Raws li Newton s Txoj Cai thib ob ntawm Motion, thiab paub raws li cov Txoj cai ntawm Force thiab Acceleration, ib tug quab yuam raws li ib tug khoom ua rau nws mus ceev raws li lub formula net force = mass x acceleration. Yog li qhov acceleration ntawm cov khoom yog ncaj qha proportional rau lub zog thiab inversely proportional rau qhov loj.
Tom qab ntawd, ib tug kuj yuav nug, Newton txoj cai thib 2 yog dab tsi?
Newton txoj cai thib ob ntawm kev txav muaj feem xyuam rau tus cwj pwm ntawm cov khoom uas tag nrho cov rog uas twb muaj lawm tsis sib npaug. Cov ob txoj cai hais tias qhov acceleration ntawm ib yam khoom yog nyob ntawm ob qhov sib txawv - lub net quab yuam ua raws li cov khoom thiab qhov loj ntawm cov khoom.
Qhov thib ob, tus qauv siv rau Newton txoj cai thib ob ntawm kev txav yog dab tsi? Hauv kev sib npaug daim ntawv, Newton txoj cai thib ob ntawm kev txav yog a = Fnetm a = F net m. Qhov no feem ntau sau rau hauv daim ntawv paub ntau dua: Fnet = mas. Qhov hnyav w ntawm ib yam khoom yog txhais tau tias yog lub zog ntawm lub ntiajteb txawj nqus ua rau ib qho khoom loj m.
Ib sab ntawm no, vim li cas Newton txoj cai thib ob tseem ceeb?
Newton Txoj Cai Thib Ob ntawm Motion F = ma yog heev tseem ceeb vim nws qhia txog kev sib raug zoo ntawm lub zog thiab kev txav. Nws tso cai rau koj los xam cov acceleration (thiab yog li ntawd tshaj tawm thiab txoj hauj lwm) ntawm ib yam khoom uas paub rog. Qhov no yog qhov tseem ceeb heev rau cov kws tshawb fawb, engineers, inventors, thiab lwm yam.
Newton's 3 txoj cai yog dab tsi?
Lub zog yog lub laub lossis rub uas ua rau ib yam khoom raws li qhov tshwm sim ntawm nws qhov kev cuam tshuam nrog lwm yam khoom. Ob lub zog no yog hu ua kev ua thiab cov tshuaj tiv thaiv thiab yog cov ntsiab lus ntawm Newton txoj cai thib peb ntawm kev tawm suab. Raws li hais, Newton txoj cai thib peb yog: Rau txhua qhov kev ua, muaj qhov sib npaug thiab tawm tsam.

Newton txoj cai thib ob hauv cov ntsiab lus yooj yim yog dab tsi?
Newton txoj cai thib ob hais tias kev nrawm ntawm ib qho yog nyob ntawm lub zog ua raws li cov khoom thiab cov khoom 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
Dab tsi yog qhov txawv ntawm txoj cai khoom thiab txoj cai saw?
Peb siv txoj cai saw thaum sib txawv ntawm 'kev ua haujlwm ntawm kev ua haujlwm', zoo li f(g(x)) feem ntau. Peb siv txoj cai khoom thaum sib txawv ntawm ob txoj haujlwm sib npaug ua ke, zoo li f(x)g(x) feem ntau. Tab sis nco ntsoov lawv yog cov haujlwm cais: ib tus tsis vam khom rau cov lus teb rau lwm tus
Qhov piv txwv zoo tshaj ntawm Newton txoj cai thib peb ntawm kev txav yog dab tsi?
Taug kev: thaum koj taug kev, koj thawb txoj kev xws li koj siv lub zog ntawm txoj kev thiab lub zog tawm tsam txav koj mus tom ntej. Phom Phom: Thaum ib tug neeg tua phom, cov tshuaj tiv thaiv quab yuam thawb rab phom rov qab. Dhia mus rau hauv av los ntawm lub nkoj: Lub zog quab yuam thov rau ntawm lub nkoj thiab cov tshuaj tiv thaiv quab yuam thawb koj mus rau hauv av
Hund txoj cai thiab Pauli cais txoj cai nrog piv txwv yog dab tsi?
Hund's Rule hais tias yog 2 lossis ntau dua degenerate (piv txwv li tib lub zog) orbitals muaj, ib qho hluav taws xob nkag mus rau hauv ib qho kom txog thaum tag nrho lawv ib nrab puv ua ntej ua ke. ThePauli Exclusion Principle hais tias tsis muaj ob lub tshuab hluav taws xob tuaj yeem txheeb xyuas tau los ntawm tib pawg ntawm quantum tooj
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
