Because friction stops momentum of force from moving the bike
Friction and pressure.
No. Some of it is lost as friction.
it is harder because there is less friction with lubrication -which is what water is -and you need friction for the breaks to work

Yes, it is scientifically shown that bicycle helmets do work. They help to absorb the impact from a crash and protect your skull and brain.
Oil can reduce friction between moving parts, and protect exposed metals from rust.
Friction is helpful so you dont fall and friction helps things work much better than others. friction can also be helpfull when someone is driving. for an example on a slippery road frictio between the tires and the road stops the cars from sliding off the road and crashing. In sports friction stops the ball from going on forever. without friction we would just keep going on and on with out stopping. friction helps stop a bicycle from going on forever when we push the brakes in a bicycle it creates friction, which slows us down to a stop.
There are several force transitions going on in the linkage, but in the actual brake you are using friction to turn speed into heat.The most important one is friction, but apart from that there's a lot of mucking about with mechanics in order to translate the motion by the hand at the lever into something capable of slowing down a wheel.There are several forces needed to make a bicycle brake work IRL. But I assume the one you're asking about is FRICTION.
a bicycle for transportation
it doesnt work, it breaks it doesnt work, it breaks it doesnt work, it breaks
Friction will work against force
No, friction decreases gas mileage. If you are talking about Friction motor treatment then it is just another in a long line of products claiming to increase mileage. None of them work, period.
