Ukusheshisa ngenxa yamandla adonsela phansi - izinkinga nezixazululo

1. Kuyini ukusheshisa okubangelwa amandla adonsela phansi ebusweni beNyanga? Isisindo seNyanga = 7.35 x 10 ²² kg, irediyasi yeNyanga ingu- 1.7 x 10 ⁶ m, i-universal constant ingu- 6.67 x 10 ^-11 N m ² / kg ²

Isixazululo

Ifomula yomthetho wesibili wokunyakaza kaNewton :

Ifomula yomthetho kaNewton wamandla adonsela phansi omhlaba wonke :

G = okungaguquki okujwayelekile, M = isisindo soMhlaba, m = isisindo sento, r = ibanga eliphakathi kwesikhungo soMhlaba nento. Uma into isendaweni yoMhlaba, r = irediyasi yoMhlaba

Faka u-F esilinganisweni 1 no-F esilinganisweni 2:

Kuyini ukusheshisa okubangelwa amandla adonsela phansi ebusweni beNyanga?

2. Ukusheshisa ngenxa yamandla adonsela phansi ebusweni boMhlaba kungu-g. Ku-R (R ubuso boMhlaba), ukusheshisa ngenxa yamandla adonsela phansi kungu-…

Isixazululo

R = Irediyasi yoMhlaba. Ku-R ngaphezu kobuso boMhlaba = ku-2R ngaphezu kwesikhungo soMhlaba.

Ku-R ngaphezu kobuso boMhlaba, ukusheshisa okubangelwa amandla adonsela phansi = ¼ g. Uma g = 9.8 m/s ² , ku -R ngaphezu kobuso boMhlaba, ukusheshisa okubangelwa amandla adonsela phansi = 2.45 m/s ².
