Want this question answered?
By making the surface rough for increasing friction....... use any lubricating material to reduce the friction.. use rollers to decrease the friction force.. make less contact between 2 connecting materials..
well the tirezss material
You can change friction by the material. e.g ice, low friction. carpet high friction.Or you could add a lubricant :D
kinetic friction
With what material? Coefficient of friction is for two materials.

Wood, or any other material, could be used to introduce static friction to a system. The choice of material(s) depends on how much static friction the system requires. Each material has its unique coefficient of friction.

Friction boards are made of 4 different surface materials: cork, rubber, sandpaper, and Masonite. These boards are used to study friction between different types of material or matter. A device to measure friction.
yes. there is friction to resist every movement we make
kinetic friction
Friction doesnt not depend on the surface area...but the force of friction does! We cannot change the friction of a material but we can change the force due to that friction on another material in contact with it. Using this concept, racing cars have bigger tires to minimise the force of friction acting on them. They cannot change the friction of the road, so they change the resultant force on the tires.

Use Cd's as wheels to make less friction
I would say a carpet or rope has alot of friction. but if you want to test for your self use a toy car on a slope and let in roll down the longer it takes to get to the end the more friction the material has.
