Dab tsi yog qhov txawv ntawm Free Fall thiab Projectile Motion ? Dawb lub caij nplooj zeeg tuaj yeem tshwm sim hauv qab lub ntiajteb txawj nqus, tab sis projectile zog tuaj yeem tshwm sim hauv txhua qhov chaw quab yuam. Dawb lub caij nplooj zeeg yog ib rooj plaub tshwj xeeb ntawm projectile zog qhov twg qhov pib tshaj tawm yog xoom.

Nyob rau hauv no, dab tsi yog lub caij nplooj zeeg dawb thiab projectile motion?

Cov khoom yuav txav mus rau pem hauv ntej, thiab nce los yog nqes-tej zaum nce mus thiab tom qab ntawd nqes mus-thaum txuas ntxiv mus rau pem hauv ntej. Nyob rau hauv txhua rooj plaub ntawm kev poob siab , cov tsab ntawv tsa suab ntawm cov khoom (feem ntau hu ua projectile thaum kev poob siab yog nyob rau hauv kev txiav txim siab) txhua qhov chaw nyob hauv ib lub dav hlau ntsug.

Tsis tas li ntawd, tus qauv ntawm qhov projectile zog yog dab tsi? 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.

Ib sab ntawm qhov no, txhais li cas los ntawm kev caij nplooj zeeg dawb?

Hauv Newtonian physics, dawb poob yog ib qho tsab ntawv tsa suab ntawm lub cev uas lub ntiajteb txawj nqus tsuas yog lub zog ua rau nws. Nyob rau hauv cov ntsiab lus ntawm kev sib piv dav dav, qhov twg gravitation raug txo mus rau qhov chaw-lub sij hawm curvature, lub cev nyob rau hauv dawb poob tsis muaj zog ua rau nws.

Puas yog qhov projectile txav tsis poob?

1 Teb. Lub ntsiab txhais ntawm dawb poob yog hais tias ib yam khoom yog undergoing downward acceleration nyob rau hauv tus ntawm tsuas yog gravitational quab yuam. Vim li no, projectile zog tuaj yeem suav tias yog dawb poob raws li nws yog poob vim lub ntiajteb txawj nqus ib leeg.
