The laws of energy are defined by the three laws of thermodynamics, Einstein’s theories of relativity, and Newton’s laws of motion. Energy cannot be created or destroyed, but can be transformed into other forms. Einstein’s formula E=MC2 showed that matter and energy are interchangeable. The second law of thermodynamics explains the principle of entropy, where energy becomes less available for further work. The third law states that zero energy cannot exist. These laws have made modern technologies possible, such as nuclear power and medical equipment like MRI machines.
The laws of energy governing the interactions of matter and energy, such as the transfer of heat from one body to another in the physical universe, are most fundamentally defined by the three laws of thermodynamics and Albert Einstein’s discovery of his theories of special and general relativity. Physics itself is built on these laws, as well as on the three fundamental laws of motion defined by Isaac Newton and first published in 1687, which explain the interaction of all matter. The field of quantum mechanics that began to emerge in the early 20th century also clarified special circumstances for the subatomic-scale energy laws, on which much of modern civilization is based since the 20th century.
One of the fundamental principles of the laws of energy elucidated by the first law of thermodynamics is that energy is neither created nor destroyed. All forms of energy such as light or sound energy can be transformed into other forms, and this was first revealed in the mid-1800s by the work of James Joule, a pioneering English physicist, after whom the unit of basis of energy, the joule, has been named. After ten years of pondering the nature of the relationship between matter and energy, Albert Einstein published his famous formula for E=MC2 in 1905, which stated that both matter and energy were versions of the same thing and could be transformed into each other. in the other as well. Since the equation states that energy (E) equals mass (M) times the speed of light squared (C2), it was actually stating that, if you had enough energy, you could convert it to mass, and if you accelerate enough mass, you could convert it into energy.
The second law of thermodynamics defined the laws of energy by stating that, in any activity where energy was used, its potential decreased or became less and less available for further work. This reflected the principle of entropy and explained where energy went when heat or light escaped into its surroundings, which had baffled mankind for centuries. Entropy is the idea that high levels of concentrated energy, such as that in fuel before it is burned, eventually leaks out into space as waste heat and cannot be recovered. It was in harmony with the first law of thermodynamics because energy was not destroyed, but access to it was lost.
The third law of thermodynamics was clarified in 1906 by research conducted by Walther Nernst, a German chemist. He revealed that it was impossible to create a region of space or matter in which zero energy existed, which would cool the region to the lowest possible temperature of absolute zero. This supported the first and second laws of thermodynamics in that energy would always be available in space or matter to some degree, even if it could not be harnessed for useful work.
Einstein’s updates on our understanding of the laws of energy made many modern technologies possible, such as nuclear power. In addition, Newton’s laws of motion have shown scientists and engineers how to harness the relationship between matter and energy to generate the force and trajectory needed to put satellites into orbit or send space probes to nearby planets. Quantum mechanics has contributed to the understanding of how energy is used and transferred to create technologies such as lasers, transistors which underpin all computer systems, and advanced medical equipment such as magnetic resonance imaging (MRI).
