What parts of a bicycle is friction necessary and what parts are not necessary?
The bearings don't need friction, but everything else does. It there wasn't any friction it'd be impossible to bolt anything together.
How friction influenced the invention of the bicycle?
Tires, grips, pedals and brakes needs to have high friction, while all rotating parts needs to have low friction.
Why is it important that maglev trains do not touch their track?
I'm not too sure about the advanced physics of this, but I know that it is desired for Maglev trains to not touch the track so that their speed can be maximised, and so there is no wear and tear of the track and contact. The speed would be maximised because if you don't touch the track there is no friction. Even wheels are slowed by friction so the only way to completely eliminate it is to have no friction.
Where on a bicycle friction can be a nuisance?
the gears and where the axis of the wheels
Why does oil make a bicycle work better?
Oil can reduce friction between moving parts, and protect exposed metals from rust.
What part of a bicycle is a useful friction?
The brakes! And the tires (no friction = no traction).
Where on a bicycle is friction not important?
In the bearings, where you want as little friction as possible.
What Suppose a bicycle was coasting on a level surface and there was no friction. What would happen to the bicycle's speed?

What part of a bicycle has a small amount of friction?
The bearings
How does a friction effect with bicycling?
friction makes riding a bike possible. When the tire presses on the ground, friction acts against the rotation of the tire, fixing the lowest point of the wheel on the floor. This force is transmitted to the axel of the wheel and is what propels the bicycle forwards.
How does friction help the breaks in a bicycle work?
Because friction stops momentum of force from moving the bike
What principle of fource is used on bicycle's brake?
Friction and leverage.
