(a) The type of material of a horizontal surface can affect the force of static friction by changing the coefficient of static friction. Different materials have different coefficients of static friction, which determines how much force is required to overcome the friction when trying to move an object on the surface.
(b) The type of material of a horizontal surface can affect the force of kinetic friction in a similar way to static friction. Different materials have different coefficients of kinetic friction, which determines how much force is required to keep an object moving at a constant velocity on the surface.
(c) The type of material of a horizontal surface directly affects the coefficient of static friction. For example, rubber typically has a higher coefficient of static friction compared to plastic and wood.
(d) The type of material of a horizontal surface also directly affects the coefficient of kinetic friction. Again, different materials have different coefficients of kinetic friction, which determines how easily an object can continue moving on the surface once it is in motion.
