Momwe angagonjetsere ndi ntchito zoyenda? njira njira mavuto magalimoto

Masamu - ndithu nkhani yovuta, koma m'kupita sukulu izo kudutsa zonse. Makamaka vuto ophunzira vuto pa anayambitsa. Mmene angathetsere palibe mavuto ndi unyinji wa nthaŵi, kuyang'ana pa nkhaniyi.

Dziwani kuti ngati muchita, ndiye ntchitozi sadzachititsa mavuto alionse. Njira zothetsera akhoza zayambitsa automatism.

mitundu

Kodi zikutanthauzanji mtundu wa ntchito? Ndi wosavuta ndi wopepuka ntchito, yomwe ndi mitundu zotsatirazi:

• kumadza magalimoto;
• kufunafuna;
• Movement zosiyana;
• magalimoto pa mtsinje.

Tikupereka iliyonse njira kuganizira payokha. Ndithudi, ife disassemble zitsanzo chabe. Koma pamaso timapita pa funso mmene angathetsere vuto pa anayambitsa, m'pofunika kulowa chilinganizo chimene tiyenera polimbana ndi mwamtheradi zonse mwa ntchito za mtundu uwu.

Chilinganizo: S = V * T. A salira kumasulira: S - ndi njira, kalata V amatanthauza mathamangidwe, ndi kalata T ndi nthawi. mfundo zonse zimene tingasonyezere mawu a njira. Choncho, liwiro ndi njira kugawidwa ndi nthawi, ndi nthawi - ndiyo njira, anagawa ndi liwiro.

kuyenda kwa

Ndi mtundu ambiri ntchito. Kuti timvetse chisankho, ganizirani zotsatirazi. Zokwaniritsa: "njinga ena awiri anapita imodzi kwa mzake, njira kunyumba wina ndi mzake ndi 100 Km Kodi mtunda kudutsa mphindi 120, ngati amadziwika kuti mathamangidwe wa - 20 Km paola, ndipo chachiwiri - khumi.". Ife titembenukira kwa funso mmene angathetsere vuto mu njinga.

Kuti tichite zimenezi tiyenera kuyambitsa akuti wina, "kutseka liwiro". Chitsanzo wathu, kukhala wolingana ndi makilomita 35 pa ola limodzi (makilomita 20 pa ola + 15 Km paola). Chimenechi chidzakhala Chinthu choyamba kuthetsa vutolo. Kenako, chulukitsani awiri kutseka mathamangidwe monga iwo kusuntha maola awiri: 35 * 2 = 70 Km. Tinapeza mtunda njinga azifika pafupi maminiti 120. Patsalanso kanthu otsiriza: 100-70 = 30 makilomita. mawerengedwe Izi tinapeza mtunda pakati pa njinga. Yankho: 30 Km.

Ngati simukumvetsa mmene angathetsere vuto mu potsimikizira-kayendedwe, pogwiritsa ntchito njira liwiro, ntchito njira ina.

Njira yachiwiri

Choyamba, tiyenera kupeza njira imene anapambana wopalasa njinga loyamba: 20 * 2 = makilomita 40. Njira ya bwenzi 2: fifitini kuchulukitsa ndi awiri, wofanana makilomita atatu. Pindani mtunda kudutsa wopalasa njinga loyamba ndi lachiwiri: 40 + 30 = makilomita 70. Ife tikudziwa njira kuwalaka pamodzi, kotero yatsala njira zonse zinkayenda kuchotsera: 100-70 = 30 Km. Yankho: 30 Km.

Takambiranazi yoyamba ya mavuto apaulendo. Mmene angathetsere iwo, tsopano bwino, chitani pamaso lotsatira.

Countermovement

Ulili: "Kuyambira mink imodzi zosiyana anakwera hares awiri oyambirira liwiro - makilomita 40 pa ola limodzi, ndipo chachiwiri - 45 kph Kodi kutali ali Chrixitu maola awiri ..?"

Pano, monga chitsanzo yapita, pali njira ziwiri. Choyamba, ife zinthu m'njira bwino:

1. Njira ya kalulu loyamba: 40 * 2 = 80 Km.
2. Njira ya kalulu chachiwiri: 45 * 2 = 90 Km.
3. Njira imene iwo anapita pamodzi: 80 + 90 = 170 Km. Yankho: 170 Km.

Koma pali njira ina.

kuchotsa mlingo

Monga inu kale anaganiza, mu nthawi iyi, ofanana woyamba, padzakhala latsopano yaitali. Taonani mtundu zotsatirazi mavuto zoyenda, mmene angathetsere iwo ndi thandizo la ndalama kuchotsa.

