    equal amount of energy carried by matter that is moving from one system to another. A turbo generator transforms the energy of pressurized steam into electrical energy. Energy may be transformed between different forms at various efficiencies. Items that transform between these forms are called transducers.

    List of states of matter. Matter organizes into various phases or states of matter depending on its constituents and external factors like pressure and temperature. In common temperatures and pressures, atoms form the three classical states of matter: solid, liquid and gas. Complex molecules can also form various mesophases such as liquid ...

    1 / 3 ⁠. A quark (/ kwɔːrk, kwɑːrk /) is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei. [1] All commonly observable matter is composed of up quarks, down quarks and electrons.

    The graviton must be a spin-2 boson because the source of gravitation is the stress–energy tensor, a second-order tensor (compared with electromagnetism's spin-1 photon, the source of which is the four-current, a first-order tensor). Additionally, it can be shown that any massless spin-2 field would give rise to a force indistinguishable from ...

    en.wikipedia.org/wiki/History_of_energy

    The product of the mass of a body into the square of its velocity may properly be termed its energy. [4] Gustave-Gaspard Coriolis described "kinetic energy" in 1829 in its modern sense, and in 1853, William Rankine coined the term " potential energy." It was argued for some years whether energy was a substance (the caloric) or merely a physical ...

    Magnetism. The most useful and widely employed application of magnetism is in the production of electrical energy. The mechanical power needed to assist in this production is provided by a number of different sources. These sources are called prime movers, and include diesel, petrol and natural gas engines. Coal, oil, natural gas, biomass and ...
