both interacting surfaces. F_f is the force needed to overcome the friction and make object slide over the surface.
