Which phenomenon leads to the increased friction at the nanoscale compared to macroscopic levels?
-
Surface roughness
-
Viscous effects
-
Elastic deformation
-
Capillary forces
Correct Answer
A. Surface roughnessExplanation
Friction is generated due to the presence of microscopic asperities on material surfaces. Nearly all materials exhibit surface roughness at the microscopic level. When one object slides or moves over another, these small surface irregularities flex as the surfaces interact during motion, returning to their original positions as they pass each other.Rate this question:
