What are the steps to calculate kinetic friction?

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

What are the steps to determine if an object will move due to an applied force and static friction?

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.

How do you determine the normal force on an inclined plane?

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.

Describe the process of kinetic friction converting kinetic energy to thermal energy.

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.
