Kodi mudakwerapo njinga yamoto kapena galimoto? Tikukhulupirira kuti ayi 🙂 hehe… kukhala m'nkhalango 😀 Ngati njinga yamoto kapena galimoto yomwe ikuyendetsedwa ikuyenda molunjika ndipo liwiro lake ndi losasintha, mwachitsanzo 60 km/h ndiye kuti njinga yamoto kapena galimotoyo ikuyenda molunjika pa liwiro losasintha (GLB). Sitima zoyenda pansi kapena ndege nthawi zina zimachitanso GLB. N'zosavuta kuona zinthu zikuyenda molunjika m'moyo watsiku ndi tsiku koma n'zovuta kuona zinthu zikuyenda GLB. Kodi mungatchule chitsanzo cha GLB chomwe mudachiwona kapena kuganizira?
Kumvetsetsa GLB
Chinthu chimagwira ntchito ngati liwiro la chinthucho ndi losasintha. Kecepatan merupakan kuchuluka kwa vekitalaChifukwa chake liwiro limapangidwa ndi liwilo lalikulu dani njira ya liwiro. Kuwongolera liwiro = njira yosunthira = njira yoyendera chinthu. Kuwongolera liwiro lokhazikika = njira yoyendera chinthu ndi yokhazikika = chinthu chimayenda molunjika. Liwiro lokhazikika kapena liwiro = liwiro kapena liwiro nthawi zonse limakhala lofanana nthawi zonse. Ngati liwiro la chinthu = 10 m/s ndiye kuti bola chinthucho chikuyenda, liwiro lake nthawi zonse ndi 10 m/s.
Mwachitsanzo, ngati chinthu chikuyenda pa liwiro losasintha la 10 m/s, ndiye kuti chimayenda mamita 10 sekondi iliyonse. Sekondi imodzi pambuyo pake, chinthucho chasuntha mamita 10 kuchokera pamalo ake oyambira. Masekondi awiri pambuyo pake, chinthucho chasuntha mamita 20 kuchokera pamalo ake oyambira. Masekondi atatu pambuyo pake, chinthucho chasuntha mamita 30 kuchokera pamalo ake oyambira. Ndi zina zotero… Ngati chinthu chikuyenda pa liwiro losasintha la 60 km/h, ndiye kuti chimayenda makilomita 60 ola lililonse. Ola limodzi pambuyo pake, chinthucho chasuntha makilomita 60 kuchokera pamalo ake oyambira. Maola awiri pambuyo pake, chinthucho chasuntha makilomita 120 kuchokera pamalo ake oyambira. Ndi zina zotero…
GLB ndi kayendedwe ka liwiro losasintha (kukula ndi komwe liwiro likupita sizisintha), motero palibe kuthamanga komwe kumachitika poyenda molunjika mofanana. Tiyenera kudziwa kuti GLB yomwe imachitika pamwamba pa Dziko Lapansi kapena pamwamba pa mapulaneti ena imachitika molunjika kokha, osati molunjika chifukwa mphamvu yokoka imagwira ntchito molunjika ndipo imathamanga. kugwa kwaulere mbali yolunjika.
RFomula Yoyendera Yofanana Yoyenda Molunjika
Fomula yoyendera mzere wofanana imafotokoza ubale womwe ulipo pakati pa kuchuluka kwa thupi mu kuyenda kofanana kwa mzere. Pali kuchuluka kwa thupi mu kuyenda kofanana kwa mzere, kuphatikizapo: nthawi (chizindikiro ndi t, gawo lapadziko lonse lapansi ndi lachiwiri), mtunda kapena kusamuka (chizindikiro ndi s, gawo lapadziko lonse lapansi ndi mita) ndi liwiro kapena liwiro (chizindikiro ndi v, gawo lapadziko lonse lapansi ndi mita/sekondi)Ubale pakati pa kuchuluka kwa zinthu zitatu izi ukufotokozedwa kudzera mu fomula iyi:
v = s / t
Chithunzi Chofanana Choyenda Molunjika
Ubale pakati pa kuchuluka kwa zinthu zakuthupi pakuyenda molunjika umawonetsedwanso kudzera mu ma graph. Grafu ya liwiro-nthawi ndi graph ya mtunda-nthawi zikuwonetsedwa pachithunzi chili pansipa.
Chitsanzo cha mavuto
1. Galimoto yothamanga A ikuthamangitsa galimoto yothamanga B pa liwiro losasintha la 60 m/s. Galimoto yothamanga A ili kumbuyo kwa galimoto yothamanga B pa mtunda wa mamita 600 pa msewu wowongoka. Panthawiyo, galimoto yothamanga B ikuyenda pa liwiro losasintha la 30 m/s. Nthawi yofunikira kuti mukwaniritse galimoto yothamanga B ndi…
Zokambirana
Ndizodziwika kuti:
Liwiro lokhazikika la galimoto A (v)A) = 60 m/s
Liwiro lokhazikika la galimoto B (v)B) = 30 m/s
Mtunda pakati pa magalimoto A ndi B (s)AB) = mamita 600
Anafunsa kuti: Nthawi yofunikira kuti galimoto A ipitirire galimoto B
Yankho:
Kusiyana kwa liwiro la magalimoto A ndi B = 60 m/s – 30 m/s = 30 m/s
Fomula yoyendera molunjika mofanana:
v = s / t
v = liwiro, s = mtunda, t = nthawi
t = s / v = 600 / 30 = masekondi 20
Nthawi yofunikira kuti galimoto A idutse galimoto B ndi masekondi 20.
