Projectile motion equations
- Kab rov tav velocity tivthaiv: Vx=Vcos(α)
- Vertical velocity component: Vy=Vsin(α)
- sij hawm ya davhlau: t=2Vy / g.
- Range of the projectile: R=2VxVy/g.
- siab siab tshaj: hmax=Vy² / (2g)
Dab tsi yog qhov hloov pauv hloov pauv?
Hauv physics, koj pom qhov kev hloov pauv los ntawm kev suav qhov kev ncua deb ntawm qhov khoom pib thiab nws txoj haujlwm kawg. Hauv cov ntsiab lus physics, koj feem ntau pom kev hloov pauv hu ua qhov sib txawv s. Cov mis hloov chaw raug raws li nram no: s=sf – si . s=kev hloov pauv.
Yuav ua li cas thiaj nrhiav tau kev nrawm?
Acceleration (a) yog qhov hloov pauv hauv qhov nrawm (Δv) dhau qhov kev hloov pauv hauv lub sijhawm (Δt), sawv cev los ntawm kab zauv a=Δv/Δt. Qhov no tso cai rau koj los ntsuas qhov nrawm nrawm npaum li cas hloov pauv hauv meters ib ob squared (m / s^2). Acceleration kuj yog vector kom muaj nuj nqis, yog li nws suav nrog ob qho tib si loj thiab kev taw qhia.
Vfy txhais li cas hauv physics?
Variable Txhais: Δy yog ntsug txav hauv meters, Δx yog kab rov tav hloov pauv hauv meters, Vfy yog ntsug kawg tshaj tawm hauv meters / thib ob, Voy yog ntsug pib tshaj tawm hauv meters / Thib ob, Vx yog kab rov tav tshaj tawm hauv m / s, t yog lub sijhawm hauv vib nas this, thiab g yog acceleration vim lub ntiajteb txawj nqus hauv m / s / s.
Vxo suav li cas?
vxo yog tus nqi pib ntawm x-cov ntsiab lus ntawm kev tshaj tawm,i.e. vxo=vx[0]. vyo yog tus nqi pib ntawm y-component ntawm kev tshaj tawm, i.e. vyo=vy[0].
