What are the four factors on which friction depends ?

Expert Answer:

Friction depends on two factors:

(i) Nature of the surfaces in contact i.e. whether surface is rough or smooth. 

  •      Friction depends on the smoothness or roughness of the two surfaces which are in contact.
  •       A rough surface produces greater friction as compared to a smooth surface.

(ii) Friction depends on the force with which the two surfaces are pressed together. 

  •       Friction also depends on the weight of an object.
