Friction is not useful to most athletes (i.e swimmers, skiers, etc.) and friction is caused by the little imperfections and textures of objects against each other. You can reduce it by smoothing down one of the surfaces; like putting a very fine, smooth surface, or fabric over the skin of a swimmer to reduce friction.
Friction can be useful in car brakes to slow down or stop a vehicle safely. On the other hand, friction can be unwanted between moving parts in machinery, as it can cause wear and reduce efficiency.
The absence of friction is useful in situations like ice skating, where low friction allows for smooth gliding. It is also important in space travel, where friction is minimal, enabling spacecraft to move through space without resistance. Additionally, reducing friction in machinery can increase efficiency and reduce wear and tear on components.
Friction is useful in situations where we need to create traction or grip, such as when walking or driving. However, friction can be unwanted in scenarios where we are trying to reduce energy loss, such as in mechanical systems like engines where friction can lead to inefficiencies.
The type of friction that benefits in some or other way like smooth running of vehicles on the road is called Useful Friction whereas other wherein it becomes a causative factor for wear and tear or damage to the object in question.
Sandpaper is high in friction but is not considered useful in terms of being helpful in a general sense.

Brakes are meant to have a lot of friction and it's useful.
Ball bearings reduce friction in machinery by presenting a minimal surface area. This is because only very small areas of each ball are in contact with the surface. Therefore,the ball bearing is indeed a very useful thing for machinery to work.
yes because when they brake the friction is caused to reduce
I never heard of friction reducing friction. You can reduce friction by using lubricants, as well as using wheels (as in ball bearings).
Oil is mainly used to reduce friction between contacting surface, e.g., metal on metal - not to reduce air friction.
No Friction Runes Computers
Oil is used to reduce friction.
the factors that reduce in case of friction are the velocity and acceleration.
the friction from pushing the hull through the water is not useful as long as you're travelling.
