If you were roller-skating you don't need friction because it slows you down.
Well you want friction between the wheels and the floor (so you do not slip sideways) but not between the wheel and the axel (thats why you have ball bearings there to reduce rolling friction).
If you are ice skating you do not want friction between the blade of your skates and the ice.
Dont rub your hands fast just go slower for less friction or slowing down the car is less friction also. mainly slowing down friction is just slowing down somthing your doing. to do or make somthing
We always want friction. If there was no friction, you could never drive a car, because its tires would never rub against the ground to get it moving. You could never chew because you use your tongue to move the food around in your mouth; if there was no friction, you couldn't move it around. Just think about situations where movement starts or stops--these situations would no longer exist.
Nope. Everything must have friction even if it is smooth. In a microscopic level every surface or fluid is rough and even. When an object is rough it must have friction.
You don't want friction when you are sliding. This is how we get carpet burns and other types. when you slide friction acts against you and it becomes a burn.
You may want to reduce friction in an engine.
There are many applications that would benefit from less friction. Any kind of motion where heat is produced but not intended would benefit from less friction. Some examples: 1. the contact point between the piston and wall in an engine produces less heat and more power with less friction 2. air flow over a car's exterior, over a plane's exterior, over a rockets exterior results in reduced drag (air resistance) with less friction 3. the space shuttle could definitely use less friction with the atmosphere during re-rentry 4. electrical conductors are more efficient as friction decreases 5. if friction were 0, the perpetual motion machine would be possible
hard place has more friction and smooth place has less friction
Because if there is less friction, the road would be very slippery, therefore more dangerous
You can change friction by the material. e.g ice, low friction. carpet high friction.Or you could add a lubricant :D
Antaganism
You want less friction. Then you will go faster.

friction
no limiting friction is not less than rolling friction
less friction then what?
rolling friction is 1/100 less than spliding friction
hard place has more friction and smooth place has less friction
Examples of SLIDING FRICTION is pushing a heavy rock in your path, or moving a box on the floor.

No, We cannot do work on friction less surface
