Thermodynamics: Kinetic thiab Muaj Peev Xwm Zog . Kinetic zog yog zog muaj los ntawm ib yam khoom nyob rau hauv motion. Lub ntiaj teb revolving ib ncig lub hnub, koj taug kev ntawm txoj kev , thiab molecules txav hauv qhov chaw txhua tus muaj kinetic zog.

Ib yam li ib tug yuav nug, yog Qab Zib muaj peev xwm lossis lub zog kinetic?

Cov chemical bonds hauv qab zib tawg li cov qab zib yog digested rau carbon dioxide thiab dej. Thaum cov chemical bonds tawg, lub muaj peev xwm zog yog tso tawm nyob rau hauv daim ntawv ntawm kinetic zog los yog zog ntawm kev txav thiab cua sov los yog tsis siv tau zog.

Tsis tas li ntawd, piv txwv ntawm lub zog muaj peev xwm yog dab tsi? Piv txwv ntawm lub zog muaj peev xwm suav nrog: Ib pob zeb zaum ntawm ntug pob tsuas. Yog pob zeb ntog, lub muaj peev xwm zog yuav hloov mus rau kinetic zog , raws li lub pob zeb yuav txav mus. Ib tug stretched elastic hlua nyob rau hauv ib tug longbow. Thaum cov hlua elastic raug tso tawm, nws yuav ua rau tus xub tua rau pem hauv ntej.

Tom qab ntawd, lo lus nug yog, yog tus neeg caij tsheb kauj vab pedaling nce toj roob kinetic zog?

Yog hais tias koj pedal ib lub tsheb kauj vab ntawm qhov ceev ntawm ib theem ntawm cov av, nws muaj ib tug ruaj khov npaum li cas. kinetic zog . Raws li nws ceev thiab txoj kab nqes yog tas li, nws / nws kinetic zog yog tas li. Cov mis yog KE = / m * v * v qhov m = mass thiab v = velocity.

Ib co piv txwv ntawm kinetic zog yog dab tsi?

13 Piv txwv ntawm Kinetic Zog hauv Lub Neej Txhua Hnub

  • Tsav Tsheb. Cov tsheb txav muaj qee qhov kinetic zog.
  • Bullet Los ntawm Phom. Ib lub mos txwv raug rho tawm ntawm rab phom muaj lub zog kinetic siab heev, thiab, yog li, nws tuaj yeem nkag tau yooj yim rau txhua yam khoom.
  • Flying Airplane.
  • Taug kev & Khiav.
  • Kev caij tsheb kauj vab.
  • Rollercoasters.
  • Cricket Pob.
