What you learn in Theory:
Law of conservation of energy states that the total amount of energy in an isolated system remains constant over time.
What you learn in Practice:
The principle of conservation of energy states that energy cannot be created or destroyed, i.e. in an isolated system, the total energy before transformation is equal to the total energy transformation.
