FNet = F1 + F2 + F3….

Thaum lub cev so, lub net zog qauv yog muab los ntawm, F Net = Fa + Fg.

Tsis tas li ntawd, net force xam li cas?

Cov net zog tsuas yog tus lej ntawm tag nrho cov no zog ua rau ib yam khoom. Qhov kev sib npaug no yog qhov sib npaug ntawm n zog ua yeeb yam ntawm ib yam khoom. Qhov loj ntawm lub net zog ua yeeb yam ntawm ib yam khoom yog sib npaug rau qhov loj ntawm cov khoom sib npaug los ntawm kev nrawm ntawm cov khoom, raws li qhia hauv cov qauv no.

Ib tug kuj yuav nug, kuv yuav xam cov quab yuam li cas? Txoj Kev 2 Ib txwm quab yuam ntawm ib qho Incline

  1. Siv qhov sib npaug zoo. Txhawm rau xam qhov qub quab yuam ntawm ib qho khoom ntawm lub kaum sab xis, koj yuav tsum siv tus qauv: N = m * g * cos(x)
  2. Nrhiav lub cosine ntawm lub kaum sab xis.
  3. Nrhiav qhov khoom hnyav.
  4. Muab ob qhov txiaj ntsig ua ke.
  5. Sau koj cov lus teb.

Ib yam li ntawd, koj tuaj yeem nug, Net Force piv txwv yog dab tsi?

A net zog yog qhov suav tag nrho zog ua yeeb yam ntawm ib yam khoom. A net zog Nws muaj peev xwm ua kom ceev ib pawg. Piv txwv li, yog tias lub log ntawm lub tsheb thawb nws mus rau pem hauv ntej nrog 5 Newtons thiab luag yog 3 Newton, net zog yog 2 Newton, pem hauv ntej. Kev txav mus rau sab xis yog qhov zoo. Kev txav mus rau sab laug yog qhov tsis zoo.

Ib qho piv txwv ntawm lub zog net yog dab tsi?

Rau piv txwv hauv lub caij nplooj zeeg dawb, lub net zog ntawm ib yam khoom sib npaug nws qhov hnyav - ib qho zog rub rau nws. Yog 2 zog thawb lossis rub rau ntawm ib qho khoom nyob rau sab nraud, thiab ob zog rho tawm ib leeg raws nraim, lub net zog yog zero. Hauv daim duab sab laug, lub net zog yog 2 Newton rau sab xis.
