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 lingamamitha ayi-100amamitha angu-50 = amamitha angu-150

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 uhambahamba isikwele ithrekhi eno-lububanzi = amamitha angu-50 kanti ububanzi = amamitha angu-20. Ngemva kohambo azungeze isikwele ithrekhi izikhathi ezimbili, umgijimi abuyele endaweni yokuqala. 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 nxazonke kwesikwele izikhathi ezimbili = 2 (amamitha ayi-140) = amamitha angama-280.

Ibanga = 280 m.

Ukufuduka = 0 m. (i 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. (ukubuya kwemoto kuya endaweni yokuqala)

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

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

3. Ingabe ibanga lingaze libe ngaphansi kokufuduka? Impendulo: Cha. Ibanga lihlala likhulu noma lilingana nokususwa.

4. Uma umuntu ehamba emzileni ojikelezayo bese efika lapho eqala khona, kuyini ukufuduka? Impendulo: Ukufuduka ku-zero ngoba izikhundla zokuqala nezokugcina ziyafana.

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

6. Ingabe ukufuduka kungaba yinto embi? Impendulo: Yebo. Ukushintshashintsha okungekuhle kubonisa ukuthi isiqondiso siphambene nesiqondiso esihle esikhethiwe.

7. Ibanga kanye nokufuduka kwethulwa kanjani ngesimo se-vector? Impendulo: Ibanga liyinani elilinganiselwe futhi linobukhulu kuphela. Ukufuduka, njengoba kuyi-vector, kunobukhulu kanye nesiqondiso.

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

9. Kusho ukuthini ukufuduka okungu-zero? Impendulo: Kubonisa 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 ekungahambini nhlobo.

11. Ijubane elimaphakathi libalwa 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: Indlela yokusuka isuka endaweni ethile iyasiza ekuqondeni indlela yokunyakaza kusukela endaweni yokuqala kuya endaweni yokugcina.

14. Sikubonisa kanjani ukufuduka ekunyakazeni okunezinhlangothi ezimbili? Impendulo: Ekunyakazeni okunezinhlangothi eyodwa, ukufuduka kungamelwa yinani elihle noma elibi, kuye ngokuthi isiqondiso sikhethiwe.

15. Kungaba yini ukufuduka kwanoma iyiphi into ephonswe phezulu bese ibuyela esandleni somjikijeli? 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 bungabi ngaphezu kwalokho.

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

18. Uma imoto ihamba ngomugqa oqondile amakhilomitha angu-50 bese ibuyela lapho iqala khona, iyini indlela eshintsha ngayo? Impendulo: Ukufuduka kungu-zero.

19. Bungakanani ubude bendlela ngokwesimo sokunyakaza? Impendulo: Ubude bendlela bungenye igama elisho ibanga elihanjiwe.

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

21. Ingabe kuyadingeka ukuthi into ihambe ukuze kube nokugudluzwa? Impendulo: Cha. Into ingaba nokuguquguquka 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 kuhlale kuyibanga eliqondile phakathi kwamaphuzu okuqala nawokugcina.

24. Kukuziphi izimo lapho ibanga kanye nokufuduka kungaba nobukhulu obufanayo khona? Impendulo: Uma into ihamba ngendlela eqondile ngaphandle kokushintsha indlela yayo.

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

26. Ibanga kanye nokufuduka kuhlobana kanjani nesikhathi? Impendulo: Ibanga kanye nokunyakaza, 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 elisuka endaweni alikwazi ukwanda.

28. Ingabe ukufuduka kuyinani le-scalar noma le-vector? Impendulo: Ukufuduka kuyinani le-vector.

29. Kungani singenakwengeza amabanga ngqo ukuze sithole umphumela ofana nokufuduka? Impendulo: Ngenxa yokuthi ibanga alinaso isiqondiso, limelela ubukhulu kuphela. Ukufuduka kunesilinganiso kanye nesiqondiso, ngakho-ke kungangezwa ngendlela ye-vector.

30. Kukuyiphi intshukumo lapho ukufuduka kulingana khona nomjikelezo wendilinga? Impendulo: Ekuhambeni okujikelezayo, uma kwenziwa ukujikeleza okukodwa okuphelele, ibanga lilingana nomjikelezo, kodwa ukuguquguquka kungu-zero. Kuphela uma ukunyakaza kumboza ingxenye yendilinga, ukuguquguquka (umugqa oqondile odlula ububanzi bendilinga) kuzolingana nobubanzi bendilinga.
