Vrijeme omogućuje razlikovanje dvaju inače potpuno istih događaja u istoj točki <a href="/wiki/Prostor" title="Prostor">prostora</a>. Razmak (<a href="/wiki/Udaljenost" class="mw-redirect" title="Udaljenost">udaljenost</a>) između tih događaja služi kao osnova za <a href="/wiki/Mjerenje" title="Mjerenje">mjerenje</a> vremena. Događanje, promjena i <a href="/wiki/Gibanje" title="Gibanje">gibanje</a> ne mogu se shvatiti bez vremena. Vrijeme se može uočiti samo po promjeni događanja. Mnoge se <a href="/wiki/Pojava" title="Pojava">pojave</a> u <a href="/wiki/Priroda" title="Priroda">prirodi</a> pravilno ponavljaju i mogu poslužiti za određivanje vremena. Tako se na primjer <a href="/wiki/Zemljina_rotacija" title="Zemljina rotacija">Zemljinom vrtnjom</a> oko njezine <a href="/wiki/Os" title="Os">osi</a> određuje vrijeme od jednoga <a href="/wiki/Dan" title="Dan">dana</a>, a njezinim <a href="/wiki/Zemljina_putanja" title="Zemljina putanja">gibanjem oko Sunca</a> vrijeme od jedne <a href="/wiki/Godina" title="Godina">godine</a>. Na načelu <a href="/wiki/Njihalo" title="Njihalo">njihala</a> konstruirana je <a href="/wiki/Sat_(instrument)" title="Sat (instrument)">ura njihalica</a>. Za određivanje vremena služe i druge naprave, na primjer <a href="/wiki/Pje%C5%A1%C4%8Dani_sat" title="Pješčani sat">pješčani sat</a>, <a href="/wiki/Vodeni_sat" title="Vodeni sat">vodeni sat</a>, mehanički sat, <a href="/wiki/Digitalizacija" title="Digitalizacija">digitalni</a> sat, <a href="/wiki/Atomski_sat" title="Atomski sat">atomski sat</a> i drugo.

Prema jednome (koje odgovara na primjer <a href="/wiki/Isaac_Newton" title="Isaac Newton">Newtonovim</a> predodžbama), vrijeme je dio stvarne i fundamentalne strukture <a href="/wiki/Svemir" title="Svemir">svemira</a>: ono je <a href="/wiki/Dimenzija" title="Dimenzija">dimenzija</a> svemira u kojoj se događaji odvijaju nekim redoslijedom - i nije ovisno o tim događajima. Prema drugom stajalištu (koje uglavnom odgovara <a href="/wiki/Gottfried_Leibniz" title="Gottfried Leibniz">Leibnizovim</a> i <a href="/wiki/Immanuel_Kant" title="Immanuel Kant">Kantovim</a> nazorima), vrijeme je samo dio čovjekovog intelektualnog aparata, način na koji ljudska svijest percipira i tumači događaje. U fizikalnim razmatranjima prirode vremena dominira prvo stajalište (premda ima i pokušaja alternativnih tumačenja). Vrijeme je fundamentalna dimenzija svemira, duž koje su događaji poredani od prošlosti prema budućnosti. Pomoću vremena se mjeri "gdje" se u tome poretku događaj nalazi (kada, to jest u kojem <i>trenutku</i> se zbiva), te koliki su razmaci između događaja ili trajanje procesa (koliko su "dugački" <i>vremenski intervali</i>). Usto, razvoj fizike u <a href="/wiki/Albert_Einstein" title="Albert Einstein">Einsteinovo</a> doba je pokazao kako opažanja trenutaka i intervala mogu ovisiti o promatraču koji ih mjeri. </p><p><a href="/wiki/Isaac_Newton" title="Isaac Newton">Isaac Newton</a> je smatrao da je vrijeme "apsolutno", to jest da teče jednako za sve promatrače. <a href="/wiki/Klasi%C4%8Dna_mehanika" title="Klasična mehanika">Klasična mehanika</a> (preciznije, <i>nerelativistička klasična mehanika</i>) je utemeljena na Newtonovom konceptu vremena. Da bi protumačio neka opažanja s kraja 19. stoljeća, <a href="/wiki/Albert_Einstein" title="Albert Einstein">Albert Einstein</a> je u svojoj specijalnoj <a href="/wiki/Teorija_relativnosti" title="Teorija relativnosti">teoriji relativnosti</a> postulirao jednakost iznosa <a