Why do wheels need ball bearings to reduce friction?
because there is grease between them......
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.
Does sand reduce friction?
No, sand does not reduce friction but increase 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.
How can you reduce and increase friction?
Lubrication to reduce friction. To increase friction step on the brakes.
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).
What are two means by which friction may be reduced?
Lubrication and ball bearings both reduce friction.
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.
What is role of ball bearing in bicycle?
To reduce friction between surfaces.
Three examples of where ball bearings are used to reduce friction?
in machineare parts
Why do wheels need ball bearings to reduce friction?
because there is grease between them......
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 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 two things could you do to increase the momentum of the ball?
Reduce friction or increase slope.
How ball bearing reduce friction?
Bearings reduce friction by providing smooth metal balls or rollers, and a smooth inner and outer metal surface for the balls to roll against. The smoothness of the metal reduces the friction and the surface area.
What is ball bearings?
it is a mechanical equipment to reduce friction. It is used in moving parts very often.
Does sand reduce friction?
No, sand does not reduce friction but increase friction.
