A. Force of static friction: 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 rough surface will typically have a higher force of static friction because there are more irregularities for the object to grip onto.
B. Force of kinetic friction: Similar to static friction, the type of material can also affect the force of kinetic friction by changing the roughness or smoothness of the surface. However, the force of kinetic friction is typically less than the force of static friction as the object is already in motion.
C. Coefficient of static friction: The coefficient of static friction is a measure of how much force is needed to start an object moving on a surface. The type of material can affect the coefficient of static friction by changing the roughness or smoothness of the surface, as well as any other properties of the material that may affect friction.
D. Coefficient of kinetic friction: The coefficient of kinetic friction is a measure of how much force is needed to keep an object moving at a constant speed on a surface. The type of material can affect the coefficient of kinetic friction in the same ways as static friction, but may also be influenced by factors such as the lubrication or temperature of the surface.
