How does surface area affect friction?
Surface area does not directly affect friction; rather, friction is related to the roughness of the surfaces in contact. An increase in surface area may lead to an increase in friction if there are more contact points between the surfaces. However, the type and condition of the surfaces, as well as the force pressing them together, also play a significant role in determining friction.
Does surface area affect static friction?
Yes, surface area can affect static friction. Generally, larger surface area will result in greater static friction because there is a larger area for interlocking between the surfaces, increasing the resistance to sliding.
What fricton occurs when a object rolls over a surface?
The friction that occurs when an object rolls over a surface is called rolling friction. It is generally lower than static or kinetic friction because the object's motion is distributed over a larger area during rolling. Rolling friction is dependent on factors such as the nature of the surfaces in contact and the weight of the object.
What happened to the coefficients of friction as the surface area of the contact increased?
As the coefficient of friction is not function of the area or not related to the area of the contact surface so the coefficient of friction remains constant on the increase of the contact area. The coefficient of friction depends upon the material of the friction surfaces only.
How does friction force between two surface depends on based on area of contact?
Friction force between two surfaces is not directly dependent on the area of contact. It is primarily influenced by the types of materials involved, their roughness, and the force pressing the surfaces together. However, in some cases, a larger area of contact may distribute the force more evenly and potentially reduce the overall friction.
If friction isn't dependent on surface area but only on the coefficient of friction between two surfaces and the reaction force then why do racing cars use bigger tires with greater area?
Friction doesnt not depend on the surface area...but the force of friction does! We cannot change the friction of a material but we can change the force due to that friction on another material in contact with it. Using this concept, racing cars have bigger tires to minimise the force of friction acting on them. They cannot change the friction of the road, so they change the resultant force on the tires.

How will different masses affect friction?
friction depends on type of surface and force applied its not dependent on the mass till gravitation is taken into account

When an object over a surface the kind of friction that occurs is called friction?
false
Does fluid friction vary with speed and area contact?
Fluid friction will vary with speed and the area of contact when referring to air friction or drag. When referring to surface friction then only the area of contact will vary.
Does surface area have an effect on friction?
Yes, surface area can have an effect on friction. In general, larger surface areas in contact can increase friction due to the increased contact between surfaces. However, other factors such as the material properties of the surfaces and the force pressing them together also play a role in determining the overall friction force.
Why kinetic friction is less than sliding friction?
there is more surface area contact with kinetic friction as opposed to sliding friction
