Simba regiravhiti Kurema - Matambudziko neMhinduro

5 Simba regiravhiti Kurema - Matambudziko neMhinduro

1. Chii chinonzi simba regiravhiti rinoshanda pachinhu chiri pamusoro peNyika? Huremu hwenyika = 5.98 x 10 ²⁴ kg, huremu hwechinhu = 1000 kg, nharaunda yeNyika i6.38 x 10 ⁶ m.

Zvinozivikanwa:

Huremu hwepasi (m _E ) = 5.98 x 10 ²⁴ kg

Huremu hwechinhu (m _o ) = 1000 kg

Nharaunda yePasi (r _E ) = 6.38 x 10 ⁶ m

Chisingachinji chepasi rose (G) = 6.67 x 10 ^-11 N m ² / kg ²

Kukurumidza kunokonzerwa negiravhiti (g) = 9.8 m/s ²

Kudiwa: Simba reGravity

Solution:

w = huremu, F = simba, G = chinhu chisingachinji, m _E = Huremu hwePasi , m _o = Huremu hwechinhu , r = chinhambwe chiri pakati pepakati pePasi nechinhu.

Chinhu chiri pamusoro peNyika, saka r = t iyo radius yeNyika

Kurema kwechinhu ( mutemo wechipiri waNewton wekufamba ):

w = mg

w = (1000 kg)(9.8 m/s ² )

w = 9800 N

2. Chii chinonzi simba regiravhiti rinoshanda pachinhu chiri pamamita zviuru gumi pamusoro penyika? Huremu hwenyika = 5.98 x 10 ²⁴ kg, huremu hwechinhu = 1000 kg, nharaunda yeNyika ndeye 6.38 x 10 ⁶ m.

Solution:

3. Huremu hwemuchadenga ndi w. Kana D = dhayamita yePasi, tsvaga huremu hwemuchadenga kana muchadenga uri pa2D pamusoro pePasi.

Zvinozivikanwa:

D = Dhayamita yePasi,

R = nharaunda yePasi

1 D = 2 R, 2 D = 4 R

Zvinodiwa: huremu hwemuchadenga pa2D pamusoro penyika?

Solution:

4. Chiyero chehukuru hwepuraneti A nepuraneti B i2 : 3, ukuwo chiyero cheradius yepuraneti A nepuraneti B chiri 1 : 2. Kana huremu hwechinhu chiri papuraneti A huri w, huremu hwechinhu chiri papuraneti B chii.

Zvinozivikanwa:

Huremu hwepuraneti A (m _A ) = 2

Huremu hwepuraneti B (m _B ) = 3

Nharaunda yepasi A (r _A ) = 1

Nharaunda yepasi B (r _B ) = 2

Huremu hwechinhu = m

Kurema kwechinhu chiri pasi pano A = w

Zvinodiwa: Kurema kwechinhu papuraneti B

Solution:

Kuenzanisa kwesimba rehuremu kubva kumutemo waNewton wegiravhiti:

w = huremu, G = simba rinokwevera pasi, M = huremu hwepuraneti, m = huremu hwechinhu, r = chinhambwe chiri pakati pechinhu nepuraneti. Kana chinhu chiri pamusoro pepuraneti chiri pamusoro pepuraneti r = radius yepuraneti.

Kurema kwechinhu papuraneti A:

Kurema kwechinhu papuraneti B:

Huremu hwechinhu hwakafanana saka zvinotsiva m ne w/2G.

5. Roketi ine huremu hwe w inoburitswa yakatwasuka kubva pamusoro peNyika. D ndiyo dhayamita yeNyika. Kana roketi iri pakakwirira kwe0.5 D pamusoro peNyika, saka huremu hweroketi chii.

Zvinozivikanwa:

Kurema kweroketi = w

Nharaunda yeNyika = daro kubva pakati peNyika = R

Dhayamita yeNyika = D = 2R

Zvinodiwa: Huremu hweroketi kana roketi iri pakakwirira kwe0.5 D pamusoro penyika.

Solution:

0.5 D = 0.5 (2R) = R

Kureba kweroketi kubva pakati peNyika = nharaunda yeNyika + nharaunda yeroketi kubva pamusoro peNyika = R + R = 2R

Kurema isimba rinokwevera zvinhu pasi rinoita basa pachinhu. Simba rinokwevera zvinhu pasi (F) rinoenderana nechikamu chedaro kubva pakati penyika (R) zvekuti uremu hwacho hunoenderana nechikamu chedaro.

1. Mutemo waNewton wematambudziko esimba rinokwevera pasi rose uye mhinduro dzawo
2. Simba resimba rinokwevera pasi, matambudziko ekurema, uye mhinduro
3. Kukurumidza kunokonzerwa nematambudziko egiravhiti nemhinduro
4. Matambudziko eGeosynchronous satellite uye mhinduro dzawo
5. Matambudziko emutemo waKepler nematambudziko ekugadzirisa matambudziko nemhinduro
