## What are the four methods to reduce friction?

Methods for Reduction friction:

• Make the surfaces little more smoother.
• Lubrication is another way to make a surface smoother.
• Make the object more streamlined.
• Reduce the Normal force acting between the surfaces in contact.
• Reduce the contact between the surfaces, so that less number of bonds will be formed.

## How can we reduce friction in machines?

Providing all bearings or wheels between the moving parts of a machine or vehicles reduce friction and allow smooth movement as rolling friction is less than sliding friction.

Which is used to reduce the friction in machine parts?

lubricant
Friction can be minimized by using lubricants like oil and grease and by using ball bearing between machine parts. A substance that is introduced between two surfaces in contact, to reduce friction, is called a lubricant.

### Why do we reduce friction in machine?

Friction is a necessary evil which causes a lot of wear and tear in machine parts that move against each other. It erodes the surfaces and destroys their symmetries. Hence, in such cases it is desirable to reduce friction.

### What are the examples of decreasing friction?

For example a slide in the park is polished to make its surface smooth and reduce friction. Due to reduced friction of a polished ,smooth slide, children can slide down easily. When oil or grease is applied between the moving parts of a machine ,a thin layer of oil or grease is formed between the two rubbing surfaces.

Which of the following is used to decrease friction?

Talc can be used to reduce friction when an object is sliding on a surface.

#### Which can be used to reduce friction?

Methods to reduce friction Using lubricants such as oil or grease can reduce the friction between the surfaces. When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings.

#### What are some common ways of decreasing friction?

– increases roughness of the surface – stop any relative motion – increases fluid viscosity.

What are three ways to decrease friction?

What are three ways to decrease the force of friction? Polishing the rough surface. Oiling or lubricating with graphite or grease the moving parts of a machine. Providing all bearings or wheels between the moving parts of a machine or vehicles reduce friction and allow smooth movement as rolling friction is less than sliding friction.

## What are some examples to reduce friction?

keep the surfaces clean. A drop of oil can reduce the friction many times. Sometimes this is what you want, so you use lubricants, sometimes this is not. Rinse the surfaces with some organic solvent or let the oil burn out. keep the surfaces cool. Hot surfaces typically have less friction – good example is how the car brakes will fade when hot

## What could be done to reduce the effect of friction?

jenny downing/CC-BY-2.0. The most common methods used to reduce friction between moving surfaces include polishing the surfaces that come into contact, lubricating the surfaces, using ball or roller bearings and streamlining. Friction is defined as the force that resists one surface from sliding or rolling against another surface. This means that friction is only present when one or both of the surfaces that are in contact are in motion.
