1: Identify the surfaces in contact. 2: Determine the normal force (N). 3: Find the coefficient of kinetic friction ($\mu_k$). 4: Calculate $F_k = \mu_k N$.

1: Calculate the maximum static friction force ($f_{s,max} = \mu_s N$). 2: Compare the applied force (F) to $f_{s,max}$. 3: If $F > f_{s,max}$, the object moves; otherwise, it remains at rest.

1: Identify the angle of the incline ($\theta$). 2: Calculate the normal force using $N = mg \cos\theta$, where m is the mass and g is the acceleration due to gravity.

1: An object slides across a surface. 2: Kinetic friction acts opposite to the motion, doing negative work. 3: This work converts kinetic energy into thermal energy, increasing the temperature of the surfaces.

1: Draw a free body diagram. 2: Calculate the normal force. 3: Calculate the kinetic friction force. 4: Determine the net force along the incline. 5: Use Newton's Second Law ($F_{net} = ma$) to find the acceleration.

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.

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

The force that opposes the start of motion between two surfaces in contact.

A dimensionless quantity representing the 'roughness' between two surfaces in kinetic friction. It relates the kinetic friction force to the normal force.

A dimensionless quantity representing the 'stickiness' between two surfaces in static friction. It relates the maximum static friction force to the normal force.

The force exerted by a surface that is supporting the weight of an object. It acts perpendicular to the surface.
