The magnitude of the force of friction is a function of the normal (perpendicular) force of the object and the surface properties of the two materials. It's a linear relationship; for example, if an object is sliding along a horizontal table with a weight of 2 lbs, then friction will double if an additional 2 lbs of force is added to the object.
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 force to resist static sliding is independent of the surface area. The roughness of the two contact surfaces is generally provided as a unitless coefficient or a friction angle. The force that resists sliding is this coefficient of friction (c) x Normal force.
Surface does NOT affect force of friction. Ff = N*u u being coefficient of friction and N being normal force. No wheres in the equation is surface area is used thus force of friction is NOT affected by surface area.
friction occurs because surfaces are not perfectly smooth , even ice , which looks perfectly smooth , actually has a bumpy , uneven surface.
The more uneven the surface, the more friction there is.
friction
There is really nothing unusual here, but some people may be surprised when they first find out that the amount of friction between two surfaces doesn't depend on the surface area.
Because the size is a kintec force on it
Yes. Weight, being a force perpendicular to the surface, affects the magnitude of the friction, but not the friction coefficient.
Yes. Double the weight and double the friction.
Rough surfaces, the rougher the surface, the greater the friction.
The more uneven the surface, the more friction there is.

No, it doesn't, the only important thing is the force perpendicular to the surface (weight) and friction coefficient.
Rough surfaces, the rougher the surface, the greater the friction.
Yes. Double the weight and double the friction.
The larger the contact surface, the more friction. The more uneven the surface, the more friction. The material of the surface has also an effect on friction.
The coefficiant of friction between the two surfaces and the normal reaction force of the object lying on the surface
the difference between this is that surface area
The normal force between them.
No. The speed of the object does not affect the amount of friction between an object and the surface. Friction is affected by the types of surfaces in contact, smoother surfaces produce less friction, and the weight of the object moving horizontally affects the resistance relative to the two surfaces in contact. Greater weight causes greater resistance.
