Raws li qhov kev ncua deb nyob rau hauv physics? nthuav piv txwv

Lub ntsiab yog mob siab rau cov menyuam kawm ntawv uas muaj tsuas yog tus thawj xyoo ntawm physics. Ntawm no yog peb tham tsis tau tsuas yog hais txog yuav ua li cas qhov kev ncua deb nyob rau hauv physics, tab sis kuj hais txog lwm yam nthuav tej yam. Cia qhov no tshaj plaws yuav txaus siab rau tag nrho cov seem thiab xai.

Yuav ua li cas yog nws - qhov kev ncua deb?

Nyob rau hauv physics, txhua txhua lub cev kom muaj nuj nqis nws muaj nws tus kheej lub cim (los yog Latin, los yog Greek tsab ntawv). Tag nrho cov no yog ua li cas nyob rau hauv thiaj li yuav ua rau nws yooj yim dua thiab tsis txhob tsis meej pem. Pom zoo yuav raug lim ua thaum uas sau ntawv tau ib phau ntawv txog tej nqe lus: deb = tshaj tawm x lub sij hawm. Ib tug physics heev muaj ntau ntau cov qauv nrog ib tug plurality ntawm tsis. Thiab kuj muaj kev square thiab nyhav qhov tseem ceeb. Yog li ntawd dab tsi yog qhov ntawv qhia qhov kev ncua deb nyob rau hauv physics? Tam sim ntawd qhia kom meej hais tias muaj ob hom ntawm cov cim li qhov kev ncua deb thiab qhov ntev yog tus loj tib yam thiab tib chav tsev. Yog li ntawd, «S» - qhov no yog qhov cim. Yuav kom tau raws li ib tug tsab ntawv nyob rau hauv lub puzzle, los yog cov qauv ntawm seem "Txhua yam".

Ntseeg kuv, tsis muaj dab tsi nyuab nyob rau hauv kev daws teeb meem. Tab sis raws li ntev raws li koj paub cov lej, thiab muaj lub sij hawm rau nws. Koj yuav tsum tau paub txog kev ua hauj lwm nrog cov zauv feem, Numeracy, qhia nkhaus, daws tau sib npaug. Yog tsis muaj cov kev txawj ntse yuav nyuaj heev nyob rau hauv physics.

Lub neej piv txwv

Yuav ua li cas yog cov kev coj? Raws li qhov kev ncua deb nyob rau hauv physics, peb twb ua ntshiab. Tam sim no cia tus nrog lub tswvyim.

Xav txog tej yam uas koj yuav sawv nyob rau hauv pem hauv ntej ntawm nws lub tsev. Koj ua hauj lwm - mus rau lub tsev kawm ntawv. Txoj kev yeej ib txwm ncaj. Yuav kom mus ntawm lub zog li ob nas this. Los ntawm lub qhov rooj ntawm lub nkag mus rau lub tsev kawm ntawv qhov rooj 200 meters. Qhov no yog qhov kev ncua deb. Yuav ua li cas yuav qhov kev piav qhia ntawm koj taug kev los ntawm lub tsev mus rau lub tsev kawm ntawv?

S = 200 m.

Yog vim li cas tsis yog peb sau ntawv "m", thiab tsuas yog tas rau tsab ntawv? Vim hais tias ntawm no nws yog lub abbreviated tsab ntawv los. Ib me ntsis tom qab, thiab ntsib nrog rau lwm cov tsis hais tias yog txuam nrog rau kev ncua deb.

Tam sim no xav txog tej yam uas txoj kev ntawm lub tsev khaws cov tortuous. Yog hais tias koj saib nyob rau ib daim ntawv qhia txog cheeb tsam koj nyob, koj yuav pom tau tias qhov kev ncua deb yog tib yam li ua ntej tsev kawm ntawv mus kav los ntawm tsev. Tab sis yog vim li cas xws li ib tug ntev txoj kev? Vim hais tias txoj kev no tsis ncaj. Peb yuav tsum tsiv mus nyob rau ntawm lub tsheb teeb, tau ib tug lossis loj lub tsev thiab cia li muaj koj tau mus rau lub khw. Nyob rau hauv cov ntaub ntawv no, lub sij deb yog ntau dua. Lub ntsuas thiab physics, qhov no qhia ib tug "nkhaus txoj kev." Ib tug ncaj kab - nws yog ib cov ntshiab deb, yog li taug kev los ntawm ib lub phab ntsa ntawm lub tsev loj. Peb kuj muab rau koj ib qho piv txwv, thiab ib tug txiv neej uas mus ua hauj lwm.

