1. Conservation of energy

   In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law, first proposed and tested by Émilie du Châtelet, means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another. For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes. If one adds up all forms of energy that were released in the explosion, such as the kinetic energy and potential energy of the pieces, as well as heat and sound, one will get the exact decrease of chemical energy in the combustion of the dynamite. Classically, conservation of energy was distinct from conservation of mass. However, special relativity shows that mass is related to energy and vice versa by E = m c 2 {\displaystyle E=mc^{2}} , the equation representing mass–energy equivalence, and science now takes the view that mass-energy as a whole is conserved. Theoretically, this implies that any object with mass can itself be converted to pure energy, and vice versa. However, this is believed to be possible only under the most extreme of physical conditions, such as likely existed in the universe very shortly after the Big Bang or when black holes emit Hawking radiation. Given the stationary-action principle, conservation of energy can be rigorously proven by Noether's theorem as a consequence of continuous time translation symmetry; that is, from the fact that the laws of physics do not change over time. A consequence of the law of conservation of energy is that a perpetual motion machine of the first kind cannot exist; that is to say, no system without an external energy supply can deliver an unlimited amount of energy to its surroundings. Depending on the definition of energy, conservation of energy can arguably be violated by general relativity on the cosmological scale.

1. conservation of energy

   Conservation of energy is a principle in physics that states that the total amount of energy in an isolated system remains constant over time. It implies that energy can neither be created nor destroyed, but can only be transformed or transferred from one form to another. This principle holds true regardless of the specific nature of the energy or the processes occurring within the system.

1. Conservation of energy

   The law of conservation of energy, first formulated in the nineteenth century, is a law of physics. It states that the total amount of energy in an isolated system remains constant over time. The total energy is said to be conserved over time. For an isolated system, this law means energy is localized and can change its location within the system, and it can change form within the system, for instance, chemical energy can become kinetic energy but it can be neither created nor destroyed. Furthermore, two initially isolated systems, that have no external or mutual interaction, can be logically composed into a single isolated system, and then the total amount of energy of the composite system is equal to the sum of the respective total amounts of energy of the two component systems. In this sense, the energy of a system is said to be additive. Likewise, for a homogeneous system in its own internal thermodynamic equilibrium, the internal energy is said to be an extensive quantity. In the twentieth century, the definition of energy was broadened. Material particles, also called ponderable matter, that have rest mass, were recognized as having equivalent amounts of energy. They are not conserved, and can perish into forms of energy, including kinetic and potential energy, that lack rest mass. For example an electron and a positron can perish together into photons of electromagnetic radiation. Likewise, non-material forms of energy can perish into ponderable matter.

1. Conservation of Energy

   the doctrine that, however it may be transformed or dissipated, no fraction of energy is ever lost, that the amount of force, as of matter, in the universe, under all mutation remains the same.

Examples of conservation of energy in a Sentence

1. Solomon Short:

   Nature abhors a hero. For one thing, he violates the law of conservation of energy. For another, how can it be the survival of the fittest when the fittest keeps putting himself in situations where he is most likely to be creamed
