1-Dimensional daws teeb meem cov kauj ruam
- 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)
- Sau qhov ntau npaum li cas koj tab tom nrhiav.
- Nrhiav tus kinematic sib npaug (los yog qee zaum ob kev sib npaug ) txhawm rau txheeb xyuas cov khoom no.
- daws lub algebra.
Tsis tas li ntawd, koj yuav daws qhov teeb meem physics li cas?
Cov kauj ruam
- Ua siab ntev.
- Nyeem dhau qhov teeb meem ib zaug.
- Kos ib daim duab.
- Sau txhua yam uas tau muab rau koj rau sab hauv qab ib pawg sau tias "paub".
- Saib rau qhov tsis paub hloov pauv.
- Sau cov qauv uas koj xav tias yuav siv tau rau qhov teeb meem no.
- Xaiv tus qauv tsim nyog.
- 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)

Koj daws teeb meem Hardy Weinberg li cas?
VIDEO Ib sab ntawm qhov no, koj pom P thiab Q li cas hauv Hardy Weinberg? Txij li thaum p = 1 - q thiab q paub, nws yog ua tau xam p ib yam nkaus. Paub p thiab q , nws yog ib qho yooj yim teeb meem rau ntsaws cov nqi no rau hauv Hardy - Weinberg equation (p² + 2pq + q² = 1).
Koj yuav daws qhov teeb meem li cas?
Ua ntej, sau qhov kev faib ua feem, siv ib tsab ntawv los sawv cev rau lub sij hawm uas ploj lawm. Peb pom cov khoom ntoo khaub lig los ntawm kev muab 20 npaug x, thiab 50 npaug ntawm 30. Ces faib mus nrhiav x. Kawm cov kauj ruam no kom ze, vim tias qhov no yog cov txheej txheem peb yuav siv ntau zaus hauv algebra
Yuav ua li cas koj nrhiav tau qhov kev daws teeb meem rau ib khub xaj?
Txhawm rau txheeb xyuas yog tias tus khub txiav txim yog qhov kev daws teeb meem rau qhov sib npaug, koj tuaj yeem ua qhov kev sim. Txheeb xyuas qhov x-tus nqi hauv tus khub xaj thiab ntsaws rau hauv qhov sib npaug. Thaum koj ua kom yooj yim, yog tias tus y-tus nqi koj tau txais yog tib yam li y-tus nqi hauv tus khub xaj, ces tus khub txiav txim yog qhov kev daws teeb meem rau qhov sib npaug
Yuav ua li cas koj thiaj paub yog tias tus nqi sib npaug tsis muaj kev daws teeb meem?
Tus nqi tiag tiag ntawm tus lej yog nws qhov kev ncua deb ntawm xoom. Tus lej ntawd yuav yog qhov zoo, vim koj tsis tuaj yeem ua tsis zoo ob txhais taw deb ntawm ib yam dab tsi. Yog li txhua tus nqi sib npaug sib npaug sib npaug rau tus lej tsis zoo yog tsis muaj kev daws teeb meem, txawm tias tus lej ntawd yog dab tsi
Koj yuav daws qhov teeb meem txoj kab nqes li cas?
Txheeb xyuas txoj kab nqes, m. Qhov no tuaj yeem ua tiav los ntawm kev suav cov nqes hav ntawm ob lub ntsiab lus ntawm txoj kab uas siv cov qauv nqes hav. Nrhiav y-intercept. Qhov no tuaj yeem ua tau los ntawm kev hloov txoj kab nqes thiab cov kev sib koom ua ke ntawm qhov taw tes (x, y) ntawm txoj kab hauv txoj kab nqes-intercept formula thiab tom qab ntawd daws rau b
