Question

With the help of an activity, explain the effect of friction on the nature of surface in
contact​

Answer 1

Friction depends on the nature of the two surfaces. It depends on smoothness or roughness of the two surfaces which are in contact of each other. When two surfaces are in contact are smooth, then the friction between them is small because the interlocking of smooth surface is less.

please mark as brainliest answer

Answer 2

Answer:

basically, the friction depends on smoothness or roughness of the two surfaces which are in contact of each other. when two surfaces are in contact smoothy then the friction b/w them too small. it's happens just bcoz of interlocking of less smooth surface.
