when we polish surfaces, the molecules or atoms of surface come closer to each other so there is no space for fiction so it is reduced but not reduced to zero
we cant reduce friction to zero
When we polish a rough surface smoothly,the unequalities gets reduced,therefore friction is reduced
What else can I help you with?
How is friction between the moving parts of a car engine reduced?
Friction between the parts of an engine is reduced by applying oil between its parts. mobiloil is particularly used for this purpose.
Describe three different ways to decrease the force of friction between two surfaces that are moving past each other?
Three ways to decrease the force of friction are- 1.)Polishing 2.)Lubrication 3.)Ball Bearings
Why is it easy to slip on a floor that is wet?
The puddle changes the coefficient of friction of the floor. Therefore it becomes more slippery.There are ways to control or change the COF of a floor surface with specialized floor treatments which will make the area much more safe and prevent slip and falls.
Which part of a bicycle are designed to decrease friction?
Any bicycle part that makes contact with another part but needs to move to function must have friction reduced. The wheels bearings, steering head, pedal bearings in both the hub and pedal, and the chain links all are designed for minimum friction but they also need lubricant.
why it is important to reduce friction at movable joint?
friction will resist smooth motion at a moveable joint so reducing friction allows joint to move freely
What types of surfaces will produce the least amount of friction?
Surfaces that are smooth and lubricated will typically produce the least amount of friction. Examples include ice, polished metal, and Teflon-coated surfaces. Friction can also be reduced by decreasing the weight pressing the surfaces together.
What types of surfaces create the most friction?
Rough surfaces with irregularities and high coefficients of friction, such as sandpaper or concrete, create the most friction due to increased contact points and resistance to sliding. Smooth surfaces, like ice or polished metal, generally have lower friction due to reduced contact area and smoother interactions between surfaces.
How can friction be reduced or if its helpful what can be done increase the friction?
Friction can be reduced by using lubricants like oil or grease on surfaces. To increase friction, surfaces can be roughened or materials with higher coefficients of friction can be used. Adjusting the weight or pressure between the surfaces can also increase friction.
What happen to the force of friction if the surface of contact is polished?
Friction is still there and gravity causes that, if there is no gravity there is no friction. Only in your case friction is reduced because there is less drag because of the polished surface it is not harder to move along the surface. (assuming there is a force moving the object on top of the surface)
What type of surface cause less friction?
Smooth surfaces typically cause less friction compared to rough or uneven surfaces. Friction is reduced when there are fewer irregularities and bumps for objects to interact with, allowing for smoother movement. Examples of smooth surfaces that reduce friction include glass, ice, and polished metals.
How can friction overcome in a situation?
Friction can be reduced or overcome by introducing a lubricant between the surfaces, using smoother surfaces, or minimizing the force pushing the surfaces together. Additionally, changing the material of the surfaces in contact can also help reduce friction.
What are three ways friction can be removed?
Friction can be reduced by using lubricants to create a smooth surface between objects, employing rolling instead of sliding motion between surfaces, and using materials with low coefficients of friction.
When friction needs to be reduced?
Friction can be reduced by using lubricants, such as oil or grease, to create a barrier between surfaces. Using materials with low coefficient of friction, like Teflon or nylon, can also help decrease friction. Additionally, polishing or smoothing surfaces can reduce the contact area and therefore friction.
What are some ways friction can be reduced?
Friction can be reduced by using lubricants or oils between surfaces, using smooth surfaces, and reducing the force pressing the surfaces together. Additionally, materials can be coated with anti-friction coatings or using ball bearings and wheels to reduce friction in mechanical systems.
What types of surfaces produce the greatest amount of friction?
Rough surfaces typically produce the greatest amount of friction because there are more contact points between the surfaces, leading to increased resistance to motion.Smooth surfaces, on the other hand, tend to have less friction due to reduced contact points and smoother interactions between surfaces.
How can friction be reduced between two surfaces?
A lubricant such as oil, grease, graphite powder or PTFE can reduce the friction between two surfaces. Or using metal balls to space them and reduce the contact surface area as used in ball bearings.
Which surface gives the least friction?
A smooth and polished surface will typically have the least friction due to reduced roughness and irregularities that can impede motion. Materials like ice or Teflon are known for their low friction characteristics because of their smooth surfaces.
