Examples
The total Energy ($E$) corresponds to the sum of the total Kinetic Energy ($K$) and the potential Energy ($V$):
| $ E = K + V $ |
(ID 3687)
When we have friction, we observe that bodies heat up, which makes sense to discuss thermal energy. In these cases, the total energy
| $ E = K + V $ |
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
| $ E = K + U + Q $ |
and there are only conversions between these.
