FB . Lus Nug: Kev taw qhia ntawm Magnetic Force.
Ib yam li ntawd, tej zaum koj yuav nug, dab tsi yog lub zog sib nqus hauv cov lus yooj yim?
Sib nqus quab yuam , attraction los yog repulsion uas tshwm sim ntawm hluav taws xob nqi hais vim lawv cov lus tsa suab. Nws yog qhov yooj yim zog lub luag haujlwm rau cov teebmeem xws li kev ua haujlwm ntawm lub tshuab hluav taws xob thiab kev nyiam ntawm cov hlau nplaum rau hlau.
Tsis tas li ntawd, electromagnetism physics yog dab tsi? Electromagnetism yog ib ceg ntawm physics koom nrog kev kawm ntawm cov electromagnetic quab yuam, ib hom kev cuam tshuam ntawm lub cev uas tshwm sim ntawm cov khoom siv hluav taws xob.
Ib yam li ntawd, nws nug, F qvB sawv cev rau dab tsi?
Magnetic Force 1. Lub zog yog perpendicular rau ob qho tib si lub nrawm v ntawm tus nqi q thiab magnetic teb B. Qhov loj ntawm lub zog yog F = qvB sin θ qhov twg yog cov lub kaum sab xis <180 degrees ntawm qhov nrawm thiab qhov sib nqus.
Puas yog kev ua haujlwm ua los ntawm cov hlau nplaum ib txwm xoom?
Sib nqus tsis muaj zog (net) ua haujlwm . Vim lub Sib nqus lub zog ntawm tus nqi txav yog perpendicular rau qhov nrawm, lub ua haujlwm los ntawm a Sib nqus zog yog xoom . Lub kauj ntawm sab laug ua rau a magnetic teb mus rau sab xis.

U txhais li cas hauv physics tshaj tawm?
U yog pib tshaj tawm hauv m / s. t yog time ins. Piv txwv li, lub tsheb nrawm hauv 5 s ntawm 25 m / s txog 3 5 m / s. Nws nrawm hloov los ntawm 35 - 25 = 10 m / s
Qhov sib npaug txhais li cas hauv physics?
Kev sib npaug. Ib qho xwm txheej uas txhua tus cuam tshuam kev ua yeeb yam tso tseg ib leeg, kom qhov xwm txheej zoo li qub lossis sib npaug. Hauv physics, equilibrium tshwm sim los ntawm kev tshem tawm cov rog ua rau ntawm ib qho khoom
Lub angular txhais li cas hauv physics?
Npe. muaj kaum los yog kaum. ntawm, ntsig txog, lossis ntsuas los ntawm lub kaum sab xis. Physics. hais txog qhov muaj feem cuam tshuam nrog lub cev hloov pauv uas ntsuas nyob rau hauv kev siv rau nws axis ntawm kiv puag ncig
Cov ntawv Greek Psi txhais li cas hauv physics?
Tsab ntawv psi feem ntau siv hauv physics los sawv cev yoj ua haujlwm hauv quantum mechanics, xws li hauv Schrödinger equation thiab bra-ket notation:. Nws kuj yog siv los sawv cev rau (generalized) positional states of a qubit in a quantum computer
Nws txhais li cas thaum lub system nyob rau hauv equilibrium physics?
Raws li OED, lo lus equilibrium txhais tau tias '1. a Nyob rau hauv lub cev kev xav: Cov xwm txheej ntawm kev sib npaug sib npaug ntawm cov tawm tsam rog; uas lub xeev ntawm cov khoom siv nyob rau hauv uas cov rog ua raws li qhov system, los yog cov ntawm lawv cov uas tau muab rau hauv kev txiav txim siab, yog li txheej txheem uas lawv cov txiaj ntsig ntawm txhua qhov yog xoom
