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

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

1. 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.

1. 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.

1. Draw a free-body diagram. 2. Determine the normal force ($F_n$). 3. Calculate the maximum static friction force ($F_{s,max} = mu_s F_n$). 4. Compare the applied force with the maximum static friction force to determine if the object moves.

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

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

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

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

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

A force that opposes the motion of surfaces sliding against each other.

A force that prevents surfaces from slipping when they are at rest relative to each other.
