Projectile motion is a form of motion where an object moves in a parabolic path parabolic path In astrodynamics or celestial mechanics a parabolic trajectory yog Kepler orbit with the eccentricity equal to 1 thiab yog lub voj voog tsis sib haum uas yog nyob ntawm ciam teb ntawm elliptical thiab hyperbolic. Thaum tsiv tawm ntawm qhov chaw nws yog hu ua kev khiav tawm orbit, txwv tsis pub ntes lub orbit. https://en.wikipedia.org › wiki › Parabolic_trajectory
Parabolic trajectory - Wikipedia
. Txoj kev ua raws li cov khoom yog hu ua nws txoj kev taug. Qhov kev txav txav ntawm qhov projectile tshwm sim thaum lub zog siv rau thaum pib ntawm txoj hauv kev rau kev tso tawm (tom qab qhov projectile tsuas yog raug rau lub ntiajteb txawj nqus).
Puas yog projectile ib txoj kev?
Projectile motion yog qhov kev txav ntawm ib qho khoom pov tseg lossis npaj rau saum huab cua, tsuas yog ua kom nrawm nrawm ntawm lub ntiajteb txawj nqus. Cov khoom yog hu ua projectile, thiab nws path yog hu ua nws txoj kev.
Txoj kev taug kev yog dab tsi?
Nws yog ib daim ntawv ntawm kev txav uas ib yam khoom uas muab pov rau hauv huab cua taug kev nkhaus hauv qab qhov kev ua ntawm lub ntiajteb txawj nqus. Tsis tas li ntawd, qhov projectile yog ib yam khoom uas tau muab pov rau saum huab cua thiab txoj hauv kev yog txoj hauv kev uas nws ua raws.
Dab tsi yog qhov sib npaug ntawm trajectory hauv qhov projectile?
Teb: Li no qhov sib npaug ntawm qhov sib npaug ntawm qhov projectile yog y=x√3 - 0.544x2.
Yuav ua li cas yog hom phiaj xwm phiaj xwm?
Ntau qhov projectiles tsis yog tsuas yog ua haujlwm ntsug xwb, tab sis tseem dhau mus rau kab rov tav. Ntawd yog, thaum lawv txav mus rau sab saud lossis nqes lawv kuj tseem txav mus rau kab rov tav. Muaj ob lub ntsiab lus ntawm qhov projectile cov lus tsa suab - kab rov tav thiab ntsug.
