Does oil work better then water in reducing friction between two surfaces?

Oil fills in the gaps (bumps on every surface at microscopic level) of machine parts to reduce friction, damage and heat. If there weren't any oil, the engine would only last minutes before it would melt down. The oil reduces friction but doesn't get rid of it completely....If this answer isn't very good, I'm sorry im just 12:)

Oil provides lubrication.
It is a lubricant and helps things slide past each other rather than rubbing against each other and cause friction.
it fills the space between the two surfaces and makes a small film between the two and reduces friction.
cuz its slippery making it easier for the particles to rub against eachother

∙ 15y agoYep- it a proven fact. Oil is used to reduce friction . Water is used to cool the heat of friction. To add to that oil acts as a lubricant reducing friction. Water actually increases friction because of its surface tension. Water is sticky, for example when you go to the beach that is why sand sticks to your feet only when they are wet, not when they are dry.

You can use a flow of air between two objects to reduce friction (Air hockey), a layer of water or oil, or a solid such as graphite powder. There are hundreds of materials that can be used, and although the most obvious would be oil, it is not neccessarily the best or most efficient. That would depend on what the objects under friction are made from.

∙ 11y agoFunctionally, friction in oil comes from the resistance of the molecules to being displaced from their position and trying to flow past each other.
Quantitatively, you have to specify the temperature, composition, flow rates, and other factors in order to come up with a number to represent "friction". You would also have to specify exactly what you meant by friction - shear stress, shear strain, and viscosity are all ways to describe "friction" and are related, but they are not all the same thing.

∙ 12y agoOil is a lubricant, thus meaning it decreases friction when applied to objects because of its ability to lubricate ( to make slippery or smooth) objects such as gears in a car engine.

How can you reduce friction on surfaces?
Basically all you need to do is make the surfaces smoother. Depending on the material, this can be accomplished by sanding, painting, etc. Adding a lubricant such as oil, grease, water, etc. will also reduce the friction between two surfaces. Another thing that can be changed is the kind of friction. For example, rolling friction is generally less than sliding friction. Fluid friction is lesser still than rolling friction. Applications where friction is decreased for better working stuff are things such as: rollerblades, skate boards, air hockey tables, snow boards, and surf boards.
Does coefficient of kinetic friction depend on weight?
Yes, It does not vary with lesser relative velocity between surfaces.But when the speed exceeds 10m/s ,due to heat produced between the surfaces the co-efficient increases.
How does friction keep our feet from slipping?
Friction plays a crucial role in preventing slipping, and it operates at the interface between surfaces in contact. In the case of walking or standing, the interaction between the soles of our shoes or feet and the ground relies on friction to provide stability. Here's how friction helps keep our feet from slipping: Surface Interaction: Friction is a force that opposes the relative motion or tendency of such motion of two surfaces in contact. When we stand or walk, the soles of our shoes or feet are in contact with the ground or floor. The frictional force at this interface resists any attempt to slide or slip. Microscopic Surface Irregularities: Even seemingly smooth surfaces have microscopic irregularities. Friction occurs due to the interaction of these irregularities at the molecular level. When pressure is applied, the irregularities lock together, creating a resistance to sliding. Normal Force: Frictional force is directly proportional to the normal force, which is the force exerted perpendicular to the surfaces in contact. In the case of standing, the normal force is the weight of the person pressing down on the surface. For walking, the normal force varies as the foot makes contact and pushes off. Coefficient of Friction: The coefficient of friction is a measure of the frictional force between two materials. It depends on the nature of the materials in contact. A higher coefficient of friction means a stronger frictional force and better resistance to slipping. Traction: Traction is a term used to describe the grip or adhesion between the shoe or foot and the ground. The greater the friction, the better the traction. This is particularly important for activities like walking, running, or participating in sports where maintaining grip is essential. Shoe Design: The design of shoe soles also plays a role in enhancing friction. Tread patterns, the choice of materials, and the presence of features like grooves or studs can all affect the interaction between the shoe and the ground. While friction is essential for preventing slipping, it's worth noting that certain factors can influence it. For example, walking on slippery surfaces, wearing shoes with worn-out soles, or walking on surfaces with low friction coefficients (such as ice) can reduce the effectiveness of friction, making slipping more likely. Additionally, substances like water, oil, or ice can significantly impact the coefficient of friction and increase the risk of slipping.
What are the two main causes of friction?
Static friction, which is the friction that needs to be overcome to get an object moving ( different values on different surfaces ), and kinetic friction, which is the friction imparted to the object as it mover along ( different values for different surfaces ).
Define sliding friction and rolling friction?
sliding friction is less than static friction. it is also very easy to move better than static friction.
What Has the greatest amount of friction between solid surfaces?
Solids that are actually glued, or better yet soldered, together.

How does an object move on a rough and on a smooth surface?
It is on smooth surfaces because the amount of friction is less.

Yes, It does not vary with lesser relative velocity between surfaces.But when the speed exceeds 10m/s ,due to heat produced between the surfaces the co-efficient increases.
How and where is friction used in a bicycle?
Friction occurs in any relative motion. The rougher the surfaces in contact, the higher the friction between them. In a bicycle, friction is what makes it move when you pedal. There is friction between your foot/footwear and the pedal. That is why a bicycle pedal is rarely a smooth surface. Your foot shouldn't slip off it. The handlebars are also rough so that the friction prevent your hands from slipping off while riding. The seat is made of rubber or a similar material usually as it is rougher and softer than a metal or wood, reducing sliding on the seat. Friction between the tires and the ground is what makes the bicycle move. That is the reason why a worn out tire is more likely to skid on the ground, and also the reason why mountain bikes and bikes built for rougher terrain have deeper and better designed grooves on their wheels to create more friction and thus more traction.
Would bigger or smaller roller be better for reducing frction?
Smaller both in surface area and mass would reduce the friction
How does friction influence?
Friction is caused when objects or substances bump into each other. When you swim you create friction between you and the water which is called Fluid friction. Better yet look it up

How does a car create heat?
Friction is the primary cause of heat in cars. Friction exists between two surfaces (such as pistons and cylinder walls) that slide across each other and creates heat. This heat must then be countered by a cooling process, which circulates cool water/coolant through the engine block and then returns the now hot water to a radiator. The heat spreads throughout the very large surface area of the radiator and is then cooled by air passing through the radiator. The water has now been cooled and repeats this cycle again and again. Oils and lubricants also aid in reducing operating temperatures by reducing the friction between surfaces, and sense lower operating temperatures mean greater efficiency (less energy is lost through heat transfer so more mechanical energy is produced), better lubricants such as synthetics are used. A recent development designed to reduce heat within cylinders is the process of lining cylinder walls with ceramics, which reduce friction and cool exponentially faster than metal alone. Ceramics have also been applied to exhaust systems and brakes in order to reduce the effects of heat.
