Surfaces which are rough create the most friction. Like cement, or sand paper.
Friction is the resistance that one object or surface encounters when it moves against another object. The surfaces that exhibit the most frictional force are rough surfaces.
Surface area works like this. The slicker something is, the less friction. Ice has less friction than an asphalt road. Hope this answers your question.

How does surface roughness affect friction?
answer it yourself ;)
The amount of friction depends on what?
Friction depends on the surface that the object is going against. If an applied force is used to push a box on a ground, the friction is the surface of the ground, may the ground be rough or smooth, there is a force that goes against the applied force. Air friction is also a type of friction that many physics question does not account for, because it is a virtually small force.
What kind of friction is wheels rolling on a car?
kinetic friction, and this motion creates thermal energy from this friction. However the wheels moving on a car is directly created from the work of a combustion engine which creates multiple types of friction, chemical and thermal are the two major types.
Examples of high friction?
Example of high friction is a really rough surface like sandpaper.
Force that opposes motion of surface as it moves across another surface?
the force that opposes the motion of two touching surfaces is velocity.
What surface creates less friction?
A smooth surface typically creates less friction compared to a rough surface. Friction is influenced by factors like surface texture, smoothness, and the materials involved, with smoother surfaces allowing objects to slide more easily over them.
What surfaces create most friction?
Rough surfaces with high levels of texture create the most friction. This includes surfaces like sandpaper, concrete, and surfaces covered in gravel or rocks. The greater the roughness and irregularity of the surface, the more friction is generated when objects slide against it.
The force that opposes the motion of an object moving on a surface?
The force that opposes the motion of an object moving on a surface is called friction. Friction occurs due to the interaction between the surfaces of the object and the surface it is moving on, which creates resistance to motion.
What can be used to reduce sliding friction and why?
A lubricant such as oil or wax, because it creates a smoother surface to slide on.
How does burning rubber create friction?
When rubber is burned, it produces a thin layer of residue on the surface of the tire. This residue can create friction when it comes into contact with the road, as it acts as a gripping agent between the tire and the road surface. As a result, the friction between the tire and the road helps to create traction, which is essential for vehicle control and braking.
How does a surface affect friction?
A rough surface typically creates more friction compared to a smooth surface due to the increased contact points between the two surfaces. The roughness of a surface can create interlocking grooves and bumps, leading to a stronger resistance to motion. Conversely, a smooth surface allows for less resistance, resulting in lower friction.
What kind of stream bed would cause the most friction?
A rocky stream bed with large, irregularly shaped rocks would cause the most friction for water flowing over it. The rough surface of the rocks creates turbulence and resistance, slowing down the water flow.
Does gravel have friction?
Yes, gravel does have friction because of the rough and irregular surface of its individual particles. When objects move across gravel, the contact between the particles and the object creates resistance, which we perceive as friction.
Most force must be applied when pushing something across a rough surface?
When pushing something across a rough surface, you need to apply more force because the rough surface creates more friction between the object and the surface. This increased friction resists the motion of the object, requiring more force to overcome it. The rougher the surface, the more force is needed to move the object.
How does low air pressure in bicycle tires reduce the efficiency of the bicycle?
Flabby tyres produce more friction with the road.Less air pressure creates more surface friction, the less surface friction there is the better. (Example look at the very skinny narrow tyres on road racers as they don't need a lot of surface friction while mountain bikes have thick tyres as they need more friction)
Why is scraping your knees a harmful friction?
Scraping your knees creates friction between the skin and the surface you are in contact with. This friction generates heat and can damage the outer layer of the skin, leading to pain, inflammation, and the risk of infection.
How does the roughness of a surface effect friction?
A rough surface will have more contact points with another surface, increasing friction compared to a smooth surface due to greater interlocking of surface asperities. This increased frictional force is a result of the energy required to overcome the roughness and microstructures of the surfaces when they slide past each other.
