how to decrease friction
(I need more points please )
Answers
Answer:
By polishing the surface, as polishing makes the surface smooth and friction can be reduced. Using lubricants such as oil or grease can reduce the friction between the surfaces. When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings
Answer:
Methods for decreasing friction:
Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction.
Lubrication is another way to make a surface smoother. A lubricant is a slippery substance designed to reduce the friction between surfaces.
Make the object more streamlined. A streamline shape is one that allows air or water to flow around it easily, offering the least resistance.
Reduce the forces acting on the surfaces. The stronger the forces acting on the surfaces, the higher the friction, so reducing the forces would reduce the friction.
Reduce the contact between the surfaces. Spheres are the best shape for reducing friction because very little of a spherical object is in contact with the other surface.
