As the surface in contact are made rough, interaction between the surfaces is more established and hence the coefficient of friction between two surfaces increases.
The force of static friction tries to stop the body from moving, so it will act in a direction opposite to the applied force(moving will be due to the applied force. Friction always resist relative motion)
The coefficient of rolling resistance is generally much smaller than the coefficient of sliding friction.
The coefficient of friction between wood and wood is around 0.25-0.5 (static) & 0.2(kinetic). Every coefficient of friction is always less than or equal to one. (Only static friction coefficient in Rubber on Concrete is 1).
