Qhov sib txawv tseem ceeb ntawm electrostatic force thiab gravitational force yog electrostatic force yog qhov txaus nyiam lossis quab yuam ntawm ob yam khoom siv hluav taws xob, hos lub zog gravitational yog qhov attraction ntawm ob yam khoom uas tshwm sim vim qhov cuam tshuam ntawm lub ntiajteb txawj nqus.
Electrostatic quab yuam tuaj yeem piav qhia raws li Coulomb quab yuam lossis Coulomb kev sib cuam tshuam, thiab nws yog qhov txaus nyiam lossis quab yuam ntawm ob yam khoom siv hluav taws xob. Lub zog gravitational tuaj yeem piav raws li lub zog uas ua rau ntawm ib qho khoom vim lub ntiajteb txawj nqus.
Electrostatic Force yog dab tsi?
Electrostatic quab yuam yog qhov txaus nyiam lossis quab yuam ntawm ob yam khoom siv hluav taws xob. Nws tuaj yeem piav qhia tias yog Coulomb quab yuam lossis Coulomb kev sib cuam tshuam. Electrostatics yog ib ceg ntawm electromagnetism uas kawm txog hluav taws xob thaum so. Raws li classical physics, qee cov ntaub ntawv xws li amber tuaj yeem nyiam cov khoom hnyav tom qab txhuam lawv qhov chaw. Lub npe Greek ntawm amber, "electron," tau coj mus rau lub npe "hluav taws xob." Cov phenomena ntawm electrostatics tshwm sim los ntawm lub zog uas hluav taws xob tsub nqi rau ib leeg. Cov rog no tuaj yeem piav qhia siv Coulomb txoj cai. Feem ntau, electrostatically induced rog tsis muaj zog, tab sis qee lub zog electrostatic, xws li lub zog ntawm ib qho hluav taws xob thiab ib qho proton, yog li 36 qhov kev txiav txim ntawm qhov muaj zog dua li lub zog gravitational ua ntawm cov subatomic particles.
Daim duab 01: Electrostatic Force Ntawm Cov plaub hau thiab Balloon
Peb tuaj yeem soj ntsuam ntau yam piv txwv ntawm cov xwm txheej electrostatic, suav nrog cov kev nyiam yooj yim ntawm lub hnab yas thiab ib tus tes lossis lub tshuab luam ntawv thiab laser luam ntawv. Lub sij hawm electrostatics suav nrog kev tsim cov nqi ntawm cov khoom vim kev sib cuag ntawm qhov chaw. Feem ntau, tus nqi pauv tshwm sim thaum twg ob qhov chaw sib cuag thiab sib cais, tab sis qhov cuam tshuam ntawm cov nqi sib pauv feem ntau tau pom thaum tsawg kawg yog ib qho ntawm qhov chaw muaj kev tiv thaiv hluav taws xob txaus. Qhov no tshwm sim vim hais tias cov nqi hloov pauv ntawm qhov chaw raug kaw nyob rau lub sijhawm ntev, uas yog txaus rau kev soj ntsuam. Tom qab ntawd, cov nqi hluav taws xob no zoo li nyob rau ntawm qhov khoom ntawm qhov chaw kom txog thaum cov nqi xa tawm mus rau hauv av los yog sai sai neutralized los ntawm kev tso tawm.
Dab tsi yog Gravitational Force?
Gravitational force tuaj yeem piav qhia tias yog lub zog uas ua rau ntawm qhov khoom vim lub ntiajteb txawj nqus. Lub ntiajteb txawj nqus los yog gravitation yog ib tug txheej txheem ntuj pom nyob rau hauv txhua yam nrog ib tug loj los yog lub zog, piv txwv li, ntiaj chaw, hnub qub, galaxies, thiab lub teeb. Lub zog gravitational yog lub zog tsis muaj zog tshaj plaws ntawm plaub qhov kev sib cuam tshuam ntawm lub cev (qhov peb lub zog yog kev sib cuam tshuam zoo, lub zog hluav taws xob, thiab kev sib cuam tshuam tsis muaj zog). Yog li ntawd, lub zog gravitational tsis muaj kev cuam tshuam loj heev ntawm qib ntawm subatomic hais. Txawm li cas los xij, nws yog qhov tseem ceeb ntawm kev sib cuam tshuam ntawm qib macroscopic, uas ua rau tsim, zoo li, thiab trajectory ntawm astronomical lub cev.
Daim duab 02: Lub Zog Loj
Peb tuaj yeem txhais lub zog gravitational raws li lub zog uas nyiam ob yam khoom uas muaj qhov tshwj xeeb. Peb hu nws lub zog txaus nyiam vim nws ib txwm ua rau ob pawg neeg rub ua ke thiab tsis txhob thawb lawv sib nrug. Newton txoj cai thoob ntiaj teb ntawm gravitation qhia tias txhua yam khoom nrog ib pawg yog rub rau txhua yam khoom hauv tag nrho lub qab ntuj khwb. Txawm li cas los xij, qhov kev quab yuam no feem ntau nyob ntawm qhov loj ntawm cov khoom; Piv txwv li, cov pawg loj loj qhia cov kev lom zem loj heev.
Qhov txawv ntawm Electrostatic Force thiab Gravitational Force yog dab tsi?
Qhov sib txawv tseem ceeb ntawm electrostatic force thiab gravitational force yog electrostatic force yog qhov txaus nyiam lossis quab yuam ntawm ob yam khoom siv hluav taws xob, hos lub zog gravitational yog qhov attraction ntawm ob yam khoom uas tshwm sim vim qhov cuam tshuam ntawm lub ntiajteb txawj nqus.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm electrostatic force thiab gravitational force nyob rau hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Electrostatic Force vs Gravitational Force
Qhov sib txawv tseem ceeb ntawm electrostatic force thiab gravitational force yog electrostatic force yog qhov txaus nyiam lossis quab yuam ntawm ob yam khoom siv hluav taws xob, hos lub zog gravitational yog qhov attraction ntawm ob yam khoom uas tshwm sim vim qhov cuam tshuam ntawm lub ntiajteb txawj nqus.
