Less friction is caused by surfaces with smooth textures, lubrication between the surfaces, reducing the contact force between the surfaces, and minimizing surface roughness. Additionally, reducing the speed at which the surfaces move past each other can also decrease friction.
Friction causes kinetic energy to be converted into heat energy.
Friction causes mechanical energy to be transformed into heat energy.
Friction between the wind and the Earth's surface causes the wind to slow down and change direction. This is known as surface friction, and it can create turbulent and erratic wind patterns near the surface. Wind speed tends to increase with height above the surface as friction effects become less significant.
The main causes of friction are roughness of surfaces, the force pushing the surfaces together, and the type of materials involved. Friction occurs when these factors create resistance to the motion of an object across a surface.
Friction is still there and gravity causes that, if there is no gravity there is no friction. Only in your case friction is reduced because there is less drag because of the polished surface it is not harder to move along the surface. (assuming there is a force moving the object on top of the surface)
less friction then what?
no limiting friction is not less than rolling friction
A lubricantis a substance introduced to reduce friction between moving surfaces. It may also have the function of transporting foreign particles. The property of reducing friction is known as Lubricity. (Slipperiness) This causes less friction.
rolling friction is 1/100 less than spliding friction
No, We cannot do work on friction less surface
Friction causes kinetic energy to be converted into heat energy.
TIs is
Friction causes mechanical energy to be transformed into heat energy.
That simply means that some energy is lost, due to friction and other causes.
No.
where is friction used in wrestling
Friction is not useful when ever we do not want it. Examples would be when two materials are rubbing against one another. The friction of ropes in pulleys eventually causes wear on both; friction of shoes or straps against the body causes blisters; friction airplanes travelling through the air - friction causes the plane to get hot; the moving parts of an engine get hot from friction...
