Friction force has NO "surface area" component. This is hard to understand (and it sounds like the teacher who asked this question doesn't quite understand either...). Imagine this-- A block of wood with a flat bottom and a legged wooded stool sit on a smooth inclined plane. Do we have to know the contact area (surface area) of the block or the stool legs to determine the angle at which each will slide? No. We merely need to know the applied weight and the coefficient of friction between the materials. So why does a dragster have such big smooth tires? Wouldn't thin knobby bicycle tires do as well? As far as the friction force is concerned, Yes. But the issue the dragster faces is how to transfer the engine power to the asphalt to accelerate the car. This involves HUGE problems of material strength, power, heat and wear that takes the problem far outside the narrow concerns of friction force.

Do handlebars increase friction?
Handlebars do not directly increase friction. Friction is mainly dependent on the surface materials and the force applied. However, if using handlebars allows a person to have a better grip on a surface, it could indirectly affect friction by improving control and preventing slipping.
What are the two main factors on which friction depends?
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 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.
Does an objects weight affect the amount of friction between the object and the surface?
No, an object's weight does not directly affect the amount of friction between the object and the surface. Friction is determined by the nature of the surfaces in contact and the normal force acting between them, which is influenced by weight but is not directly proportional to it.
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.
Is it true that weight affects the amount of friction between the object and a surface?
No, weight does not directly affect the amount of friction between an object and a surface. The factors that affect friction are the nature of the surfaces in contact and the force pushing them together. The normal force, which is perpendicular to the surface, is what influences the frictional force, not the weight of the object.
What happened to the coefficients of friction as the surface area of the contact increases?
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.
What is Friction on horizontal surface?
Friction on a horizontal surface is the force that resists the motion of an object sliding or moving along that surface. It arises due to the contact between the surfaces of the object and the surface it is sliding on. The amount of friction depends on factors such as the nature of the surfaces and the normal force pressing them together.
How do different weights affect friction?
Friction is a resistance force imparted on an object sliding across a surface where the force is directly proportional to the WEIGHT of the object. The heavier the object that is moving across the surface the higher the frictional forces.
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
How much friction is produced by brakes to stop a vehicle running at 80kmhr?
friction acting btw the road surface and wheel depends upon the braking retardation of the vehicle. every surface has its own friction coefficient which represents the maximum value , however friction can act in range from 0 to that max value , and this value depends upon the braking retardation.
Can a prism slide?
Yes, a prism can slide along a surface because it has flat sides that can make contact with the surface. The movement may be influenced by factors such as the friction between the prism and the surface, as well as the angle at which it is placed on the surface.
