Conservation of mechanical energy: The Law of conservation of mechanical energy states that in a closed-loop system, the kinetic energy may convert into potential energy, or potential energy may convert into kinetic energy in the absence of forces (like f...
More generally, the total potential energy is the sum of all the potential energies possible in a given situation. There is no new physics in the principle of conservation of mechanical energy. Everything follows from Newton's laws (refer back to the introduction of kinetic energy and potential...
In most thermodynamic problems, the principle of energy conservation applied to nonreactive systems accounts for thermal and mechanical energies.

Energy comes in various forms and can be converted between each other provided the law of conservation of energy is always obeyed. In chemical reactions, the energy released or absorbed is associated with a small change in mass of the reacting species, and hence we ne...
The derivation is obtained within the framework of the continuum mechanics and classical thermodynamics. The adopted procedure provides the conservation equations of mass, momentum, mechanical energy, total energy, internal energy, entropy, temperature, enthalpy, Gibbs free energy and Helmholtz free energy...
