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.
What else can I help you with?
Where can friction can be both useful and unwanted?
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.
When is the absence of friction useful?
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.
When is friction unusfel?
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.
What are the differences between useful and harmful friction?
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.
What is high in friction but is not useful?
Sandpaper is high in friction but is not considered useful in terms of being helpful in a general sense.

Does brakes on a bicycle have a lot of friction or not much and is it useful or not useful?
Brakes are meant to have a lot of friction and it's useful.
How do ball bearings reduce friction in machinery?
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.
Do wheels reduce friction?
yes because when they brake the friction is caused to reduce
What kind of friction can help reduce friction?
I never heard of friction reducing friction. You can reduce friction by using lubricants, as well as using wheels (as in ball bearings).
How does oil reduce air friction?
Oil is mainly used to reduce friction between contacting surface, e.g., metal on metal - not to reduce air friction.
Is friction useful with computers?
No Friction Runes Computers
What does a bit of oil reduce in science?
Oil is used to reduce friction.
What are the factors that reduce in case of friction?
the factors that reduce in case of friction are the velocity and acceleration.
When can friction not be useful in a boat?
the friction from pushing the hull through the water is not useful as long as you're travelling.
