Kr. </p><p><a href="/wiki/Srednji_vijek" title="Srednji vijek">Srednji vijek</a> je bio razdoblje stvaranja osnova mehanike. S razvojem novih zanata, trgovine, plovidbe i ratnih vještina, i u vezi s tim sakupljenih novih znanja, u 14. i 15. stoljeću (<a href="/wiki/Renesansa" title="Renesansa">renesansa</a>) dolazi do uzleta <a href="/wiki/Znanost" class="mw-redirect" title="Znanost">znanosti</a> i <a href="/wiki/Umjetnost" title="Umjetnost">umjetnosti</a>. Događaj koji je korjenito promijenio dotadašnji pogled na svijet i život je bio rad <a href="/wiki/Nikola_Kopernik" title="Nikola Kopernik">Nikole Kopernika</a> (1473. - 1543.), koji je objavio <a href="/wiki/Heliocentri%C4%8Dni_sustav" class="mw-redirect" title="Heliocentrični sustav">heliocentrični (Kopernikov) sustav svijeta</a>, koji se zasniva na tvrdnjama da se <a href="/wiki/Zemlja" title="Zemlja">Zemlja</a> okreće oko svoje osi i da kruži oko <a href="/wiki/Sunce" title="Sunce">Sunca</a>. Ove tvrdnje su uskoro bile prihvaćene u znanstvenim krugovima. </p><p>Glavna zasluga točnog određivanja osnovnih zakona <a href="/wiki/Klasi%C4%8Dna_mehanika" title="Klasična mehanika">klasične mehanike</a> pripada <a href="/wiki/Isaac_Newton" title="Isaac Newton">Isaacu Newtonu</a> (1643. – 1728.), koji je u djelu <i>Matematička načela prirodne filozofije</i> (u to vrijeme se <a href="/wiki/Fizika" title="Fizika">fizika</a> nazivala prirodnom filozofijom) objavljenom 1687., skupio sva dotadašnja znanja na području mehanike i pokazao put daljnjeg razvoja mehanike za nekoliko stoljeća unaprijed. Newton uvodi pojam <a href="/wiki/Masa" title="Masa">mase</a>, točnije određuje pojam <a href="/wiki/Sila" title="Sila">sile</a> i pomuću svojih <a href="/wiki/Newtonovi_zakoni_gibanja" class="mw-redirect" title="Newtonovi zakoni gibanja">tri Newtonovih zakona gibanja</a> izgrađuje čitavu mehaniku. Newton je otkrio i zakon unutrašnjeg trenja (<a href="/wiki/Viskoznost" title="Viskoznost">viskoznost</a>) u tekućinama i plinovima. Njegovim djelom započinje i novo doba teorijske mehanika. Na osnovu <a href="/wiki/Johannes_Kepler" title="Johannes Kepler">Keplerovih</a> zaključaka o privlačenju među <a href="/wiki/Nebesko_tijelo" title="Nebesko tijelo">nebeskim tijelima</a> i drugih nastojanja u 17. stoljeću, objasnio <a href="/wiki/Newtonov_zakon_gravitacije" title="Newtonov zakon gravitacije">Newtonov zakon gravitacije</a>. Iz njega je matematički izveo Keplerove zakone i to je smatrao dokazom da je pretpostavka izrečena zakonom gravitacije dobro izabrana. Newton je smatrao da taj zakon vrijedi i za mehaniku na <a href="/wiki/Zemlja" title="Zemlja">Zemlji</a>, pa da je uzrok padanja kamena u toj općoj gravitaciji, a da on vrijedi i u nebeskim prostranstvima. Ipak, Newton nije odredio prirodu tog privlačenja (<a href="/wiki/Gravitacija" title="Gravitacija">gravitacije</a>), budući da bi to tražilo da se postavljaju pretpostavke koje ne proizlaze iz pokusa, što je on smatrao nedopustivim. </p><p>Bitna nadogradnja Newtonove klasične mehanike počinje početkom 20. stoljeća, i to u dva smjera: <a href="/wiki/Specijalna_teorija_relativnosti" title="Specijalna teorija relativnosti">specijalna teorija relativnosti</a> <a href="/wiki/Albert_Einstein" title="Albert Einstein">Alberta Einsteina</a> (1905.) i <a href="/wiki/Max_Planck" title="Max Planck">Planckovim</a> otkrićem elementarnog <a href="/wiki/Kvant" title="Kvant">kvanta</a> energije (1900.). Jedna je od bitnih posljedica teorije relativnosti, za razliku od klasične mehanike, da <a href="/wiki/Masa" title="Masa">masa</a> nije konstanta, već je funkcija brzine kojom se tijelo giba i da postoji jednakost između mase i energije, E = m<sub>o</sub> x c<sup>2</sup>, ili da su masa (m) i <a href="/wiki/Energija" title="Energija">energija</a> (E) samo dva oblika kojima se prikazuje <a
