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.

this is because there is less friction on the smooth road than on the rough, ( friction is the force that opposes movement) hope this helps
When we roll a barrel on the road, rolling friction acts in the direction opposite to the direction of rolling. In case of pulling, kinetic friction acts opposite to the direction in which the barrel moves. The coefficient of rolling friction is almost always less than the coefficient of kinetic friction. So therefore, in layman's terms, rolling friction is less than kinetic friction, therefore less resistance is faced by the barrel while rolling.
When you go uphill, gravity helps slow down the car.
A steel needle will float in water as a consequence of surface tension. A boat floats in water because it displaces sufficient air to make its effective density less than that of water. Usually though, solid, spherical objects, for example, will float if they are made of materials that are less dense that water, which is to say that they have less mass per unit volume than water. In ordinary, imprecise language we say things weigh less than water.
I will assume that you are asking if it will float in water. That depends on the shape of the object and it's density, or you could say it depends on the effective density of the object where that takes into account any voids inside the object. If the material the object is made of is less dense than water, then the object will float. If the material the object is made of is denser than water and there are no internal voids, then it won't float. If the material the object is made of is denser than water but the object has sufficient internal voids so that its effective density is less than that of water, then it will float.
No, the patch is less effective than the shot.
There is less drag at altitude than at sea level. The air is thinner at altitude.
it intial power is low and did not produce much energy
that is a false question. less rubber on the road means less friction and this calls for better fuel economy maybe, efficient means high-performance, with a good grip and braking characteristics. Wider tires also mean better handling.
nothing less than effective
247,780 road casualties which is 4% less than what it was in the year 2006.
Less resistance on a smooth concrete road.
Because the rough road has more friction, thus expending the balls energy quicker than smooth road with less friction.
yes of course
Yes, Of Course........Bold Riding Quality ...Good road view from the driver seat, Good diesel engine............Spacious than Bolero & Scorpio........ Disadvantages: Braking is average....... So there must be an eye on braking while driing sumos .. that's it...
Braking distance is usually measured by how fast you can stop at 60mph, 60-0, the make of a car is the factor of the stopping distance, each car varies. Your car can have disc brakes or drum brakes or both. Disc brakes are more effective than drum brakes. But braking distance is usually showed by how many feet it takes to stop from 60mph
Less, but they are effective for screening.
