The principle of conservation of energy is represented by________.
The principle of energy conservation
It states that energy is neither created nor destroyed. It may transform from one form to another. Similar to the mass conservation principle, the validity of the conservation of energy relies on experimental observations; thus, it is an empirical law.
Equation for representation
For conservative forces, the total mechanical energy (= potential energy + kinetic energy) is constant.
This equation shows that the total mechanical energy of the system remains constant when the internal force is conservative and the external force does not work.
Hence, the principle of conservation of energy is represented by, for conservative forces, the total mechanical energy (= potential energy + kinetic energy) is constant.
