First of all, it stems from a large number of observations. No violation of the law of conservation of energy has been found, despite the fact that thousands of scientists have dedicate many years to study energy-related phenomena.
Currently, however, the law of conservation of energy is usually derived to Noether's Theorem, which relates conservation laws with symmetry laws. In the case of conservation of energy, according to Emmy Nöther, this is related to the fact that physical laws are the same today as they were yesterday. In other words, if conservation of energy would be violated, that would be equivalent to physical laws changing over time! Since this involves some pretty advanced math which I don't understand, and you probably don't understand either, I won't go into details; but if you are interested in the details, read the encyclopedia article on Noether's Theorem.
The Law of Conservation of Energy was not invented, or discovered, by a single person. Rather, it was developed gradually over time, for example, as more forms of energy were recognized to be interchangeable.
James Joules created the law of conservation of energy.
It means that a quantity, called "energy", can be defined, that will neither increase nor decrease over time.
look up the experiments done by James joule
no matter what year we all use it
ssssss
Law of conservation of energy. Energy can't be created or destroyed is the basic statement of the law of conservation of energy.
The law of Conservation of Energy. Actually, that law has been superceded now by a slightly different one. Recently (maybe 100 years ago) it was learned that energy can become mass and mass can become energy. So the law had to be modified to say that the total combination of mass and energy can't be created or destroyed.
Law of Conservation of energy
Scientists call this law the law of conservation of matter
That law is known as the Law of Conservation of Energy. It is also known as the First Law of Thermodynamics.
a matter that cant be created or destroyed. it can change form but have a fixed volume.
law of coservation states that mass can neither be created nor be destroyed in a chemical reaction. Morover, it tells that the total mass of reactants is equal to the total mass of products....
coservation helps keep steam that we have used stored

The law is: Energy can not be created, nor destroyed.
