Nyob rau hauv physics, lub cim ntawm ib yam khoom acceleration nyob ntawm nws cov kev taw qhia. Ib qho acceleration tuaj yeem ua rau ceev rau nce , txo qis, thiab txawm nyob zoo ib yam! Acceleration qhia koj tus nqi ntawm qhov ceev hloov. Vim lub ceev yog vector, koj yuav tsum xav txog qhov kev hloov pauv rau nws qhov loj thiab kev taw qhia.
Ib yam li ntawd, dab tsi ua rau kev hloov pauv hauv qhov nrawm?
Acceleration thiab ceev Newton txoj cai thib ob hais tias thaum lub zog tas li ua rau lub cev loj, nws ua rau nws kom nrawm, i.e., rau hloov nws ceev , ntawm tus nqi tas li. Hauv qhov yooj yim tshaj plaws, lub zog siv rau ib qho khoom thaum so ua rau nws kom nrawm nrawm ntawm lub zog.
Ib tug kuj yuav nug, vim li cas qhov nrawm nce raws li qhov khoom ntog? Thaum twg khoom poob mus rau hauv av, lub ntiajteb txawj nqus ua rau lawv ceev. Lub ntiajteb txawj nqus ua rau ib qho khoom rau poob mus rau hauv av sai thiab sai ceev qhov ntev khoom poob . Qhov tseeb, nws nrawm nce los ntawm 9.8 m / s2, yog li los ntawm 1 thib ob tom qab ib khoom pib poob , nws ceev yog 9,8m.
Tom qab ntawd, lo lus nug yog, dab tsi yog 3 txoj hauv kev uas ib qho khoom tuaj yeem hloov nws qhov nrawm?
Muaj peb txoj kev uas ib yam khoom ua tau ceev: a hloov ceev , a hloov hauv direction, lub a hloov hauv ob leeg ceev thiab kev taw qhia.
Yog vim li cas acceleration txo qis raws li kev tshaj tawm?
Txawm hais tias koj nyob rau hauv qhov tseeb speeding, nce koj ceev , tus nqi uas koj tab tom ceev tau txo. Ib kev ceev tau txo. Vim kev ceev tseem zoo koj ceev yog nce tab sis qhov loj ntawm qhov ntawd kev ceev yog txo.

Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm qhov nrawm thiab nrawm?
Kev sib piv daim duab piv rau Kev Sib Piv Ceev Ceev Tus Nqi Hloov ntawm qhov kev ncua deb Hloov pauv hloov thaum lub cev rov qab mus rau nws qhov chaw pib Yuav tsis xoom Yuav yog xoom Tsiv khoom Ceev ntawm cov khoom txav tsis tuaj yeem tsis zoo. Kev nrawm ntawm cov khoom txav tuaj yeem yog qhov zoo, tsis zoo lossis xoom
Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov nrawm thiab nrawm nrog piv txwv?
Qhov laj thawj yog yooj yim. Kev nrawm yog lub sij hawm tus nqi ntawm qhov khoom txav mus raws txoj kev, thaum lub nrawm yog tus nqi thiab kev taw qhia ntawm qhov khoom txav. Piv txwv li, 50 km / h (31 mph) piav qhia txog qhov ceev ntawm lub tsheb uas taug kev raws txoj kev, thaum 50 km / teev sab hnub poob piav qhia txog qhov nrawm uas nws tab tom taug kev
Ib qho piv txwv zoo ntawm kev nrawm nrawm yog dab tsi?
Kev sib tsoo, photons, pib los ntawm kev so thiab dhia mus rau qee qhov nrawm yog txhua yam piv txwv ntawm cov khoom lossis cov xwm txheej uas qhov kev hloov pauv sai sai tshwm sim. Photons raug tso tawm ntawm qhov nrawm ntawm lub teeb ntsig txog qhov nruab nrab thiab lawv hloov nrawm thaum nkag mus rau lwm qhov nruab nrab
Dab tsi yog txhais los ntawm kev nrawm thiab nrawm?
Hauv kev xaus, ceev thiab tshaj tawm yog kinematic ntau uas muaj cov ntsiab lus sib txawv. Ceev, ua ib tug scalar kom muaj nuj nqis, yog tus nqi ntawm ib yam khoom npog qhov deb. Qhov nruab nrab ceev yog qhov kev ncua deb (ib qho scalar kom muaj nuj nqis) ib lub sij hawm piv. Kev nrawm yog tus nqi ntawm txoj haujlwm hloov
