## Why is friction evil

Answered By: Colin Clark Date: created: Mar 05 2022

Frictional force causes a lot of losses in general upkeep and wear and tear of machinery.

Hence it is considered as a evil.

But almost all crucial tasks cannot be carried out without the presence of friction.

Hence it is considered as a necessary evil ..

## What are 3 ways you can reduce friction

Answered By: Lewis Mitchell Date: created: Jan 07 2022

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 is easier rolling or sliding

Answered By: Leonars Wright Date: created: Oct 03 2021

When an object rolls over the surface of another object ,the resistance to its motion is called rolling friction. It is always easier to roll than to slide an object over another object.So rolling friction is much less than the sliding friction.

## What are the five disadvantages of friction

Answered By: Bryan Coleman Date: created: Feb 23 2022

Disadvantages of friction:Friction produces a lot of heat in various parts of the machinery and this leads to wastage of energy as heat.Opposes motion, hence more energy is needed to overcome friction.Noise production in machines is irritating as well as leads to energy loss.Forest fires are caused due to friction between branches of trees.More items…

## How we can reduce friction

Answered By: Jayden Scott Date: created: Nov 20 2021

By polishing the surface, as polishing makes the surface smooth and friction can be reduced. 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.

## Why do we need to decrease friction

Answered By: Seth Rivera Date: created: Aug 25 2021

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. Friction is reduced by lubricating surfaces to decrease the friction.

## Why is friction called a perverse force

Answered By: Lewis Campbell Date: created: Jun 01 2021

Accepted Answer: Frictional force always acts in the direction opposite to the direction of motion, i.e., it always opposes motion. Hence, it is called a perverse force.

Answered By: Ethan Mitchell Date: created: May 31 2022

Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.

## Is friction useful or harmful

Answered By: Jackson Hernandez Date: created: Apr 15 2021

Without friction, a car is useless. However, friction can also cause problems in a car. Friction between moving engine parts increases their temperature and causes the parts to wear down. Friction can be both harmful and helpful, so it may be necessary to decrease or increase friction.

## What is importance of friction

Answered By: Rodrigo Torres Date: created: Nov 10 2021

Friction is important also for these reasons: (1) It causes air in the PBL to converge toward low pressure and diverge from high pressure (friction causes PBL air to flow toward low pressure) (2) friction is a little stronger over land surfaces than over water surfaces since land surfaces have a more rough and vertical …

## Where is friction not useful

Answered By: Andrew Wilson Date: created: May 07 2022

Friction can also be unhelpful. If you do not lubricate your bike regularly with oil, the friction in the chain and axles increases. Your bike will be noisy and difficult to pedal. When there is a lot of friction between moving parts, energy is transferred to the surroundings, causing heating.

## Which is wasteful friction

Answered By: Connor Perez Date: created: Mar 17 2022

Answer. Though friction is said to be a waste of energy in most of the times, it is really useful at many times in regular life. We need to increase the frictional force while pressing the brakes of a car or a bicycle to stop it at the right time.

## What is the main cause of friction

Answered By: Wyatt Hayes Date: created: Sep 01 2021

Causes of Friction: Friction is a force that resists the relative motion between two objects or materials. The causes of this resistive force are molecular adhesion, surface roughness, and deformations. Adhesion is the molecular force resulting when two materials are brought into close contact with each other.
