What is the force that stops a car from sinking into the road surface?

Surface tension, and upthrust. If the object is small and light enough, the force provided by the intermolecular bonding in the liquid will create a surface underneath the object, preventing it from sinking. An example of this is a skitterbug jumping across the surface of a pond. Upthrust is generated by the force of the liquids molecules bumping against the object. Upthrust is proportional to the amount of liquid displaced by the object.

Explain why ears skid on curves when the road is icy?
When a car is on a curve, centrifugal force tends to force it outwards. Normally, this force is resisted by the car's tires gripping the road surface. However, ice on the road reduces the friction and therefore the tires cannot grip so well.
Does surface type affect the force of friction?
Surface types can affect the force of friction because as the surface gets rough and rougher it has more friction and smooth surface has less friction. if we compare the affect of friction force on a ice and road. Road is much more rough than the ice chunk and if we slide a ice hockey puck on each of the surfaces, we get that smoother surfaces has less friction.
Friction between a wheel and a road?
Yes? This isn't much of a question but there IS friction between a wheel and the road. The friction between the tyre rubber and the road surface stops the rubber moving with respect to (wrt) the road when force is applied, allowing the vehicle itself to move. Some of the energy is dissipated as heat. During acceleration the boundary relationship represents 'inertial frame transition', and when in constant motion the wheel and bearings form the boundary between inertial frames.
What are the 3 effects of forces?
When a force acts on an object with mass, it will result in three possible effects:AccelerationDecelerationBalance (no impact)
Describe the size and direction of the frictional forces when a car stops on a flat road?
describe the size and direction of the frictional forces when a car stops on a falt road?
How big is the frictional force when a car stops on a flat road?
Very big because it has no grip on the surface for the frictional force to stop and it takes time to stop the car.
How has advances in crash barriers and road surface technology helped road safety?
The crash barriers have been made stronger which stops the car going through them. The road surface makes more friction on the road.
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.
How does a vehicle stops after applying break with out any external force does it contradicts Newton's 1st law of motion?
The car's tires apply a force against the road, therefore the road applies a force against the car in the opposite direction (Newton's Third Law).
Which of Newton's laws of motion is demonstrated when a car applies its brakes on an icy surface but the car continues to slide along the surface?
Newton's First Law: objects at rest tend to stay at rest, objects in motion tend to stay in motion. When the brakes are applied, the friction with the road surface is the force that stops the car -- on ice, this friction is greatly reduced.
Why roads dry quickly after rain?
The water remains of the surface of the road and thus is able to evaporate quickly when the rain stops and the sun comes out.

I read somewhere that a car going 75 mph only weighs about 5 pounds on a road surface. Is that true?
If a 3,500 lb car only applied 5 lbs of pressure to the road surface then fasten your seat belt and get ready for take off. The faster you go in a car built within the past 15 or so years the greater the pressure on the road surface. It is referred to as down force and the pressure exerted will increase the weight of the car beyond the static weight. Which means you will be placing several thousand lbs of force to the road surface.

Which surface would you slide further on road covered in ice or straw?
A road covered in ice; the frictional force that would slow you down would be much greater on a road covered in straw than one covered in ice.
