Question

write two methods to decrease friction .​

Answer 1

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 2

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. ...

-Make the object more streamlined. ...

-Reduce the forces acting on the surfaces. ...

-Reduce the contact between the surfaces.
