Yog ob qhov ntau proportional , ces lawv muaj ib tug tsis tu ncua ratio. Yog qhov ratio tsis yog tas li, ob qhov ntau tau hais tias yog tsis yog - proportional . Peb yuav ua cov ntxhuav thiab saib cov kev sib raug zoo ntawm cov variables los txiav txim proportionality.
Ib yam li ntawd, tib neeg nug, lub ntsiab lus ntawm kev tsis sib haum xeeb yog dab tsi?
Graph ntawm a tsis yog - proportional linear kev sib raug zoo yog ib txoj kab uas tsis hla los ntawm lub hauv paus chiv keeb, whereas cov duab ntawm a proportional linear kev sib raug zoo yog ib txoj kab uas hla los ntawm lub hauv paus chiv keeb.
Ib tug kuj yuav nug, ua li cas koj paub yog hais tias nws yog ib tug proportional kev sib raug zoo? Piv txwv li proportional yog lawv sawv cev tib yam kev sib raug zoo . Ib txoj kev pom yog ob qho piv txwv yog proportional yog sau lawv ua feem thiab ces txo lawv. Yog qhov txo qis yog tib yam, koj qhov piv txwv yog proportional . Txhawm rau pom cov txheej txheem no hauv kev nqis tes ua, kuaj tawm ntawm no nyeem!
Tsis tas li ntawd, qhov piv txwv ntawm kev sib raug zoo yog dab tsi?
A proportional kev sib raug zoo yog hais tias lawv yog tib yam. Rau piv txwv , 1/2 thiab 6/12 muaj a proportional kev sib raug zoo , uas txhais tau tias lawv yog tib yam.
Yuav ua li cas koj thiaj paub tias kev sib raug zoo yog proportional lossis Nonproportional?
Sib npaug functions yuav nyob rau hauv daim ntawv y = kx thiab tsis sib npaug functions yuav nyob rau hauv daim ntawv y = mx + b. Cov tub ntxhais kawm yuav tsum txiav txim siab seb qhov haujlwm puas yog proportional los yog tsis sib npaug nyob rau hauv kev ua lej los yog lub ntiaj teb tiag tiag.

Dab tsi yog proportional ncaj qha rau nruab nrab kinetic zog?
Qhov nruab nrab kinetic zog ntawm ib qho kev sau ntawm cov pa roj yog ncaj qha proportional rau qhov kub thiab txias nkaus xwb
Dab tsi yog proportional linear kev sib raug zoo?
Proportional thiab linear functions yuav luag zoo tib yam nyob rau hauv daim ntawv. Qhov txawv tsuas yog qhov sib ntxiv ntawm qhov "b" tas mus li rau txoj haujlwm linear. Qhov tseeb, kev sib raug zoo ntawm kev sib raug zoo tsuas yog ib qho kev sib raug zoo uas b = 0, lossis muab tso rau lwm txoj hauv kev, qhov twg kab hla dhau los ntawm keeb kwm (0,0)
Dab tsi yog proportional ncaj qha rau zaus?
Lub teeb tuaj yeem xav tias yog "particle" ntawm electromagnetic zog hu ua photons. Txij li thaum lub zog nce raws li qhov zaus nce, lub zog yog ncaj qha proportional rau qhov zaus. Vim tias zaus thiab wavelength muaj feem cuam tshuam los ntawm qhov tsis tu ncua (c) lub zog kuj tuaj yeem sau rau hauv cov ntsiab lus ntawm wavelength: E = h · c / λ
Lub ntsiab txhais ntawm proportional kev sib raug zoo hauv lej yog dab tsi?
Kev sib raug zoo. (Qee cov phau ntawv piav qhia txog kev sib raug zoo los ntawm kev hais tias 'y sib txawv nrog x' lossis qhov 'y yog ncaj qha proportional rau x.') Qhov no txhais tau hais tias thaum x nce, y nce thiab x qis, y txo qis-thiab qhov piv txwv. nruab nrab ntawm lawv ib txwm nyob tib yam
Dab tsi yog qhov sib txawv ntawm qhov proportional thiab Nonproportional kev sib raug zoo?
Proportional: Yuav ua li cas qhia qhov txawv: Daim duab proportional yog ib txoj kab ncaj nraim uas ib txwm mus dhau ntawm keeb kwm. Ib daim duab tsis sib npaug yog ib txoj kab ncaj nraim uas tsis dhau los ntawm lub hauv paus chiv keeb
