Question

friction depends upon area of contact yes or no prove by an experiment also friction is independent on normal force between surface of contact where friction exists Do you agree discuss​

Answer 1

Answer:

friction is independent of the area of contact.

Ex: Take a wooden cuboidal box. Apply some force to it while it is resting on the side with larger surface. Now turn the box on the side with lesser area and apply the same force. You will notice that the frictional force remains same ( although the pressure will vary) .

friction is dependent on the Normal force.

f=μmg

Normal reaction=mg

therefore,

f=μN

this can be proved using a graph too.

hope it helped:)
