How does the force of friction change when the normal force changes?

1 answer:

8 0

The friction force is given by:

$F_f= \mu F_N$

Where μ is the coefficient of friction (static or kinetic) and $F_N$ 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.
