Kab rov tav ceev ntawm ib qhov projectile yog tas li (ib qho tsis hloov pauv hauv tus nqi), Muaj qhov ntsug kev ceev tshwm sim los ntawm lub ntiajteb txawj nqus; nws tus nqi yog 9.8 m / s / s, down, ntsug ceev Kev hloov pauv ntawm qhov projectile los ntawm 9.8 m / s txhua thib ob, kab rov tav ntawm qhov projectile yog ywj siab ntawm nws txoj kev txav ntsug.

Nyob rau hauv txoj kev no, hom kev txav twg yog qhov ntsug ntawm qhov projectile?

Raws li tau tham ua ntej hauv zaj lus qhia no, a projectile yog ib yam khoom uas tsuas yog lub zog ua haujlwm yog lub ntiajteb txawj nqus. Ntau projectiles tsis tsuas yog undergo ib ntsug motion , tab sis kuj undergo ib kab rov tav tsab ntawv tsa suab . Ntawd yog, thaum lawv txav mus rau sab saud lossis nqes lawv kuj tseem txav mus rau kab rov tav.

Tsis tas li ntawd, dab tsi yog 2 hom kev tawm suab? 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 qeb (rau tsab ntawv tsa suab 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 tsab ntawv tsa suab tseem zoo li qub los tsis.

Tsis tas li ntawd, dab tsi yog ntsug motion?

Vertical Motion . Vertical zog yog hu ua kev txav mus los ntawm cov khoom tiv thaiv lub gravitational rub. Nws yog tus tsab ntawv tsa suab uas yog perpendicular rau qhov ncaj los yog tiaj tus. Qhov ceev ntawm lub kheej kheej nyob rau hauv upward tsab ntawv tsa suab yog sib npaug rau qhov nrawm ntawm nqes tsab ntawv tsa suab.

Dab tsi yog tus qauv rau kev txav ntawm qhov projectile?

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 ntau ntawm cov khoom, muab lub kaum sab xis pib thiab pib tshaj tawm pom nrog: R = v2isin2θig R = v i 2 sin ? 2 ib g.
