Answer 1

The magnitude of the force of friction between two bodies, one lying above the other, depends upon the roughness of both the bodies.

Explanation:

1. Friction is the force that acts opposite in direction to the motion of any object.
2. Friction is caused due to the contact between different bodies whole magnitude depends on the roughness of the surfaces of bodies.

Answer 2

Surface in contact and the weight of the object

1. The magnitude of the force of friction between two bodies, one lying above the other, depends upon the roughness of the Surface in contact and the weight of the object

2. If the surface of an object is going perpendicular to the force then the friction is proportional to the component.

3. Force of an object is directly proportional to the weight of the object

4. So, friction depends on weight, mass, the way the surface is in and the condition of the area of contact.
