Friction is greatest in the absent of lubrication. This happens when two objects rub against each other and this might be useful or harmful depending on the set up.
A. Static friction has the greatest strength among the three types of friction—static, sliding, and rolling. Static friction is the force that resists the initiation of sliding motion between two surfaces in contact.
Static friction typically has more friction than kinetic friction. Static friction occurs when an object is not moving, and the friction force is at its maximum to prevent the object from moving. Once the object overcomes static friction and starts moving, the friction force decreases to kinetic friction.
I would expect a rough surface to have the greatest amount of friction due to the increased contact points between the surfaces, resulting in a higher resistance to motion. Smooth surfaces typically have less friction due to reduced contact points.
Rough surfaces typically produce the greatest amount of friction because there are more contact points between the surfaces, leading to increased resistance to motion.Smooth surfaces, on the other hand, tend to have less friction due to reduced contact points and smoother interactions between surfaces.
The greatest acceleration a runner can generate is limited by the static friction force, which is given by the product of the coefficient of static friction and the normal force. If the coefficient of static friction is 0.95, then the maximum acceleration would be 0.95 times the acceleration due to gravity (9.81 m/s^2), which equals 9.31 m/s^2.

Solids that are actually glued, or better yet soldered, together.
A falling object has the greatest potential energy when it is highest, at the beginning of the fall. It has the greatest kinetic energy when it is at its lowest, at the end of the fall. Without taking friction or air resistance into account, the beginning potential energy is the same as the final kinetic energy. If friction is considered, the beginning potential energy is greater.
Because the frictional force must be greater than forces that would cause the object to move. Example: a car parked on a slope does not move despite the force of gravity acting to pull it down the hill. Why? Because the frictional forces are greater than the forces of gravity.
i think it it rolling friction
Static friction
The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.
