Kutalikirana ndi kusamuka - mavuto ndi mayankho

1. Galimoto imayenda mumsewu wowongoka mamita 100 kum'mawa kenako mamita 50 kumadzulo. Pezani mtunda ndi kusuntha kwa galimotoyo.

Anakonza Kutalikirana ndi kusamuka - mavuto ndi mayankho 1

Mtunda ndi mamita 100 + mamita 50 = mamita 150

Malo osamukira ndi mamita 100 - mamita 50 = mamita 50, kum'mawa.

2. Munthu amayenda mamita 4 kum'mawa, kenako amayenda mamita 3 kumpoto. Dziwani mtunda ndi kusuntha.

Anakonza

Kutalikirana ndi kusamuka - mavuto ndi mayankho 2

3. Wothamanga amayenda mozungulira njira ya rectangle kutalika = mamita 50 ndipo m'lifupi = mamita 20. Atayenda mozungulira njira ya rectangle kawiri, wothamanga amabwerera komwe anayambira. Dziwani mtunda ndi kusuntha.

Anakonza

Mzere wozungulira wa rectangle = 2 (mamita 50) + 2 (mamita 20) = mamita 100 + mamita 40 = mamita 140.

Amayenda mozungulira bwalo lamakona anayi kawiri = 2 (mamita 140) = mamita 280.

Mtunda = 280 m.

Kusamuka = 0 m . ( wothamanga abwerera komwe amayambira)

4. Speedometer ya galimoto imawerengera makilomita 10,500 kumayambiriro kwa ulendo ndi makilomita 10,700 kumapeto. Dziwani mtunda ndi kusuntha.

Anakonza

Mtunda = 10,700 km - 10,500 km = 200 km.

Kusamuka = 0 km. (galimoto yabwerera komwe idayambira)

1. Kodi mtunda ndi chiyani? Yankho: Mtunda ndi kayendedwe konse ka chinthu, mosasamala kanthu za komwe chili.

2. Kodi kusamuka n’chiyani? Yankho: Kusamuka ndi mtunda waufupi kwambiri pakati pa malo oyamba ndi omaliza a chinthu, ndi njira yodziwika bwino.

3. Kodi mtunda ungakhale wochepa kuposa kusuntha? Yankho: Ayi. Nthawi zonse mtunda umakhala wokulirapo kapena wofanana ndi kusuntha.

4. Ngati munthu ayenda mozungulira njira yozungulira kenako n’kufika poyambira, kodi kusunthaku ndi chiyani? Yankho: Kusunthaku ndi zero chifukwa malo oyamba ndi omaliza ndi ofanana.

5. Kodi mayunitsi a mtunda ndi kusamuka mu dongosolo la metric ndi ati? Yankho: Onsewa amayesedwa mu mamita (m).

6. Kodi kusamuka kungakhale koipa? Yankho: Inde. Kusamuka koipa kumasonyeza kuti njirayo ndi yosiyana ndi njira yabwino yosankhidwa.

7. Kodi mtunda ndi kusamuka zimaimiridwa bwanji mu mawonekedwe a vekitala? Yankho: Mtunda ndi kuchuluka kwa scalar ndipo kumakhala ndi kukula kokha. Kusamuka, pokhala vekitala, kumakhala ndi kukula ndi komwe kukupita.

8. Ngati munthu ayenda mamita 10 kum'mawa kenako mamita 10 kumadzulo, kodi mtunda wonse womwe watengedwa ndi wotani komanso kusamuka konse ndi kotani? Yankho: Mtunda = mamita 20; Kusamuka = mamita 0.

9. Kodi kusamuka kwa zero kumasonyeza chiyani? Yankho: Kumasonyeza kuti malo oyamba ndi omaliza ndi ofanana.

10. Kodi n'zotheka kuti chinthu chiziyenda ngati kusamuka kwake kuli zero? Yankho: Inde. Chinthu chomwe chikuyenda mozungulira kapena njira yotsekedwa chimabwerera pamalo ake oyambira, zomwe zimapangitsa kuti ziro zisamayende.

11. Kodi liwiro lapakati limawerengedwa bwanji? Yankho: Liwiro lapakati = Mtunda wonse woyenda / Nthawi yonse yomwe yatengedwa.

12. Kodi liwiro la avareji limawerengedwa bwanji? Yankho: Avereji ya liwiro = Kusuntha konse / Nthawi yonse yomwe yatengedwa.

13. Kodi kufunika kwa njira yoyendetsera zinthu ndi kotani? Yankho: Njira yoyendetsera zinthu imathandiza kumvetsetsa komwe kayendedwe ka zinthu kamayambira pamalo oyamba mpaka omaliza.

