Umthetho kaKepler - izinkinga nezixazululo

1. Ibanga loMhlaba ukusuka eLangeni lingu-149.6 x 10 ⁶ km kanti isikhathi sokuguquka koMhlaba singunyaka owodwa. Bala u-T ² / r ³

Kwaziwa:

T = unyaka ongu-1, r = 149.6 x 10 ⁶ km

Okufunwayo : T ² / r ³ = … ?

Isixazululo :

k = T² /r³ = 1² / (149.6x10⁶)³ = 1 / (3348071.9 x 10¹⁸) = 2.98 x 10^-25 Ngonyaka²/km³

2. I-Universal constant (G) = 6.67 x 10 ^-11 Nm ² /kg ² kanye ne-Sun's 1.99 x 10 ³⁰ kg.

3. Ibanga eliphakathi loMhlaba ukusuka eLangeni lingu-149.6 x 10 ⁶ km kanti ibanga eliphakathi leMercury ukusuka eLangeni lingu-57.9 x 10 ⁶ km. Isikhathi sokuguquka koMhlaba singunyaka owodwa, siyini isikhathi sokuguquka kukaMercury?

Kwaziwa:

r yoMhlaba = 149.6 x 10 ⁶ km

r ye-mercury = 57.9 x 10 ⁶ km

Unyaka ongu-1

Ufunwa: T ye-mercury?
