Lub sideways (dab tsi astronomers hu ua tangential) ceev yog kwv yees 30 kilometers (18 mais) ib ob, uas yog incredibly ceev. Tab sis tom qab ntawd, peb taug kev ncig lub voj voog uas ze li ib txhiab mais hauv ib puag ncig txhua xyoo!
Lub ntiaj teb tangential ceev yog dab tsi?
Lub tangential ceev ntawm lub ntiaj teb kev sib hloov ntawm ib qho taw tes ntawm lub ntiaj teb tuaj yeem kwv yees los ntawm kev sib npaug ntawm qhov nrawm los ntawm cov cosine ntawm latitudePiv txwv li, Kennedy Space Center yog nyob rau ntawm latitude 28.59° N, uas yields ib ceev ntawm: cos(28.59°) × 1674.4 km/h=1470.2 km/h.
Yuav ua li cas yog lub tangential tshaj tawm ntawm lub ntiaj teb ntawm txoj kab nruab nrab?
Vim li no, lub tangential tshaj tawm ntawm tus neeg sawv ntawm txoj kab nruab nrab yog 463.826m/s 463.826 m / s.
Lub ntiaj teb puas muaj tangential tshaj tawm?
Kev hloov pauv ntawm lub ntiaj teb sab hnub poob mus rau sab hnub tuaj ua rau tag nrho cov ntsiab lus ntawm lub ntiaj teb (tshwj tsis yog cov ncej lawv tus kheej) txav mus rau sab hnub tuaj nrog qee qhov nrawm nrawm … Nws yog qhov deb ntawm qhov qhov nruab nrab ntawm kev sib hloov, lossis lub vojvoog ntawm kev sib hloov, uas cuam tshuam rau qhov nrawm nrawm ntawm ib qho khoom nrog qhov nrawm nrawm.
Lub cim rau tangential tshaj tawm yog dab tsi?
Tus Qauv rau Tangential Velocity
Nws yog txhais los ntawm \omega thiab nws cov qauv ntsuas yog radians ib ob. Nws txawv ntawm qhov kev tshaj tawm tawm, raws li nws tsuas yog cuam tshuam nrog cov khoom txav hauv ib ncig. Yog li ntawd, nws ntsuas tus nqi ntawm qhov angular hloov chaw yog swept.