Muaj dab tsi deb?

Cov kev xav ntawm "deb" yuav tsis muaj nyob ntawm nws tus kheej, nws yuav tsum ua si ib lub luag hauj lwm. Piv txwv li, koj caij ib lub tsheb tuam tsev kawm ntawv thiab tsis txhob mus rau ko taw, vim hais tias lig lawm. Raws li peb hais ua ntej lawm, nyob rau peb txoj kev mus ncaj rau lub tsev kawm ntawv. Koj yuav xyuam xim caij ntawm tus ciav. Ntawm cov hoob kawm, yog tias koj next rau ko taw, koj tau ntev tshaj li ua txoj kev cycling. Yuav ua li cas yog qhov teeb meem no? Qhov no, ntawm chav kawm, sib tham txog cov kev ceev uas cov txav. Tom qab ntawd peb yuav pom tus qauv uas pab, yuav ua li cas nrhiav tau qhov kev ncua deb. Physics - yog ib tug science, uas muaj ib yam dab tsi los xam. Pom zoo, nws yog nthuav cia li ceev npaum li cas koj caij ib lub tsheb tuam? Yog hais tias koj paub qhov kev ncua deb mus rau lub tsev kawm ntawv thiab cov kev khiav tawm, koj yuav nrhiav tau thiab cov kev ceev.

Yog li ntawd, peb muaj ob tug lwm cov kev xaiv:

t - lub sij hawm,

v - tshaj tawm.

Txhua yam yuav ntau npaum li cas nthuav yog tias koj kawm ua hauj lwm nrog cov qauv thiab nrhiav tau cov tsis paub hais tias los ntawm kev siv cov zauv feem. Nco qab kom sai li sai raws li cov kev cai ntawm kev kawm txog zauv: tag nrho cov uas yog tom ntej no mus rau lub tsis paub hais tias, nws yog nyob rau hauv lub denominator (ie, cov zauv down). Piv txwv li, qhov kev ncua deb mis (Physics) - ib cov khoom ntawm lub sij hawm thiab ceev. Thiab nyob rau hauv lwm tus neeg mob - ib feem. Ntsia hauv daim duab, uas qhia tau hais tias yuav ua li cas nrhiav tau qhov kev ncua deb, ceev thiab lub sij hawm. Tau yuav kawm thiab to taub li cas xws li cov qauv yog tau. Tag nrho yuav tsum tau tsuas yog los ntawm cov kev cai ntawm kev kawm txog zauv, yees tsis muaj dab tsi nyob rau hauv cov qauv no ua tsis tau. Wb peb xyaum (tsis zoo): Yuav ua li cas daim ntawv qhia cov kev coj hauv physics?

Yuav ua li cas yog ntsuas?

Hopefully, koj nco ntsoov txoj kev xaiv qhov yooj yim ntau, lawv los. Nws yog lub sij hawm mus kawm cov chav nyob ntawm kev ntsuas. Muaj tseem yuav tau cob qhia koj nco, nco ntsoov. Nws yog ib qho tseem ceeb kom paub tias tsis tau tsuas yog yuav ua li cas qhov kev ncua deb nyob rau hauv physics, tab sis kuj lub sij hawm, ceev. Tab sis qhov no tsuas yog ib tug me me qhov teeb meem. Tom ntej no nws yuav muaj ntau nyuaj. Cia peb pib:

S - qhov kev ncua deb - m, km [m] [km];

v - ceev - meters ib ob, kilometers moos [m / s], [km / h] (nyob rau hauv cov ntaub ntawv ntawm qhov chaw velocities yuav tsum muaj ntaub ntawv kilometer ib ob;

t - lub sij hawm - thib ob, feeb, teev [c] [min] [h].

Daim ntawv ceeb toom yuav ua li cas cov hoob ceev. Kom raug, feem. Tam sim no xav txog tej yam uas nyob ntawm no: S / t = m / los yog S / t = km / h. Qhov ntawd yog qhov chaw uas muaj raug tua. Nyob rau hauv lub thoob ntiaj teb system ntawm chav nyob SI qhov tseem ceeb ntawm cov tsis muaj ib tug 'meter', thib ob, meters ib ob.

Peb figured tawm yuav ua li cas qhov kev ncua deb nyob rau hauv physics, suav hais tias lub sij hawm thiab ceev, uas yog inseparably txuas rau nws.
