Ib txhia piv txwv ntawm Projectile Motion yog Football, A baseball, Cricket ball, lossis lwm yam khoom. Qhov projectile motion muaj ob ntu - ib qho yog tus kab rov tav tsab ntawv tsa suab tsis muaj acceleration thiab tus lwm ntsug tsab ntawv tsa suab ntawm tas li acceleration vim lub ntiajteb txawj nqus.

Tsis tas li ntawd nug, dab tsi yog qhov projectile motion piv txwv?

Piv txwv li, koj pov pob ncaj nraim mus rau pem hauv ntej, lossis koj ncaws pob thiab muab nws nrawm ntawm lub kaum sab xis mus rau kab rov tav lossis koj tsuas yog tso cov khoom thiab ua rau lawv poob; tag nrho cov no yog cov piv txwv ntawm kev txav mus los. Nyob rau hauv qhov projectile motion, lub ntiajteb txawj nqus yog tib lub zog ua rau lub khoom.

Qhov thib ob, hom projectile yog dab tsi? Nyob rau hauv ib qhov Projectile Motion, muaj ob lub simultaneous ywj siab rectilinear tsab ntawv tsa suab:

  • Raws li x-axis: uniform ceev, lub luag hauj lwm rau kab rov tav (forward) motion ntawm cov particle.
  • Raws li y-axis: uniform acceleration, lub luag hauj lwm rau ntsug (downwards) motion ntawm particle.

Piv txwv li, qhov projectile motion yog dab tsi?

Projectile zog yog ib daim ntawv ntawm tsab ntawv tsa suab ntsib los ntawm ib yam khoom los yog particle (a projectile ) uas tau kwv yees nyob ze ntawm lub ntiaj teb saum npoo thiab txav mus raws txoj kev nkhaus nyob rau hauv qhov kev txiav txim ntawm lub ntiajteb txawj nqus nkaus xwb (tshwj xeeb, qhov cuam tshuam ntawm huab cua tiv thaiv tau suav tias yog qhov tsis txaus ntseeg).

Qhov projectile thiab projectile motion yog dab tsi?

Projectile zog yog cov tsab ntawv tsa suab ntawm ib yam khoom pov los yog projected rau saum huab cua, tsuas yog acceleration ntawm lub ntiajteb txawj nqus. Cov khoom hu ua a projectile , thiab nws txoj kev yog hu ua nws trajectory.
