Iwu Newton nke ike ndọda zuru ụwa ọnụ - nsogbu na ngwọta

1. Anya dị n'etiti onye dị kilogram 40 na onye dị kilogram 30 bụ mita 2. Kedu ka ike ndọda si dị n'akụkụ nke ọzọ. Ihe na-agbanwe agbanwe zuru ụwa ọnụ = 6.67 x 10 ^-11 N m ² / kg ²

A maara:

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

Achọtara m: oke ike ndọda (F)?

Ngwọta:

2. Anya dị n'etiti Ụwa na Ọnwa (r) bụ 3.84 x 10 ⁸ m. Kedu ka ike ndọda nke ọ bụla si arụ ọrụ n'ebe ibe ya nọ?

A maara:

Oke nke ụwa (m _E ) = 5.97 x 10 ²⁴ kg

Oke ọnwa (m _M ) = 7.35 x 10 ²² kg

Anya dị n'etiti etiti ụwa na etiti ọnwa (r) = 3.84 x 10 ⁸ m

Ihe na-agbanweghi agbanwe (G) = 6.67 x 10 ^-11 N m ² / kg ²

Achọtara: Oke ike ndọda (F)

3. Gịnị bụ anya dị n'etiti Ụwa, otú ike ndọda nke ụwa na ọnwa si dị efu?

A maara:

Oke nke ụwa = 5.97 x 10 ²⁴ kg

Oke ọnwa = 7.35 x ¹⁰²² kg

Anya dị n'etiti etiti ụwa na etiti ọnwa (r) = 3.84 x 10 ⁸ m.

Ihe na-agbanweghi agbanwe zuru ụwa ọnụ ( G) = 6.67 x 10 ^-11 N m ² / kg ²

Achọtara: anya site n'ụwa

Ngwọta:

Ike ndọda nkịtị bụ efu.

Jiri usoro nhazi anọ:

A = – 6.35

B = – 7.68 x 10 ⁸

C = 87.76 x 10 ^-14
