Want this question answered?
Since friction means a contact force, the nature of contact will influence friction force. Smoothness of objects affect the friction force. However, as contact pressure rises, the friction does not rise.
Generally, the higher the contact force, the higher the friction.
It is a contact force.
The force of friction does, but the coefficient of friction does not.
