una bilancia a contrappeso, invece, restituirà lo stesso valore, in quanto si basa sul confronto di masse (ciò vuol dire che anche su pianeti diversi uno stesso corpo mantiene la sua massa, mentre la forza peso varia in base all'accelerazione di gravità). </p> <div class="mw-heading mw-heading2"><h2 id="Approssimazione_della_forza_peso">Approssimazione della forza peso</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Forza_peso&amp;veaction=edit&amp;section=2" title="Modifica la sezione Approssimazione della forza peso" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Forza_peso&amp;action=edit&amp;section=2" title="Edit section&#039;s source code: Approssimazione della forza peso"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Acceleration-due-to-Gravity-on-Earth.png" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/3/39/Acceleration-due-to-Gravity-on-Earth.png/310px-Acceleration-due-to-Gravity-on-Earth.png" decoding="async" width="310" height="328" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/3/39/Acceleration-due-to-Gravity-on-Earth.png/465px-Acceleration-due-to-Gravity-on-Earth.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/3/39/Acceleration-due-to-Gravity-on-Earth.png/620px-Acceleration-due-to-Gravity-on-Earth.png 2x" data-file-width="1031" data-file-height="1090" /></a><figcaption>Contributo della forza centrifuga all'accelerazione gravitazionale.</figcaption></figure> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Gravity_anomalies_on_Earth.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/1/14/Gravity_anomalies_on_Earth.jpg/310px-Gravity_anomalies_on_Earth.jpg" decoding="async" width="310" height="192" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/1/14/Gravity_anomalies_on_Earth.jpg/465px-Gravity_anomalies_on_Earth.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/1/14/Gravity_anomalies_on_Earth.jpg 2x" data-file-width="540" data-file-height="334" /></a><figcaption>Anomalie del campo gravitazionale terrestre in <a href="/wiki/Milligal" class="mw-redirect" title="Milligal">milligal</a> (1 mGal = 10<sup>-5</sup> m/s<sup>2</sup>), rispetto al valore stimato considerando la variazione del raggio terrestre.</figcaption></figure> <p>La <i>forza peso</i> è generalmente espressa attraverso la <a href="/wiki/Principi_della_dinamica#Secondo_principio_detto_di_proporzionalità_o_di_Newton_o_di_conservazione" title="Principi della dinamica">seconda legge della dinamica</a>, e cioè:<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">&#91;</span>2<span class="cite-bracket">&#93;</span></a></sup> </p> <dl><dd><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 {\vec {F}}=m\,{\vec {g}}}"> <semantics> <mrow class="MJX-TeXAtom-ORD"> <mstyle displaystyle="true" scriptlevel="0"> <mrow class="MJX-TeXAtom-ORD"> <mrow class="MJX-TeXAtom-ORD"> <mover> <mi>F</mi> <mo stretchy="false">&#x2192;<!-- → --></mo> </mover> </mrow> </mrow> <mo>=</mo> <mi>m</mi> <mspace width="thinmathspace" /> <mrow class="MJX-TeXAtom-ORD"> <mrow class="MJX-TeXAtom-ORD"> <mover> <mi>g</mi> <mo stretchy="false">&#x2192;<!-- → --></mo> </mover> </mrow> </mrow> </mstyle> </mrow> <annotation encoding="application/x-tex">{\displaystyle {\vec {F}}=m\,{\vec {g}}}</annotation> </semantics> </math></span><img src="https://wikimedia.org/api/rest_v1/media/math/render/svg/c3199ef78ecb558d7c5f8a1836be4affacdce9a4" class="mwe-math-fallback-image-inline mw-invert skin-invert" aria-hidden="true" style="vertical-align: -0.671ex;
