Yuav ua li cas muaj ntau yam centimeters nyob rau hauv ib tug 'meter' - qhov tsim nyog paub nyob rau hauv physics zaj lus qhia

Txhua tus menyuam kawm nyob rau hauv dua lub hoob pib nyob rau hauv physics yog ntsib nrog qhov teeb meem ntawm neeg txhais lus units. Yeej nws yog tsim nyog nyob rau hauv thiaj li yuav zoo daws tau qhov teeb meem, raws li tau zoo raws li hloov siab los ntseeg tso cai muab cov ntaub ntawv nyob rau hauv ib tug ntau yooj yim rau daim ntawv. Siv kev txawj ntse uas yog pab tau nyob rau hauv yuav luag txhua qhov teeb meem no muaj feem xyuam rau physics, yog yuav ua li cas muaj ntau yam centimeters mus rau ib 'meter'. Wb to taub cov ntsiab lus uas.

Nrog lub tswvyim ntawm "centimeter" txhua txhua tus me nyuam yog kev nyuaj siab raws li ib tug me nyuam. Sai li sai tau raws li nws muaj ib tug phau ntawv nyob rau hauv lub thawv, nyob rau hauv kev xyaum nws muaj nrog no tus nqi raws li lub squares uas ua tau cov nplooj ntawv yog tsuas 0,5x0,5 cm. Tom qab ntawd nyob rau hauv kev kawm txog zauv qhia cov me nyuam piav tias ib yam khoom muaj peev xwm yuav ntsuas los ntawm no system unit. Tab sis tej zaum nws yog tsuas tsis yooj yim rau siv vim hais tias lawv yuav tsum xyuas seb qhov tsis muaj loj heev tej khoom. No yog invented los ntawm lwm kom muaj nuj nqis, uas tso cai rau ntau paub qhov luaj li cas ntawm loj yam khoom. Nws yog hais txog ib 'meter'. Los ntawm cov thawj qib, txhua tus me nyuam muaj ib tug notion ntawm yuav ua li cas muaj ntau yam centimeters mus rau ib 'meter'. Nws yog ib qhov yuav tsum muaj kev txawj ntse yog lub hauv paus rau kev daws ntawm ntau lub cev muaj teeb meem.

Yuav kom teb tau cov nqe lus nug txog yuav ua li cas muaj ntau yam centimeters mus rau ib 'meter' yog heev yooj yim - lawv zoo tshaj plaws. Nws yog ntau yam ntxiv nyuaj rau txhais ib yam ntawm cov ntau mus rau lwm yam thaum lawv yog square los yog nyhav ntsuas. Raws li nws yog lub npe hu, hais nyob rau hauv square centimeters square khoom thiab nyhav - volume lub cev. Technology dlaws teeb meem nyob rau hauv physics translation ntsuas units yuav tsum tau ua hauj lwm tawm mus rau automaticity.

Nyob rau hauv feem ntau tus neeg mob, yuav hloov cov ntaub ntawv mus rau hauv ib tug txheej txheem cov ntawv kws siv SI system. Nws yog tsis tau tso cai rau siv centimeters. Nws yog yog li ntawd tsim nyog los paub ntau npaum li cas centimeters mus rau ib 'meter' yuav hloov tus nqi mus rau hauv ib tug haum daim ntawv thiab kom daws tau qhov teeb meem.

Yog li ntawd, peb yuav tsum to taub, yuav ua li cas yuav ua rau nws. 1 m 100 cm square meter -. 'Meter' yog multiplied rau nws tus kheej ib zaug. Nws hloov tawm hais tias nws yog tsim nyog los muab ib puas centimeters thiab ib puas lub sij hawm ntau, yog li ntawd nws thiaj li tseem nyob ib kom muaj nuj nqis sib npaug zos rau yam uas peb tau txais nyob rau hauv lub yav dhau los kauj ruam. Sau lo lus teb 'meter', ntsig txog, yog ib puas centimeters cubed. Qhov no tus nqi yog muab tau los ntawm lub ntsiab cai tib yam. Tam sim no koj pom tias tig meters rau centimeters thiab vice versa yog tsis heev nyuaj.

Qhov no yuav tsum muaj kev txawj ntse yuav tuaj nyob rau hauv muab rau tsis tsuas yog nyob rau physics zaj lus qhia, tiam sis kuj nyob rau hauv lub neej. Ib square Meter, piv txwv li, cov neeg feem ntau ntsib thaum ua kho vaj tse nyob rau hauv lub chav tsev los yog thaum npaj mus yuav ib lub tsev tshiab. Lub cheeb tsam ntawm qhov thiab cov chav yog yeej ib txwm teev siv no tus nqi, li ntawd, nws yog ib qho tseem ceeb kom nkag siab txog nws cov kev hloov tsheb mus rau lwm cov chav nyob. Nws yuav zoo li hais tias xws li ib tug self-qhov tseeb tshwm tag, zoo li yuav ua li cas muaj ntau yam centimeters mus rau ib 'meter', nws yog heev yooj yooj yim thiab me ntsis kev paub. Nyob rau hauv qhov tseeb, peb thov nws ntau zaus tshaj peb ntseeg hais tias. Tam sim no koj tsis tau daig nyob rau hauv yuav ua li cas hloov ib chav tsev mus rau lwm lub, raws li zoo raws li paub cov kev cai los ntawm cov uas qhov no tshwm sim.
