Yes. Double the weight and double the friction.
more rough surface more friction object have
The coefficiant of friction between the two surfaces and the normal reaction force of the object lying on the surface
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.
Water can make a flat surface more slippery, which will decrease the amount of friction
the rougher the surface is, the more friction there will be
friction
No, it doesn't, the only important thing is the force perpendicular to the surface (weight) and friction coefficient.
Yes. Double the weight and double the friction.
the smoother a surface is, the less friction it produces.
The rougher a surface is, the higher the coefficient of static and kinetic friction will be.
more rough surface more friction object have
The wind at the surface of the ground where the molecules are having friction is moving slower than the wind above the surface.

answer it yourself ;)
surface friction and sliding friction
