The highest was sandpaper which had a average coefficient of friction of 1 666.
Why does carpet have more friction.
Our experiment was testing the theory that if the surface that the weight is sliding across is rough then it will have a higher coefficient of friction.
The frictional forces act in the opposite direction to movement making it harder to move therefore making the car slower and pick up less speed moving down the ramp so travelling less distance.
Typically rough surfaces like brushed concrete or carpet have a higher cof than smooth surfaces like polished marble tile or wood.
During periods of low humidity conditions static electricity can be generated walking across a carpet or other floor covering surface.
This is because there is more friction between the car and carpet than between the car and smooth surface.
Why does carpet have so much friction answers a carpet has so much friction because it has a coarse surface causing the surface to rub against it and cause friction.
Because you are black.
Because there is less.
From our experiments we have concluded that the rougher surfaces have a higher coefficient of friction.
Slips and falls happen when the coefficient of friction cof between the two surfaces is insufficient.

While the consumer will find this irritating it does not mean that the floor covering is defective.
How is friction helpful.
Why does a carpet have more friction than linoleum flooring.
