1. Energy

   In physics, energy (from Ancient Greek: ἐνέργεια, enérgeia, “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass when stationary (called rest mass) also has an equivalent amount of energy whose form is called rest energy, and any additional energy (of any form) acquired by the object above that rest energy will increase the object's total mass just as it increases its total energy. Human civilization requires energy to function, which it gets from energy resources such as fossil fuels, nuclear fuel, or renewable energy. The Earth's climate and ecosystems processes are driven by the energy the planet receives from the Sun (although a small amount is also contributed by geothermal energy).

1. energy

   Energy is a fundamental concept in physics that refers to the capacity of a system to do work or produce a change. It can exist in different forms, such as kinetic energy (energy of motion), potential energy (stored energy), thermal energy (energy due to temperature), chemical energy (energy stored in chemical bonds), and many others. Energy can be converted from one form to another, but it is never created or destroyed, following the law of conservation of energy.

1. Energy

   In physics, energy is an indirectly observed quantity which comes in many forms, such as kinetic energy, potential energy, radiant energy, and many others; which are listed in this summary article. This is a major topic in science and technology and this article gives an overview of its major aspects, and provides links to the many specific articles about energy in its different forms and contexts. The question "what is energy?" is difficult to answer in a simple, intuitive way, although energy can be rigorously defined in theoretical physics. In the words of Richard Feynman, "It is important to realize that in physics today, we have no knowledge what energy is. We do not have a picture that energy comes in little blobs of a definite amount." However, it is clear that energy is always an indispensable prerequisite for performing mechanical work, and the concept has great importance in natural science. The natural basic units in which energy is measured are those used for mechanical work; they always are equivalent to a unit of force multiplied by a unit of length. Other equivalent units for energy are mass units multiplied by velocity units squared.

1. Energy

   The capacity for doing work. It is measured by work units which involve the exercise of force along a path of some length. A foot-pound, centimeter-gram, and centimeter-dyne are units of energy and work. The absolute unit of energy is the erg, a force of one dyne exercised over one centimeter of space. (See Dyne.) The dimensions of energy are   force (M * L / T^2) * space (L) = M * (L^2 / T^2). Energy may be chemical (atomic or molecular), mechanical, electrical, thermal, physical, potential, kinetic, or actual, and other divisions could be formulated.

Examples of energy in a Sentence

1. Sarah Koenig:

   When you are with Candy, she is energy, she has harnessed that energy and is doing so much with it to inspire others. The energy was always there, sometimes working for her, sometimes against her. But once she cleared the noise and eliminated the self-sabotage, she harnessed that energy and now uses it in ways that truly serve her community, herself, her clients, family, friends. It's a powerful, positive force.

2. H.W. Mann:

   The physical world of matter is a reality. But it is a reality within a larger reality. Matter is made of energy. Everything in the universe is made of energy. We have consciousness. We are consciousness aware of itself. We are pure conscious energy. Energy cannot be created nor destroyed. So, we are immortal pure conscious energy. We have existed before our human incarnation, and we will still exist after. We are immortal pure conscious energy.

3. Jeff Navin:

   Some of the biggest national security questions facing the country run through Piketon and Kemmerer, a Post-Soviet dealAmerican reliance on foreign enriched uranium echoes its competitive disadvantages on microchips and the critical minerals used to make electric batteries — two essential components of the global energy transition.But in the case of uranium enrichment, United States once had an advantage and chose to give it up.In the 1950s, as the nuclear era began in earnest, Piketon became the site of one of two enormous enrichment facilities in the Ohio River Valley region, where a process called gaseous diffusion was used.Meanwhile, the Soviet Union developed centrifuges in a secret program, relying on a team of German physicists and engineers captured toward the end of World War II. Its centrifuges proved to be 20 times as energy efficient as gaseous diffusion. By the end of the Cold War, United States and Russia had roughly equal enrichment capacities, but huge differences in the cost of production.In 1993, Washington and Moscow signed an agreement, dubbed Megatons to Megawatts, in which United States purchased and imported much of Russia’s enormous glut of weapons-grade uranium, which United States then downgraded to use in power plants. This provided the U.S. with cheap fuel and Moscow with cash, and was seen as a de-escalatory gesture.But it also destroyed the profitability of America’s inefficient enrichment facilities, which were eventually shuttered. Then, instead of investing in upgraded centrifuges in United States, successive administrations kept buying from Russia.ImageA mural celebrates Piketon’s gaseous diffusion plant, long ago shuttered, and United States role in the local economy.Credit... Brian Kaiser for The New York TimesImageIn the lobby at Piketon plant, a miniature display of new centrifuges.Credit... Brian Kaiser for The New York TimesThe centrifuge plant in Piketon, operated by Centrus Energy, occupies a corner of the site of the old gaseous diffusion facility. Building United States to United States full potential would create thousands of jobs, according to Centrus Energy. And it could produce the kinds of enriched uranium needed in both current and new-age nuclear plants.Lacking Piketon’s output, plants like TerraPower’s would have to look to foreign producers, like France, that might be a more politically acceptable and reliable supplier than Russia, but would also be more expensive.TerraPower sees itself as integral to phasing out climate-warming fossil fuels in electricity. Its reactor would include a sodium-based battery that would allow the plant to ramp up electricity production on demand, offsetting fluctuations in wind or solar production elsewhere.It is part of the energy transition that coal-country senators like Mr. Manchin and John Barrasso, a Wyoming Republican, are keen to fix as they eye nuclear replacements for lost coal jobs and revenue. While Mr. Manchin in particular has complicated the Biden administration’s efforts to quicken the transition away from fossil fuels, he also pushed back against colleagues, mostly Democrats, who are skeptical of nuclear power’s role in that transition, partly because of the radioactive waste it creates.

4. H.W. Mann:

   Negative programming. We write the programs. And we can rewrite the programs. If we drop the negative self- talk. If we drop the negative self- beliefs. If we drop the negative world view. Then we drop the negative programs. Think about the word negative. It refers to negative energy. What we put our energy into we create more of. Focusing on the negative is like praying for what we don’t want. If we stop putting energy into what we don’t want, then we stop creating it.

5. Ramana Pemmaraju:

   Only when you go beyond Mind, will you be able to respect the energy that inhabits us; until then you will either exploit others with your energy or will deplete your energy, leading a purposeless life!”
