Newton">Isaac Newton</a> formulerade i sitt banbrytande verk <a href="/wiki/Philosophiae_Naturalis_Principia_Mathematica" title="Philosophiae Naturalis Principia Mathematica">Principia</a> 1687. Mekanik är den del av <a href="/wiki/Fysik" title="Fysik">fysiken</a> som beskriver växelverkan mellan materiella system (kroppar) i vila eller rörelse eller, alternativt formulerat, sambandet mellan en kropps rörelse och de <a href="/wiki/Kraft" title="Kraft">krafter</a> som påverkar den. Den klassiska mekanikens giltighetsområde är begränsat dels till kroppar med massor som är mycket större än elementarpartiklarnas massor, dels till kroppar som rör sig med hastigheter som är mycket mindre än ljushastigheten. I annat fall måste hänsyn tas till kvantmekaniska respektive relativistiska effekter. Eftersom klassisk mekanik dels anses som en fundamental vetenskap, dels är av central betydelse inom ett flertal tekniska tillämpningsområden, såsom maskin- och byggnadsteknik, betraktas mekanik ofta som en egen disciplin skild från fysiken. Inom tekniska utbildningar ges ofta separata kurser i mekanik, fristående från allmänna fysikkurser, och ämnet har ofta egna institutioner och akademiska befattningar, till exempel professurer. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Indelning">Indelning</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Klassisk_mekanik&amp;veaction=edit&amp;section=1" title="Redigera avsnitt: Indelning" class="mw-editsection-visualeditor"><span>redigera</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Klassisk_mekanik&amp;action=edit&amp;section=1" title="Redigera avsnitts källkod: Indelning"><span>redigera wikitext</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Klassisk mekanik brukar indelas i <a href="/wiki/Statik" title="Statik">statik</a>, som behandlar kroppar i vila, och <a href="/wiki/Dynamik_(mekanik)" title="Dynamik (mekanik)">dynamik</a>, som behandlar kroppar i rörelse.

En referensram där Newtons lagar gäller brukar benämnas en inertialram (<a href="/wiki/Inertialsystem" title="Inertialsystem">inertialsystem</a>, tröghetssystem). Eftersom krafter i klassisk mekanik förutsätts vara objektiva storheter, det vill säga oberoende av referensram, får en godtagbar referensram inte accelerera. Det är därför brukligt att kräva att en inertialram skall vara fixerad, men eftersom det inte finns någon fix punkt i universum kvarstår likväl problemet. Den enda invändningsfria definitionen är att en inertialram är en referensram, där Newtons första lag är giltig. Dessvärre gäller att det är praktiskt taget omöjligt att genomföra experiment på kroppar utan kraftpåverkan, eftersom detta skulle förutsätta att kroppen avlägsnades på behörigt avstånd från all annan materia. Experiment ger emellertid vid handen att för de flesta praktiska tillämpningar ger en jordfast referensram god överensstämmelse mellan teori och experiment. Dock gäller att i sådana situationer där jordrotationen är av betydelse, till exempel satellitrörelse, vindar och havsströmmar, krävs en referensram som inte medföljer <a href="/wiki/Jorden" title="Jorden">jorden</a> i dess rotation. För studier av planetrörelse krävs en referensram fixerad i förhållande till <a href="/wiki/Solen" title="Solen">solen</a> och så vidare. Slutsatsen är att någon absolut inertialram som är universellt användbar inte kan definieras, men att det för varje enskild tillämpning bör vara möjligt att hitta en referensram där Newtons lagar gäller med tillräckligt god approximation. Även om Newton i Principia inte utvecklade sina tankegångar angående referensramar, har det hävdats att anledningen till att han delade upp sina två första lagar var att han såg den första som ett sätt att fastlägga en giltig referensram. I annat fall hade den första lagen enbart varit ett specialfall av den andra, en beskrivning som ibland framförs i elementära läroböcker. </p><p>Om den första lagen används för att definiera en giltig referensram, kan den andra lagen sägas beskriva hur en kropp rör sig i detta referenssystem då den påverkas av krafter. Här finns skilda meningar om hur begreppet <i>krafter</i> skall tolkas. En uppfattning är att den andra lagen skall ses som en definition av begreppet kraft i termer av massa och acceleration. Det finns åtminstone tre starka invändningar mot detta synsätt. För det första kommer endast summan av de på kroppen verkande krafterna att definieras, även om det är så att kroppen påverkas av ett antal olika krafter med skilda källor. För det andra blir hela definitionen meningslös för en kropp i vila. För det tredje finns det inga möjligheter att göra några som helst förutsägelser om verkligheten med ett sådant synsätt. En mera framkomlig väg skulle kunna vara att låta krafter definieras av andra fysikaliska lagar, det vill säga lagarna för gravitation och elektromagnetism. Detta må vara möjligt att utföra i teorin, men i praktiken är det inte möjligt att utföra kvantitativa beräkningar på detta sätt. I den klassiska mekaniken betraktas därför krafter som ett begrepp, där den kraft som en kropp utövar på en annan definieras från fall till fall beroende på ursprung. Vissa krafter är bestämda av den påverkade kroppens läge och rörelsetillstånd, till exempel gravitationskrafter, elastiska kontaktkrafter, luft- och strömningsmotstånd, och kan beräknas med hjälp av befintliga modeller. Andra krafter uppkommer vid kontakter där en kropp är utsatt för tvång, det vill säga en inskränkning i dess möjlighet att förflytta sig. Sådana krafter benämns tvångskrafter och är i normalfallet obestämda. </p> <div class="mw-heading mw-heading2"><h2 id="Vidareutveckling_av_Newtonsk_mekanik">Vidareutveckling av Newtonsk mekanik</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Klassisk_mekanik&amp;veaction=edit&amp;section=4" title="Redigera avsnitt: Vidareutveckling av Newtonsk mekanik" class="mw-editsection-visualeditor"><span>redigera</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Klassisk_mekanik&amp;action=edit&amp;section=4" title="Redigera avsnitts källkod: Vidareutveckling av Newtonsk mekanik"><span>redigera wikitext</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Den klassiska mekaniken utvecklades vidare under 1700-talet av bland andra <a href="/wiki/Johann_Bernoulli" title="Johann Bernoulli">Johann Bernoulli</a> och <a href="/wiki/Jean_le_Rond_d%27Alembert" title="Jean le Rond d&#39;Alembert">Jean le Rond d'Alembert</a>, som formulerade d'Alemberts princip.
