| Also Known As | Energy conservation law, first law of thermodynamics (energy form), conservation of energy principle |
What is Law of Conservation of Energy?
The Law of Conservation of Energy states that energy cannot be created or destroyed, only converted from one form to another. The total energy of an isolated system remains constant. This is equivalent to the First Law of Thermodynamics. All forms of energy (kinetic, potential, thermal, chemical, nuclear, electromagnetic) are interconvertible while the total remains constant.
