Zoo Siab yog txhais raws li ' quab yuam ib cheeb tsam ib cheeb tsam'-- Siab = zog / cheeb tsam. Yog li, obviously, quab yuam thiab Siab muaj feem cuam tshuam, i.e., quab yuam yog ncaj qha proportional rau Siab , uas txhais tau tias, ntau zog koj thov raws li qhov chaw ruaj, ntau dua siab koj tsim.
Ib yam li ntawd, lub zog thiab kev quab yuam cuam tshuam li cas?
Siab thiab quab yuam yog ntsig txog , thiab yog li koj tuaj yeem suav ib qho yog tias koj paub lwm tus los ntawm kev siv physics kab zauv, P = F / A. Vim siab yog zog muab faib los ntawm cheeb tsam, nws meter-kilogram-thib ob (MKS) units yog newtons ib square meter, los yog N / m2.
Tsis tas li ntawd, kev sib raug zoo ntawm thaj chaw saum npoo thiab qhov siab yog dab tsi? Cov siab exerted rau a nto los ntawm ib qho khoom nce raws li qhov hnyav ntawm qhov khoom nce los yog qhov thaj chaw saum npoo ntawm kev sib cuag txo. Xwb lub siab exerted txo qis raws li qhov hnyav ntawm cov khoom txo qis los yog thaj chaw saum npoo ntawm kev sib cuag nce.
Kuj Paub, qhov kev sib raug zoo ntawm lub zog thiab kev sib cuam tshuam yog dab tsi?
A zog yog lub laub lossis rub rau ntawm qhov khoom uas tshwm sim los ntawm qhov khoom kev sib tham nrog rau lwm yam khoom. Thaum twg muaj ib qho kev sib cuam tshuam ntawm ob yam khoom, muaj ib zog ntawm txhua yam khoom. Thaum lub kev sib tham ceased, ob yam khoom tsis muaj kev zog.
Tus qauv ntawm lub siab yog dab tsi?
Cov formula ntawm siab yog quab yuam muab faib los ntawm cheeb tsam ntawm qhov chaw ntawm qhov chaw ntawm kev sib cuag. Siab yog lub zog ib chav tsev siv nyob rau hauv ib txoj kev perpendicular mus rau saum npoo ntawm ib yam khoom. Nws yog ib tug scalar ntau denoted los ntawm lub cim p.
Pom zoo:
Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm kinetic thiab lub zog muaj peev xwm?
Lub Zog Muaj Peev Xwm yog lub zog khaws cia hauv ib qho khoom lossis qhov system vim nws txoj haujlwm lossis kev teeb tsa. Kinetic zog ntawm ib yam khoom yog txheeb ze rau lwm yam khoom txav thiab nyob ruaj ruaj hauv nws qhov chaw tam sim ntawd
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
