Hi ha diferents tipus de col·lisions, les col·lisions elàstiques, inelàstiques i totalment inelàstiques. Tots aquests xocs tenen la característica de conservar el seu <i>momentum</i> o quantitat de moviment, però no la seva energia mecànica, que en la majoria dels casos només es considera l'energia cinètica. Els xocs que són elàstics mantenen el momentum inicial del sistema igual al final de la mateixa manera que l'energia cinètica total del sistema. Dins d'aquest tipus de xoc és important mencionar un cas importants que és el xoc de dos cossos d'igual massa i un d'ells inicialment en repòs. En el cas que els dos cossos tinguin la mateixa massa i un d'ells es troba en repòs, en impactar es transferirà l'energia des del cos en moviment cap al que no s'està movent, i el cos que es trobava inicialment en moviment romandrà en repòs, mentre que l'altre seguirà en moviment, el mateix que seguia el primer cos, un exemple d'aquest és el joc és el billar. Mentre dura el xoc cal assenyalar que en el contacte dels dos cossos l'energia s'emmagatzema en una deformació mínima i no permanent.</p> <div class="mw-heading mw-heading3"> <h3 id="Col·lisió_elàstica"><span id="Col.C2.B7lisi.C3.B3_el.C3.A0stica"></span>Col·lisió elàstica</h3><span class="mw-editsection"> <a role="button" href="https://ca-m-wikipedia-org.translate.goog/w/index.php?title=Impuls_(f%C3%ADsica)&action=edit&section=3&_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Modifica la secció: Col·lisió elàstica" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> <span class="minerva-icon minerva-icon--edit"></span> <span>modifica</span> </a> </span> </div> <style data-mw-deduplicate="TemplateStyles:r30997230">.mw-parser-output .hatnote{font-style:italic}.mw-parser-output div.hatnote{padding-left:1.6em;margin-bottom:0.5em}.mw-parser-output .hatnote i{font-style:normal}.mw-parser-output .hatnote+link+.hatnote{margin-top:-0.5em}</style> <div role="note" class="hatnote navigation-not-searchable"> Article principal: <a href="https://ca-m-wikipedia-org.translate.goog/wiki/Xoc_el%C3%A0stic?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Xoc elàstic">Xoc elàstic</a> </div> <p>En física, en el cas ideal, una col·lisió perfectament elàstica és un xoc entre dos o més cossos que no pateixen deformacions permanents degut l'impacte.
