$\huge\mathfrak{\blue{Answer→}}$The work-energy principle is valid regardless of the presence of any non conservative forces. As long as you are using the work done by the resultant force (and resultant moment when involving rigid bodies) in the equation (or equivalently adding the work done by each force/moment), the work energy principle is valid.

Answer 2

The work energy principal is vaild regardless of the presence of any non conservative forces. As long as you are using the work done by the resultant force (and resultant moment when involving rigid bodies) in the equation (or equivlently adding the work done by each force/moment), the work energy principal is vaild.
