Ibanga kanye nokufuduka - izinkinga nezixazululo

1. Imoto ihamba ngomgwaqo oqondile ngamamitha ayi-100 empumalanga bese kuba ngamamitha angama-50 entshonalanga. Thola ibanga kanye nokufuduka kwemoto.

Isixazululo Ibanga kanye nokufuduka - izinkinga nezixazululo 1

Ibanga liyi-100 metres + 50 metres = 150 metres

Indawo yokufuduka ingamamitha ayi-100 - amamitha angu-50 = amamitha angu-50, ngasempumalanga.

2. Umuntu uhamba amamitha angu-4 empumalanga, bese ehamba amamitha angu-3 enyakatho. Thola ibanga kanye nokufuduka.

Isixazululo

Ibanga kanye nokufuduka - izinkinga nezixazululo 2

3. Umgijimi uhamba ezungeze ithrekhi engunxande ubude = amamitha angu-50 nobubanzi = amamitha angu-20. Ngemva kokuhamba ezungeze ithrekhi engunxande kabili, umgijimi ubuyela lapho eqala khona. Thola ibanga kanye nokufuduka.

Isixazululo

Ukujikeleza kwesikwele = 2 (amamitha angu-50) + 2 (amamitha angu-20) = amamitha ayi-100 + amamitha angu-40 = amamitha angu-140.

Uhamba ezungeze unxande izikhathi ezimbili = 2 (amamitha ayi-140) = amamitha angama-280.

Ibanga = 280 m.

Ukufuduka = 0 m . ( umgijimi ubuyela endaweni yokuqala)

4. I-speedometer yemoto ifunda amakhilomitha ayi-10,500 ekuqaleni kohambo kanye namakhilomitha ayi-10,700 ekugcineni. Thola ibanga kanye nokufuduka.

Isixazululo

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

Ukufuduka = 0 km. (imoto ibuyela endaweni yokuqala)

1. Liyini ibanga? Impendulo: Ibanga liwukuhamba okuphelele kwento, kungakhathaliseki ukuthi iqondephi.

2. Kuyini ukufuduka? Impendulo: Ukufuduka ibanga elifushane kakhulu phakathi kwendawo yokuqala neyokugcina yento, enesiqondiso esithile.

3. Ingabe ibanga lingaba ngaphansi kokufuduka? Impendulo: Cha. Ibanga lihlala likhulu noma lilingana nokufuduka.

4. Uma umuntu ehambahamba emzileni ojikelezayo bese efika lapho eqala khona, kuyini ukufuduka? Impendulo: Ukufuduka kuyiziro ngoba izikhundla zokuqala nezokugcina ziyafana.

5. Yiziphi amayunithi ebanga kanye nokuguquguquka ohlelweni lwe-metric? Impendulo: Zombili zilinganiswa ngamamitha (m).

6. Ingabe ukufuduka kungaba yinto engemihle? Impendulo: Yebo. Ukufuduka okungemihle kubonisa ukuthi isiqondiso siphambene nesiqondiso esihle esikhethiwe.

7. Ibanga kanye nokususwa kwesimo kuvezwa kanjani ngesimo sevektha? Impendulo: Ibanga liyinani le-scalar futhi linobukhulu kuphela. Ukususwa kwesimo, njengoba kuyivektha, kunobukhulu kanye nesiqondiso.

8. Uma umuntu ehamba amamitha ayi-10 empumalanga bese ehamba amamitha ayi-10 entshonalanga, lingakanani ibanga elihlanganisiwe kanye nokufuduka okuphelele? Impendulo: Ibanga = amamitha angama-20; Ukufuduka = amamitha ayi-0.

9. Kusho ukuthini ukufuduka okungu-zero? Impendulo: Kusho ukuthi izikhundla zokuqala nezokugcina ziyafana.

10. Kungenzeka yini ukuthi into ihambe uma ukufuduka kwayo kungu-zero? Impendulo: Yebo. Into ehamba ngeluphu evaliwe noma endleleni ibuyela endaweni yayo yokuqala, okuholela ekufudukeni okungu-zero.

11. Isivinini esimaphakathi sibalwa kanjani? Impendulo: Isivinini esimaphakathi = Ibanga eliphelele elihanjiwe / Isikhathi esiphelele esithathiwe.

12. Ijubane elimaphakathi libalwa kanjani? Impendulo: Ijubane elimaphakathi = Ukufuduka okuphelele / Isikhathi esiphelele esithathiwe.

13. Kubaluleke ngani ukuqondiswa kokuhamba? Impendulo: Ukuqondiswa kokuhamba kusiza ekuqondeni ukuqondiswa kokuhamba kusukela ekuqaleni kuya endaweni yokugcina.

