Boima ba Matla a khoheli - Mathata le Litharollo

5 Matla a khoheli Boima - Mathata le Litharollo

1. Matla a khoheli a sebetsang nthong e holim'a Lefatše ke afe ? Boima ba Lefatše = 5.98 x 10 ²⁴ kg, boima ba ntho = 1000 kg, radius ea Lefatše ke 6.38 x 10 ⁶ m.

Tse tsejoang:

Boima ba Lefatše (m _E ) = 5.98 x 10 ²⁴ kg

Boima ba ntho (mo ₎ = 1000 kg

Radiyo ya Lefatshe (r _E ) = 6.38 x 10 ⁶ m

Sephetho sa bokahohleng (G) = 6.67 x 10 ^-11 N m ² / kg ²

Ho potlaka ka lebaka la matla a khoheli (g) = 9.8 m/s ²

Ho Batloa: Matla a Matla a Khoheli

Tharollo:

w = boima, F = matla, G = ntho e sa fetoheng ka ho felletseng, m _E = Boima ba Lefatše , m _o = boima ba ntho , r = sebaka se pakeng tsa setsi sa Lefatše le ntho.

Ntho e holim'a Lefatše, kahoo r = radius ea Lefatše

Boima ba ntho ( molao oa bobeli oa Newton oa motsamao ):

w = mg

w = (1000 kg)(9.8 m/s ² )

w = 9800 N

2. Matla a khoheli a sebetsang nthong e bophahamo ba limithara tse 10,000 ka holimo ho Lefatše ke afe? Boima ba Lefatše = 5.98 x 10 ²⁴ kg, boima ba ntho = 1000 kg, radius ea Lefatše ke 6.38 x 10 ⁶ m.

Tharollo:

3. Boima ba sefofane sa sepakapaka ke w. Haeba D = bophara ba Lefatše, fumana boima ba sefofane sa sepakapaka ha sefofane sa sepakapaka se le ho 2D ka holim'a Lefatše.

Tse tsejoang:

D = Bophara ba Lefatše,

R = radius ea Lefatše

1 D = 2 R, 2 D = 4 R

Ho batloa: boima ba sefofa-sebakeng bo ho 2D ka hodima bokahodimo ba Lefatshe?

Tharollo:

4. Karolelano ea boima ba polanete A le polanete B ke 2: 3, ha karolelano ea radius ea polanete A le polanete B e le 1: 2. Haeba boima ba ntho e polaneteng A e le w, boima ba ntho e polaneteng B ke bofe.

Tse tsejoang:

Boima ba polanete A (m _A ) = 2

Boima ba polanete B (m _B ) = 3

Radius ea polanete A (r _A ) = 1

Radius ea polanete B (r _B ) = 2

Boima ba ntho = m

Boima ba ntho polaneteng A = w

Ho batloa: Boima ba ntho polaneteng ea B

Tharollo:

Tekanyo ea matla a boima ho tsoa molaong oa Newton oa matla a khoheli:

w = boima, G = matla a khoheli a sa fetoheng, M = boima ba polanete, m = boima ba ntho, r = sebaka se pakeng tsa ntho le polanete. Haeba ntho e holim'a polanete e le holim'a r = radius ea polanete.

Boima ba ntho polaneteng A:

Boima ba ntho polaneteng ea B:

Boima ba ntho bo tshwana kahoo e leng se ka nkela m sebaka ka w/2G.

5. Rokete e nang le boima ba w e betsetsoa ka ho otloloha ho tloha holim'a Lefatše. D ke bophara ba Lefatše. Ha rokete e le bophahamong ba 0.5 D ka holim'a Lefatše, joale boima ba rokete ke bofe.

Tse tsejoang:

Boima ba rokete = w

Radius ea Lefatše = sebaka ho tloha bohareng ba Lefatše = R

Bophara ba Lefatše = D = 2R

Ho batloa: Boima ba rokete ha rokete e le bophahamong ba 0.5 D ka hodima bokahodimo ba Lefatshe.

Tharollo:

0.5 D = 0.5 (2R) = R

Sebaka sa rokete ho tloha bohareng ba Lefatše = radius ea Lefatše + radius ea rokete ho tloha holim'a Lefatše = R + R = 2R

Boima ke matla a khoheli a sebetsang nthong. Matla a khoheli (F) a lekana ka tsela e fapaneng le sekwere sa sebaka ho tloha bohareng ba lefats'e (R) hoo boima bo lekanang ka tsela e fapaneng le sekwere sa sebaka.
