Cov Lub Sijhawm nrug deb yog kab daim duab uas denotes nrug piv rau lub sij hawm nrhiav tau ntawm daim duab . Teeb duab nrug deb - lub sijhawm ua haujlwm yooj yim. Rau qhov no, peb xub muab ib daim ntawv ntawm daim duab ntawv thiab kos ob kab perpendicular rau nws conjoining ntawm O. Thehorizontal kab yog X-axis, thaum lub verticle kab yog Y-axis.
Ib yam li ntawd, nws tau nug, qhov kev ncua deb ntawm ib txoj hauj lwm vs lub sij hawm yog dab tsi?
Raws li kuv paub, a txoj hauj lwm - sijhawm thiab hloov chaw- sij hawm yog tib yam nkaus - txawm tias koj tuaj yeem siv lub ntsiab lus txawv me ntsis. Ib qho kev hloov chaw lub sijhawm ua haujlwm tsuas qhia tau tias qhov khoom nyob qhov twg ntawm qhov muab sij hawm . A nyob deb - lub sijhawm ua haujlwm , nyob rau hauv qhov tseeb, tsis quav ntsej nyob rau hauv dab tsi lub tsheb ciav hlau istravelling.
Tsis tas li ntawd, tus qauv rau lub sij hawm yog dab tsi? Koj tuaj yeem siv qhov sib npaug qauv d = rt uas txhais tau hais tias nrug sib npaug lub sij hawm sij hawm . Yuav kom daws tau qhov ceev orrate siv lub qauv rau ceev, s = d / t uas txhais tau tias speedequals nrug muab faib los ntawm sij hawm . daws rau sij hawm siv cov formula rau lub sijhawm , t = d/s uas txhais tau tias sij hawm sib npaug nrug faib los ntawm kev ceev.
Ib yam li ib tug yuav nug, koj yuav piav qhia txog kev txav ntawm lub sijhawm nyob deb li cas?
Motion Graphs
- Motion Graphs.
- Piav qhov kev txav ntawm ib yam khoom yog qee zaus nyuaj rau ua nrog cov lus.
- Qhov ceev tsis tu ncua yog qhia ncaj nraim.
- Ib txoj kab steeper qhia tau hais tias qhov kev ncua deb dua nyob rau hauv ib lub sijhawm.
- Summary: Daim duab nrug deb qhia peb seb qhov khoom txav deb npaum li cas nrog lub sijhawm.
Lub sij hawm ncua deb qhia li cas?
Nyob zoo phooj ywg, In a ncua sij hawm graph , txoj kab nqes yog cov ntsuas qhov ceev uas ib yam khoom txav mus thiab nyob rau hauv qhov kev taw qhia. Nws depicts lub acceleration ntawm lub cev txav nrog hwm rau nyob deb nws npog hauv ib qho tshwj xeeb ntawm sij hawm.

Vim li cas qhov deb vs lub sij hawm daim duab nkhaus?
Lub hauv paus ntsiab lus yog qhov nqes hav ntawm kab ntawm aposition-time graph qhia cov ntaub ntawv muaj txiaj ntsig txog qhov nrawm ntawm qhov khoom. Yog tias qhov nrawm nrawm, ces qhov nqes hav yog qhov tsis tu ncua (piv txwv li, txoj kab ncaj nraim). Yog tias qhov nrawm hloov pauv, ces txoj kab nqes hloov (piv txwv li, ib qho nkhaus)
Yuav ua li cas koj kos ib lub nrawm vs lub sij hawm daim duab?
Kos rau ntawm daim ntawv kos duab ob 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 ntawm lub sijhawm sib npaug ntawm lub x-axis kom koj tuaj yeem yooj yim teeb tsa lub sijhawm muaj nuj nqis los ntawm lub rooj
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 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
Yuav ua li cas koj thiaj nrhiav tau qhov ceev vs lub sij hawm daim duab?
Txoj kab nqes ntawm txoj kab ntawm txoj hauj lwm vs lub sij hawm daim duab yog sib npaug rau qhov tshaj tawm ntawm cov khoom. Qhov nqes hav ntawm kab ntawm qhov tshaj tawm vs lub sij hawm daim duab yog sib npaug rau acceleration ntawm cov khoom
