There is more friction between the surfaces of 2 smooth surfaces than one smooth surface because there is more surface area.
It is on smooth surfaces because the amount of friction is less.
You can increase frictional forces by roughening the surfaces in contact, increasing the weight pressing the surfaces together, or using materials with higher coefficients of friction. To decrease frictional forces, you can use lubricants, reduce the weight pressing the surfaces together, or choose materials with lower coefficients of friction.
Friction actually depends on the roughness or smoothness of the surfaces of the object. Even some smooth objects that we usually see everyday (ex. glass, mirrorr,etc.) aren't that smooth when magnified by strong microscopes. They still have rough surfaces therefore they can also have friction. Factors that affect friction: 1.) Adhesion 2.) Surface roughness 3.)The area of an object which is in contact with the surface. The larger the surface in contact, the greater friction. 4.)The texture of the surface and/or the object. The rougher/more uneven the surface/object, the greater the friction. 5.) The weight on the surface. The larger the weight, the greater the friction 6.)The angle of the surface. The greater the angle of the surface, the greater the friction.
Colder temperatures can cause friction on surfaces to decrease as it can make surfaces more smooth and slippery. Rain or wet conditions can also reduce friction due to the presence of moisture on the surface. Additionally, icy or frosty conditions can lead to a decrease in friction as the ice or frost can create a slippery surface.
They would have to reduce friction by becoming perpendicular to the ground and reduce their surface area.
lubrication
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.
cartilage
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..!!
A tunic made of silk would have a smooth surface and would decrease friction due to its sleek texture. Silk is known for its soft, smooth feel against the skin, making it a good choice to reduce friction when worn as a tunic.
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.
To reduce friction, you can use lubricants to create a smooth surface between objects in contact. To increase friction, you can increase the force pushing the objects together or use materials with rough surfaces that grip each other more firmly.
To reduce friction on a plane, aerodynamic designs like smooth surfaces, streamlined shapes, and reducing surface roughness can help. Additionally, using lubricants on moving parts and ensuring proper maintenance can also help reduce friction.
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.
Two rough surfaces in contact will produce more heat due to increased friction compared to two smooth surfaces or a smooth and rough surface. Adding oil between two surfaces will reduce friction and heat generation.
Lubricants are applied to reduce friction between surfaces in contact with each other. They help to minimize wear and heat generation by providing a smooth film that separates and reduces the resistance between moving parts.
Friction is the force that will decrease if the surface of the ramp is made smoother. Smooth surfaces reduce friction by allowing objects to slide more easily with less resistance.