href="/wiki/Brzina_svjetlosti" title="Brzina svjetlosti">brzine svjetlosti</a> (u <a href="/wiki/Vakuum" title="Vakuum">vakuumu</a>) za sve promatrače, te pokazao da zbog toga oni neće na isti način opažati prostor i vrijeme. Mjerenja prostora i vremena postaju zbog toga međuovisna, zbog čega se u fiziku uvodi koncept četverodimenzionalnog prostorno-vremenskog kontinuuma (<a href="/wiki/Prostorvrijeme" title="Prostorvrijeme">prostorvrijeme</a>). </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Trenutak_i_vremenski_interval">Trenutak i vremenski interval</h2></div> <p>Za operativno korištenje koncepta vremena u fizici (jednako u klasičnoj i relativističkoj) i u drugim znanostima i primjenama, nužno je jasno razlikovati pojam "trenutak" od pojma "vremenski interval". U svakodnevnom govoru, termin "vrijeme" (u gore navedenome <a href="/wiki/Fizika" title="Fizika">fizikalnom smislu</a>) često se koristi tako kao da ta razlika ne postoji. </p> <div class="mw-heading mw-heading3"><h3 id="Trenutak">Trenutak</h3></div> <p><b>Trenutak</b> se označava simbolom <i>t</i> i često se opisuje kao "točka u vremenu". Taj se opis temelji na analogiji s prostornom dimenzijom koju opisujemo na primjer pomoću koordinatne osi "x" <a href="/wiki/Kartezijev_koordinatni_sustav" title="Kartezijev koordinatni sustav">Kartezijevog sustava</a>. Kao što <i>x</i> predstavlja položaj ili koordinatu ("točku u prostoru") na toj osi, tako je <i>t</i> koordinata ili "točka" duž analogne koordinatne osi "t". Na toj se analogiji temelji grafički prikaz (pa i razumijevanje) veličina koje su "funkcije vremena". </p><p>Jednostavnije je, međutim, objasniti pojam trenutka pomoću uređaja za mjerenje vremena, kao što je sat na slici desno. Trenutak je ono što upravo pokazuje taj sat, to jest 6 <a href="/wiki/Sat" title="Sat">sati</a> i 8 <a href="/wiki/Minuta" title="Minuta">minuta</a> (približno). </p><p>Jasno je da "sadašnji" trenutak ovisi o tome kada je bio "početni trenutak" <i>t = 0</i> (na takvome satu početni trenutak je u 12 sati). Još bolji primjer je zaporna ura ("štoperica"). Kod nje biramo početni trenutak <i>t = 0</i> (to jest "ishodište za mjerenje vremena") kada je aktiviramo. Svaka brojka koju nakon toga pokaže kazaljka (ili se ispiše na ekranu) je "tadašnji" trenutak <i>t</i>. </p><p>Tako pojedini trenutak <i>t</i>, iako sam nema trajanja, pokazuje koliko je vremena proteklo od odabranog (dogovorenog) početnog trenutka <i>t = 0</i>. Naravno, vrijeme je postojalo i prije takvoga proizvoljno odabranoga početnog trenutka, kao što je uključivanje zaporne ure. Ti raniji trenutci opisuju se negativnim brojevima, na primjer trenutak <i>t = -3s</i> zbio se 3 sekunde prije trenutka <i>t = 0</i>. U povijesnom opisu vremena pomoću <a href="/wiki/Gregorijanski_kalendar" title="Gregorijanski kalendar">Gregorijanskog kalendara</a>, umjesto "negativnih" godina koristi se oznaka <i>prije Krista</i> ili <i>prije nove ere</i>. </p><p>"Apsolutni" svemirski početni trenutak <i>t = 0</i>, prema fizikalnoj teoriji <a href="/wiki/Veliki_prasak" title="Veliki prasak">Velikog praska</a> i s njom povezanim mjerenjima <sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> desio se prije približno 13,75 milijardi godina. Tada, grubo govoreći, zajedno sa svemirom nastaje i prostor i vrijeme, te nema ranijih ("negativnih") trenutaka. </p> <div class="mw-heading mw-heading3"><h3 id="Vremenski_interval">Vremenski interval</h3></div> <p><b>Vremenski interval</b> opisuje koliko je vremena proteklo između neka dva trenutka.

