Yog li, nyob ntawd yog 360 degrees mus ncig tag nrho lub voj voog. Nyob ntawd yog 60 min arc , arcminutes, ib degree ,,ua 60 vib nas this arc , arcseconds, hauv arcminute.
Yog li ntawd, pes tsawg vib nas this ntawm arc nyob rau hauv 360 degrees?
Lub voj voog puv muaj 360 degrees . Ib degree tuaj yeem muab faib ua 60 feeb ntawm arc . Cov feeb ntawm arc yuav tsum tsis txhob totaub nrog feeb ntawm lub sijhawm. Txhua feeb ntawm arc muaj 60 vib nas this arc , yog a ob arc yog lub kaum sab xis uas yog 1/3, 600 ntawm a degree.
Tsis tas li ntawd, 1 arc thib ob yog dab tsi? Arc Ob . Ib chav ntsuas angular sib npaug 1 /60 ib arc feeb, lub 1 /3600 ntawm ib degree. Cov arc ob yog npe. (tsis txhob tsis meej pem nrog lub cim rau ntiv tes).
Yog li ntawd, pes tsawg vib nas this ntawm arc nyob rau hauv ib tug degree?
Qhov ntsuas angular ntawm ib qho khoom feem ntau yog qhia hauv qib , arcminutes lossis arcseconds. Ib yam li ib teev muab faib ua 60 feeb thiab ib feeb ua 60 vib nas this , a degree muab faib ua 60 arcminutes thiab ib arcminute muab faib ua 60 arcseconds.
Nws siv sijhawm ntev npaum li cas hnub qub kom txav 1 arc feeb?
Xyuas koj cov lus teb: Tsis yog, nco ntsoov qhov ntawd cov hnub qub txav 15 ° hauv 60 feeb . Cov tus nqi ntawm angular motion yog cov tib yam hauv lwm qhov chaw ntawm tus ntuj, txawm koj ua tau 'tsis yog ntsuas tus ces kaum nrog koj txhais tes vim koj tsis nyob tus nruab nrab ntawm tus lub voj voog.
