Give two similarities and dissimilarities between friction and viscosi

1.	Give two similarities and dissimilarities between friction and viscosity.
Answer» Solution :Similarities: (i) viscosity exist when there is relative motion between LAYERS of the LIQUID. Similarity friction exists between two solids surfaces in CONTACT when there is a relative motion between them. (ii) Viscosity depends on the nature of the LAYER of the fluid and friction ALSO depends on the nature of the solid surfaces in contact. Dissimilarities : N/A
