10.6: Conservation of Energy
Conservation of Energy. The mechanical energy E of a particle stays constant unless forces outside the system or non-conservative forces do work on it, in which case, the change in the mechanical energy is equal to the work done by the non-conservative forces: Wnc,AB = Δ(K + U)AB = ΔEAB.
