answer it yourself ;)
The roughness of the two objects coming in contact determines the degree of friction.
Friction and Gravity are the two forces that affects an object's velocity. Friction is caused by both air and the surface on which an object is moving. Gravity is caused by Earth.
Weight and surface affect friction. The more mass an object has more friction that will occur ex:/ It would be harder to slide an elephant across a floor than a hockey puck. This is because the large amount of friction on the elephant would slow it down. The smoother the surface the less friction. ex:/ There will be more friction on a floor of sandpaper than there would be on a floor of ice.

What type of friction is air resistance?fluid friction. Air resistance is fluid friction. Air resistance occurs between the surface of a falling object and the air that surrounds it. Rolling friction occurs when a rounded surface moves over a solid and sliding friction occurs when a solid moves over another solid. Static friction occurs when a solid touches another solid but there is no movement.What two factors affect air resistance?size and shape. Size and shape are the two factors that affect air resistance. Air resistance works with surface area, so the more surface area, the more air resistance. Think about when you drop two pieces of paper: one crumpled and one flat. The crumpled one falls faster because there is less air resistance acting on the paper.
the rougher the surface is, the more friction there will be
The two variables that affect friction are the surface roughness of the materials in contact and the force pressing the surfaces together. As the roughness increases or the force increases, friction typically increases as well.
The rougher a surface is, the higher the coefficient of static and kinetic friction will be.
Surface temperature, Weight of the object, Roughness of surface and the object
The friction graph shows that as surface roughness increases, the force required to overcome friction also increases. This indicates that there is a positive relationship between surface roughness and the force needed to overcome friction.
The variables that affect friction include the types of surfaces in contact, the force pressing the surfaces together, the roughness of the surfaces, and the presence of any lubricants or contaminants.
Depending on the roughness or smoothness of the surface, it will increase friction if it is rough,(which has more microscopic hills and valleys). If the surface is made of a smooth material, it will decrease friction
The variable that does not affect friction is the surface area in contact. Friction is primarily influenced by the nature of the surfaces in contact, the applied force, and the roughness of the surfaces. The surface area does not have a direct effect on the frictional force generated between two surfaces.
Friction depends on the nature of the surfaces in contact and the normal force pressing the surfaces together. The roughness of the surfaces and the force pushing them together directly affect the amount of friction between them.
The frictional force is described by F = μR where μ is the coefficient of friction (the roughness of the surface) and R is the force the object exerts perpendicular to the surface.
Depending on the roughness or smoothness of the surface, it will increase friction if it is rough,(which has more microscopic hills and valleys). If the surface is made of a smooth material, it will decrease friction
The factors that can affect the amount of friction acting on an object on a solid surface include the roughness of the surface, the weight or normal force pressing the object onto the surface, and the types of materials in contact. Additionally, the presence of lubricants or contaminants can also influence friction.
