Tshwj xeeb Relativity hais tias 1 kg ib * (y-1) * c^2, qhov twg y (lorentz gamma factor) yog qhov ua haujlwm ntawm qhov nrawm uas, ntawm v = 30 m / s, yog li 1.00000000000000050069252. Yog li cov kinetic zog ntawm koj pob yog 450.0000000000034 J.
Ntawm no, kinetic zog formula yog dab tsi?
Cov mis rau xam lub zog kinetic (KE) yog KE = 0.5 x mv2. Ntawm no m sawv rau pawg , qhov ntsuas ntawm qhov teeb meem ntau npaum li cas hauv ib qho khoom, thiab v sawv rau nrawm ntawm qhov khoom, lossis tus nqi ntawm qhov khoom hloov nws txoj haujlwm.
Tsis tas li ntawd, koj yuav nrhiav tau lub zog kinetic ntawm ib qho hluav taws xob li cas? Re: Kinetic Zog ntawm Hluav taws xob [TSHIAB] Yog li ntawd, peb xam tus kinetic zog siv cov kev sib npaug E(photon) = E(threshold) + KE. Tom qab ntawd, peb tuaj yeem siv lub kev sib npaug rau kinetic zog (KE = 1/2 mv2) thiab hloov nyob rau hauv qhov loj ntawm ib hluav taws xob (9.11 x 10-31 kg), peb tuaj yeem ua tau xam lub nrawm rau ib leeg hluav taws xob.
Ib yam li ntawd, nws raug nug, lub zog kinetic ntawm 3 kilogram pob yog dab tsi?
Dab tsi yog kinetic zog ntawm 3 - kg pob uas yog dov ntawm 2 meters ib ob? 3.2 KE = amrz = 2 x 3 ka = 65 3 . Lub peev xwm zog ntawm ib qho appte yog 6.00 joules.
Vim li cas kinetic zog ntawm ib yam khoom txhais li 1 2mv2?
Yog li ntawd, qhov kev ncua deb yog nce sai dua qhov kev tshaj tawm. Uas ua rau lub sij hawm squared nyob rau hauv. Txawm li cas los lub khoom tsis tau mus uas ceev rau tag nrho lub sij hawm, qhov nruab nrab tshaj tawm tsuas yog ib nrab (nws pib ntawm xoom). Uas muab cov 1 / 2 lub sij hawm.

Lub zog kinetic ntawm lub rotating log yog dab tsi?
Ib qho khoom tig kuj muaj lub zog kinetic. Thaum ib yam khoom tig los ntawm nws qhov nruab nrab ntawm qhov loj, nws lub zog kinetic rotational yog K = ½ I ω 2. Rotational kinetic zog = ½ lub sij hawm ntawm inertia * (angular ceev) 2. Thaum lub angular tshaj tawm ntawm lub log tig ob npaug, nws lub zog kinetic nce los ntawm ib qho ntawm plaub
Dab tsi yog kev sib raug zoo ntawm gravitational muaj peev xwm zog thiab kinetic zog?
Thaum ib yam khoom ntog, nws lub peev xwm gravitational hloov mus rau kinetic zog. Koj tuaj yeem siv qhov kev sib raug zoo no los xam qhov ceev ntawm qhov khoom qhovntsej thiaj tsis mob. Gravitational muaj peev xwm zog rau ib pawg m ntawm qhov siab h nyob ze ntawm lub ntiaj teb yog mgh ntau tshaj li lub zog muaj peev xwm yuav nyob rau qhov siab 0
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog qhov txawv ntawm lub zog siv zog thiab lub zog thauj khoom?
Raws li nrog cov dav hlau inclined, cov khoom yuav tsum tau txav mus los yog lub zog muaj zog los yog thauj khoom thiab kev siv zog yog lub zog muab tso rau hauv kev txav mus los ntawm lwm qhov kawg ntawm lub fulcrum
Dab tsi yog cov qauv ntawm lub zog nyob rau hauv lub peev xwm thiab lub zog kinetic?
Lub zog muaj peev xwm yog khaws cia lub zog thiab lub zog ntawm txoj haujlwm - lub zog gravitational. Muaj ntau hom kev muaj peev xwm muaj zog. Kinetic zog yog kev txav - ntawm nthwv dej, electrons, atoms, molecules, tshuaj, thiab khoom. Chemical Zog yog lub zog khaws cia hauv cov khoom sib txuas ntawm atoms thiab molecules
