Rau kos ib dawb - daim duab lub cev , peb kos qhov khoom ntawm kev txaus siab, kos txhua lub zog ua haujlwm ntawm qhov khoom ntawd, thiab daws txhua yam zog vectors rau hauv x- thiab y-components. Peb yuav tsum kos ib cais dawb - daim duab lub cev rau txhua yam khoom hauv qhov teeb meem.

Hais txog qhov no, daim duab dawb lub cev nrog piv txwv yog dab tsi?

Piv txwv : Ib qho thaiv ntawm lub dav hlau inclined A yooj yim dawb lub cev daim duab , qhia saum toj no, ntawm ib qho thaiv ntawm ib qho ramp qhia qhov no. Tag nrho cov kev txhawb nqa sab nraud thiab cov qauv tau hloov los ntawm lub zog uas lawv tsim. Cov no suav nrog: mg: qhov khoom ntawm qhov loj ntawm qhov thaiv thiab qhov tsis tu ncua ntawm gravitation acceleration: nws qhov hnyav.

Ib yam li ntawd, 5 hom quab yuam yog dab tsi? Action-at-a-Distance Forces

  • Ib txwm quab yuam.
  • Frictional Force.
  • Cua Resistance Force.
  • Lub zog quab yuam.
  • Caij nplooj ntoos hlav Force.

Tom qab ntawd, ib tug kuj yuav nug, Newton's 3 txoj cai yog dab tsi?

Newton 's peb kev cai ntawm cov lus tsa suab yuav raug teev raws li hauv qab no: Txhua yam khoom nyob rau hauv ib lub xeev ntawm ib qho kev taw qhia yuav nyob twj ywm nyob rau hauv lub xeev ntawm tsab ntawv tsa suab tshwj tsis yog ib tug sab nraud quab yuam ua rau nws. Force sib npaug lub sij hawm loj acceleration . Rau txhua qhov kev txiav txim muaj qhov sib npaug thiab tawm tsam.