Zvjezdano vrijeme potrebno je da bi se odredio položaj zvijezda, a osim u <a href="/wiki/Astronomija" title="Astronomija">astronomiji</a>, primjenjuje se u <a href="/wiki/Geodezija" title="Geodezija">geodeziji</a> i <a href="/wiki/Navigacija" title="Navigacija">navigaciji</a>. <sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading4"><h4 id="Zvjezdano_vrijeme">Zvjezdano vrijeme</h4></div> <p>Kazaljka zvjezdanog vremena je <a href="/wiki/Proljetna_to%C4%8Dka" title="Proljetna točka">proljetna točka</a>. Zvjezdano vrijeme jednako je satnom kutu proljetne točke. Zvjezdani dan počinje kada se proljetna točka nalazi u gornjoj kulminaciji. Zvjezdano vrijeme povezano je u svakom času sa satnim kutom i <a href="/wiki/Rektascenzija" title="Rektascenzija">rektascenzijom</a> zvijezde. Ono je ograničeno time na razdoblje od 0 do 24 h. Zvjezdano vrijeme teče onoliko jednoliko koliko se jednoliko <a href="/wiki/Zemljina_rotacija" title="Zemljina rotacija">Zemlja okreće</a>. Tok zvjezdanog vremena određen je samo Zemljinom vrtnjom u odnosu na zvijezde. U toku vremena postoje male promjene. Razlozi tih promjena trojaki su. Jedan je učinak <a href="/wiki/Morske_mijene" title="Morske mijene">plime</a>. Pri gibanju plimnih valova dolazi do <a href="/wiki/Trenje" title="Trenje">trenja</a> između <a href="/wiki/More" title="More">vodenih masa</a> i dna. Trenjem se gubi dio <a href="/wiki/Kineti%C4%8Dka_energija" title="Kinetička energija">kinetičke energije</a> vrtnje pa se ona usporava. Pojava se očituje u stoljetnim razmacima. Zatim, postoje sezonske promjene brzine vrtnje jer se ovisno o <a href="/wiki/Godi%C5%A1nja_doba" title="Godišnja doba">godišnjem dobu</a> mijenjaju jačine i smjerovi <a href="/wiki/Vjetar" title="Vjetar">vjetrova</a> te <a href="/wiki/Morska_struja" title="Morska struja">morskih struja</a>. Stoga se vrtnja i usporava i ubrzava u toku godine, ovisno o tome pomažu li strujanja Zemljinoj vrtnji ili odmažu. Treći razlog krije se u gibanjima u <a href="/wiki/Zemljina_jezgra" title="Zemljina jezgra">Zemljinoj unutrašnjosti</a> i u fizičkom prostoru Zemljine okoline. </p><p>Sunčev dan zadan je ne samo Zemljinom vrtnjom oko vlastite osi, već i <a href="/wiki/Zemljina_putanja" title="Zemljina putanja">Zemljinom godišnjom putanjom</a> oko Sunca. Pritom Zemlja učini jedan okret više oko svoje osi, s obzirom na proljetnu točku (ili zvijezde) nego s obzirom na Sunce. Obilaženje oko Sunca čini jedan dodatni okret Zemlje prema sustavu zvijezda. To znači da će broj zvjezdanih dana u Sunčevoj (tropskoj) godini biti za jedinicu veći od broja Sunčevih dana u Sunčevoj godini: </p> <dl><dd><b>(<i>T</i> + 1) zvjezdani dan = <i>T</i> Sunčev dan</b></dd></dl> <p>gdje je <i>T</i> - <a href="/wiki/Tropska_godina" title="Tropska godina">Sunčeva ili tropska godina</a> koja iznosi 365 d 5 h 48 min 46 s = 365,24219 d, pa dobivamo : </p> <dl><dd>1 zvjezdani dan = 23 h 56 min 4 s</dd></dl> <p>Zvjezdani dan dijeli se sam po sebi u 24h zvjezdanog vremena, a sati, minute i sekunde zvjezdanog vremena takoder traju krace od sata, minuta i sekundi Sunčeva vremena: </p> <dl><dd>1 zvjezdani sat = 59 min 50 s</dd> <dd>1 zvjezdana minuta = 59,8 s</dd></dl> <p>Zvjezdano vrijeme ovisi o tome u kojem se godišnjem dobu nalazimo. Onog časa kada je Sunce u proljetnoj točki s kojom zajedno prolazi kroz gornju kulminaciju podne je (12 h Sunčeva vremena), no istodobno je i