rubbing your hands together... eventually making heat.. and eventually fire! mu hah hah
yes it a foe but without friction in our like we cannot like. when there is no friction we cannot walk or no body can stand on the surface because were there is less friction we cannot stand it will be smooth
air friction also called air resistance or drag solid friction which is just normal friction and liquid friction like hydro-dynamics
It means what how can the friction be reduced. To answer this question, Friction can be reduced by devices like ball bearings, wheels and lubricants.
There are four types of friction: Fluid Friction (The friction caused by falling through air or water, or any other liquid etc), rolling friction (Like a ball rolling across the floor), static friction (The force it takes to begin something's movement), and sliding friction(Like pushing a box across the floor). In order of strongest to weakest it's Static, Sliding, Rolling, Fluid.
when i am ask is friction important i say the answer is yes. friction is important and can help people in many different ways. like cars for a example cars use friction to drive on the road. there is many different types of friction to; dry friction, fluid friction, lubricated friction, skin friction, internal friction, ect..... all of these types of frictions can be different a different way.

Friction is applied when a force occurs on two surfaces that are in contact with each other. There are many types of friction like fluid friction, static friction, rolling friction, and sliding friction. I am guessing this is a homework question. Aren't I right? Cool chick - OVER n OUT
friction (including fluid friction like air resistance) and gravity
you can use some anti-friction like lubricants (oil,gas).
Example of high friction is a really rough surface like sandpaper.
friction materials are the one which help in inducing friction to a friction-less object, like brake lining on the brake shoe is used for inducing friction between the brake shoe and the inner rim of the wheel.

The materials that, in general, change sliding friction to fluid friction are called lubricants. This class of materials includes oil, grease and the like.
