Kureba uye kutama - matambudziko nemhinduro

1. Mota inofamba mumugwagwa wakatwasuka 100 m kumabvazuva yozotevera 50 m kumadokero. Tsvaga daro uye kutama kwemota.

mhinduro Kure uye kutama - matambudziko nemhinduro 1

Kureba kwemamita zana + mamita makumi mashanu = mamita zana nemakumi mashanu

Kutamiswa kuri mamita zana - mamita makumi mashanu = mamita makumi mashanu, kumabvazuva.

2. Munhu anofamba mamita mana kumabvazuva, ozofamba mamita matatu kuchamhembe. Sarudza daro uye kutama.

mhinduro

Kure uye kutama - matambudziko nemhinduro 2

3. Mumhanyi anofamba-famba nenzira yerectangle ine urefu = mamita makumi mashanu uye upamhi = mamita makumi maviri. Mushure mekufamba-famba nenzira yerectangle kaviri, mumhanyi anodzokera panzvimbo yekutanga. Sarudza daro uye kutama.

mhinduro

Kutenderera kwerectangle = 2 (mamita makumi mashanu) + 2 (mamita makumi maviri) = mamita zana + mamita makumi mana = mamita zana nemakumi mana.

Inofamba ichitenderedza rectangle kaviri = 2 (mamita 140) = mamita 280.

Kureba = 280 m.

Kutamiswa = 0 m . ( mumhanyi anodzokera panzvimbo yekutanga)

4. Speedometer yemotokari inoti makiromita 10,500 pakutanga kwerwendo uye makiromita 10,700 kumagumo. Sarudza daro uye kutama.

mhinduro

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

Kutamiswa = 0 km. (mota inodzokera panzvimbo yekutanga)

1. Chii chinonzi daro? Mhinduro: Kureba ndiko kufamba kwese kwechinhu, zvisinei nekuti chakananga kupi.

2. Chii chinonzi kutama? Mhinduro: Kutama idaro diki pakati penzvimbo yekutanga neyekupedzisira yechinhu, negwara rakatarwa.

3. Kureba kunogona kuva kushoma pane kusimuka here? Mhinduro: Kwete. Kureba kunogara kuri kukuru kana kuti kwakaenzana nekusimuka.

4. Kana munhu akafamba-famba munzira yakatenderera obva asvika panzvimbo yekutanga, chii chinonzi kutama? Mhinduro: Kutama kunenge kuri zero nekuti nzvimbo dzekutanga nedzekupedzisira dzakafanana.

5. Ndezvipi zvikamu zvedaro uye displacement mu metric system? Mhinduro: Zvose zvinoyerwa mumamita (m).

6. Kuchinjana kunogona kuva negative here? Mhinduro: Ehe. Kuchinjana negative kunoratidza kuti divi rakapesana negwara rakanaka rakasarudzwa.

7. Kureba nekutama zvinomiririrwa sei muchimiro chevector? Mhinduro: Kureba ihuwandu hwe scalar uye hune hukuru chete. Kutama, sezvo iri vector, kune hukuru negwara.

8. Kana munhu akafamba mamita gumi kumabvazuva uyezve mamita gumi kumadokero, daro rose rakafukidzwa nderei uye daro rose raanofanira kufamba naro nderei? Mhinduro: Kureba = mamita makumi maviri; Kutama = mamita 0.

9. Chii chinoratidza kusachinja-chinja kwe zero? Mhinduro: Zvinoratidza kuti nzvimbo dzekutanga nedzekupedzisira dzakafanana.

10. Zvinokwanisika here kuti chinhu chifambe kana kufamba kwacho kuri zero? Mhinduro: Ehe. Chinhu chinofamba mudenderedzwa rakavharwa kana nzira inodzokera panzvimbo yacho yekutanga, zvichikonzera kusafamba kwe zero.

11. Avhareji yekumhanya inoverengwa sei? Mhinduro: Avhareji yekumhanya = Nhambwe yese yafambirwa / Nguva yese yatorwa.

12. Avhareji yekumhanya inoverengwa sei? Mhinduro: Avhareji yekumhanya = Kufamba kwese / Nguva yese inotorwa.

13. Chii chinorehwa negwara mukutama? Mhinduro: Kutama kunobatsira kunzwisisa mafambiro kubva pakutanga kusvika pakupedzisira.

