what happens to the frictional force if the area of contact is changed

Answers

Answered by shrutijha0804

Answer:

Greater contact area means greater frictional force. If the contact area is proportional to the normal force, then this looks just like Amontons' Law with the frictional force proportional to the normal force. Of course this model "breaks" when the contact area can no longer increases
