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.

Dab tsi yog qhov sib piv thiab piv txwv?
Inverse proportion. Inverse proportions tshwm sim thaum ib tus nqi nce thiab qhov txo qis. Piv txwv li, ntau tus neeg ua haujlwm ntawm txoj haujlwm yuav txo lub sijhawm los ua kom tiav cov haujlwm. Lawv yog inversely proportional
Newton's 3 Laws of Motion thiab piv txwv yog dab tsi?
Piv txwv ntawm Newton's 3rd Law? Thaum koj dhia ntawm ib lub nkoj me me mus rau hauv dej, koj yuav thawb koj tus kheej mus rau hauv dej. Tib lub zog uas koj siv los thawb rau pem hauv ntej yuav ua rau lub nkoj txav rov qab. ? Thaum huab cua rushes tawm ntawm lub zais pa, qhov kev tawm tsam tawm tsam yog tias lub zais pa ya tuaj
Dab tsi yog qhov txawv ntawm freefall thiab projectile motion?
Qhov txawv ntawm Free Fall thiab Projectile Motion yog dab tsi? Lub caij nplooj zeeg dawb tuaj yeem tshwm sim nyob rau hauv lub ntiajteb txawj nqus, tab sis qhov projectile zog tuaj yeem tshwm sim hauv txhua qhov chaw quab yuam. Lub caij nplooj zeeg dawb yog qhov tshwj xeeb ntawm qhov kev txav ntawm qhov projectile qhov chaw pib tshaj tawm yog xoom
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
