Mechanical Energy and its Conservation

The change in total mechanical energy is the work done by non-conservative forces.
In case there aren’t any (no friction, etc.):

W(nc) = change in KE + change in PE


The total mechanical energy doesn’t change. It is
conserved in the absence of non-conservative forces.

W(nc) = change in KE + change in PE
