The friction force is given by:
Where μ is the coefficient of friction (static or kinetic) and
is the normal force. So we say the friction force is directly proportional to the normal force with a constant of proportionality equal to the coefficient of friction.
Where μ is the coefficient of friction (static or kinetic) and
