A. The type of material of a horizontal surface can affect the force of static friction by changing the roughness or smoothness of the surface. A rougher surface will typically have a higher force of static friction because there will be more resistance to motion.
B. The force of kinetic friction is also affected by the type of material of the horizontal surface. A rougher surface will typically have a higher force of kinetic friction because there will be more resistance to motion once the object is already in motion.
C. The coefficient of static friction is a ratio that represents the force of static friction between two surfaces. The type of material of the horizontal surface will affect the coefficient of static friction by determining how rough or smooth the surface is and thus how much force is required to overcome static friction.
D. The coefficient of kinetic friction is also affected by the type of material of the horizontal surface. A rougher surface will typically have a higher coefficient of kinetic friction because there will be more resistance to motion once the object is already in motion.

A. force of static friction
B. force of kinetic friction
