Newton txoj cai thib ob hais tias acceleration ntawm ib tug particle yog nyob ntawm lub zog ua raws li qhov particle thiab particle qhov loj. Rau ib tug muab particle, yog hais tias lub net quab yuam yog nce, lub acceleration yog nce. Rau ib tug muab net quab yuam, qhov ntau npaum li cas ib tug particle muaj, qhov tsawg acceleration nws muaj.
Hauv qhov no, Newton txoj cai thib 2 yog dab tsi?
Newton txoj cai thib ob ntawm kev txav hais txog tus cwj pwm ntawm cov khoom uas tag nrho cov zog uas twb muaj lawm tsis sib npaug. Cov ob txoj cai hais tias qhov acceleration ntawm ib yam khoom yog nyob ntawm ob yam sib txawv - lub net force ua raws li cov khoom thiab qhov loj ntawm cov khoom.
Tom qab ntawd, lo lus nug yog, Newton's 3 txoj cai lij choj yog dab tsi? Cov kev cai yog: (1) Txhua yam khoom txav mus rau hauv txoj kab ncaj nraim tshwj tsis yog ua los ntawm lub zog. (2) Lub acceleration ntawm ib yam khoom yog ncaj qha proportional rau net quab yuam exerted thiab inversely proportional rau cov khoom loj. ( 3 ) Rau txhua qhov kev ua, muaj qhov sib npaug thiab tawm tsam.
Ib yam li ntawd, koj tuaj yeem nug, Newton's 2nd Law of Motion piv txwv yog dab tsi?
Yog tias koj siv tib lub zog los thawb lub tsheb thiab thawb lub tsheb, lub tsheb yuav muaj kev nrawm dua li lub tsheb thauj khoom, vim tias lub tsheb muaj qhov hnyav dua. ? Nws yooj yim dua rau thawb lub tawb nqa khoom dua li qhov puv puv, vim tias tag nrho lub laub yuav khoom muaj ntau dua li qhov khoob.
3 txoj cai lij choj yog dab tsi?
Qhov thib peb txoj cai hais tias rau txhua qhov kev ua ( zog ) nyob rau hauv cov xwm muaj ib tug sib npaug thiab opposite tshuaj tiv thaiv. Hauv lwm lo lus, yog qhov khoom A exerts a zog ntawm object B, ces object B kuj exerts qhov sib npaug zog ntawm qhov khoom A. Daim ntawv ceeb toom tias qhov zog raug siv los ntawm cov khoom sib txawv.

Txoj cai thib peb ntawm kev hais lus rau cov menyuam yog dab tsi?
Txoj cai thib peb hais tias rau txhua qhov kev ua, muaj qhov sib npaug thiab sib npaug. Qhov no txhais tau hais tias ib txwm muaj ob lub zog uas zoo ib yam. Lub zog no yog nyob rau hauv qhov tseeb opposite direction
Lub teeb hauv cov ntsiab lus yooj yim yog dab tsi?
Lub teeb yog hom zog. Nws yog ib daim ntawv ntawm electromagnetic hluav taws xob ntawm lub wavelength uas tuaj yeem kuaj pom los ntawm tib neeg lub qhov muag. Nws yog ib feem me me ntawm electromagnetic spectrumand hluav taws xob muab tawm los ntawm cov hnub qub zoo li lub hnub. Lub teeb muaj nyob rau hauv cov pob khoom me me hu ua photons. Txhua tus nthwv dej muaj qhov zaus wavelengthor
Lub hauv paus ntsiab lus ntawm staining yooj yim yog dab tsi?
Txoj Cai. Nws lub hauv paus ntsiab lus yog ua raws li lub hauv paus ntsiab lus ntawm kev ua kom pom qhov sib txawv ntawm lub cev thiab nyob ib puag ncig nws, los ntawm kev siv cov xim yooj yim. Ib qho yooj yim zas xim muaj cov chromophore zoo uas nyiam nyiam rau cov khoom tsis zoo ntawm tes thiab cov khoom siv hluav taws xob xws li nucleic acids thiab cov protein
Cov ntsiab lus geometric yooj yim yog dab tsi?
Geometric Terms term definition Perpendicular Line Segments ob kab ntu uas hla mus rau daim duab 90 degree kaum sab xis lub kaum sab xis 90 degree Equilateral daim duab peb sab nrog txhua sab sib npaug thiab tag nrho cov kaum sib npaug Scalene Daim duab peb sab muaj peb sab tsis sib xws thiab cov ces kaum
Newton txoj cai thib 2 rau cov menyuam yog dab tsi?
Txoj cai thib ob hais tias qhov loj dua ntawm ib qho khoom, qhov ntau zog nws yuav siv sij hawm kom ceev cov khoom. Tseem muaj qhov sib npaug uas hais tias Force = huab hwm coj x acceleration lossis F = ma. Qhov no kuj txhais tau hais tias qhov nyuaj koj ncaws pob qhov deb nws yuav mus
