Question

Which factors affect friction,? ​

Answer 1

(I) the adhesion between body surfaces

(ii) roughness of the surface

(iii) deformation of bodies

Answer 2

The type of the two surfaces in contact, whether smooth or rough, and the strength with which two surfaces in contact are attached, or the weight of the objects

Explanation:

• We've seen that walking on a dry floor is quite easy because it's rough by nature and has more interlocking between the surfaces. However, if we pour water on the floor, it will fill up the space between the tiles, allowing them to interlock. As a result, we will begin to slide or slip on the floor since it is smooth.
• Second, friction is determined by the strength with which the surfaces are linked to one another, which is determined by the normal force between them. We now know that normal forces are proportional to the object's weight. As a result, when we try to slide a heavy body across a surface, the weight causes more interlocking between two surfaces.
