Question

Prove the force of friction depends on the nature of two surfaces in contact

Answer 1

Answer:

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. When two surface is rough then the friction is more because the interlocking is very strong in very rough surface.

Explanation:

Answer 2

Answer:

FRICTION IS NOTHING BUT INTERLOCKING OF IRREGULARITIES...

Explanation:

IF IT IS A SMOOTH SURFACE THERE WILL BE LESS IRREGULARITIES SO IT HAS LESS FRICTION.....

IF IT IS A ROUGH SURFACE THERE WILL BE MORE IRREGULARITIES SO IT HAS MORE FRICTION......
