Question

On which of the following factors, friction between two objects/surfaces does not depend?

• A. temperature
• B. surface roughness
• C. intemolecular interactions
• D. mass of objects

Answer 1

The correct option is A temperature

Frictional force between two objects depends on surface roughness of the two objects, the intermolecular interactions between the surfaces in contact and mass of the objects as well. Friction between two objects does not depends on temperature of either of the objects.
