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 spee...

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 ...

How would the rain or a wet road surface affect your stopping distance?

In poor weather conditions, a car's total stopping distance is likely to be longer for a number of reasons.But slippery roads caused by rain, snow or ice will also extend the braking distance.Research suggests braking distances can be doubled in wet conditions – and multiplied by 10 on snow or ice.
