Question

8. Explain how the nature of the two surfaces in contact affect friction between them​

Answer 1

Answer:

irregulaties of the two surfaces interlock and thus cause friction in movement

hope it helps you

Answer 2

Answer:

The magnitude of friction depends on nature of the two surfaces. If the nature of two surfaces is smooth then friction between them is small because interlocking of smooth surfaces is less.

If the nature of two surfaces is rough then friction between them is strong because interlocking between rough surfaces is strong.
