Sei kubata inofamba mabasa? Nzira dzokupedza yomumugwagwa matambudziko

Masvomhu - refu yakaoma nyaya, asi paboka yechikoro zvichaita kuenda kuburikidza zvose. Kunyanya kunetseka vadzidzi akakonzera dambudziko iri rakaramba. Kugadzirisa pasina matambudziko, uye vazhinji aipedza nguva, tarisa ino.

Cherechedza kuti kana iwe tsika, ipapo mabasa aya haungavhenekeri chero matambudziko. Process mhinduro inogona okurega automatism.

mhando

Chii chinorehwa kwakadai basa? Zviri nyore uye nyore mabasa, izvo zvinosanganisira zvinotevera mhando:

• motokari dzinenge dzichiuya;
• kutevedza;
• Movement negwara risiri;
• motokari kurwizi.

Tinopa kuita zvose kuti funga ariega. Chokwadi, tichava nekukatanura chete mienzaniso. Asi tisati ita mubvunzo sei kugadzirisa dambudziko iri inofamba, zvakakodzera kupinda inonyatsoita kuti tinoda mukubata zvachose vose aiitwa ichi mhando.

Formula: S = V * t. A shoma tsananguro: S - ndiye nzira, tsamba V anoreva velocity, uye tsamba T ndiyo nguva. tsika All chinogona kutaurwa Pakuurayiwa fomura. Nokudaro, nokukurumidza ndiyo nzira vakakamurwa nguva, uye nenguva - ndiyo nzira, vakakamurwa nokukurumidza.

mufambo vakananga

It ndicho mhando mabasa. Kuti tinzwisise chisarudzo, funga nezvomuenzaniso zvinotevera. Conditions: "mamwe mabhasikoro vaviri vaifamba panguva imwe chete kune mumwe, gwara paimba imwe neimwe ndizvo 100 km chii daro mhiri maminitsi 120, kana inozivikanwa kuti velocity pamusoro - 20 km paawa, uye wechipiri - gumi.". Tava kutendeukira kune mubvunzo sei kugadzirisa dambudziko iri cyclists.

Kuti aite izvi tinofanira anosuma mumwe rokuti, "mukuvhara nokukurumidza". In muenzaniso wedu, zvichaita akaenzana? Km 35 paawa (20 makiromita paawa + 15 km paawa). Izvi zvichava chiito chokutanga kugadzirisa dambudziko. Next, muwande maviri wokugumisa velocity sezvo vachifambira maviri o'clock: 35 * 2 = 70? Km. Takaona daro kuti cyclists tichaswedera maminitsi 120. Zvazvinosarira yokupedzisira chiito: 100-70 = 30 makiromita. kukarukureta ichi, takawana kure pakati cyclists. Pindura: 30 km.

Kana iwe havanzwisisi kugadzirisa dambudziko iri pakaunda-sangano, vachishandisa nzira kumhanya, shandisa rimwe chisarudzo.

Nzira yechipiri

Chokutanga, tinowana nzira kuti vakapfuura wokutanga nyanzvi yokuchovha bhasikoro: 20 * 2 = 40 makiromita. Nzira 2nd shamwari: gumi nemashanu kane maviri, akaenzana matatu makiromita. Peta kure vaifamba rokutanga uye rechipiri nyanzvi yokuchovha bhasikoro: 40 + 30 = 70 makiromita. Tinoziva iyo nzira kukurira pamwechete, saka vakasiya zvose nzira zvaiyambuka Bvisa: 100-70 = 30 km. Pindura: 30 km.

Takurukura mhando inofamba matambudziko okutanga. How kuagadzirisa, zviri ikozvino pachena, mberi kune inotevera kuona.

Countermovement

Condition: "Kubva imwe mink negwara risiri vaitasva hares maviri okutanga nokukurumidza - makiromita 40 paawa, uye wechipiri - 45 kph How kure vava kubva mumwe mumaawa maviri ..?"

Pano, sezvo ari yapfuura muenzaniso, pane dzinobvira maviri. Mune wokutanga, tichaita chimwe chinhu yaizivikanwa nzira:

1. Nzira yokutanga tsuro: 40 * 2 = 80.
2. Nzira yechipiri tsuro: 45 * 2 = 90? Km.
3. The nzira kuti vakaenda pamwe chete: 80 + 90 = 170? Km. Pindura: 170? Km.

Asi pane imwe nzira.

kubviswa zvazvingava

Sezvo imi kare wafungidzira, muchimiro ichi, zvakafanana wokutanga, pachava itsva izwi. Funga zvinotevera mhando inofamba matambudziko, sei kuagadzirisa tichibatsirwa kwavatapwa unodiwa.

