Question

give an example to show that friction depends on the force with which the two forces are pressed together

Answer 1

Example.
When we gently push abook on a table,it stops after moving for some distance because friction opposes relative motion between the surfaces of the book and the table If we apply the force along the right direction,the friction acts along that direction in both cases,the force opposes the motion of the book.
