The yokuita "Speed, nguva, kure." Kugadzirisa dambudziko?

Regai chikoro Physics chidzidzo ikava inonakidza mutambo! Munyaya ino, heroine redu richava yokuita "Speed, nguva, kure." Ongorora oga mumwe parameter, ratinoparidza mienzaniso dzinonakidza.

havukavu

Chii chiri "nokukurumidza"? Unogona kuona kuti imwe motokari Zvinokurumidza, mumwe munhu zvishoma nezvishoma; mumwe murume achitaura briskly, mumwe - kwete kukurumidza. Cyclists uyewo kufamba aimhanya siyana. Hongu! Kuti unodiwa. Chii chinorehwa nayo? Chokwadi, daro kuti aiva murume. Ini adzinga motokari vamwe chaiyo. Kufunga kuti munhu vakurumidze 5 km / h. Iwoyo 1-awa, akanga 5 makiromita.

How kuwana akurumidze, nguva, kure? Ngatitange nokukurumidza. Nyatsoongorora, chii kunoyerwa? Sezvingatarisirwa, km / h m / s. Kune dzimwe dzakabatana, semuenzaniso, km / s (mu nzvimbo), mm / h (mu nemakemikari omuviri). Nyatsoteerera chii anomira pamberi "/" chiratidzo uye pashure. Chokutanga, zvinoreva "rwakapetwa", izvo zvinoreva kuti numerator - neMM, km m, ari dhinomineta - H, Gospels, min. Chechipiri, zvinoita sekuti izvi zvakafananidzirwa yemaitiro, handizvo here? Makiromita, mamita - chinhambwe, urefu, uye awa, wechipiri, miniti - nguva. Zvikuru nokuti muromo. Zvaiva nyore kuyeuka sei kuwana akurumidze, tarirai hapana chikwata (km / h, m / s). Words ndoga:

v = S / t = km / h.

nguva

Chii nguva? Chokwadi, zvinoenderana pakukurumidza. Somuenzaniso, muchimirira pachikumbaridzo amai imba uye mukoma. Vanofamba kubva kuchitoro. Hama akauya ipapa. Amai aifanira kumirira anenge 5 maminitsi Sei? Nekuti vakanga pamwero yakasiyana. Chokwadi, nokukurumidza kusvika kwauri kuenda, unofanira kuwedzera kukwira mhanyisa kutama kuti vomanikidza "gasi" mumotokari kuoma, kuti kuparadzirwa nebhasikoro. Chete kana nenhokwe, ngwarira uye vakasvinurira kuitira kuti chitsama kupinda munhu kana kuti chimwe chinhu.

How kuwana nguva? Tine muromo nokukurumidza - km / h. Uye sei kuva pamwe nguva? Chokutanga, nguva iri akayera mumaminitsi, mumasekonzi, maawa. The yokuita "Kasira, nguva, kure" riri kushandurwa sezvinotevera:

nguva T [chik., min., hr] = S [m, neMM,? km] / V [m / s, mm / Maminitsi, km / h].

Kana iwe exchange chikamu zvose nemitemo wemasvomhu, kupfupisa chinhambwe parameter (kureba), inoramba chete rwechipiri, kweminiti kana awa.

Distance, nzira urefu zvaiyambuka

Pano zvichava nyore kufamba, kazhinji, vatyairi vane rwendo odometer mumotokari. Vachakwanisa kuona sei makiromita vaifamba zhinji, asi vanoziva nokukurumidza. Asi sezvo sangano gogonera, ipapo kuisa tonoe Kutama zvikasashanda, kana isu kutora avhareji nokukurumidza.

Formula nzira (kure) - zvinobikwa velocity uye nguva. Zvechokwadi, kupfuura yakakunakira oornag chisarudzo - yava nguva. Wachi iri zvachose. chime havukavu hachisi 5 km / h, uye anenge. Saka, pangava kukanganisa. Pakadaro, mungadai nani kutora mepu yacho. Cherechedza akamboona. Zvinofanira sezvinoratidzwa mangani makiromita kana metres 1 cm. Kochekera mutongi uye kuyera kureba. Somuenzaniso, kubva kumusha chikoro mumhanzi yakananga mugwagwa. Chidimbu A yachinja 5 masendimita nedanda rechikero akaratidza 1 masendimita = 200 M zvinoreva kuti daro chaiye - .. 200 * 5 = 1000 M = 1 km. How zvikuru muende daro? Kwehafu yeawa? Zvazviri kutaura, 30 = 0.5 Maminitsi H = (1/2) maawa. Kana isu kugadzirisa dambudziko, zvinoitika kuti vaende ari kumhanya 2 km / h. Nguva dzose kuchakubatsira kugadzirisa dambudziko racho payakavakirwa "nokukurumidza, nguva, kure."

Regai kurasikirwa!

Ndinokukurudzirai kuti murege kurasikirwa inokosha chaizvo pfungwa. Kana wapiwa basa, nyatsoteerera pane zviumbu dzinopiwa parameters. Problem Author anogona vabiridzire. Anonyora ari kupiwa:

Murume akadzinga muvhu pamusoro bhasikoro 2 makiromita mumaminitsi 15. Usamhanye pakarepo kugadzirisa dambudziko vachishandisa nzira, zvimwe iwe wawana chinhu, iwe mudzidzisi hazvingaiti kuverenga. Yeuka kuti chero zvazvingava hazvibviri kuita saizvozvo: 2 km / 15 min. Iwe kuwana chikwata yakayerwa km / m, kwete km / h. Unofanira kuzadzisa yokupedzisira. Isa miniti iri wachi. How kuzviita? maminitsi 15 -. Hazvina 1/4 awa kana maawa 0.25 anogona zvino rakachengetwa 2km / 0,25ch = 8 km / h. Zvino dambudziko rave kugadziriswa nemazvo.

Ndicho nyore kuyeuka payakavakirwa "Kasira, nguva, kure." Just kutevera zvose nemitemo wemasvomhu, kuteerera vezvikwata iri dambudziko. Kana pane nuances, wakafanana muenzaniso kumusoro chete pamusoro, pakarepo kushandura muna SI zviyero, sezvaitarisirwa.
