1-Dimensional daws teeb meem cov kauj ruam

  1. Sau txhua qhov kom muaj nuj nqis teeb meem muab rau koj (pib thiab zaum kawg txoj hauj lwm, thawj zaug thiab zaum kawg tshaj tawm, acceleration, sij hawm, thiab lwm yam)
  2. Sau qhov ntau npaum li cas koj tab tom nrhiav.
  3. Nrhiav tus kinematic sib npaug (los yog qee zaum ob kev sib npaug ) txhawm rau txheeb xyuas cov khoom no.
  4. daws lub algebra.

Tsis tas li ntawd, koj yuav daws qhov teeb meem physics li cas?

Cov kauj ruam

  1. Ua siab ntev.
  2. Nyeem dhau qhov teeb meem ib zaug.
  3. Kos ib daim duab.
  4. Sau txhua yam uas tau muab rau koj rau sab hauv qab ib pawg sau tias "paub".
  5. Saib rau qhov tsis paub hloov pauv.
  6. Sau cov qauv uas koj xav tias yuav siv tau rau qhov teeb meem no.
  7. Xaiv tus qauv tsim nyog.
  8. daws qhov sib npaug.

Kuj Paub, yog dab tsi yog tus qauv ntawm kev hloov chaw? Taw qhia rau lub Kev khiav tawm thiab Acceleration Equation Nws nyeem: Kev khiav tawm sib npaug qhov qub tshaj tawm los ntawm lub sij hawm ntxiv rau ib nrab ntawm qhov acceleration multiplied los ntawm lub square ntawm lub sij hawm. Ntawm no yog ib qho piv txwv teeb meem thiab nws txoj kev daws teeb meem uas qhia txog kev siv qhov sib npaug: Ib qho khoom txav nrog qhov nrawm ntawm 5.0 m / s.

Ntawm no, 3 kinematic equations yog dab tsi?

Peb lub hom phiaj nyob rau hauv seem no ces, yog kom muab tau tshiab kev sib npaug uas tuaj yeem siv los piav qhia txog kev txav ntawm ib qho khoom raws li nws peb kinematic variables: velocity (v), txoj hauj lwm (s), thiab lub sij hawm (t). Muaj peb txoj hauv kev los ua ke lawv: tshaj tawm-lub sijhawm, txoj haujlwm-lub sijhawm, thiab nrawm-txoj haujlwm.

Cov mis rau kinematics yog dab tsi?

Muaj plaub qhov sib npaug kinematic thaum qhov pib pib txoj hauj lwm yog lub hauv paus, thiab cov kev ceev yog tas li: v=v0+at. d=12(v0+v)t d=1 2(v0+v)t or alternally vaverage=dt. d=v0t+(at22)
