Surfaces that are rough have more contact points at the microscopic level, which creates more resistance when they come into contact with each other. This increased contact area leads to more interactions between the surfaces, resulting in higher frictional forces compared to smoother surfaces.
What else can I help you with?
When friction is greater when surface have more is it gravity or roughness?
Both. Suppose you want to move something over the ground. If it becomes heavier then it will be subject to more friction on account of gravity. If it's lower surface becomes rougher then again, it will be subject to more friction. The force pressing two surfaces together and the roughness of the two surfaces act together to produce friction.
What happens to friction when there is a rougher surface?
Friction increases when a surface is rougher because there are more contact points between the two surfaces, leading to a greater resistance to sliding. This results in higher friction forces being generated between the surfaces.
How does the roughness of surfaces that are touching affect the friction betwen the surfaces?
Rough surfaces will have more contact points, creating more friction due to the increased resistance between the surfaces. Smoother surfaces have less contact points, resulting in lower friction because there is less resistance between the surfaces.
What surfaces would have the highest coefficient of friction?
Surfaces with a high coefficient of friction include rubber on concrete, sandpaper on wood, or a shoe sole on carpet. Typically, surfaces that are rougher or have more texture will have a higher coefficient of friction.
Is least friction rougher or smoother?
Least friction typically means smoother surfaces. Surfaces with less roughness or texture have lower friction, allowing objects to slide more easily across them.

What are examples of high friction surfaces?
Some examples of relatively high friction surfaces are: sand paper, grass, and asphalt. In general, the rougher the surface, the more friction it has.

How does the roughness of surfaces that are toughing affect the friction between the surfaces?
The rougher a surface is, the higher the coefficient of static and kinetic friction will be.
Does surface type affect the force of friction?
Surface types can affect the force of friction because as the surface gets rough and rougher it has more friction and smooth surface has less friction. if we compare the affect of friction force on a ice and road. Road is much more rough than the ice chunk and if we slide a ice hockey puck on each of the surfaces, we get that smoother surfaces has less friction.
What causes more friction?
Rough surfaces or heavier objects typically cause more friction because there is more contact area between the surfaces, creating greater resistance to motion. Additionally, increased pressure between the surfaces can also lead to more friction.
What are the two factors that effect friction?
The factors that affect friction are the types of surfaces in contact and the normal force pressing the surfaces together. Friction increases with rougher surfaces and higher normal forces.
How will you increase friction?
You can increase friction by using rougher surfaces or materials with a higher coefficient of friction, applying more force between the surfaces in contact, or introducing additional features like bumps or ridges. These manipulations will create more resistance between the surfaces and increase the frictional force between them.
Will friction resist in motion with rough surfaces?
Yes, friction will resist motion more on rough surfaces compared to smooth surfaces because the roughness creates more contact points between the surfaces, increasing the frictional force needed to overcome the resistance.
