dab tsi yog qhov tseem ceeb ceev ntawm pob zeb
Apr 22, 2024
Qhov tseem ceeb ceev ntawm lub pob zeb yog hais txog qhov kev sib hloov ceev uas lub zog centrifugal sib npaug rau lub zog gravitational ua rau cov xov xwm sib tsoo hauv lub zeb. Tshaj li qhov ceev no, cov pob yog tuav tawm ntawm phab ntsa thiab tsis poob rov qab tab sis nyob twj ywm ntawm lub voj voog ntawm lub zeb.
(R) yog lub vojvoog ntawm lub pob zeb (hauv meters).
(g ) yog qhov acceleration vim lub ntiajteb txawj nqus (kwv yees li 9.81 m/s²).
Qhov tseem ceeb ceev ceev ntawm lub pob zeb yog ib qho tseem ceeb nyob rau hauv cov txheej txheem sib tsoo vim nws txiav txim siab qhov siab tshaj plaws ceev ntawm lub pob zeb tuaj yeem ua haujlwm yam tsis muaj kev puas tsuaj lossis hnav ntau dhau. Kev ua haujlwm ntawm lub pob zeb ntawm qhov nrawm qis dua qhov nrawm nrawm tuaj yeem ua rau kev sib tsoo tsis zoo, thaum dhau qhov nrawm nrawm tuaj yeem ua rau hnav ntau dhau ntawm cov khoom siv zeb.
