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 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.
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.
What object would experience the most fluid friction?
An object with a large surface area and irregular shape would experience the most fluid friction. This is because more surface area comes into contact with the fluid, creating more opportunities for friction to occur due to the irregularities in the object's shape.
Why do large particles in a rock layer cause less friction than small particles?
Large particles have less total surface area, so caused less friction then the smaller particles do

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.
Why kinetic friction is less than sliding friction?
there is more surface area contact with kinetic friction as opposed to sliding friction

How does a tire increase friction?
A tire increases friction by providing a large contact area with the road surface, which allows for more interaction between the tire and the road. The tread pattern on the tire also helps to grip the road surface, especially in wet or slippery conditions, further increasing friction.
Is there more friction in a thick or a thin wire?
A thicker wire typically experiences more friction due to its larger surface area in contact with other surfaces. This increased surface area increases the resistance to motion, resulting in higher friction compared to a thinner wire with less surface area.
Is friction affected by the amount of surface that is touching?
No: this is a common misconception Friction= Normal force* Coefficient of friction where Normal force= Mass* Acceleration due to gravity* Cos(angle of surface) and the coefficient of friction is an intrinsic property of the surface Therefore, only the mass of the object and the surface composition affect friction
