Pseudo Force vs Centrifugal Force

Pseudo quab yuam thiab centrifugal quab yuam yog ob qhov xwm txheej uas tshwm sim hauv kev kawm txog kev siv tshuab. Cov ntawv sau meej meej, cov no yog cov xwm txheej lossis cov ntsiab lus zoo siv hauv kev kawm ntawm cov ntawv tsis yog inertial. Nws yog ib qho tseem ceeb kom muaj kev nkag siab zoo nyob rau hauv ob qho tib si, pseudo thiab centrifugal rog, thiaj li yuav muaj kev nkag siab zoo nyob rau hauv classical mechanics ntawm lub cev muaj lub voj voog. Cov kev xav ntawm pseudo quab yuam thiab centripetal quab yuam tuaj yeem muaj txiaj ntsig zoo hauv thaj chaw xws li physics, automobile engineering, machinery, space science, astrophysics, and even relativity. Hauv tsab xov xwm no, peb yuav tham txog dab tsi pseudo quab yuam yog dab tsi thiab lub zog centrifugal yog dab tsi, lawv cov ntawv thov hauv ntau yam, qhov sib xws thiab thaum kawg lawv qhov sib txawv.

Pseudo Force

Lo lus pseudo txhais tias dag lossis dag, txhais tau tias ua txuj ua ib yam dab tsi, uas nws tsis yog. Pseudo quab yuam tsis yog lub zog; peb yuav pom dab tsi pseudo quab yuam tiag tiag nyob rau hauv seem no. Pseudo quab yuam yog paub nyob rau hauv ntau lub npe, xws li dag dag zog, d'Alembert quab yuam, los yog inertial quab yuam. Cov qauv ntawm pseudo quab yuam no tsuas yog yuav tsum tau nyob rau hauv cov ntaub ntawv uas tsis yog inertial ntawm kev siv. Ib qho inertial thav duab, yog ib lub thav duab (ib txheej ntawm kev sib koom tes) uas tsis txav mus los, lossis txav ntawm qhov nrawm nrawm. Yog li ntawd, ib tug non-inertial thav duab yog ib txheej ntawm coordinates, uas yog txav nrog acceleration. Lub ntiaj teb yog ib tug piv txwv zoo rau ib tug tsis-inertial ncej. Lub zog pseudo yog ib lub zog uas txhais los piav txog qhov nrawm ntawm lub cev nyob rau hauv ib qho uas tsis yog-inertial thav duab txheeb ze rau ib qho inertial ncej. Txij li tag nrho cov Newtonian thiab classical mechanics equations raug txhais rau ib qho inertial thav duab, nws yog ib qho tsim nyog yuav tau ntxiv lub zog pseudo txhawm rau ua kom suav tau. Muaj plaub yam pseudo rog. Cov no yog txhais rau cov xwm txheej hauv qab no. Rau cov txheeb ze acceleration ntawm ib txoj kab ncaj nraim, muaj lub zog rectilinear. Rau acceleration vim kev sib hloov, muaj zog centrifugal thiab Coriolis quab yuam. Rau qhov xwm txheej ntawm kev sib hloov pauv, muaj Euler quab yuam. Nws yog ib qho tseem ceeb kom nkag siab tias cov rog no tsis yog lub zog tiag tiag. Lawv tau tsim cov ntsiab lus, uas ua rau kev suav yooj yim dua. Cov rog no tau qhia kom qhov inertial acceleration ntawm lub cev tuaj yeem suav nrog, hauv kev suav.

Centrifugal Force

Centrifugal quab yuam kuj yog ib daim ntawv ntawm lub zog pseudo. Txhua yam khoom rotating muaj lub zog centripetal ua yeeb yam yog ib qho kev taw qhia radially sab nraud ntawm qhov chaw ntawm kev sib hloov. Txawm li cas los xij, lub zog centrifugal tsis yog lub cev quab yuam ua rau lub cev, nws yog lub tswv yim tsim los kom yooj yim ntawm kev suav. Lub zog tiag tiag ua rau lub zog tig yog qhov tseeb ntawm qhov chaw, thiab nws yog hu ua lub zog centripetal. Lub zog centrifugal yog lwm txoj hauv kev ntxiv lub zog ntawm lub cev rau kev suav. Nws kuj tseem suav tias yog lub zog reactive rau lub zog centripetal. Thaum lub zog centripetal raug tshem tawm lub centrifugal quab yuam kuj dhau los ua xoom.

Qhov txawv ntawm Pseudo Force thiab Centrifugal Force yog dab tsi?

• Lub zog centrifugal yog qhov tshwj xeeb ntawm pseudo quab yuam.

• Thaum lub zog centrifugal tshwm sim tsuas yog hauv cov tshuab tig, pseudo rog tshwm sim nyob rau hauv ib qho uas tsis yog-inertial system.
