Question

the property of the surfaces in contact that give rise to friction

Answer 1

plane or smooth and rough surface are the property surface.

Answer 2

There are three vital factors that leads to friction. Before directly diving into the factors let us understand what friction is and why it is caused so whenever there is a kind of relative motion then the two objects involved resist each other and this is due to friction.

The three factors causing friction are as follows:

1. Adhesion in between molecules

2. Roughness of the surface.

3. Irregularity and deformation of the surface.
