Energy is delta PEg and kinetic energy Delta KE of a fluid.
Delta KE= (1/2)(gv)V1^2 -(1/2)(gv)v2^2
Heating water Cp = 1 cal/ g K
The First Law of Thermodynamics - or Law of Energy Conservation - can't be attributed to a single person. It developed gradually over time; initially, the conversion of specific types of energy was known, gradually more and more types of energy were added.Nowadays, it is commonly derived from Nöther's Theorem - a theorem created by Emily Nöther.
Newton's third law of motion - simplified into the sentence, "To every action there is an equal and opposite reaction."
Noether's theorem states that for every symmetry in a physical system, there is a corresponding conservation law. In the case of energy conservation, the theorem shows that the symmetry of time translation (the laws of physics remain the same over time) leads to the conservation of energy. This means that energy cannot be created or destroyed, only transformed from one form to another.
Then the laws of physics would change over time. Read about Noether's Theorem for more details.
The "why" is somewhat tricky to answer; the law of conservation of energy was originally based on observation. Nowadays, if you read about the conservation of energy, it is derived from Noether's Theorem. This is some very advanced math, but briefly, it states that every conservation law is related to a symmetry in nature. In the case of conservation of energy, it is related to the fact that laws of physics don't change over time. In other words, according to this theorem, if energy were NOT conserved, then the laws of nature would change over time! However, the details are some very advanced math. You can read the Wikipedia article on Noether's Theorem if you think you can handle it - or if you just want a brief introduction.The "why" is somewhat tricky to answer; the law of conservation of energy was originally based on observation.

You can't create energy out of nothing (First Law of Thermodynamics); this is an experimentally established fact (i.e., no exceptions are known). Nowadays, the law of conservation of energy (or First Law of Thermodynamics) is often derived from Noether's Theorem, but that is some advanced math.You can convert one type of energy to another, but see also the Second Law of Thermodynamics.You can't create energy out of nothing (First Law of Thermodynamics); this is an experimentally established fact (i.e., no exceptions are known).

Because, this theorem comes from the law of sines which is completely a triangle law and the law of sines can not be applied on other polygons.
Nowadays it is demonstrated by Noether's Theorem. Note that this involves some fairly advanced math. The basic assumption (for the Theorem) is that the laws of physics don't change over time. Another kind of reasoning is by observation: in all known processes, energy is always conserved.
The developer of the Coase theorem was a gentleman called Ronald Coase. Coase theorem is used in the subject area of law and economics as stated on reference websites.
energy. This law states that energy cannot be created or destroyed, only transferred or transformed. The rule ensures that energy is conserved in a closed system.
If energy were not conserved, it would mean that energy could seemingly appear out of nowhere or disappear without a trace, violating one of the fundamental principles in physics. This would have significant implications for our understanding of the universe and the way it operates.
