Step 1:
: Understand the problem

We are asked to identify the units for the coefficients of static and kinetic friction.

Step 2:
: Recall the definition of coefficients of friction

Coefficients of friction are dimensionless (unitless) quantities that describe the resistance to motion between two surfaces in contact.

Step 3:
: State the units for coefficients of friction

The coefficient of static friction, often denoted by $\mu_s$, is a unitless quantity.
Similarly, the coefficient of kinetic friction, denoted by $\mu_k$, is also a unitless quantity.

Final Answer

Both the coefficient of static friction and the coefficient of kinetic friction are unitless.
