Conservation of Mechanical Energy
... Conservation of Mechanical Energy I. Introduction A. In the absence of dissipative forces (i.e. non-conservative forces that do work, such as kinetic friction), the mechanical energy of an isolated system is conserved. This can be written in the form: Kf + Uf = Ki + Ui. Thus the sum of the kineti ...
