Ib siv zog yog a zog uas yog siv rau ib yam khoom los ntawm ib tug neeg los yog lwm yam khoom. Yog hais tias aperson thawb lub rooj hla chav tsev, ces muaj ib qho siv zog ua raws li qhov khoom. Cov siv zog yog cov zog tus neeg siv tau tawm ntawm lub rooj.

Hauv qhov no, cov piv txwv ntawm kev siv dag zog yog dab tsi?

Hom kev siv dag zog

  • Nias. Feem ntau hom kev quab yuam yog thawb los ntawm kev sib cuag ntawm lub cev.
  • Rub. Koj tuaj yeem siv lub zog los ntawm kev rub ncaj qha rau ntawm ib qho khoom, xws li rub ntawm txoj hlua kom txav lub thawv.
  • Luag.
  • Cov khoom nyob ruaj ruaj.
  • Tsiv khoom.
  • Ntawm lub kaum sab xis.
  • Cov vev xaib.
  • Phau ntawv.

Qhov thib ob, plaub hom kev quab yuam yog dab tsi? Cov Plaub Qhov Tseem Ceeb ntawm Nature yog Gravitational zog , Tsis muaj Nuclear zog , Hluav taws xob zog thiab muaj zog Nuclear zog . Muaj zog thiab muaj zog zog tsuas yog siv tau dhau qhov luv luv thiab ua tus thawj ntawm qib ntawm subatomic particles. Gravity thiab Electromagnetic zog muaj infiniterange.

Kuj tseem paub, siv zog ua haujlwm li cas?

Ua haujlwm yog ua thaum a zog uas siv rau ib yam khoom txav qhov khoom ntawd. Cov ua haujlwm yog xam los ntawm kev muab cov zog los ntawm tus nqi ntawm kev txav ntawm ib qho khoom (W = F * d). A zog ntawm 10 newton, uas txav ib yam khoom 3 meters, ua 30n m ua ua haujlwm.

Hom kev quab yuam yog dab tsi?

Hauv paus, muaj ob hom rog , tiv tauj zog , thiab tsis sib cuag zog . Gravitational zog , hluav taws xob zog , sib nqus zog , nuclear zog , kev sib txhuam zog yog ib co piv txwv ntawm zog . Peb kawm paub meej txog yam zog ……
