Kuthamanga chifukwa cha mphamvu yokoka - mavuto ndi mayankho

1. Ndi chiyani kuthamanga chifukwa cha mphamvu yokoka pamwamba pa Mwezi? Mwezi Unyinji = 7.35x10 pa²² kg, utali wa Mwezi ndi 1.7 × 10⁶ m, chosasintha cha chilengedwe chonse ndi 6.67 × 10^-11 N m² / kg²

Fomula ya Lamulo lachiwiri la Newton la kayendedwe :

Fomula ya Lamulo la Newton la mphamvu yokoka padziko lonse lapansi :

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 kwa mphamvu yokoka = ¼ g. Ngati g = 9.8 m/s², pa R pamwamba pa dziko lapansi, kuthamanga chifukwa cha mphamvu yokoka = 2.45 m/s².

1. Lamulo la Newton la mavuto a mphamvu yokoka padziko lonse lapansi ndi mayankho ake
2. Mphamvu yokoka, mavuto olemera, ndi mayankho
3. Kuthamanga chifukwa cha mavuto ndi mphamvu yokoka
4. Mavuto ndi mayankho a satellite ya geosynchronous
5. Mavuto ndi mayankho a malamulo a Kepler