14. Kodi timatanthauza bwanji kusamuka mu kayendedwe ka mbali imodzi? Yankho: Mu kayendedwe ka mbali imodzi, kusamuka kumatha kuyimiridwa ndi mtengo wabwino kapena woipa, kutengera njira yosankhidwa.

15. Kodi chinthu chilichonse chomwe chaponyedwa mmwamba kenako n’kubwerera m’manja mwa woponyayo chingakhale chotani? Yankho: Kusunthako kungakhale zero chifukwa malo oyambira ndi omalizira ndi ofanana.

16. Kodi kukula kwa kusamuka kungakhale kwakukulu kuposa mtunda woyenda? Yankho: Ayi. Kukula kwa kusamuka kungakhale kofanana kapena kocheperapo kuposa mtunda, koma sikungakhale kwakukulu.

17. Kodi mfundo yofotokozera imagwira ntchito yotani pozindikira kusamuka? Yankho: Mfundo yofotokozera imathandiza kufotokoza malo oyamba omwe kusamuka kumawerengedwa.

18. Ngati galimoto iyenda molunjika kwa makilomita 50 kenako n’kubwerera komwe inayambira, kodi imayenda bwanji? Yankho: Kuyenda kwake ndi zero.

19. Kodi kutalika kwa njira ndi kotani poganizira za kuyenda? Yankho: Kutalika kwa njira ndi mawu ena otanthauza mtunda woyenda.

20. Kodi mungasiyanitse bwanji mtunda ndi kusuntha pogwiritsa ntchito zithunzi? Yankho: Pa graph, mtunda nthawi zonse umaimiridwa ndi curve yosatsika, pomwe kusuntha kumatha kuyimiridwa ndi curve yomwe imawonjezeka, imachepa, kapena imakhalabe yokhazikika, kutengera komwe mayendedwe akuyendera.

21. Kodi ndikofunikira kuti chinthu chiziyenda kuti chikhale ndi malo osuntha? Yankho: Ayi. Chinthu chingakhale ndi malo osuntha ngati malo ake asintha, ngakhale chitakhala kuti sichikuyenda kwa nthawi yayitali.

23. Ngati njira yonse yophimbidwa ndi chinthu ndi yokhota, kodi kusunthaku kudakali mtunda waufupi kwambiri pakati pa malo oyambira ndi omalizira? Yankho: Inde, kusunthaku nthawi zonse kumakhala mtunda wowongoka pakati pa malo oyambira ndi omalizira.

24. Ndi nthawi ziti zomwe mtunda ndi kusamuka kwake zingakhale ndi kukula kofanana? Yankho: Pamene chinthu chikuyenda molunjika popanda kusintha njira yake.

25. Kodi chinthu chingakhale ndi liwiro losasintha komanso liwiro losintha? Yankho: Inde, ngati chinthucho chikuyenda m'njira yokhota pa liwiro losasintha, komwe chikupita (ndipo motero liwiro) limasintha, koma liwiro lake limakhalabe losasintha.

26. Kodi mtunda ndi kusamuka zimagwirizana bwanji ndi nthawi? Yankho: Mtunda ndi kusamuka, zikagawidwa ndi nthawi, zimapereka liwiro lapakati ndi liwiro lapakati, motsatana.

27. Kodi mtunda wa chinthu kuchokera pa mfundo ungawonjezeke pomwe kusuntha kwake kumakhala kosasintha? Yankho: Ayi. Ngati kusuntha kumakhala kosasintha, malo a chinthucho poyerekeza ndi poyambira sasintha, kotero mtunda wochokera pa mfundo sungawonjezeke.

28. Kodi kusamuka ndi kuchuluka kwa scalar kapena vekitala? Yankho: Kusamuka ndi kuchuluka kwa vekitala.

29. N’chifukwa chiyani sitingathe kuwonjezera mtunda mwachindunji kuti tipeze zotsatira monga kusuntha? Yankho: Chifukwa mtunda ulibe njira, umangoyimira kukula kwake. Kusuntha kuli ndi kukula ndi njira, kotero kumatha kuwonjezedwa mwa vectorially.

30. Kodi kuyenda kozungulira ndi kotani komwe kumayenda kofanana ndi kuzungulira kwa bwalo? Yankho: Mu kuyenda kozungulira, ngati kuzungulira konse kwachitika, mtunda umakhala wofanana ndi kuzungulira, koma kuyendako ndi zero. Pokhapokha ngati kuyendako kukuphimba theka lenileni la bwalo, kuyendako (mzere wowongoka kudzera m'mimba mwake mwa bwalo) kungakhale kofanana ndi utali wa bwalo.
