Mutemo waKepler - matambudziko nemhinduro

1. Kureba kweNyika kubva kuZuva i149.6 x 10 ⁶ km uye nguva yekuchinja kweNyika igore rimwe chete. Verenga T ² / r ³

Zvinozivikanwa:

T = gore 1, r = 149.6 x 10 ⁶ km

Zvaidiwa : T ² / r ³ = … ?

Mhinduro :

k = T² /r³ = 1² / (149.6 x 10⁶)³ = 1 / (3348071.9 x 10¹⁸) = 2.98 x 10^-25 gore²/ km³

2. Chisingachinji cheUniversal (G) = 6.67 x 10 ^-11 Nm ² /kg ² uye Sun's 1.99 x 10 ³⁰ kg.

3. Avhareji yedaro reNyika kubva kuZuva i149.6 x 10 ⁶ km uye avhareji yedaro reMercury kubva kuZuva i57.9 x 10 ⁶ km. Nguva yekuchinja kwenyika igore rimwe chete, inguvai yekuchinja kweMercury?

Zvinozivikanwa:

r yePasi = 149.6 x 10 ⁶ km

r yemercury = 57.9 x 10 ⁶ km

T yePasi = gore rimwe chete

Wanted: T ye mercury?

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
