Hook's Law

Thaum cov khoom elastic, xws li lub caij nplooj ntoos hlav, yog ncab, qhov ntev ntev yog hu ua nws qhov txuas ntxiv. Qhov txuas ntxiv ntawm ib qho khoom elastic yog ncaj qha proportional rau lub zog siv rau nws: F yog lub zog hauv newtons (N) k yog 'caij nplooj ntoos hlav tas li' hauv newtons ib meter (N / m)

Hauv qhov no, Hooke Txoj Cai GCSE yog dab tsi?

Extension thiab compression Extension tshwm sim thaum ib yam khoom nce hauv qhov ntev, thiab compression tshwm sim thaum nws txo qhov ntev. Qhov txuas ntxiv ntawm cov khoom elastic, xws li lub caij nplooj ntoos hlav, tau piav qhia los ntawm Hook's law : force = spring constant × extension. Qhov no yog thaum: quab yuam (F) yog ntsuas hauv Newton (N)

Tsis tas li ntawd, Hooke txoj cai ntawm elasticity yog dab tsi? Hook's law , txoj cai ntawm elasticity nrhiav tau los ntawm tus kws tshawb fawb Askiv Robert Hooke nyob rau hauv 1660, uas hais tias, rau qhov me me deformations ntawm ib yam khoom, qhov hloov los yog loj ntawm lub deformation yog ncaj qha proportional rau lub deforming quab yuam los yog load.

Hauv qhov no, Hooke Txoj Cai siv rau dab tsi?

Hook's Law yog ib lub hauv paus ntsiab lus ntawm physics uas hais tias lub zog uas yuav tsum tau ncua los yog compress lub caij nplooj ntoos hlav los ntawm qee qhov kev ncua deb yog proportional rau qhov kev ncua deb. Ntxiv nrog rau kev tswj tus cwj pwm ntawm cov springs, Hook's Law kuj tseem siv tau rau ntau qhov xwm txheej uas lub cev elastic deformed.

Koj tshawb nrhiav Hooke txoj cai li cas?

Koj ua tau tshawb nrhiav Hooke's Law los ntawm kev ntsuas ntau npaum li cas paub quab yuam stretch lub caij nplooj ntoos hlav. Ib txoj hauv kev yooj yim los siv lub zog ua kom paub tseeb yog cia qhov hnyav ntawm qhov paub qhov hnyav yog lub zog siv los ncab lub caij nplooj ntoos hlav. Lub zog tuaj yeem suav los ntawm W = mg.
