# What are 2 ways to reduce friction and 2 ways to increase friction?

## What are 2 ways to reduce friction and 2 ways to increase friction?

To reduce friction we can make the surfaces in contact smooth. Also adding a lubricant to two surfaces in contact reduces friction between them. Grease is added between the moving parts in machines, to reduce friction. Another method of reducing friction is by using bearings.

## What are three ways friction decreases?

Force | Short/Long Answer Questions Q23) List three ways of reducing friction. Polishing the rough surface. 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 3 ways friction can be reduced Class 8?

Methods of reducing friction

• 1)Friction can be reduced by making the surface smooth by polishing.
• 2)Friction can be reduced by applying lubricants (like oil or grease) to the rubbing surface.
• 3)Friction can be reduced by using wheels to move objects.

### What is the most common way to reduce the friction?

Answer: The most common way to reduce friction is to oil or grease the surface .

### What are 5 ways to reduce friction?

Methods for decreasing friction:

• Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction.
• Lubrication is another way to make a surface smoother.
• Make the object more streamlined.
• Reduce the forces acting on the surfaces.
• Reduce the contact between the surfaces.

What are 2 ways to increase friction?

There are two methods of increasing friction: one is by making the surfaces rough and the other by increasing the mass of the object that is moving. For example, the tyres of vehicles have treads (these are the ‘designs’ that you can see on the tyre surface), which increase the friction between the tyre and the road.

#### What are the 2 types of friction?

There are two main types of friction, static friction and kinetic friction. Static friction operates between two surfaces that aren’t moving relative to each other, while kinetic friction acts between objects in motion.

What are the most common ways to reduce friction?

What Are Ways to Reduce Friction? What Are Ways to Reduce Friction? 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.

## How does lubricant reduce friction on a surface?

Lubricant are substances applied onto surfaces to reduce friction. It can reduce heat generation and also ensure smooth sliding. Lubricants are mostly semi-solid paste like materials that reduce dry sliding friction. Mechanism of how lubrication reduces friction

## How are ball bearings used to reduce friction?

Polishing : unevenness of the surfaces can be reduced by polishing, thereby reducing the friction. Use of ball bearings: In rotating machines, shafts are mounted on ball bearings. By doing so, rolling friction occurs lesser than sliding friction, thereby reducing the friction.

Why do smooth surfaces have less friction than hard surfaces?

The brakes also use friction to control the deceleration of the car. Eventually, the parts that are subject to friction will wear down and need to be replaced. It is beneficial to reduce the friction between surfaces to make movement easier or reduce the wear and tear on a surface.

### What are the three ways of increasing friction?

• Grooves are made in the soles of shoes to increase friction and prevent slipping.
• Treads are made in the tyres of vehicles to increase friction and prevents skidding of vehicles on wet road.
• Spikes are provided in the shoes of players and athletes to increase friction and prevent slipping.

### What things can reduce friction?

Friction between moving parts is usually reduced by introducing a substance between the moving surfaces. This process is called lubrication. The substance introduced is called a lubricant. Common lubricants are oil and grease. Ball bearings are also used to reduce friction. Ball bearings change sliding friction to rolling friction.

How can we increase and reduce friction?

Method of decreasing and increasing friction By polishing: Friction between two surfaces can be reduced by polishing them. Ball-bearing: As the rolling friction less than the sliding friction consequently in rotating machinery, the shafts are fixed on the ball bearing so that the friction can be reduced considerably.

#### What are some ways to increasing friction?

The three methods of increasing friction are: 1.) By applying more force to the object, 2.) By increasing the mass of the object that is causing friction, and 3.) By creating a rougher point of contact.
