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).


Why are ball bearing used in wheels?

Machine parts use ball bearings to reduce friction, making it easier to move the moving parts and producing less wear on the parts.


What do we use in bicycle wheels to reduce friction?

We use ball bearings in bicycle wheels to reduce friction. Ball bearings are small, metal balls that are placed in between the moving parts of the wheel hub to help it spin smoothly and with minimal resistance. This helps improve the overall efficiency and performance of the bicycle.


Why do you use ball bearings?

Because they're a good way to reduce friction and help wheels and axles to spin smoothly and effortlessly.


What friction is the type of friction produced by wheels or ball bearings?

Rolling friction is the type of friction produced by wheels or ball bearings. It is typically lower than static or kinetic friction, as it involves the rolling motion of one object over another. This type of friction results in smoother movement and less energy loss compared to sliding friction.


What is a type of friction that is reduced by wheels and ball bearings?

Rolling friction is a type of friction that is reduced by wheels and ball bearings. It is the resistance that occurs when one object rolls over another object, and is typically lower than sliding friction.


What are two means by which friction may be reduced?

Lubrication and ball bearings both reduce friction.


What are two ways you can reduce friction in a machine?

A lubricant such as oil and ball bearings are just (2) methods of reducing friction.


What stuff can reduce friction?

* lubricanting like oil, greese, etc. * by using ball bearing * polishing * stream lining Water can reduce friction. Also, round things like wheels and straws can reduce friction. Things that are placed on wheels, straws, pencils, etc. can move far with a soft push.


Three examples of where ball bearings are used to reduce friction?

in machineare parts


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.


Why we use ball baring in wheels?

Ball bearings are used in wheels to reduce friction between the moving parts of the wheel, allowing it to rotate smoothly and efficiently. The design of ball bearings helps distribute the weight and load evenly, making it easier to move the wheel with less effort. This can lead to improved performance, increased speed, and longer durability of the wheel.
