'''Normalkraften''' är den vinkelräta komposanten av den kontaktkraft som hindrar ett objekt att tränga igenom en yta.<br />
<br />
På mikroskopisk skala har normalkraften sitt ursprung i de [[elektromagnetiska krafter]] som verkar mellan atomerna i kropparnas ytor.<br />
<br />
Ett vanligt missförstånd är att normalkraften är en reaktionskraft till tyngdkraften i enlighet med [[Newtons tredje lag|Newtons rörelselagar]].<ref>http://www.regentsprep.org/Regents/physics/phys01/friction/normal.htm</ref> Så är inte fallet, och normalkraften är heller inte nödvändigtvis lika stor som den gravitationskraft som verkar på föremålet.<br />
<br />
Normalkraft per area kallas [[normalspänning]].<br />
