when we are moving on rollers .....only a very small part of the roller is in contact with the ground ......this means only a very smaal part of the rovver get s stuckein the uneven surface of the ground ...as a result there is less friction..!!
yes because when they brake the friction is caused to reduce
Oil is used to reduce friction.
the main reason for doing so is that the surface becomes smooth n in terms of science to reduce "friction" that wud exist between the board n the striker due to which it will move more swiftly with lee deployment of power..!!
How does the flow of air reduce friction of the hovercraft in motion?
Professional bike riders want to reduce friction, because friction is a force of two objects rubbing up against each other, therefore slowing you down.
Lubrication: Applying a lubricant such as oil or grease between surfaces to reduce friction. Smoothing: Ensuring that the surfaces in contact are flat and smooth to minimize friction. Using ball bearings or rollers: Introducing rotating elements like ball bearings or rollers to reduce friction between moving parts.
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.
To reduce friction, you can use lubricants such as oil or grease, polish the surfaces to make them smoother, use ball bearings or rollers, or introduce a layer of Teflon or other low-friction material between the surfaces in contact.
Lubricants are substances used to reduce friction between surfaces in contact with each other, while rollers are mechanical components that rotate on an axis to facilitate movement or transportation of objects. Rollers can be coated with lubricants to further reduce friction and improve their performance.
Two ways to reduce friction are to use lubricants, such as oil or grease, to create a smooth surface between moving parts. Another way is to use ball bearings or rollers to minimize the surface area in contact and 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.
You can decrease friction on an object by using lubricants such as oil or grease, polishing or smoothing the surfaces in contact, or using ball bearings or rollers to reduce direct surface contact.
Three methods to reduce friction between two surfaces are using lubricants like oil or grease to create a slippery layer between the surfaces, using ball bearings or rollers to reduce direct contact, and using smooth materials or coatings on the surfaces to minimize friction.
The four ways to decrease friction are: lubrication (using substances like oil or grease to reduce friction), using smoother surfaces, reducing the weight pressing the surfaces together, and using ball bearings or rollers to replace sliding friction with rolling friction.
You could add lubricants like oil or grease to reduce sliding friction on the moving parts of a machine. Additionally, using materials with lower coefficients of friction or adding bearings or rollers can help to minimize sliding friction. Regular maintenance and cleaning of the machine parts can also help prevent friction buildup.
You can reduce friction between two objects by using lubricants such as oil or grease, polishing or smoothing the surface of the objects, or using ball bearings or rollers in between the objects to minimize direct contact. Additionally, lowering the force pressing the objects together can also reduce friction.
The friction between two objects can be decreased by using lubricants such as oil or grease, which create a slippery layer between the surfaces. Alternatively, polishing or smoothing the surfaces can reduce friction by removing rough areas that create friction. Using ball bearings or rollers can also reduce friction by allowing smooth movement between the objects.
