Xawaaruhu waa tiro vector ah, halka xawaaruhu yahay tiro scalar ah. Xawaaruhu wuxuu leeyahay baaxad iyo jiho labadaba, halka xawaaruhu uu leeyahay baaxad oo keliya. Cutubka caalamiga ah waa mitir ilbiriqsikiiba, oo loo soo gaabiyo m/s ama ms -1 . Astaantiisu waa v ( xawaaraha ).
Xawaaraha celceliska iyo xawaaraha celceliska
Tusaalaha dhibaatooyinka.
1. Arday ayaa lugeynaya bari 2 mitir 1 ilbiriqsi gudaheed. Waa maxay celceliska xawaaraha iyo baaxadda celceliska xawaaraha ardayga?
Dood
Xawaaraha celceliska = 2m/s
Xawaaraha celceliska = 2m/s
Aarax = jihada barokac = bari
2. Arday ayaa lugeynaya bari 2 mitir 1 ilbiriqsi gudaheed, ka dibna wuxuu lugeynayaa galbeed 1 mitir 2 ilbiriqsi gudaheed. Waa maxay celceliska xawaaraha ardayga iyo celceliska xawaaraha?
Dood
Xawaaraha celceliska = (2 mitir + 1 mitir) / (1 ilbiriqsi + 2 ilbiriqsi) = 3 mitir / 3 ilbiriqsi = 1 m/s
dhunkasho = (2 mitir – 1 mitir) / (1 ilbiriqsi + 2 ilbiriqsi) = 1 mitir / 3 ilbiriqsi = 1/3 m/s
Aarax = jihada dhaqdhaqaaqa = bari.
Xawaaraha degdega ah iyo xawaaraha degdega ah
Xawaaraha degdega ah = masaafo aad u yar / waqti aad u gaaban. Si kale haddii loo dhigo, xawaaraha degdega ah waa masaafo aad u yar oo la safray muddo aad u gaaban. Haddii aad waligaa baaskiil ama gaari wadatay, waxaad arki doontaa in xawaaraha mootada ama gaariga uu had iyo jeer isbeddelayo daqiiqad kasta inta mootada ama gaarigu socdo. Xawaarahan degdega ah waxaa tilmaamaya mitirka xawaaraha.
Cabbirka xawaaraha degdega ah = barokac aad u yar / muddo aad u gaaban. Si kale haddii loo dhigo, barokac aad u yar ayaa socday muddo aad u gaaban.
Waa muhiim in la ogaado inaan xawaaraha ku beddeli karno xawaare . Xawaaraha waxaa loo arkaa inuu la mid yahay xawaaraha sababtoo ah masaafada iyo barokaca waa siman yihiin haddii ay aad u yar yihiin. Inkasta oo masaafada iyo barokaca aysan had iyo jeer isku mid ahayn (fiiri doodda masaafada iyo barokaca), haddii masaafada iyo barokaca ay aad u yar yihiin, waa inay lahaadaan qiimo isku mid ah.
