Kos ntawm daim duab daim ntawv ob txoj kab ncaj nraim los ntawm tib lub ntsiab lus thiab perpendicular rau ib leeg. Qhov no yog x-y axis. X-axis yog kab rov tav thiab y-axis yog kab ntsug. Kos qhov tsim nyog sib npaug-spaced sij hawm ncua sijhawm ntawm x-axis kom koj tuaj yeem yooj yim daim duab tus sij hawm qhov tseem ceeb ntawm lub rooj.
Tom qab ntawd, qhov kev tshaj tawm qhia li cas ntawm txoj hauj lwm vs lub sij hawm daim duab?
Hauv ib txoj hauj lwm - lub sijhawm ua haujlwm , cov nrawm ntawm cov khoom txav yog sawv cev los ntawm txoj kab nqes, lossis steepness, ntawm daim duab kab. Yog tias daim duab kab yog kab rov tav, zoo li kab tom qab sij hawm = 5 vib nas this Daim duab 2 hauv daim duab hauv qab no, ces txoj kab nqes yog xoom thiab yog li ntawd nrawm . Cov txoj hauj lwm ntawm cov khoom tsis hloov.
Tsis tas li ntawd, tus qauv ntawm kev tshem tawm yog dab tsi? 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.
Nyob rau hauv no hais txog, dab tsi yog tus qauv rau nruab nrab tshaj tawm?
Nruab nrab ceev (v) ntawm ib yam khoom yog sib npaug rau nws qhov kawg nrawm (v) plus pib nrawm (u), muab faib ua ob. Qhov twg: ¯v = nruab nrab ceev . v = final nrawm.
Koj pom qhov nrawm li cas?
Faib tag nrho cov kev hloov pauv los ntawm lub sijhawm tag nrho. Nyob rau hauv thiaj li yuav nrhiav tus nrawm ntawm cov khoom txav, koj yuav tsum tau faib cov kev hloov pauv hauv txoj haujlwm los ntawm kev hloov hauv lub sijhawm. Qhia meej qhov kev taw qhia txav, thiab koj muaj qhov nruab nrab nrawm.

Yuav ua li cas nce lub sij hawm lub sij hawm?
Los ntawm sab saum toj mus rau hauv qab ib pawg, electronegativity txo. Qhov no yog vim tus naj npawb atomic nce ib pawg, thiab yog li muaj kev ncua deb ntawm valence electrons thiab nucleus, los yog ntau dua atomic radius
Yuav ua li cas koj kos ib qhov deb vs lub sij hawm daim duab?
Qhov nrug Lub Sijhawm graph yog kab graph uas qhia txog qhov kev ncua deb piv rau lub sijhawm pom ntawm daim duab. Kev kos duab nyob deb-lub sij hawm yog qhov yooj yim. Rau qhov no, peb xub muab ib daim ntawv ntawm daim duab kos thiab kos ob kab perpendicular rau nws conjoining ntawm O. Thehorizontal kab yog X-axis, thaum lub verticle kab yog Y-axis
Dab tsi yog qhov txawv ntawm lub xeev daim duab kos duab thiab daim duab ua haujlwm?
Lub xeev daim duab qauv yog siv los qhia qhov sib lawv liag ntawm lub xeev uas ib yam khoom mus dhau, qhov ua rau kev hloov ntawm ib lub xeev mus rau lwm qhov thiab qhov kev txiav txim uas tshwm sim los ntawm lub xeev hloov. Daim duab ua haujlwm yog ntws ntawm kev ua haujlwm yam tsis muaj qhov tshwm sim (kev tshwm sim) mechanism, lub xeev tshuab yog suav nrog lub xeev triggered
Yuav ua li cas koj pom lub sij hawm thiab amplitude ntawm ib daim duab?
Lub Sijhawm mus los ntawm ib lub ncov mus rau tom ntej (los yog los ntawm ib qho taw tes mus rau qhov sib piv tom ntej): Lub Amplitude yog qhov siab ntawm kab nruab nrab mus rau lub ncov (los yog mus rau lub trough). Tam sim no peb tuaj yeem pom: amplitude yog A = 3. lub sij hawm yog 2π / 100 = 0.02 π theem hloov yog C = 0.01 (mus rau sab laug) ntsug hloov yog D = 0
Yuav ua li cas koj xam lub sij hawm nws yuav siv sij hawm mus ncig teb chaws?
Kwv yees seb koj yuav mus sai npaum li cas ntawm koj qhov kev mus ncig. Tom qab ntawd, faib koj qhov kev ncua deb ntawm koj qhov nrawm. Qhov no yuav muab rau koj anestimation ntawm koj lub sijhawm mus ncig. Piv txwv li, yog tias koj mus ncig yog 240 mais thiab koj yuav tsav 40 mais ib teev, koj lub sijhawm yuav yog 240/40 = 6hours
