Umthetho kaNewton wamandla adonsela phansi omhlaba wonke – izinkinga nezixazululo

1. Ibanga phakathi komuntu ongama-40 kg nomuntu ongama-30 kg lingama-2 m. Ubukhulu bamandla adonsela phansi ngalinye liwasebenzisa kwelinye. I-Universal constant = 6.67 x 10 ^-11 N m ² / kg ²

Kwaziwa:

m ₁ = 40 kg, m ₂ = 30 kg, r = 2 m, G = 6.67 x 10 ^-11 N m ² / kg ²

Okufunwayo: ubukhulu bamandla adonsela phansi (F)?

Isixazululo:

2. Ibanga eliphakathi koMhlaba neNyanga (r) lingu-3.84 x 10 ⁸ m. Ubukhulu bamandla adonsela phansi ngalinye liwasebenzisa kwelinye?

Kwaziwa:

Isisindo somhlaba (m _E ) = 5.97 x 10 ²⁴ kg

Isisindo seNyanga (m _M ) = 7.35 x 10 ²² kg

Ibanga eliphakathi kwesikhungo soMhlaba nesikhungo seNyanga (r) = 3.84 x 10 ⁸ m

I-Universal constant (G) = 6.67 x 10 ^-11 N m ² / kg ²

Okufunwayo: Ubukhulu bamandla adonsela phansi (F)

Isixazululo:

3. Lingakanani ibanga ukusuka eMhlabeni, ubukhulu bamandla adonsela phansi omhlaba kanye nenyanga buyi-zero?

Kwaziwa:

Isisindo somhlaba = 5.97 x 10 ²⁴ kg

Isisindo seNyanga = 7.35 x ¹⁰²² kg

Ibanga eliphakathi kwesikhungo soMhlaba nesikhungo seNyanga (r) = 3.84 x 10 ⁸ m.

I-Universal constant ( G) = 6.67 x 10 ^-11 N m ² / kg ²

Kufunwa: ibanga ukusuka eMhlabeni

Isixazululo:

Amandla adonsela phansi aphelele ayi-zero.

Sebenzisa ifomula ye-quadratic:

A = – 6.35

B = – 7.68 x 10 ⁸

C = 87.76 x 10 ^-14