14. Sikubonisa kanjani ukufuduka ekunyakazeni okunohlangothi olulodwa? Impendulo: Ekunyakazeni okunohlangothi olulodwa, ukufuduka kungamelwa yinani elihle noma elibi, kuye ngokuthi kukhethwe kanjani isiqondiso.

15. Kungaba yini ukufuduka kwanoma iyiphi into ephonswe phezulu bese ibuyela esandleni somjikisi? Impendulo: Ukufuduka kungaba yi-zero ngoba izikhundla zokuqala nezokugcina ziyafana.

16. Ingabe ubukhulu bokufuduka bungaba bukhulu kunebanga elihanjiwe? Impendulo: Cha. Ubukhulu bokufuduka bungalingana noma bube ngaphansi kwebanga, kodwa bungalokothi bube bukhulu.

17. Iyiphi indima edlalwa yiphuzu lokubhekisela ekunqumeni ukufuduka? Impendulo: Iphuzu lokubhekisela lisiza ekuchazeni indawo yokuqala lapho ukufuduka kubalwa khona.

18. Uma imoto ihamba ngomugqa oqondile amakhilomitha angu-50 bese ibuyela lapho iqala khona, iyini i-displacement yayo? Impendulo: I-displacement ingu-zero.

19. Buyini ubude bendlela uma kukhulunywa ngokunyakaza? Impendulo: Ubude bendlela bungenye igama elichaza ibanga elihanjiwe.

20. Ungahlukanisa kanjani ibanga kanye nokushintshashintsha ngemidwebo? Impendulo: Kugrafu, ibanga lihlala limelelwa yijika elinganciphisi, kuyilapho ukufuduka kungamelelwa yijika elikhuphukayo, elinciphayo, noma elihlala lingaguquki, kuye ngokuthi ukunyakaza kuhamba kanjani.

21. Ingabe kuyadingeka ukuthi into ihambe ukuze ibe nokunyakaza? Impendulo: Cha. Into ingaba nokunyakaza uma indawo yayo ishintsha, noma ngabe ayihambi isikhathi esithile.

23. Uma indlela iyonke embozwe yinto igobile, ingabe ukufuduka kuseyibanga elifushane kakhulu phakathi kwamaphuzu okuqala nawokugcina? Impendulo: Yebo, ukufuduka kuhlala kuyibanga lomugqa oqondile phakathi kwamaphuzu okuqala nawokugcina.

24. Kukuziphi izimo lapho ibanga kanye nokufuduka kungaba nobukhulu obufanayo khona? Impendulo: Lapho into ihamba emgqeni oqondile ngaphandle kokushintsha indlela yayo.

25. Ingabe into ingaba nesivinini esingaguquki kanye nesivinini esishintshayo? Impendulo: Yebo, uma into ihamba endleleni egobile ngesivinini esingaguquki, isiqondiso sayo (ngakho-ke isivinini) siyashintsha, kodwa isivinini sayo sihlala singaguquki.

26. Ibanga kanye nokufuduka kuhlobana kanjani nesikhathi? Impendulo: Ibanga kanye nokufuduka, uma kuhlukaniswa ngesikhathi, kunikeza isivinini esimaphakathi kanye nesivinini esimaphakathi, ngokulandelana.

27. Ingabe ibanga lento ukusuka ephuzwini linganda kuyilapho ukufuduka kwayo kuhlala kungaguquki? Impendulo: Cha. Uma ukufuduka kuhlala kungaguquki, indawo yento maqondana nendawo yokuqala ayishintshi, ngakho ibanga ukusuka endaweni alikwazi ukwanda.

28. Ingabe ukufuduka kuyi-scalar noma i-vector quantity? Impendulo: Ukufuduka kuyi-vector quantity.

29. Kungani singenakwengeza amabanga ngqo ukuze sithole umphumela ofana nokufuduka? Impendulo: Ngenxa yokuthi ibanga alinawo umhlahlandlela, limelela ubukhulu kuphela. Ukufuduka kunezinkulu kanye nesiqondiso, ngakho-ke kungangezwa ngokwe-vector.

30. Kukuyiphi intshukumo lapho ukufuduka kulingana nomjikelezo wendilinga? Impendulo: Ekushukumeni okujikelezayo, uma kwenziwa ukujikeleza okukodwa okuphelele, ibanga lilingana nomjikelezo, kodwa ukufuduka kungu-zero. Kuphela uma ukunyakaza kumboza ingxenye yendilinga, ukufuduka (umugqa oqondile phakathi kobubanzi bendilinga) kuzolingana nomugqa wendilinga.
