You can reduce friction in a bicycle by:
Well.. There is surface friction from the tires on the road, there is air friction from the bike itself ,, more air surface friction if your on it.. Then there is mechanical friction through the resistance of the, chain, bearing assembly grease in axle.
It made clothing more practical.
it rubs the steel because its friction!
No effect
No
The force of friction needs to touch an object to have an effect. Friction occurs when two surfaces are in contact and one surface resists the motion of the other surface. It is this resistance that allows friction to have an effect on objects in contact.
They made womens clothing more sporty
Bicycling and other sports had a significant effect on women's clothing in the 1800's. New fashion trends had to emerge so as to accommodate women who were involved in such events this was when shorts and trousers became popular for women.
Friction slows down objects by in some capacity rubbing against them
yes
Friction is independent of speed once an object is moving since faster does not mean more friction.
The friction angle of the mixture increases the relative density.
