Acceleration yog qhov thib ob derivative ntawm kev hloov pauv nrog rau lub sijhawm, lossis thawj qhov kev hloov pauv ntawm nrawm Nrog rau lub sijhawm: Inverse txheej txheem: Kev koom ua ke . Kev nrawm yog ib ib qho ntawm acceleration ntawm lub sij hawm. Kev tshem tawm yog ib qho ib qho ntawm nrawm dhau sijhawm.
Hais txog qhov no, dab tsi yog qhov tseem ceeb ntawm kev tshaj tawm?
Cov ib qho ntawm acceleration nyob rau lub sij hawm yog hloov nyob rau hauv nrawm (∆v = ∫a dt). Cov ib qho ntawm kev tshaj tawm Lub sijhawm dhau los yog qhov hloov pauv hauv txoj haujlwm (∆s = ∫v dt).
Tsis tas li ntawd, yuav ua li cas yog tias koj koom nrog kev hloov chaw? Nyob rau hauv ib txoj kev ua lej ncaj qha, tus ib qho ntawm hloov chaw nrog rau lub sij hawm tsuas yog tas li ntawm kev koom ua ke . Yog koj xav txog kev tshaj tawm raws li tus nqi hloov ntawm hloov chaw , koj ua tau xav txog hloov chaw raws li tus nqi hloov ntawm ib qho taw tes, yog li ntawd tus ib qho ntawm hloov chaw yuav tsuas yog ib qho point.
Ib yam li ntawd, nws yog nug, dab tsi yog qhov tseem ceeb ntawm kev tshaj tawm muab rau koj?
Kev nrawm yog tus nqi ntawm kev hloov hauv txoj haujlwm, yog li nws qhov tseeb integral yuav muab peb qhov txav ntawm qhov khoom txav. Ceev yog tus nqi ntawm kev hloov nyob rau hauv tag nrho cov kev ncua deb, yog li nws qhov tseeb integral yuav muab peb qhov kev ncua deb tau them tag nrho, tsis hais txoj haujlwm.
Kev ua haujlwm nrawm yog dab tsi?
Cov nrawm ntawm ib yam khoom yog tus nqi ntawm kev hloov ntawm nws txoj hauj lwm nrog rau ib tug ncej ntawm kev siv, thiab yog a muaj nuj nqi ntawm lub sijhawm. Kev nrawm yog sib npaug rau qhov tshwj xeeb ntawm cov khoom ceev thiab kev taw qhia ntawm kev txav (piv txwv li 60 km / h mus rau sab qaum teb).

Yuav ua li cas tshwm sim thaum physiological ceev yog siab tshaj arithmetic ceev?
Lub physiological ceev los yog tiag tiag pejxeem yog tus naj npawb ntawm cov neeg nyob rau hauv ib cheeb tsam ntawm arableland. Lub cev muaj zog ntau dua qhia tau hais tias cov av ua liaj ua teb muaj ntau dua thiab tuaj yeem ncav cuag nws cov khoom tso tawm sai dua li lub teb chaws uas muaj qhov ntom ntom ntawm lub cev
Yuav hloov pauv li cas thaum tsis ceev?
Velocity yog vector kom muaj nuj nqis, uas txhais tau hais tias nws qhia qhov loj thiab kev taw qhia. Yog li ib txoj hauv kev nrawm ntawm ib qho khoom tuaj yeem hloov pauv, yam tsis muaj nws hloov pauv yog hloov nws txoj kev coj. Ib qho piv txwv ntawm qhov no yog nyob rau hauv lub voj voog, qhov twg ib qho khoom ib txwm hloov kev taw qhia thaum muaj qhov ceev tsis tu ncua
Koj yuav tsum tau ceev faj txog kev nyab xeeb dab tsi thaum saib hnub ci eclipse?
Kev Tiv Thaiv Kev Nyab Xeeb Thaum Lub Yim Hli 21 SolarEclipse Tsis txhob ntsia lub hnub ncaj qha. Cov ntxaij lim dej hnub ci, lossis tsom iav dab noj hnub, muab txoj hauv kev nyab xeeb nkaus xwb los saib ncaj qha ntawm ib nrab lossis tag nrhoeclipse. Xyuas kom lub hnub ci saib lossis tsom iav suav nrog tus neeg tsim khoom lub npe thiab chaw nyob. Tsis txhob siv cov tsom iav hnub ci uas muaj hnub nyoog tshaj peb xyoos lossis muaj cov lo ntsiab muag khawb
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Thaum twg koj yuav tsum siv correlation thiab thaum twg koj yuav tsum siv yooj yim linear regression?
Regression feem ntau yog siv los tsim cov qauv / qhov sib npaug los kwv yees cov lus teb tseem ceeb, Y, los ntawm cov txheej txheem kwv yees (X) sib txawv. Kev sib raug zoo feem ntau yog siv los ua kom sai thiab ua kom luv luv cov kev taw qhia thiab lub zog ntawm kev sib raug zoo ntawm ib pawg ntawm 2 lossis ntau tus lej sib txawv
