Question

On which factors force of friction depends i. mass of body ii. Nature of surface iii. Both i and ii ​

Answer 1

the opposite direction of motion attraction is called frition ..

Answer 2

Explanation:

3. Both

Because more the mass of the body more the friction due to gravitational force..

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. When the surfaces are rough the friction is more..
