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.
Yes. Weight, being a force perpendicular to the surface, affects the magnitude of the friction, but not the friction coefficient.
friction affects in any Circumtances
The purpose of lubrication is to reduce friction. Microscopically two surfaces in contact look like huge mountains trying to slide over each other, a very tough task. A lubricant fills in the gaps, and in effect smooths the surfaces. Similarly, a lubricant on a microscopic level is like liquid ball bearings that facilitate the surfaces 'rolling' over one another, further reducing friction. Many factors go into making a lubricant "Good". Its resistance to heat and pressure, its viscosity, corrosive affects, etc.
The factors affecting sliding friction include the "roughness" of the surfaces in contact. That includes both of the object being slid and the surface on which it is sliding. The mass of the object being slid is also a factor. To some extent, any changes in either contact surface as the sliding motion occurs will affect sliding friction. There is generally a coefficient of friction that takes all of these factors into account, both in the static range and in the kinetic range of friction.

Hi. There is no friction in archery because there is no warmth like rubbing you hands together. FORCE=muXN
Friction is resistance to motion along the concerned surfaces.The more the surfaces are uneven that is, they are having bumps and depressions, the more is their tendency to resist the motion.And hence more is the frictional force and vice verse.
Friction and Gravity are the two forces that affects an object's velocity. Friction is caused by both air and the surface on which an object is moving. Gravity is caused by Earth.
Yes. Weight, being a force perpendicular to the surface, affects the magnitude of the friction, but not the friction coefficient.
By using kinetic friction
friction affects in any Circumtances
Speed is how fast something is moving. When to things are traveling at the same speed and rubbing together, they can cause friction.

no, friction just changes the motion of an object.
Yes, linearly. The more it weighs, the more friction.
