Quizplus · Accepted Answer

The force of static friction is proportional to the normal force between two surfaces, according to the equation $f_s = \mu_s N$, where $f_s$ is the static friction force, $\mu_s$ is the coefficient of static friction, and $N$ is the normal force. This relationship does not inherently depend on the contact area, and the force of static friction can be either larger or smaller than the applied force, depending on the situation, until it reaches its maximum value, at which point motion begins.