Her tiri pakutanga uye tinowana: 40 + 45 = 85 makiromita paawa. Zvazvinosarira kuona zviri kure anoparadzanisa pavo, nekuti zvose Data vari kare anozivikanwa: 85 * 2 = 170? Km. Pindura: 170? Km. Tataura mhinduro matambudziko pamusoro inofamba iri chinyakare nzira, uyewo nokuvhara nokukurumidza uye kubviswa.

mufambo pashure

Ngatimboonai muenzaniso dambudziko uye edza kugadzirisa nayo pamwe chete. Condition: ". Schoolboys vaviri, Cyril uye Anton, vakasiya chikoro uye akatamira ari kumhanya 50 metres paminiti Kostya akavasiya maminitsi matanhatu panguva kumhanya 80 metres paminiti Papera nguva kuchauya Konstantin Cyril uye Anton.?"

Saka, sei kugadzirisa matambudziko ari inofamba pashure? Pano tinofanira kumhanya kusvika. Chete muchiitiko ichi hakufaniri kuwedzerwa, uye subtracted: 80-50 = 30 mamita paminiti. The chiito yechipiri vachaziva kuti mamita akawanda anotsaura kuchikoro mafupa goho. Kuti izvi zvidaro, 50 * 6 = 300 metres. Wokupedzisira chiito tinowana nguva apo Kostya kubata Cyril uye Anton. To nzira iyi 300 metres inofanira kugoverwa yokupedzisira kumhanya mamita 30 paminiti: 300: 30 = maminitsi 10. Pindura: pashure maminitsi 10.

zvakawanikwa

Zvichienderana hurukuro pamusoro apa, zvinokwanisika kuzochera mhedziso:

• kana nekugadzirisa motokari iri nyore kushandisa mwero convergence uye kubviswa;
• kana chiri pakaunda-inofamba kana uchifamba oga, tsika idzi nokuwedzera kuti velocities zvinhu;
• Kana basa pamberi pedu pamusoro sangano vachidzingirira, ipapo kudya chiito rwakatarisana Uyezve, kuti ndiye kubvisa.

Takurukura vamwe mabasa parwendo, sei kubata, akanzwisisa, vakazoguma vaiziva pfungwa ye "wokugumisa nokukurumidza" uye "kubviswa zvazvingava", zvazvinosarira kufunga chokupedzisira pfungwa, kureva sei kugadzirisa matambudziko ari kufamba erwizi?

kosi

Apo unogona kusangana zvakare:

• mabasa nokuti kufamba kune mumwe;
• Bato vachidzingirira;
• Movement iri negwara.

Asi kusiyana yapfuura mabasa, rwizi une zvinoyerera velocity kuti hazvigoni kungotariswa. Pano, zvinhu kuchaita kana murwizi - ipapo ichi zvazvingava anofanira kuwedzerwa kuna pachake kumhanya zvinhu, kana pamusoro kuerera - zvakakosha bvisa kubva kumhanya ari chinhu.

Muenzaniso dambudziko pamusoro inofamba erwizi

Condition: "Jet akaenda aibuda ari kumhanya makiromita 120 paawa uye vakadzoka, uye nguva maawa asingasviki maviri, pane kurwisa kuerera chii kumhanya watercraft amire mvura.?" Tinopiwa nokuyerera zvazvingava akaenzana kiromita imwe paawa.

We avapo chisarudzo. Tinopa kusika munhu chati nokuda kuona muenzaniso. Ngatitore mudhudhudhu nokukurumidza mune mira mvura X, ipapo kumhanya kuerera akaenzana X + 1 uye x-1 pamusoro. Distance kumativi rwendo ari 120? Km. Zvakaratidza kuti nguva akatorwa kufamba pamusoro aibuda 120 (x-1), uye kuerera 120 (x + 1). Zvinozivikanwa kuti 120 (x-1) kwemaawa maviri idukusa 120 (x + 1). Zvino tinogona anozodzidza achizadza patafura.

Chii tine: (120 / (1-x)) - 2 = 120 / (x + 1) nekuwanza chikamu chimwe nechimwe pasi (x + 1) (x-1);

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

We vagadzirise mukana wokuti vanhu vanga:

(X ^ 2) = 121

Ona kuti pane mhinduro zviviri zvinokwanisika: + -11, uye -11 sezvo 11 uye kupa pachivara 121. Asi mhinduro yedu iri hungu, nekuti kumhanya pamusoro mudhudhudhu angasava vasingadi ukoshi, saka, unogona kunyorwa mhinduro: 11 mph . Saka, isu ndawana raida mari, kureva nokukurumidza mune vachiri mumvura.

Takurukura nzira dzose pamusoro inofamba mabasa zvino pachisarudzo chavo unofanira kuva matambudziko nezvinetso. Kuagadzirisa, unofanira kuziva inokosha payakavakirwa uye mazwi akadai "kuvhara mwero uye kubviswa." Shivirira, akapedza mabasa aya, uye kubudirira achauya.
