The amount of work done to get either object moving or keep them moving. Mass of either object to eventually bring them to a stop.
My textbook says speed between two surfaces does not affect friction.
the smoothness othe surface the object is acting on, and direction its going in

Yes. Double the weight and double the friction.

the rougher the surface is, the more friction there will be
normal force acting between them and surface roughness or frictional value that is mieu.
The frictional force is described by F = μR where μ is the coefficient of friction (the roughness of the surface) and R is the force the object exerts perpendicular to the surface.

Things that affect braking distance consist of the following factors: * speed at which you're travelling * weight of the car * road conditions * braking efficiency * friction between the road surface and your tires Things that affect braking distance consist of the following factors: * speed at which you're travelling * weight of the car * road conditions * braking efficiency * friction between the road surface and your tires
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.
