El vector va des del punt de referència fins a la <a href="/wiki/Posici%C3%B3" title="Posició">posició</a> actual. El desplaçament només coincideix amb l'espai recorregut pel <a href="/wiki/M%C3%B2bil_puntual" title="Mòbil puntual">mòbil</a> quan la trajectòria és una <a href="/wiki/L%C3%ADnia_recta" class="mw-redirect" title="Línia recta">línia recta</a>.

El vector desplaçament en l'espai unidimensional coincideix en direcció amb la <a href="/wiki/Traject%C3%B2ria" class="mw-disambig" title="Trajectòria">trajectòria</a> en un <a href="/wiki/Moviment_lineal" class="mw-redirect" title="Moviment lineal">moviment lineal</a>. El vector desplaçament en l'<a href="/wiki/Espai_bidimensional" title="Espai bidimensional">espai bidimensional</a> no coincideix amb la trajectòria, i és la diferència entre els vectors posició r2 i r1. En el moviment en l'espai, el vector desplaçament en l'espai tridimensional tampoc coincidís amb la trajectòria. Té com a origen l'extrem del vector posició r1 i com a extrem el mateix que el vector posició r2. </p><p>Si un mòbil passa d'una posició inicial <span class="mwe-math-element"><span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="display: none;"><math xmlns="http://www.w3.org/1998/Math/MathML" alttext="{\displaystyle \mathbf {r} _{0}}"> <semantics> <mrow class="MJX-TeXAtom-ORD"> <mstyle displaystyle="true" scriptlevel="0"> <msub> <mrow class="MJX-TeXAtom-ORD"> <mi mathvariant="bold">r</mi> </mrow> <mrow class="MJX-TeXAtom-ORD"> <mn>0</mn> </mrow> </msub> </mstyle> </mrow> <annotation encoding="application/x-tex">{\displaystyle \mathbf {r} _{0}}</annotation> </semantics> </math></span><img src="https://wikimedia.org/api/rest_v1/media/math/render/svg/dbe39f0fedae3334af5c4ffaedf25c9778363400" class="mwe-math-fallback-image-inline mw-invert skin-invert" aria-hidden="true" style="vertical-align: -0.671ex; width:2.156ex; height:2.009ex;" alt="{\displaystyle \mathbf {r} _{0}}"></span> a una posició final <span class="mwe-math-element"><span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="display: none;"><math xmlns="http://www.w3.org/1998/Math/MathML" alttext="{\displaystyle \mathbf {r} _{f}}"> <semantics> <mrow class="MJX-TeXAtom-ORD"> <mstyle displaystyle="true" scriptlevel="0"> <msub> <mrow class="MJX-TeXAtom-ORD"> <mi mathvariant="bold">r</mi> </mrow> <mrow class="MJX-TeXAtom-ORD"> <mi>f</mi> </mrow> </msub> </mstyle> </mrow> <annotation encoding="application/x-tex">{\displaystyle \mathbf {r} _{f}}</annotation> </semantics> </math></span><img src="https://wikimedia.org/api/rest_v1/media/math/render/svg/0d2eab65d1af075486a7671fb7ccd987d34473e7" class="mwe-math-fallback-image-inline mw-invert skin-invert" aria-hidden="true" style="vertical-align: -1.005ex; width:2.238ex; height:2.343ex;" alt="{\displaystyle \mathbf {r} _{f}}"></span>, es diu que el mòbil s'ha desplaçat.
