Yerning tortishish kuchi sahifasining manbasini koʻrish

'''Yerning tortishish kuchi''', '''''{{Mvar|g}}''''' bilan belgilangan, [[Gravitatsiya|tortishish]] ([[Yer]] ichidagi [[Ommaviy taqsimot|massa taqsimoti]]) va [[markazdan qochma kuch]] ([[Yerning aylanishi]]dan) birgalikda taʼsiri tufayli jismlarga beriladigan [[Aniq kuch|aniq]] [[tezlanish]]dir <ref name="Boynton">{{Konferensiya manbasi|last=Boynton|first=Richard|date=2001|title=''Precise Measurement of Mass''|booktitle=Sawe Paper No. 3147|publisher=S.A.W.E., Inc.|location=Arlington, Texas|url=http://www.space-electronics.com/Literature/Precise_Measurement_of_Mass.PDF|accessdate=22 December 2023|archivedate=27 February 2007|archiveurl=https://web.archive.org/web/20070227132140/http://www.space-electronics.com/Literature/Precise_Measurement_of_Mass.PDF}}</ref><ref>{{Kitob manbasi |last=Hofmann-Wellenhof |first=B. |year=2006 |title=Physical Geodesy |url=https://archive.org/details/physicalgeodesy0000bern |publisher=Springer |edition=2nd |isbn=978-3-211-33544-4}} § 2.1: „The total force acting on a body at rest on the earth’s surface is the resultant of gravitational force and the centrifugal force of the earth’s rotation and is called gravity.“</ref>. Bu [[Vektor (matematika)|vektor]] miqdori boʻlib, uning yoʻnalishi [[Limb|plumb bobga]] toʻgʻri keladi va kuch yoki kattalik [[Yevklid fazosi|norma]] bilan beriladi. <math>g=\|\mathit{\mathbf{g}}\|</math> .

[[Xalqaro birliklar tizimi|SI birliklarida]] bu tezlanish [[Metr/sekund kvadrat|sekundiga kvadrat metrda]] (belgilarda, [[Metr|m]] / [[Soniya|s]] <sup>2</sup> yoki m · s <sup>−2</sup>) yoki ekvivalentda [[kilogramm]] boshiga [[Nyuton (oʻlchov birligi)|nyutonlarda]] (N / kg yoki N · kg <sup>−1</sup>) ifodalanadi. Yer yuzasiga yaqin joyda tortishish tezlashuvi 2 ta [[Muhim raqamlar|muhim raqamga]] aniqlik bilan {{Convert|9.8|m/s2|abbr=on}} ni tashkil qiladi. . Bu shuni anglatadiki, [[Drag (fizika)|havo qarshiligi]] taʼsiriga eʼtibor bermasdan, [[Erkin tushish|erkin tushgan]] jismning [[Tezlik|tezligi]] {{Convert|9.8|m/s|ft/s}} har soniyada. Bu miqdor baʼzan norasmiy ravishda ''kichik {{Mvar|g}}'' deb ataladi (aksincha, [[Gravitatsion doimiy|tortishish doimiysi]] ''{{Mvar|G}}'' ''katta {{Mvar|G}}'' deb ataladi).