početak zvjezdanog dana (0 h zvjezdanog vremena). Narednog će se dana Sunce naći istočnije od proljetne točke jer ono među zvijezdama odmiče na <a href="/wiki/Istok" title="Istok">istok</a>, pa će u dnevnoj vrtnji neba "zaostajati" za zvijezdama i kasnije proći nego proljetna točka. Kada <a href="/wiki/Kut" title="Kut">kut</a> između satnog kruga proljetne točke i Sunca poraste na 90° (<a href="/wiki/Suncostaj" title="Suncostaj">početak ljeta</a>), zvjezdano će vrijeme biti "mlađe" od Sunčeva za 6 h; kada poraste na 180° (početak <a href="/wiki/Jesen" title="Jesen">jeseni</a>), zvjezdano vrijeme jednako je Sunčevom; kada razlika dosegne 270° (početak <a href="/wiki/Zima" title="Zima">zime</a>), zvjezdano će vrijeme biti za 6 h "starije" od Sunčevog. </p> <div class="mw-heading mw-heading4"><h4 id="Srednji_Sunčev_dan"><span id="Srednji_Sun.C4.8Dev_dan"></span>Srednji Sunčev dan</h4></div> <p>Sunce se ne giba jednolikom brzinom po ekliptici, a <a href="/wiki/Ekliptika" title="Ekliptika">ekliptika</a> se ne podudara s <a href="/wiki/Nebeski_ekvator" title="Nebeski ekvator">nebeskim ekvatorom</a>. Po ekliptici se Sunce ne giba jednoliko jer njegovo prividno gibanje samo odražava pravo gibanje Zemlje oko Sunca; Zemlja se po ekliptičnoj stazi giba promjenjivom <a href="/wiki/Brzina" title="Brzina">brzinom</a>. Stoga Sunce ne prelazi svakog dana jednake kutove po ekliptici. Sunce isto mijenja svoju kutnu udaljenost od nebeskog ekvatora. To znači da ono osim gibanja usporedo s nebeskim ekvatorom izvodi još i gibanje u smjeru okomitom na <a href="/wiki/Ekvator" title="Ekvator">ekvator</a>. Na primjer, dan poslije početka <a href="/wiki/Prolje%C4%87e" title="Proljeće">proljeća</a>, Sunce će se naći nešto sjevernije od nebeskog ekvatora. Dnevni pomaci na sjever ili na jug od nebeskog ekvatora najveći su u doba <a href="/wiki/Ravnodnevnica" class="mw-redirect" title="Ravnodnevnica">ravnodnevnica</a>, a u doba oko <a href="/wiki/Suncostaj" title="Suncostaj">suncostaja</a> Sunce se giba usporedo s nebeskim ekvatorom. To znači, i kada bi se Sunce ekliptikom i gibalo ravnomjerno, njegova se projekcija na nebeski ekvator ne bi gibala ravnomjerno. </p><p>Pravi Sunčevi dani ne traju zato jednako. <b>Srednji Sunčev dan</b> (ili naprosto <a href="/wiki/Dan" title="Dan">dan</a>) je prosjek svih pravih Sunčevih dana u toku tropske ili Sunčeve godine. Danas se trajanje srednjeg Sunčevog dana prati pomoću <a href="/wiki/Atomski_sat" title="Atomski sat">atomskih satova</a>. Godine 1967. dogovoreno je da se umjesto sekunde određene iz gibanja Zemlje, kao jedinica vremena iskoristi atomska sekunda ili sekunda određena atomskim satom. Ta je sekunda povezana s trajanjem tropske ili Sunčeve godine 1900. Sekundom se smatra razdoblje vremena koji je bio 31 556 925,9747 puta sadržan u toj tropskoj godini. Kako se duljina dana i tropske godine s vremenom mijenjaju, to se radi usklađenja vremena dana s kalendarom ubacuje u <a href="/wiki/Kalendar" title="Kalendar">kalendarski</a> dan dodatna (prekobrojna) <a href="/wiki/Sekunda" title="Sekunda">sekunda</a>. </p> <div class="mw-heading mw-heading4"><h4 id="Jednadžba_vremena"><span id="Jednad.C5.BEba_vremena"></span>Jednadžba vremena</h4></div> <p>Prirodne pojave, kao što su izlazak i zalazak Sunca, te gornja <a href="/wiki/Kulminacija" title="Kulminacija">kulminacija</a> (pravo mjesno podne), ovise o gibanju pravog Sunca.
