It depends on The friction force depends on two factors:

a) The materials that are in contact. The two materials and the nature of their surfaces. ...

b) The force pushing the two surfaces together. Pushing the surfaces together causes the more of the asperities to come together and increases the surface area in contact with each other

Answer 2

where N =normal force

u = friction constant

so friction force depend on normal force and friction cinstant of body
