How does surface area affect friction?
As the surface area increases so does the friction.
Does the surface area of an object affect the amount of friction between the object and the surface?
The force of friction on an object is equal to the coefficient of friction times the force perpendicular to the surface (normal force). When the mass of an object increases, the normal force increases, and the force of friction also increases. However, because the equation does not involve surface area, increasing surface area has no affect on 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.
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
Friction actually depends on the roughness or smoothness of the surfaces of the object. Even some smooth objects that we usually see everyday (ex. glass, mirrorr,etc.) aren't that smooth when magnified by strong microscopes. They still have rough surfaces therefore they can also have friction. Factors that affect friction: 1.) Adhesion 2.) Surface roughness 3.)The area of an object which is in contact with the surface. The larger the surface in contact, the greater friction…
It does not. Friction is the product of coefficient of friction and normal force. The coefficient of friction depends on the materials in contact with each other. The normal force (the force holding them together) increases only the magnitude of friction. If you increase the area, you decrease the force per square inch (pressure) equally.
The type of surface on which the object is sitting affects the coefficient of friction. Mass does not affect the coefficient of friction; it affects the the amount of friction on a given object. The coefficient of friction, µ, is found by dividing the force of friction by the normal force (µ = Ff ÷ FN).
Dry surfaces For low surface pressures the friction is directly proportional to the pressure between the surfaces. As the pressure rises the friction factor rises slightly. At very high pressure the friction factor then quickly increases to seizing For low surface pressures the coefficient of friction is independent of surface area. At low velocities the friction is independent of the relative surface velocity. At higher velocities the coefficent of friction decreases. Well lubricated surfaces The…
