Which has less friction a dry road or wet road?
a wet road also see hydroplaning
Why is braking less effective on a wet road than on a dry road?
Two reasons. The wet road has a lower coefficient of friction that the dry one. It is more slippery. The same goes for the brakes. If they are wet, they will be less effective because of the same reason. A higher amount of friction wastes more energy, in this case momentum, causing a loss of speed. http://en.wikipedia.org/wiki/Friction
Coefficient of friction of road and tire?
Coefficient of friction on raod and a tire varies depending on the condition of the road and tyre Wet Road: 0.4 Dry Road: 0.7 This is the average coeffecient for these conditions again it can vary
Why is it to stop a car on a wet road?
it is harder because there is less friction with lubrication -which is what water is -and you need friction for the breaks to work

Why is breaking more difficult on wet roads than dry?
it is more difficult to use brake as wet roads do not have friction
When the road is wet it takes times longer to stop?
Yes. There is less frictional force between the car tyres and a wet road surface than with a dry road surface.
What will happen to friction if the road is wet?
The friction will go down drastically.
What force causes a bisycle to take longer to stop on a wet surface than a dry one?
Friction. There is less friction between your bike tire and the ground when it's wet, increasing the stop time.
If a water slide was dry how would the friction be different?
Water can absorb friction because it's wet and slippery. When things are dry, there nothing slippery or wet to absorb the friction, so the friction becomes stronger.
Why are stopping distances for breaking cars increased on wet roads?
The wet road surface has less friction as the water interacts with the rubber and acts somewhat like a lubricant
Why do cars slip on wet road?
the tires are made of rubber. when rubber gets wet, it gets slippery, which means less friction from the tires to the ground, making it easy for the car to keep going instead of stopping. also, a car is very heavy, so momentum definitely kicks in ALOT. think of it this way. car tires that are dry + dry land = alot of friction and quick stopping. but make every thing slippery and the friction goes away.
