No. Friction depends on the normal force and a constant know as the coefficient of friction. The area of contact is completely irrelevant. The material in contact is what sets the coefficient and the force exerted between the two is what is represented by the normal force.

No. It makes since if you think about it. Frictional force is directly related to the normal force, so the more weight the more friction. If you increase the area of contact between two objects without changing the the force, then while there is more to be in friction with, there is force per square unit of space (called pressure) and therefore less friction per unit of space. Therefore, since the force spreads out, the frictional force stays the same.

Frictional force is independent of the area of the surfaces of contact.

yes cuz there is astatic friction force and kinetic friction force but remember u have to know if that surface is rough or roughless surface.and notice the friction force inrease by increasing the area.
