Kuthamanga chifukwa cha mphamvu yokoka - mavuto ndi mayankho

1. Kodi mphamvu yokoka imathamanga bwanji pamwamba pa Mwezi? Kulemera kwa Mwezi = 7.35 x 10 ²² kg, utali wa Mwezi ndi 1.7 x 10 ⁶ m, nthawi zonse ndi 6.67 x 10 ^-11 N m ² / kg ²

Fomula ya lamulo lachiwiri la Newton la kuyenda :

Fomula ya lamulo la Newton la mphamvu yokoka ya chilengedwe chonse :

G = chosasinthika cha chilengedwe chonse, M = kulemera kwa dziko lapansi, m = kulemera kwa chinthu, r = mtunda pakati pa pakati pa dziko lapansi ndi chinthucho. Ngati chinthucho chili pamwamba pa dziko lapansi, r = utali wa dziko lapansi

M'malo mwa F mu equation 1 ndi F mu equation 2:

Kodi mphamvu yokoka pamwamba pa Mwezi imathamanga bwanji?

2. Kuthamanga chifukwa cha mphamvu yokoka pamwamba pa Dziko Lapansi ndi g. Pa R (R ndi pamwamba pa Dziko Lapansi), kuthamanga chifukwa cha mphamvu yokoka ndi…

Anakonza

R = Utali wa dziko lapansi. Pa R pamwamba pa dziko lapansi = pa 2R pamwamba pa pakati pa dziko lapansi.

Pa R pamwamba pa dziko lapansi, kuthamanga chifukwa cha mphamvu yokoka = ¼ g. Ngati g = 9.8 m/s ² , pa R pamwamba pa dziko lapansi, kuthamanga chifukwa cha mphamvu yokoka = 2.45 m/s ².
