Friction
What is the difference between the
Static
and
Kinetic friction
forces?
Click all that apply.
Static friction occurs when there is relative motion between the contacting surfaces.
Static friction occurs when there is no perceptible relative motion.
Kinetic friction occurs when there is relative motion between the contacting surfaces.
Kinetic friction occurs when there is no perceptible relative motion.
What is the difference between the
Static
and
Maximum Static
friction forces?
Click all that apply.
The maximum static friction force is the amount of friction that must be overcome in order to initiate relative motion.
The static friction force exists when no perceptible relative motion is present.
The static friction force is determined by applying the equilibrium equation to the system.
The maximum static friction force is determined by the equation
