is een meetbare eigenschap van een natuurkundig verschijnsel. Een algemeen geldige korte definitie is niet mogelijk omdat van de vele soorten fysische verschijnselen, <a href="/wiki/Thermische_energie" class="mw-redirect" title="Thermische energie">thermisch</a>, <a href="/wiki/Mechanische_energie" title="Mechanische energie">mechanisch</a>, <a href="/wiki/Stralingsenergie" title="Stralingsenergie">straling</a>, <a href="/wiki/Chemische_energie" title="Chemische energie">chemisch</a>, enz. energie op veel verschillende manieren gemeten wordt. Al deze metingen hebben gemeen dat de resultaten uitgedrukt kunnen worden in dezelfde <a href="/wiki/Natuurkundige_eenheid" title="Natuurkundige eenheid">natuurkundige eenheid</a>. </p><p>De <a href="/wiki/SI-eenheid" class="mw-redirect" title="SI-eenheid">SI-eenheid</a> van energie is de <a href="/wiki/Joule" title="Joule">joule</a>. Omdat alle soorten energie uitgedrukt worden in deze eenheid, zijn ze vergelijkbaar. De warmte die vrijkomt bij verbranding van een ton steenkool bijvoorbeeld, is te vergelijken met de elektriciteit die een windmolen genereert in een bepaalde tijd, hoewel deze hoeveelheden energie zeer verschillend zijn gemeten. </p><p>Energie wordt wel aangeduid als de mogelijkheid om <a href="/wiki/Arbeid_(natuurkunde)" title="Arbeid (natuurkunde)">arbeid</a> te verrichten, of ruimer: de mogelijkheid om een verandering te bewerkstelligen. Energie kan ook gezien worden als essentiële natuurlijke hulpbron, aangezien ze geconsumeerd, geproduceerd en gebruikt wordt door levende wezens, zie <a href="/wiki/Energie_(economie)" title="Energie (economie)">energie (economie)</a>. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Algemeen">Algemeen</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Energie&veaction=edit&section=1" title="Bewerk dit kopje: Algemeen" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Energie&action=edit&section=1" title="De broncode bewerken van de sectie: Algemeen"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>De toename van energie van een mechanisch systeem is de totale hoeveelheid arbeid die moet worden verricht om vanaf een grondtoestand tot de huidige situatie te komen. Bijvoorbeeld hoeveel arbeid het kost om een zwaar voorwerp vanaf de grond op een tafel te zetten, of de hoeveelheid arbeid om een spiraalveer die eerst ontspannen was, een bepaalde afstand in te drukken. </p><p>De totale energie van een systeem is de som van alle vormen van energie die op verschillende manieren zijn opgeslagen. Energie is een <a href="/wiki/Toestandsfunctie" title="Toestandsfunctie">toestandsfunctie</a>, dat wil zeggen: de hoeveelheid energie is onafhankelijk van de voorgeschiedenis. Het maakt bijvoorbeeld niet uit of een veer eerst is ingedrukt en daarna op de tafel is gehesen of andersom. </p><p>Als het systeem niet wordt tegengehouden, zal het altijd proberen de hoeveelheid vrije energie zo klein mogelijk te maken: de veer rolt van tafel af en ontspant zich weer. Als een systeem zich in zo'n toestand van minimale energie bevindt, is het in <a href="/wiki/Evenwicht" title="Evenwicht">evenwicht</a>. </p><p>De totale hoeveelheid energie in een gesloten systeem (dat wil zeggen dat er geen materiaal of straling in- of uit kan) blijft altijd gelijk; dit heet de <i><a href="/wiki/Wet_van_behoud_van_energie" title="Wet van behoud van energie">wet van behoud van energie</a></i>. De totale energie van een systeem is de optelsom van alle microscopische en macroscopische energieën, namelijk; thermische, mechanische, kinetische, potentiële, elektrische, magnetische, chemische en nucleaire energie. De <a href="/wiki/Inwendige_energie" title="Inwendige energie">inwendige energie</a> (U) van een systeem wordt gegeven door de som van alle microscopische energieën; alle bovenstaande behalve kinetische, potentiële en mechanische energie. </p><p>In veel processen wordt een soort energie in een andere omgezet. Zo wordt in een gaskachel de chemische energie in het <a href="/wiki/Gas_(natuurkunde)" class="mw-redirect" title="Gas (natuurkunde)">gas</a> omgezet in <a href="/wiki/Warmte" title="Warmte">warmte</a>. En tijdens het vallen van een voorwerp wordt <i>zwaartekrachtsenergie</i> of <i><a href="/wiki/Potenti%C3%ABle_energie" title="Potentiële energie">potentiële energie</a></i> omgezet in <i>bewegingsenergie</i> of <i><a href="/wiki/Kinetische_energie" title="Kinetische energie">kinetische energie</a></i>. </p><p>Vaak wordt energie verward met <a href="/wiki/Vermogen_(natuurkunde)" title="Vermogen (natuurkunde)">vermogen</a>: dit is echter energie per tijdseenheid. Iemand die op een keukentrapje klimt heeft daarvoor theoretisch net zoveel energie nodig als wanneer hij even hoog springt. Het springen gebeurt in minder tijd en daarom is daarvoor wel meer vermogen nodig. Een beeldend voorbeeld is ook het ophijsen van een piano met een horlogemotor: bij gebruik van een zwak motortje kost het ophijsen van een zwaar voorwerp veel tijd, maar het kan wel (als we wrijving verwaarlozen). </p><p>De intensiteit waarmee een mens diverse vormen van energie ervaart, verschilt soms van de objectief te meten fysische waarde van die energie. Zo is ongeveer 40kJ (40 000 joule) nodig om een kopje water tot tegen het kookpunt te brengen. Met diezelfde hoeveelheid energie zou men een baksteen van een kilogram vanaf het aardoppervlak naar 4 km hoogte kunnen gooien, of een stadsbus van 4 ton een meter optillen (afgezien van omzettings- en wrijvingsverliezen). </p> <div class="mw-heading mw-heading2"><h2 id="Etymologie"><a href="/wiki/Etymologie" title="Etymologie">Etymologie</a></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Energie&veaction=edit&section=2" title="Bewerk dit kopje: Etymologie" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Energie&action=edit&section=2" title="De broncode bewerken van de sectie: Etymologie"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Het woord energie komt van het Griekse ἐνέργεια <i>Energeia</i>, dat waarschijnlijk voor het eerst wordt gebruikt in het werk van <a href="/wiki/Aristoteles" title="Aristoteles">Aristoteles</a> in de 4e eeuw v.