14. Tinoratidza sei kutama mukufamba kwechikamu chimwe chete? Mhinduro: Mukufamba kwechikamu chimwe chete, kutama kunogona kumirirwa nehukuru hwakanaka kana husina kunaka, zvichienderana negwara rakasarudzwa.

15. Chii chingave chinhu chinokandwa mudenga chobva chadzokera kuruoko rweanokanda? Mhinduro: Kukandwa kwacho kwaizova zero nekuti nzvimbo dzekutanga nedzekupedzisira dzakafanana.

16. Hukuru hwekutama hunogona kukura kupfuura daro rakafambwa here? Mhinduro: Kwete. Hukuru hwekutama hunogona kuenzana kana kushoma pane daro, asi hahumbofi hwakakura.

17. Ndeipi basa rinoitwa nepfungwa yekutarisa kutama? Mhinduro: Pfungwa yekutarisa inobatsira kutsanangura nzvimbo yekutanga iyo kutama kunoverengerwa kubva.

18. Kana mota ichifamba yakatwasuka kwemakiromita makumi mashanu yozodzokera kwayakatanga, chii chinonzi kufamba kwayo? Mhinduro: Kufamba kwemota hapana.

19. Kureba kwenzira kunoreva chii kana tichitarisa kufamba? Mhinduro: Kureba kwenzira ishoko rekuti daro rakafambwa.

20. Ungasiyanisa sei daro nekufamba nemifananidzo? Mhinduro: Pagirafu, daro rinogara richimiririrwa nekakombama kasingaderedzi, nepo kufamba nekakombama kunogona kumiririrwa nekakombama kanowedzera, kanoderera, kana kuti kanoramba kakangofanana, zvichienderana nekwakatangira kufamba.

21. Zvinodiwa here kuti chinhu chifambe kuti chifambe? Mhinduro: Kwete. Chinhu chinogona kushanya kana nzvimbo yacho ikachinja, kunyangwe chikasafamba kwenguva yakati.

23. Kana nzira yose yakafukidzwa nechinhu yakakombama, mafambiro acho achiri daro pfupi here pakati penzvimbo dzekutanga nedzekupedzisira? Mhinduro: Ehe, mafambiro acho anogara ari daro remutsetse wakatwasuka pakati penzvimbo dzekutanga nedzekupedzisira.

24. Ndepapi mamiriro ezvinhu anogona kuva nehukuru hwakafanana? Mhinduro: Kana chinhu chichifamba mumutsara wakatwasuka pasina kuchinja gwara racho.

25. Chinhu chinogona kuva nekumhanya kunogara kwenguva refu uye kumhanya kunogara kwenguva refu here? Mhinduro: Ehe, kana chinhu chiri kufamba munzira yakakombama nekumhanya kunogara kwenguva refu, divi racho (uye nekudaro kumhanya kwaro) rinochinja, asi kumhanya kwaro kunoramba kuripo nguva dzose.

26. Kureba nekutama zvinobatana sei nenguva? Mhinduro: Kureba nekutama, kana zvikakamurwa nenguva, zvinopa avhareji yekumhanya uye avhareji yekumhanya, zvichiteerana.

27. Kureba kwechinhu kubva pane imwe poindi kunogona kuwedzera here ukuwo kufamba kwacho kuchiramba kwakafanana? Mhinduro: Kwete. Kana kufamba kwacho kukaramba kwakafanana, nzvimbo yechinhu ichi maererano nenzvimbo yekutanga haichinji, saka daro kubva pane imwe poindi harigone kuwedzera.

28. Kutama-tama ihuwandu hwe scalar here kana kuti huwandu hwe vector? Mhinduro: Kutama-tama ihuwandu hwe vector.

29. Sei tisingakwanise kuwedzera daro zvakananga kuti tiwane mhinduro yakaita se displacements? Mhinduro: Nekuti daro harina gwara, rinomiririra hukuru chete. Displacements dzine hukuru uye gwara, saka dzinogona kuwedzerwa nenzira ye vectorially.

30. Kufamba kwedenderedzwa kwakaenzana nedenderedzwa redenderedzwa mukufamba kupi? Mhinduro: Mukufamba kwedenderedzwa, kana kutenderera kamwe chete kwakaitwa, daro rakaenzana nedenderedzwa, asi kufamba kwedenderedzwa izero. Kana kufamba kwacho kwakafukidza hafu chaiyo yedenderedzwa, kufamba kwedenderedzwa (mutsetse wakatwasuka kuburikidza nedhayamita yedenderedzwa) kwaizoenzana neradius yedenderedzwa.
