Qhov hnyav yog ib qho kev ntsuas ntawm lub zog ntawm lub ntiajteb txawj nqus ua rau ib yam khoom. Raws li rau Newton txoj cai ntawm kev txav, quab yuam yog ncaj qha proportional rau ob leeg huab hwm coj thiab acceleration , thiab qhov sib npaug ntawm lub zog yog F = m * a, qhov twg m = pawg thiab ib = kev ceev.
Tsis tas li ntawd, kev sib raug zoo ntawm huab hwm coj thiab acceleration yog dab tsi?
A: Cov kev sib raug zoo ntawm huab hwm coj thiab acceleration tau piav nyob rau hauv Newton's Second Law of Motion. Nws Txoj Cai Thib Ob hais tias ntau dua pawg ib qho khoom muaj, ntau lub zog yog tsim nyog rau nws kom nrawm.
puas loj thiab acceleration muaj kev sib raug zoo? Newton txoj cai thib ob ntawm tsab ntawv tsa suab hais tias kev ceev ntawm ib yam khoom sib npaug ntawm lub zog ua haujlwm ntawm cov khoom faib los ntawm cov khoom pawg . Raws li txoj cai thib ob, muaj a kev sib raug zoo nruab nrab ntawm lub zog thiab kev ceev thiab inverse kev sib raug zoo nruab nrab huab hwm coj thiab acceleration.
Ib yam li ntawd, nws tau nug, puas yog qhov hnyav hloov nrog acceleration?
Cov " hnyav "ntawm ib yam khoom raws li lub ntsiab lus ntawm "mass * gravity" txhais tau hais tias cov hnyav ntawm ib yam khoom ua tsis yog hloov thaum ceev . Koj hnyav nce nrog qhov zoo kev ceev thiab koj hnyav txo qis nrog qhov tsis zoo kev ceev.
Formula yog dab tsi?
Cov qauv rau zog hais zog yog sib npaug rau qhov loj (m) multiplied by acceleration (a). quab yuam ntsuas hauv Newtons (N), qhov hnyav hauv kilograms (kg), thiab acceleration hauv meters ib ob squared (m / s2).

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
Nws txhais li cas thaum kev sib raug zoo ntawm kev sib raug zoo ua kev cuam tshuam?
Kev sib raug zoo ntawm ob tus neeg uas txhua tus neeg nyob ntawm thiab tau txais kev txhawb zog, txawm tias muaj txiaj ntsig lossis kev puas tsuaj, los ntawm lwm tus. ib qho kev sib cuam tshuam lossis kev sib raug zoo ntawm ob tus neeg, pab pawg, thiab lwm yam
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Kev sib raug zoo ntawm lub zog thiab kev nrawm yog dab tsi?
Newton txoj cai thib ob ntawm kev txav mus los piav txog kev sib raug zoo ntawm kev quab yuam thiab kev nrawm. Lawv ncaj qha proportional. Yog tias koj nce lub zog siv rau ib qho khoom, qhov acceleration ntawm cov khoom ntawd nce los ntawm tib yam. Nyob rau hauv luv luv, quab yuam sib npaug loj lub sij hawm acceleration
Dab tsi yog qhov kev sib raug zoo ntawm kev ua lej ntawm qhov kev nyuaj siab khov kho thiab Mollality?
Kev nyuaj siab qhov chaw khov kho yog cov cuab yeej sib koom ua ke pom hauv cov kev daws teeb meem uas tshwm sim los ntawm kev qhia txog cov kuab tshuaj molecules rau cov kuab tshuaj. Cov ntsiab lus khov ntawm cov kev daws yog tag nrho qis dua li cov kuab tshuaj ntshiab thiab yog ncaj qha proportional rau molality ntawm cov kuab tshuaj
