Question

name 4 ways by which friction can be reduced between two surfaces in contact​

Answer 1

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.

Explanation:

Answer 2

Answer:

1. Lubrication: Lubricants are substances that apply to surfaces for reducing friction. An example of lubricant is oil.
2. Reduce contact between surfaces
3. Reduce pressure or weight on the object
4. Make the sliding surfaces smoother by grinding or using sandpaper.

Explanation:

Friction is the force that resists the sliding or rolling of one substance over another. There are various ways to reduce friction.
