The type of material of a horizontal surface can affect the following parameters as follows:
(a) Force of static friction: The force of static friction depends on the nature of the surfaces in contact and their roughness. Different materials have different levels of roughness and surface characteristics that can affect the force of static friction. For example, a rough surface may have a higher force of static friction compared to a smooth surface.
(b) Force of kinetic friction: Similar to the force of static friction, the force of kinetic friction also depends on the materials in contact and their surface conditions. Different materials can have different coefficients of kinetic friction, which may affect the force of kinetic friction experienced.
(c) Coefficient of static friction: The coefficient of static friction is a measure of how difficult it is to get an object to start moving when resting on a surface. The type of material of the horizontal surface can affect the coefficient of static friction due to variations in surface roughness, chemical composition, and other factors.
(d) Coefficient of kinetic friction: The coefficient of kinetic friction is a measure of the resistance a moving object encounters when in contact with a surface. The type of material of the horizontal surface may affect the coefficient of kinetic friction due to variations in surface properties and how they interact with the moving object.
