Want this question answered?
Polishing the surface or coating it with a lubricant is a way of reducing friction. To increase friction just hammer some ridges on the surface.
Lubrication, is one way.Two ways to reduce friction are :.Lose weight.Wet the surface
Reduce contacting surface area between the two objects, and to use lubrication.
Its reduce by following ways By polishing the surface use lubricants by streamlining by air cushion by converting sliding friction in to rolling friction
Apply a larger force. Make the object less massive. Decrease air resistance acting on the object. Decrease the coefficients of friction by using a 'smooth' surface, where friction is negligible.
Rougher surface and more weight to the object increases friction
Polishing the surface or coating it with a lubricant is a way of reducing friction. To increase friction just hammer some ridges on the surface.
1)increasing the roughness of the surface 2)increasing the mass of the object
There are different ways through which helpful friction be increased. The easiest way is using coarser or rougher surface to increase resistance.
one way is to make the surface rougher and another way is to increase the force pushing the surfaces together.
Use a surface that has a higher coefficient of static/kinetic friction and/or add more force downwards on the object.
find a materials with a high coefficient of static friction and use them against each other ( like rubber dry concrete ) and bound them to the object and the surface it rests on. Increase the normal force by adding mass on the object or applying a perpendicular force to the surface of the object.

Okay 2 ways for the friction to increase is speed and non lubricant
Lubrication, is one way.Two ways to reduce friction are :.Lose weight.Wet the surface
Reduce contacting surface area between the two objects, and to use lubrication.
1) using a lubricant film between moving parts. 2) using low friction materials, such as Teflon.3) reducing surface roughness.
