What is the effect of increasing the normal force on kinetic friction?

Increasing the normal force increases the magnitude of the kinetic friction force.

What happens when the applied force exceeds the maximum static friction?

The object begins to move, and kinetic friction takes over.

What is the effect of friction on the work-energy theorem?

Friction does negative work, converting kinetic energy into thermal energy, thus reducing the total mechanical energy.

What happens when a car tire rolls without slipping?

Static friction between the tire and the road provides the centripetal force needed for circular motion.

What is the effect of a higher coefficient of static friction between two surfaces?

It requires a greater force to initiate movement between the surfaces.

How do you calculate kinetic friction ( $F_k$ )?

$|F_k| = |mu_k F_n|$ , where $mu_k$ is the coefficient of kinetic friction and $F_n$ is the normal force.

How do you calculate the maximum static friction force ( $F_{f,s,max}$ )?

$F_{f,s,max} = mu_s F_n$ , where $mu_s$ is the coefficient of static friction and $F_n$ is the normal force.

What is the process to determine if an object will move when a force is applied, considering static friction?

Calculate the maximum static friction force ( $F_{f,s,max} = mu_s F_n$ ). 2. Compare the applied force ( $F_{applied}$ ) with the maximum static friction. 3. If $F_{applied} > F_{f,s,max}$ , the object will move; otherwise, it remains at rest.

What are the steps to solve a problem involving kinetic friction on a horizontal surface?

Draw a free-body diagram. 2. Determine the normal force ( $F_n$ ). 3. Calculate the kinetic friction force ( $F_k = mu_k F_n$ ). 4. Apply Newton's Second Law to find the net force and acceleration.
