Podle druhého Newtonova zákona (<a href="/wiki/Z%C3%A1kon_s%C3%ADly" class="mw-redirect" title="Zákon síly">zákon síly</a>) musí být toto zrychlení způsobeno silou, kterou nějaké jiné těleso B působí na těleso A. Tato <a href="/wiki/S%C3%ADla" title="Síla">síla</a> má stejný směr jako <a href="/wiki/Zrychlen%C3%AD" title="Zrychlení">zrychlení</a>, to znamená do středu, a proto se nazývá dostředivou silou. Podle třetího Newtonova zákona (<a href="/wiki/Z%C3%A1kon_akce_a_reakce" class="mw-redirect" title="Zákon akce a reakce">akce a reakce</a>) musí také těleso A působit stejně velkou silou na těleso B, ale opačným směrem. To znamená, že tato reakce má směr od středu otáčení a lze ji označovat jako odstředivou sílu. </p><p>Příklad: <a href="/wiki/Pr%C5%AFjezd_obloukem" title="Průjezd obloukem">průjezd obloukem</a>. Aby <a href="/wiki/%C5%BDelezni%C4%8Dn%C3%AD_v%C5%AFz" title="Železniční vůz">železniční vůz</a> projel levým obloukem a nepokračoval v pohybu přímým směrem (<a href="/wiki/Z%C3%A1kon_setrva%C4%8Dnosti" class="mw-redirect" title="Zákon setrvačnosti">zákon setrvačnosti</a>), musí na něj působit síla směrem doleva. Na železnici tuto dostředivou sílu zajišťuje kolej a můžeme ji nazvat akcí. Zároveň s ní vzniká reakce, takže vůz působí na kolej stejně velkou silou, ale směrem doprava. Kdyby nebyla kolej dobře uložena, tato síla by s ní pohnula (což se občas i stane, zejména při spolupůsobení pnutí v extrémních vedrech). Míří směrem od středu oblouku, takže jí můžeme říkat odstředivá síla. Je to síla skutečná, ale působí na kolej, nikoli na jedoucí vůz. Nemá tedy význam sčítat ji se silami působícími na vůz. Situaci jsme popsali v inerciální vztažné soustavě spjaté se Zemí. V této soustavě není žádná odstředivá síla, která by působila na vůz. </p><p>Velikost odstředivé síly <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 F_{\mathrm {o} }}"> <semantics> <mrow class="MJX-TeXAtom-ORD"> <mstyle displaystyle="true" scriptlevel="0"> <msub> <mi>F</mi> <mrow class="MJX-TeXAtom-ORD"> <mrow class="MJX-TeXAtom-ORD"> <mi mathvariant="normal">o</mi> </mrow> </mrow> </msub> </mstyle> </mrow> <annotation encoding="application/x-tex">{\displaystyle F_{\mathrm {o} }}</annotation> </semantics> </math></span><img src="https://wikimedia.org/api/rest_v1/media/math/render/svg/b4b00b74b53e707e08253fa4fa2857b0a9d8b3f2" class="mwe-math-fallback-image-inline mw-invert skin-invert" aria-hidden="true" style="vertical-align: -0.671ex; width:2.549ex; height:2.509ex;" alt="{\displaystyle F_{\mathrm {o} }}" /></span> působící na kolej je stejná jako velikost <a href="/wiki/Dost%C5%99ediv%C3%A1_s%C3%ADla" title="Dostředivá síla">dostředivé síly</a> <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 F_{\mathrm {d} }}"> <semantics> <mrow class="MJX-TeXAtom-ORD"> <mstyle displaystyle="true" scriptlevel="0"> <msub> <mi>F</mi> <mrow class="MJX-TeXAtom-ORD"> <mrow class="MJX-TeXAtom-ORD"> <mi mathvariant="normal">d</mi> </mrow> </mrow> </msub> </mstyle> </mrow> <annotation encoding="application/x-tex">{\displaystyle F_{\mathrm {d} }}</annotation> </semantics> </math></span><img src="https://wikimedia.org/api/rest_v1/media/math/render/svg/94c70082e398a95e8d658918edea80a198a2351d" class="mwe-math-fallback-image-inline mw-invert skin-invert" aria-hidden="true" style="vertical-align: -0.671ex; width:2.641ex; height:2.509ex;" alt="{\displaystyle F_{\mathrm {d} }}" /></span>, kterou působí kolej na vůz.
