I-amandla adonsela phansi Kungokunye ukuxhumana okuyisisekelo okulawula indawo yonke futhi okwenza izinto nezidalwa eziphilayo zihlale zigxilile ebusweni bomhlaba, ngenxa yokuheha okuya enkabeni yoMhlaba.
Ngakolunye uhlangothi, amandla adonsela phansi angachazwa njengomkhakha wamandla adonsela phansi osebenza emizimbeni emikhulu, ebahehe komunye nomunye. Ngakolunye uhlangothi, kujwayelekile ukubhekisa kumandla adonsela phansi njengokushesha lapho izidumbu zikhangwa khona eMhlabeni. Lokhu kusheshisa kunenani elilinganisiwe lamamitha ayi-9.81 ngesekhondi ngalinye.
Ukube ukushesha kwamandla adonsela phansi bekukukhulu, izinto eziwa mahhala zingathatha isikhathi esincane ukufinyelela phansi futhi ukuhamba kwethu, ngokwesibonelo, bekuyoba nzima kakhulu. Ngakolunye uhlangothi, ukube bekungaphansi, besizohamba njengokuhamba kancane, ngoba bekungathatha isikhathi esiningi ukuthi unyawo ngalunye lubuyele emhlabathini. Lokhu kufakazelwe lapho osomkhathi behamba eNyangeni lapho amandla adonsela phansi engaphansi.
Ngenxa yeJiyomethri yoMhlaba, ezigxotsheni amandla adonsela phansi amakhulu kakhulu (9.83 m / s2) nasendaweni ye-equatorial iphansi ngandlela thile (9.79 m / s2). Inkambu yamandla adonsela phansi kaJupiter inamandla kakhulu kuneplanethi yethu, kuyilapho iMercury incane kakhulu.

Izazi zamandla adonsela phansi
Ngenxa yobunzima bayo nobunzima bokuhlaziywa, ukutadisha kwamandla adonsela phansi kungcwelise ososayensi ababaluleke kakhulu esintwini. Ngokokulandelana kwezikhathi, u-Aristotle, uGalileo Galilei, u-Isaac Newton no-Albert Einstein babephethe iqhaza elibaluleke kakhulu kulokhu.
Akungabazeki ukuthi amabili okugcina agqamile, owokuqala wokunikeza ubudlelwano phakathi kokuqina kokuhehayo maqondana nebanga eliphakathi kwezinto ezikhangiwe nenqwaba yazo, kuyilapho owesibili kunguyena othole leyo ndaba nendawo kuyasebenzisana, udaba luphendukezela isikhala , ekhiqiza amandla adonsela phansi. Yomibili le mibono yakhiwa kabanzi ngokwakhiwa kwezibalo futhi kubhekwa namuhla njengenye yezinto ezibaluleke kakhulu emlandweni wesayensi.
Izibonelo zamandla adonsela phansi
Isenzo samandla adonsela phansi senzeka ngaso sonke isikhathi. Nazi izibonelo ezibonisa:
- Isenzo esilula sokuma noma kuphi kungenxa yamandla adonsela phansi.
- Ukuwa kwezithelo zezihlahla.
- Izimpophoma ezinkulu ezimpophomeni.
- Ukunyakaza kokuhumusha okwenziwa yinyanga ezungeze uMhlaba.
- Amandla okumele asebenze lapho egibela ibhayisikili ukuze angawi.
- Amaconsi emvula awayo.
- Yonke into eyakhiwe ngabantu ihlala imile futhi ingaphezulu komhlaba ngenxa yamandla adonsela phansi.
- Ukwehliswa komzimba lapho umzimba uphonswa phezulu kungenxa yamandla adonsela phansi.
- Ukuhamba kwe-pendulum, nanoma yiluphi uhlobo lokunyakaza kwe-pendulum.
