Ib yam khoom launched rau hauv projectile zog yuav muaj lub kaum sab xis pib pib qhov twg los ntawm 0 txog 90 degrees. Qhov siab tshaj plaws ntawm ib yam khoom, muab lub kaum sab xis pib thiab pib tshaj tawm pom nrog: h = v2isin2θi2g h = v i 2 sin 2 ? ib 2 g.

Nyob rau hauv no txoj kev, koj yuav ua li cas xam projectile motion?

Projectile motion equations

  1. Kab rov tav velocity tivthaiv: Vx = V * cos(α)
  2. Vertical velocity component: Vy = V * sin(α)
  3. Lub sijhawm ya davhlau: t = 2 * Vy / g.
  4. Ntau yam ntawm qhov projectile: R = 2 * Vx * Vy / g.
  5. Qhov siab tshaj plaws: hmax = Vy² / (2 * g)

Tsis tas li ntawd, vim li cas qhov projectile motion tseem ceeb? Cov projectile zog hais txog ib qho tseem ceeb nam ntawm qhov acceleration tsis tu ncua uas txawm tias tsis tu ncua acceleration, uas yog qhov tseem ceeb unidirectional, muaj peev xwm tsim tau ob seem kev taw qhia . Qhov laj thawj yog vim li cas lub zog thiab qhov pib tshaj tawm ntawm cov khoom tsis nyob rau tib qho kev taw qhia.

Piv txwv li, qhov projectile motion yog dab tsi?

A projectile yog ib yam khoom uas tsuas yog lub zog yog lub ntiajteb txawj nqus. Lub ntiajteb txawj nqus ua rau cuam tshuam rau ntsug kev taw qhia ntawm projectile , yog li ua rau ib tug ntsug acceleration. Kab rov tav kev taw qhia ntawm projectile yog qhov tshwm sim ntawm qhov nyiam ntawm txhua yam khoom hauv kev taw qhia kom nyob twj ywm hauv kev taw qhia ntawm qhov nrawm nrawm.

Muaj pes tsawg hom projectile motion muaj?

Projectile zog tuaj yeem tshwm sim hauv txoj kev ncaj, ncig, parabolic, hyperbolic, elliptical thiab lwm yam. Projectile zog tuaj yeem muab faib ua ob pawg (rau kev taw qhia nyob rau hauv ib lub dav hlau nyob rau hauv parabolic txoj kev) nyob ntawm seb lub kab rov tav theem ntawm lub projectile thaum lub sij hawm kev taw qhia tseem zoo li qub los tsis.
