There is no commonly accepted law by that name, as far as I know. Two important laws about energy are the First Law of Thermodynamics and the Second Law of Thermodynamics.
Actually it developed gradually over time. It was not the invention of a single person.
That would be the First Law of Thermodynamics
The concept that energy cannot be created or destroyed is a fundamental principle known as the Law of Conservation of Energy. It is a universal law of physics that applies in all states and is not specific to any particular state's energy laws.
The law applies to everything in the universe.
Energy is conseved. This is the universal law. So nergy cannot be created or destroyed. But energy management is the intelligence with which we utilize the energy maximum to the creative purpose.
No
The universal law of gravitation is given by Issac Newton.
The Law of Universal Gravitation is E= -mGM/r + mcV = m[-u/r, cV ].Gravitation Energy is Quaternion Energy consisting of scalar or Potential energy -mGM/r and vector energy mcV.So-called "Dark Energy" is the vector energy mcV, which is the source of the "Divergent Force", -Divergence of mcV =-mcv/r cos(V)= -ma cos(v).
The law of conservation of mass. It states the total mass of an enclosed system cannot change. The law of conservation of energy. It states that energy can neither be created nor destroyed it transform from one form to another.
Isaac Newton discovered the universal law of gravitation in 1687.
Isaac newton created the universal law of gravitation.
He was in an orchard examining apples falling when he formulated the Universal Law of Gravitation.
