A zog yog rub, rub, lossis rub rau ntawm ib qho khoom uas cuam tshuam nws tsab ntawv tsa suab . Qhov kev txiav txim los ntawm a zog can ua rau ib qho khoom ua kom nrawm, nrawm, nres lossis hloov kev coj ua. Txij li thaum txhua qhov kev hloov pauv hauv qhov nrawm yog suav tias yog acceleration, nws ua tau yuav hais tias a zog ntawm ib yam khoom ua rau acceleration ntawm ib yam khoom.
Tib neeg kuj nug, ua li cas lub zog ua rau muaj zog?
quab yuam thiab Motion Forces ua rau tag nrho cov lus tsa suab. Txhua lub sijhawm tsab ntawv tsa suab ntawm ib yam khoom hloov, nws yog vim a zog tau siv rau nws. quab yuam ua tau ua rau ib yam khoom nyob ruaj ruaj los pib tsiv los yog a tsiv kwv yees hloov nws ceev los yog kev taw qhia los yog ob qho tib si. Ib qho kev hloov ntawm qhov ceev lossis kev taw qhia ntawm ib qho khoom hu ua acceleration.
Tsis tas li ntawd, yuav ua li cas lub zog tuaj yeem nres qhov khoom txav mus los? Yog ib khoom yog tsiv thiab muaj kev thov zog nyob rau hauv opposite kev taw qhia ntawm tsab ntawv tsa suab, lub khoom yuav decelerate los yog qeeb. Yog tias koj pov pob rau ntawm qhov nrawm, nws yuav qeeb qeeb thaum nws mus nce toj vim qhov zog ntawm lub ntiajteb txawj nqus. Ib decelerating zog can vim a txav khoom rau nres.
Tom qab ntawd, ib tug kuj yuav nug, ua li cas quab yuam cuam tshuam rau qib 3?
Thaum a zog ua raws li qhov khoom nws yuav ua rau muaj kev hloov ceev thiab/los yog kev taw qhia. Txhua zog uas yog siv rau ib yam khoom muaj zog thiab kev taw qhia. Rau txhua tus zog exerted rau ib yam khoom, muaj yog ib tug sib npaug thiab opposite zog ua yeeb yam rau nws. Qhov kev hloov ntawm kev ceev lossis kev taw qhia no ua rau tsab ntawv tsa suab.
Peb txoj cai ntawm kev hais lus hu ua dab tsi?
Cov peb txoj cai tau thov los ntawm Sir Isaac Newton txog kev sib raug zoo ntawm kev quab yuam, tsab ntawv tsa suab , acceleration, mass, thiab inertia. Qhov no txoj cai kuj yog hu ua tus txoj cai ntawm inertia. ♦ Newton thib ob txoj cai hais tias lub zog ua rau lub cev sib npaug rau qhov nrawm ntawm lub cev lub sijhawm nws qhov hnyav.

Dab tsi yog 2 hom kev quab yuam ntawm kev nyiam?
Cov rog no tuaj yeem muab faib ua 2 hom: Intramolecular rog: Intramolecular quab yuam ntawm attraction yog lub zog ntawm attraction uas khaws ib lub molecule ua ke. Intermolecular rog: Intermolecular rog yog lub zog ntawm kev nyiam lossis kev tawm tsam uas ua haujlwm ntawm cov khoom nyob sib ze (atoms, molecules lossis ions)
Dab tsi yog qhov txawv ntawm kev cuam tshuam kev cuam tshuam thiab kev cuam tshuam cuam tshuam?
Paub qhov txawv ntawm kev cuam tshuam kev tsim kho thiab kev cuam tshuam puas tsuaj. Kev tsim kev cuam tshuam tshwm sim thaum lub crests ntawm ob nthwv dej ntxiv ua ke. Kev cuam tshuam kev puas tsuaj tshwm sim thaum lub crest ntawm ib yoj raug txo los ntawm lub trough ntawm lwm tus
Vim li cas kev sib txhuam quab yuam tsis yog kev ruaj ntseg?
Lub zog yog hais tias tsis yog-conservative thaum ua hauj lwm tawm tsam nws tsis tseg los ntawm lub cev uas yog txav los ntawm lub zog. Ib qho piv txwv zoo ntawm hom kev quab yuam tsis yog kev sib txhuam. Thaum lub cev txav tawm tsam kev sib txhuam, kev ua haujlwm yuav tsum tau kov yeej kev sib txhuam. Kev ua haujlwm yog lub zog thiab yog li nws tsis tuaj yeem poob
Lub zog cua sov cuam tshuam li cas rau kev sib cuam tshuam tshuaj?
Cov tshuaj tiv thaiv tshuaj feem ntau cuam tshuam nrog kev hloov pauv ntawm lub zog vim kev tawg thiab tsim cov ntawv cog lus. Cov tshuaj tiv thaiv uas lub zog raug tso tawm yog cov tshuaj tiv thaiv exothermic, thaum cov uas siv lub zog cua sov yog endothermic
Dab tsi yog qee qhov piv txwv ntawm kev cuam tshuam tsis zoo ntawm tib neeg ib puag ncig kev cuam tshuam?
Kev ua liaj ua teb tuaj yeem cuam tshuam tsis zoo rau peb ib puag ncig, suav nrog kev poob ntawm biodiversity, dej paug, kev hloov pauv huab cua, av yaig thiab muaj kuab paug
