Well, it certainly can not speed things up (that would violate II law of thermodynamics). Motion can be converted into randomized heat, but randomized heat can never be converted into motion. So, yes, its 'always' slows things down (although not always, when object is stationary friction does nothing).

∙ 15y agoIf a space shuttle is entering the earth's atmosphere, the friction between the shuttle and the atmosphere could cause enough heat to burn up the shuttle. that's why the ceramic heat tiles were created. :) hope this helped! ;D

∙ 14y agoNo. The tires on cars would not grip the road without friction. This is just one of many examples where friction is not a problem.

∙ 13y agoFriction is what makes it hurt, and you use KY to reduce that friction.

∙ 12y agono, actually many inventions or things work on the basis of friction for example a pen it works on the basis of friction.Anything that would once be in motion would never stop.

∙ 12y agoNo. Without friction things like the brakes on a car wouldn't work.
Wiki User
∙ 16y agoYes, friction always exists.

What are the problem caused by friction?
The problem caused by the Friction * The heat is produced. * efficiency of a engine is decreased. * The mechieneries will get old quickly. * Loss of energy in the form of heat.
If the coefficient of static friction is 0.75 what is the coefficient of dynamic friction?
less than 0.75 and in exceptional cases equal to 0.75,eg.when the friction between two teflon surfaces is considered
Why is friction called necessary evil?
Friction is called a necessary evil because we cannot completly avoid it an actually it is used in many cases.
What things can friction cause?
Friction can cause things to change direction, slow down or stop. It also produces heat, and in extreme cases sparks.
What role does friction play in energy transformations?
In many cases, energy is wasted due to friction - meaning that useful energy is converted into unusable energy.
What is more sliding friction or static friction?
static friction is higher in most cases, if you're talking about the coefficient of static or kinetic friction
Is friction a problem?
no of Corse not

Why is friction a problem for machines?
it can create lots of heat
When might friction be a problem?
when it causes to much heat
What problem did the wheel and axle solve?
To reduce friction
Why is friction called a evil?
friction is called a necessary evil because we cannot completly avoid it an actually it is used in many cases.

less than 0.75 and in exceptional cases equal to 0.75,eg.when the friction between two teflon surfaces is considered
Is it true that rolling friction always reduces the net force acting aginstan objects's motion to zero?
Friction can be reduced, but in most cases there is no practical way to reduce friction to zero.
Why friction is problem?
Friction can be a problem as it slows down the movements of objects. It may also stop the movement of object and as such, a bigger force is needed to make the object move faster.
Why is friction called necessary evil?
Friction is called a necessary evil because we cannot completly avoid it an actually it is used in many cases.
