The total Energy ($E$) corresponds to the sum of the total Kinetic Energy ($K$) and the potential Energy ($V$):
When we have friction, we observe that bodies heat up, which makes sense to discuss thermal energy. In these cases, the total energy
doesn't seem to be conserved unless we interpret the generated heat as another form of energy. Mohr was the first to realize that the sum of kinetic energy $K$, potential energy $V$, and thermal energy $Q$ is conserved
and there are only conversions between these.
