Cov txoj kab nqes ntawm ib lub nrawm daim duab sawv cev lub acceleration ntawm cov khoom. Yog li, tus nqi ntawm cov txoj kab nqes ntawm lub sijhawm tshwj xeeb sawv cev lub acceleration ntawm cov khoom nyob rau ntawd instant.
Kuj nug, txoj kab nqes ntawm qhov kev ncua deb piv rau lub sij hawm daim duab yog dab tsi?
Cov gradient ntawm qhov deb - lub sij hawm graph sawv cev qhov ceev ntawm ib yam khoom. Cov nrawm ntawm ib yam khoom yog nws ceev nyob rau hauv ib qho kev taw qhia. Cov txoj kab nqes ntawm a nrawm - lub sij hawm graph sawv cev acceleration ntawm ib yam khoom.
Kuj Paub, qhov ntau npaum li cas qhov nqes hav ntawm txhua daim duab sawv cev? On ib daim duab ntawm v piv rau lub sijhawm, dab tsi kom muaj nuj nqis ua txoj kab nqes ntawm duab sawv cev ? Cov txoj kab nqes yog sawv cev rau kev hloov pauv hauv v dhau qhov kev hloov pauv hauv lub sijhawm. Los ntawm kev txhais, qhov no yog acceleration.
Dhau li ntawm no, txoj kab nqes ntawm daim duab sawv cev li cas?
Cov txoj kab nqes ntawm ib txoj haujlwm linear sawv cev tus nqi hloov ntawm qhov kev ua haujlwm ntawd. Nyob ntawm seb koj kawm qhov twg txoj kab nqes kuj sawv cev qhov tsis tu ncua ntawm proportionality ntawm ob qhov ntau uas sib txawv ncaj qha nrog ib leeg (piv txwv li lawv qhov piv yog ib txwm muaj tus nqi tas li).
Tus qauv rau kev ceev yog dab tsi?
daws rau ceev los yog siv tus nqi formula rau ceev , s = d/t uas txhais tau tias ceev sib npaug nrug muab faib los ntawm lub sij hawm. Yuav kom daws tau lub sijhawm siv lub qauv rau lub sij hawm, t = d / s uas txhais tau hais tias lub sij hawm sib npaug zos nrug muab faib los ntawm ceev.

Cov kws kos duab hu li cas cov duab thiab cov duab siv los sawv cev rau cov yam ntxwv ntawm lub ntiaj teb nto?
Ntiaj Teb Kev Tshawb Fawb - Daim Ntawv Qhia Lub Ntiaj Teb Qhov Nto A B GLOBE Ib puag ncig uas sawv cev rau lub ntiaj teb nto. SCALE Siv los sib piv qhov deb ntawm daim ntawv qhia lossis lub ntiaj teb mus deb ntawm lub ntiaj teb nto. SYMBOLS Ntawm daim duab qhia chaw, cov duab siv los ntawm mapmakers sawv ntsug rau cov yam ntxwv ntawm lub ntiaj teb nto. TSEEM CEEB Ib daim ntawv teev cov cim siv rau ntawm daim ntawv qhia
Yuav ua li cas koj sau txoj kab nqes nqes intercept daim ntawv nyob rau hauv tus qauv daim ntawv?
Standard form yog lwm txoj hauv kev los sau daim ntawv nqes hav-intercept (as opposed to y=mx+b). Nws sau li Ax+By=C. Koj tuaj yeem hloov daim ntawv nqes hav-intercept rau cov qauv zoo li no: Y=-3/2x + 3. Tom ntej no, koj cais qhov y-intercept (qhov no nws yog 2) zoo li no: Ntxiv 3/2x rau txhua sab ntawm kab zauv kom tau qhov no: 3/2x + y = 3
Vim li cas txoj kab kab rov tav muaj txoj kab nqes ntawm 0?
Mathwords: Zero Slope. Txoj kab nqes ntawm kab rov tav. Kab rov tav kab muaj nqes 0 vim tias tag nrho nws cov ntsiab lus muaj tib y-coordinate. Yog li ntawd, tus qauv siv rau txoj kab nqes ntsuas rau 0
Qhov kab zauv twg sawv cev rau kab qhia ntawm daim duab Y 2x?
Slope-intercept form yog y = mx + b, qhov m yog txoj kab nqes thiab b yog y-intercept. Qhov no ua rau qhov sib npaug ntawm peb kab y = 2x + 0 lossis y = 2x
Dab tsi yog txoj kab nqes ntawm txoj hauj lwm vs lub sij hawm daim duab?
Lub hauv paus ntsiab lus yog tias txoj kab nqes ntawm txoj kab ntawm txoj hauj lwm-lub sij hawm daim duab yog sib npaug rau qhov nrawm ntawm cov khoom. Yog tias cov khoom txav nrog qhov nrawm ntawm +4 m / s, ces txoj kab nqes hav yuav yog +4 m / s. Yog tias cov khoom txav nrog qhov nrawm ntawm -8 m / s, ces txoj kab nqes hav yuav yog -8 m / s
