What else can I help you with?
Which has less friction a dry road or a wet road?
A wet road has less friction since the water acts as a lubricant.
Which has less friction a dry road or wet road?
A dry road typically has less friction than a wet road. Water on the road surface can reduce tire grip, leading to an increase in friction and longer stopping distances. The lower friction on wet roads can increase the risk of skidding and losing control of the vehicle.
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

What road conditions will cause friction to reduce?
Wet or icy road conditions can cause friction to reduce because surfaces become slippery, reducing the ability of tires to grip the road. Additionally, oil spills or loose gravel on the road can also decrease friction between the tires and the road surface.
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
How does a tire increase friction?
A tire increases friction by providing a large contact area with the road surface, which allows for more interaction between the tire and the road. The tread pattern on the tire also helps to grip the road surface, especially in wet or slippery conditions, further increasing friction.
Why is breaking more difficult on wet roads than dry?
Breaking on wet roads is more difficult than on dry roads because water reduces the friction between the tires and the road surface. This decrease in friction makes it harder for the tires to grip the road, resulting in longer stopping distances and increased risk of skidding. Additionally, water can mix with oil and other fluids on the road, further reducing traction.
Why is driving on wet roads so difficult?
The amount of friction is reduced. That is one thing that keeps the tires on the road.
How can friction cause an accident?
Friction can cause an accident when it is reduced between the tires and the road surface, leading to less traction and increased chances of skidding. This can happen due to factors like wet or icy roads, worn-out tires, or speeding. The lack of friction can cause the driver to lose control of the vehicle and result in an accident.
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
Some road surfaces are more slippery than others when wet true or false?
yes cement road surfaces are more slippery when wet then asfault yes the worst would be if it is covered by a film of liquid sufficient enough to reduce the coefficient ecstatic friction between the tyre and the road to essentially zero, but not so deep as to introduce a new source of friction
