What things create little friction?
Objects which cause little amount of friction are smooth objects such as glass and other objects which are man-made (most of the time). However, there are many objects which are natural which can create minimal amounts of friction too.answ2. Very often, using two different materials will give superior wear characteristics - = low friction. e.g. White metal bearings against steel, Steel against wood (in ship's prop shafts).I'd expect glass against glass to have a high friction coefficient.
Five examples of surfaces that have very little friction between them?
There are several examples of surfaces that have little friction between them. They are water against a boat, crude oil in water, ball bearings, roller bearings, and graphite.
What are surfaces with very little friction?
Soap surfaces have very little friction.
When do you need a little friction?
You need a little friction when you are going down a water slide and much more
Where is friction not useful and how to reduce it?
Friction is not useful to most athletes (i.e swimmers, skiers, etc.) and friction is caused by the little imperfections and textures of objects against each other. You can reduce it by smoothing down one of the surfaces; like putting a very fine, smooth surface, or fabric over the skin of a swimmer to reduce friction.
Is pushing your little brother on his tricycle work?
Yes it is work. Your brother may already be moving, but pushing him will make him go faster.
Why does your car slip and slide?
Because your tires have little friction against ice and snow!
What has little and what has lots of friction?
Ice has little friction. Sandpaper has lots of friction.

Is heat little friction or is it great friction?
heat is really half of friction
How does friction effect a toy model car?
it depends on what the car is doing, everything is effected my gravity which is pushing down and the surface its touching(wheels to the pavement) is causing friction, then when its rolling you also have rolling mass and contact patch of the wheels and weight.. you need to be a little more specific
Can you give me a sentence with the word punish?
I hate to punish my children, but sometimes I have to.

Where on a bicycle is friction not important?
In the bearings, where you want as little friction as possible.
