Yog tsis muaj kev tiv thaiv ces tsis tas yuav muaj zog los tswj qhov ceev ntawm ib yam khoom . Raws li Newton thawj txoj cai lij choj, lub cev nyob rau hauv cov lus tsa suab nyob twj ywm thiab lub cev atrest nyob twj ywm kom txog thaum thiab tshwj tsis yog ua raws li los ntawm ib co sab nraud. zog.
Tsuas yog li ntawd, yuav tsum muaj zog dab tsi los nres ib yam khoom?
Qhov loj dua qhov nrawm ntawm kev txav khoom qhov loj dua quab yuam yuav tsum nres nws nyob rau hauv ib lub sij hawm muab. Fig. 1. Cov zog rau nres ib lub tsheb nyob ntawm nws lub zog. External non-zero net zog acting ib khoom yog sib npaug rau tus nqi ntawm kev hloov ntawm lub zog ntawm lub khoom.
Tsis tas li ntawd, lub zog dab tsi ua rau ntawm qhov khoom thaum so? Ib khoom thaum so nyob ntawm so thiab ib khoom nyob rau hauv tsab ntawv tsa suab nyob twj ywm nyob rau hauv cov lus tsa suab nrog tib ceev thiab nyob rau hauv tib txoj kev taw qhia tshwj tsis yog tias ua raws li ib tug unbalanced zog.
Tom qab ntawd, koj tuaj yeem hais li cas txog qhov nrawm ntawm qhov khoom txav yog tias tsis muaj lub zog ua rau nws?
Cov ceev , los yog qhov ceev, ntawm a txav khoom , yog tsis muaj zog ua ntawm nws, yuav nyob rau hauv ib txoj kab ncaj nraim nrog ib qho tas mus li ceev ( tsis muaj acceleration), raws li xav tau los ntawm Thawj ntawm Newton'slaws. Cov ceev ntawm a khoom yog tsis muaj zog yog tsis muaj zog acting ntawm nws ces khoom yog tsis yog nres thiab tsis txhob hloov ceev hauv obtect.
Lub zog twg ua raws li qhov kev taw qhia kom nres lossis qeeb nws?
Kev sib txhuam yog ib qho sab nraud zog uas ua opposite rau cov kev taw qhia ntawm tsab ntawv tsa suab (saib daim duab 4.3). Xav txog kev sib txhuam raws li kev tiv thaiv tsab ntawv tsa suab uas slows tej yam nqes . Xav txog lub rooj hockey huab cua. Thaum huab cua tig tawm, lub puck swb tsuas yog luv luv ua ntej kev sib txhuam qeeb nws mus rau a nres.

Puas yog nws muaj tseeb tias nyob rau hauv kev thauj mus los ntawm kev txav ntawm cov khoom hla ib daim nyias nyias yuav tsum muaj zog?
Hauv kev thauj mus los passive, kev txav ntawm cov khoom hla ib daim nyias nyias yuav tsum muaj zog. _ Muaj tseeb_ 5. Endocytosis yog ib txoj kev uas ib lub cell membrane nyob ib puag ncig thiab siv cov khoom los ntawm ib puag ncig. Ib daim nyias nyias uas tso cai rau qee cov ntaub ntawv dhau los qhia txog kev xaiv permeability
Dab tsi yog qhov tseem ceeb ntawm kev tawm hauv cov crystal kev loj hlob tsis muaj kev cuam tshuam?
Nws yog ib qho tseem ceeb uas yuav tsum tau ua kom qhov kev sim npog kom tsis txhob muaj plua plav thiab lwm yam khoom siv tsis xav tau los ntawm kev cuam tshuam kev loj hlob siv lead ua. Saib xyuas kev tsim cov muaju ntawm cov hlua txhua hnub. Sab laug tsis muaj kev cuam tshuam, cov muaju yuav tsum loj dua txhua hnub kom txog thaum cov tshuaj qhuav qhuav
Puas yog qhov ceev yog ib txoj kev txhim khu kev qha ntawm kev txheeb xyuas tag nrho cov khoom tsis paub?
Koj tuaj yeem txheeb xyuas cov khoom tsis paub los ntawm kev ntsuas nws qhov ntom thiab sib piv koj cov txiaj ntsig rau cov npe paub qhov ntom ntom. Qhov ntom = loj / ntim. Xav tias koj yuav tsum txheeb xyuas cov hlau tsis paub. Koj tuaj yeem txiav txim siab qhov loj ntawm cov hlau ntawm qhov ntsuas
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
Yuav ua li cas koj thiaj paub yog hais tias ib tug scatter plot tsis muaj zog los yog muaj zog?
Peb hais tias muaj kev sib raug zoo tsis zoo nyob nruab nrab ntawm qhov sib txawv x thiab y. Xav txog cov nram qab no scatterplot: Peb saib tias y nce li x nce, thiab cov ntsiab lus tsis nyob ntawm txoj kab ncaj nraim. Peb hais tias ib qho kev sib raug zoo tsis muaj zog muaj nyob nruab nrab ntawm qhov sib txawv x thiab y
