I'm no expert, but from just my observations, it seems that it depends on what is happening between the surfaces that are either wet or dry. example: a sandboard which people skim on the sand with a thin layer of water between the board and the sand offers little resistance and allows the rider to skim over the sand smoothly. without the water, this would be impossible as the board would dig into the sand and the rider tossed off. the same with a 'slip and slide', that toy kids wet down and slide on a sheet of plastic. that also uses water as a thin layer of lubricant. however, if the water depth were increased, the person would not slide as fast, as in the end of a water slide they increase the depth of the water to slow the rider down.
but for a different approach to this, i now bring up a motorcycle. it has tires rotating on a dry asphalt surface which also rotate on bearings between the wheel and the axle. on a slight grade, it will roll well as the friction acting upon the bike and rider is mainly the tire's friction upon the dry asphalt, the wind that both bike and rider are passing through, and the mechanical friction of the bearings in the wheels, the chain on the sprockets (and let's just say that the bike is in neutral), each individual link in the chain, and the friction of the bearings supporting the front countershaft sprocket. but just for this experiment, let's say that the chain was removed from the motorcycle so it can roll as freely as possible without any friction from drivetrain. if the road is dry, it will roll a certain distance at a certain speed. there is also the humidity in the atmosphere which for the sake of this experiment we will leave constant. if the road has a very slight coating of water on it where it is wet but not to the point where drops are adhering to the tire and being flung off, the bike rolls slightly faster and farther. add a little more water to the road and now the tire is very wet, water is being flung off the tires and the bike does not roll as fast or as far. add a lot of water and the bike's speed is noticeably slower. i think that surface tension on a larger volume of water helps create more friction than a minute amount of water.
i'd also think that an airplane that is flying with a thin coating of water on its surfaces would have more aerodynamic drag due to weight, altering the shape of the smooth surfaces which creates non-uniform and chaotic air turbulence behind the moving object.
this is a tricky question and the answer (which i am not sure i even have provided anything useful to you) is that it depends on the thickness of the water. my examples tried to cover both an object in motion, one without bearings, and one with bearings.
i am no expert, barely graduated high school, but i saw that this had no answer and want to help what i can. i know there's a lot of college and professional people out there that are going to blast this right out of the air, but that is good for it will prompt them to write a more accurate and helpful article, which the person asking the question wanted in the first place.
my best to you all.
What else can I help you with?
How does water affects surface friction?
Water can decrease surface friction by creating a slippery layer between two surfaces. When water is present, it can reduce the grip or traction between surfaces, leading to lower friction. This is why wet surfaces can be more slippery compared to dry surfaces.
What types of weather cause friction on surfaces to increase?
Wet or icy conditions can cause surfaces to become more slippery, increasing friction between objects. Additionally, strong winds or storm conditions can generate forces that increase the friction on surfaces.
Why do smooth and wet surfaces have the least friction?
This is because the surface is more even and equal. For example if you have a wooden surface and a glass surface, the wooden surface would have more friction than the glass, because it is more un-even than the glass surface
What surface has the least amount of friction?
The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.
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.

What is wet sandpaper and how does it differ from dry sandpaper in terms of its application and effectiveness?
Wet sandpaper is sandpaper that is designed to be used with water or a lubricant to reduce friction and prevent clogging. It is typically used for wet sanding, which is a technique used for smoothing surfaces and finishing materials. Wet sandpaper is more effective for achieving a smooth finish on surfaces that are prone to overheating or clogging when dry sanding. Dry sandpaper, on the other hand, is used without any additional lubrication and is better suited for rougher surfaces or materials that do not require a fine finish.
How effective is wet sand paper in smoothing surfaces compared to dry sand paper?
Wet sandpaper is generally more effective than dry sandpaper in smoothing surfaces because the water helps to lubricate and cool the abrasive material, reducing friction and preventing clogging. This allows for a smoother finish and can also extend the lifespan of the sandpaper.
What types of weather cause friction on surfaces to increase?
Wet or icy conditions can cause surfaces to become more slippery, increasing friction between objects. Additionally, strong winds or storm conditions can generate forces that increase the friction on surfaces.
Why does a racing car with 'wet' tires travel more slowly in dry weather than one with 'dry' tires?
Because the 'wet' tyre and dry ground has no friction, but 'dry' tyre and dry ground is more likely to be faster
Where most like live the fungi to wet or dry surface?
Wet surfaces.
Why do the brakes on abike work better on a dry day than on a wet one?
Brakes on a bike work better on a dry day because dry surfaces provide more friction between the brake pads and the rims or rotors. In wet conditions, water creates a lubricant layer, reducing this friction and making it harder for the brakes to grip effectively. Additionally, moisture can cause brake components to rust or wear more quickly, further diminishing braking performance. Overall, the combination of reduced friction and potential corrosion leads to less effective braking on wet days.
Which has less friction a dry road or a wet road?
A wet road has less friction since the water acts as a lubricant.
What are the differences between wet and dry sandpaper in terms of their effectiveness and applications?
Wet sandpaper is more effective for smoothing surfaces and preventing clogging, making it suitable for wet sanding and finishing tasks. Dry sandpaper is better for rougher surfaces and faster material removal, making it ideal for dry sanding and shaping tasks.
Why do smooth and wet surfaces have the least friction?
This is because the surface is more even and equal. For example if you have a wooden surface and a glass surface, the wooden surface would have more friction than the glass, because it is more un-even than the glass surface
What baseball would go farther a wet or dry one?
dry wet would cause a friction in contact and in flight.
Is there wet mold and dry molds?
Mold can grow on surfaces with high moisture content (wet mold) as well as on dry surfaces (dry mold). However, mold requires moisture to grow and thrive. Wet mold is typically more visible and easier to detect due to the presence of moisture, while dry mold may not be as noticeable but can still release spores and cause health issues.
