What does converting sliding friction to rolling friction do to a system?

One way to show this would be to do the following experiment:
Take a coil spring and tie two pieces of string to each end of it. Then tie one of the strings to something with wheels... preferably something whose wheels have a locking mechanism (maybe an office chair, a wagon, a bike). Pull the wheeled object by the string along a flat, level surface at a constant speed and note the elongation of the spring. Now try locking the wheels and pulling the object again in the same manner ... as long as circumstances are "normal" (i.e., you're not doing this on a skating rink or a floor covered in oil or something), it should feel harder to pull the object with the wheels locked, and the spring should elongate more as you pull it.
If fact that the spring is elongating more when sliding demonstrates that there is a higher force of tension in the string pulling on it. The higher tension is caused by greater drag in the chair, which is in turn caused by sliding friction. Voila!

Could you use wood for static friction?
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.
Did the benefits of converting to metric system outweigh the cost?
Yes, if it didn't no country would convert.
If 250 watts of power is input into a mechanical system can you get 250 watts of power out?
Yeah all you need is a completely friction less system.
What advantages does the metric system have over systems that were used previously?
The metric system uses simpler math when converting measurements and will allow us to use recipes from all over the world.
Why does the decimal moves when you are converting in the metric system?
Because conversion in the decimal system is based on multiplication (or division) by powers of ten. Each multiplication by ten is equivalent to moving the decimal point one place to the right.
What are two examples of friction?
Say you are driving a car or riding a motorcycle and you just remove you foot or hand from the accelerator. What will happen? After some time depending on your velocity, the vehicle will stop. Why? Consider your entire vehicle an ideal system meaning that no part provides any sort of friction. Now consider road, road is rough and will definitely provide friction. Since your vehicle's tires are rolling against the road, the road will provide friction in the direction opposite to that of your vehicle's motion. In real situations, both tire and road will contribute to the rolling friction.
What features of a car reduce sliding friction?
Antilock Brake System (ABS) & tread on the tires.
Why do rough surfaces slow down sliding more than smooth surfaces?
rough surfaces take more energy from the system in the form of friction
Formulae for converting kg into meters?
Kilograms are a unit of weight in the Metric System. Meters are units of distance in the Metric System. There can no more be a formula for converting kilograms to meters then there could be converting pounds into yards.
Where can friction be usful?
In a braking system
How does friction affect effect the efficiency of a system?
depends on what system your talking about.
How does braking system in automobiles work?
Friction
What are the types of joints in skeletal system?
sliding, hinge and balla and socket
Could you use wood for static friction?
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.
What is meant by transition economies?
The economies which are converting from social market system to capital market system
Why does friction reduce the efficiency of machines?
Friction requires energy to overcome it. This causes loss of energy in the system. Loss of energy in a system, by definition, is a reduction of efficiency.
What is direct implementation?
Direct Implementation is the process of converting to a new system by removing the previous system altogether.