Iye tili mu malo oyamba ndi ife tikupeza: 40 + 45 = 85 makilomita paola. Mpaka kudziwa zimene mtunda kuŵapatulanya, chifukwa deta onse kale: 85 * 2 = 170 Km. Yankho: 170 Km. Tafotokoza yothetsera mavuto pa zoyenda mu njira ya makolo, komanso ndi kutseka liwiro ndi kuchotsa.

kayendedwe pambuyo

Tiyeni tione chitsanzo cha vuto ndi kufuna kuthetsa izo palimodzi. Ulili: ". Sukulu awiri, Cyril ndi Anton, ndinasiya sukulu ndipo anasamukira pa liwiro la mamita 50 pa mphindi Kostya anawasiya mphindi zisanu pa liwiro la mamita 80 pa mphindi Patapita kuchuluka kwa nthawi lidzakudzidzimutseni Konstantin Cyril ndi Anton.?"

Choncho, mmene angathetsere mavuto pa anayambitsa pambuyo? Apa tiyenera liwiro njira. Only mu nkhani iyi sayenera anawonjezera, ndipo subtracted: 80-50 = 30 mamita pa mphindi. The kanthu yachiwiri kudziwa mmene mamita ambiri alekanitsa sukulu linanena bungwe fupa. Kuti zimenezi zitheke, 50 * 6 = 300 meters. The kanthu watha ife tikupeza nthawi imene Kostya andipeze Cyril ndi Anton. Kuti njira iyi mamita 300 ayenera kugawidwa ndi kutseka liwiro la mamita 30 pa mphindi: 300: 30 = mphindi 10. Yankho: patapita mphindi 10.

anapezazo

Kuchokera pa zokambirana pamwamba, n'zotheka kujambula zinthu zina:

• pamene kuthetsa magalimoto yabwino ntchito mlingo wa mgwirizano ndi kuchotsa;
• ngati ndi atali-zoyenda kapena kusuntha padera, makhalidwe awa ndi kuwonjezera velocities zinthu;
• Ngati ntchito kutsogolo kwa ife pa gulu kuthamangitsa, ndiye kudya chinthu mosiyana Komanso kuti ali wochotsera.

Taona zina mwa ntchito paulendo, mmene angachitire ndi, kuwamvetsa adapanga bwino mfundo zokhudza "kutseka liwiro" ndi "mlingo kuchotsa" patsala kuganizira mfundo yomaliza, ndicho mmene angathetsere mavuto pa kayendedwe ka mtsinje?

Inde

Mungapezeko kudzakomananso:

• ntchito ndi kayendedwe kwa mzake;
• kayendedwe kuthamangitsa;
• Movement zosiyana.

Koma mosiyana ndi ntchito yapita, mtsinje ali ndi nthenda mathamangidwe kuti sitingakane. Apa, zinthu kudzalimbikitsa kapena m'mphepete mwa mtsinjewo - ndiye mlingo ayenera anawonjezera kuti liwiro mwini wa zinthu, kapena otaya wa - m'pofunika kuchotsera kwa liwiro chinthu.

Chitsanzo cha vuto pa lamulo la mtsinje

Ulili: "kwakusiyana anapita ndi otaya pa liwiro la makilomita 120 pa ola limodzi ndipo anabwerera, ndipo nthawi maola osachepera awiri, kuposa ndi otaya ndi liwiro la madzi watercraft ataima Kodi.?" Tinapatsidwa mtengo otaya wofanana kilometre imodzi pa ola limodzi.

Ife chitani zochita. Tikupereka kulenga tchati mwachitsanzo zithunzi. Tiyeni ife titenge njinga yamoto liwiro mu madzi patsogolo pa ×, ndiye liwiro otaya ndi wofanana × + 1 ndi x-1 ndi. Distance ulendo wozungulira ndi 120 Km. Iwo likukhalira kuti nthawi anatengedwa kusuntha ndi otaya 120 (x-1), ndi otaya 120 (× + 1). Amadziwika 120 (x-1) kwa maola awiri ndi zosakwana 120 (× + 1). Tsopano ife angachititse kuti nadzaza tebulo.

Kodi tili: (120 / (1-x)) - 2 = 120 / (× + 1) kuchulukitsa mbali pa (× + 1) (x-1);

120 (× + 1) -2 (× + 1) (x-1) -120 (x-1) = 0;

Ife kuthetsa aone kuti pali:

(X ^ 2) = 121

Onani kuti pali mayankho ziwiri: + -11, ndipo -11 ngati 11 ndi kupereka lalikulu 121. Koma yankho lathu ndi inde, chifukwa liwiro la njinga yamoto alibe mtengo zoipa Choncho, akhoza kulembedwa Yankho: 11 mph . Choncho, ife tapeza kuchuluka chofunika, womwe ndi liwiro mu akadali madzi.

Tafotokoza options onse pa ntchito zoyenda tsopano mu lingaliro lawo muyenera alibe vuto ndi mavuto. Kuti athetse iwo, muyenera kudziwa zofunika chilinganizo ndi mawu monga "mlingo kutsekedwa ndi kuchotsa." Lezani mtima, anakhala ntchito izi, ndi bwino adzabwera.
