Thaum lub net zog ntawm ib yam khoom yog sib npaug zos rau qhov no khoom yog los yog thaum so ( staticequilibrium ) lossis txav ntawm qhov nrawm nrawm ( dynamicequilibrium ).

Ib yam li ntawd, nws yog nug, thaum ib yam khoom nyob rau hauv equilibrium lub net force yog?

Hauv kev xaus, kev sib npaug yog lub xeev ntawm ib khoom uas tag nrho cov zog ua raws li nws yog balanced. Nyob rau hauv tas li ntawd, lub net zog 0 Newton.

Ib sab saum toj, dab tsi yog lub zog ntawm lub laub uas rub mus rau sab xis? Ib khub ntawm 5 - Newton zog nyob rau hauv tib txoj kev tsim ib net zog ntawm 10 newton. Yog hais tias tus 5 - newton zog nyob rau hauv opposite lus qhia, lub net zog iszero. Yog 10 newtons zog yog exerted rau lub txoj cai thiab 5 newtons rau sab laug, lub net zog yog 5 newton txoj cai.

Yog li ntawd, nws txhais li cas hais tias ib yam dab tsi nyob rau hauv mechanical equilibrium?

Mechanical equilibrium yooj yim txhais tau tias tias txhua lub zog ua haujlwm ntawm qhov chaw ntawm qhov system ua haujlwm tawm mus rau xoom. Qhov no suav nrog qhov sib txawv siab (uas, txwv tsis pub, yuav tsim ib lub zog net).

Copernicus hais li cas txog kev txav ntawm lub hnub?

Nicolaus Copernicus yog ib tug Polish astronomer uas tau tshaj tawm txoj kev xav tias tus Hnub Nws yog nyob ze ntawm qhov chaw nruab nrab ntawm lub ntiaj teb, thiab lub ntiaj teb, tig rau ntawm nws axis ib hnub twg, tig txhua xyoo nyob ib ncig ntawm lub ntiaj teb. Hnub . Qhov no hu ua theheliocentric, los yog Hnub -center, system.
