I-ukunyakaza komugqa ofanayo (MRU) Kuyinto ukunyakaza okwenziwa kulayini oqondile, ngejubane elingaguquki (ngobukhulu obuqhubekayo nokuqondisa).
Indlela ibizwa ngokuthi yindlela echazwa into lapho isuka kwelinye iphuzu iye kwelinye. I-Physics ihlukanisa ukunyakaza nge-trajectory yabo:
Ukulungiswa kabusha. Kwenziwa ohlangothini olulodwa kuphela.
- Iyunifomu. Ijubane lihlala njalo, ukushesha kwalo akulona iqanda.
- Kuyashesha. Ukushesha okuqhubekayo, okusho ukuthi ijubane liyakhuphuka noma linciphe ngendlela engaguquki.
Igobile.
- Okubhaliwe. Kuyinto ukunyakaza kwe-oscillatory, njengaleyo ye-pendulum.
- Isiyingi. Nge-axis yokujikeleza kanye nerediyasi engaguquguquki. Indlela yokunyakaza ichaza umjikelezo.
- Ukufaniswa. Indlela yento idweba i-parabola.
Ukuthi ukunyakaza kufana kusho ukuthi ijubane layo lihlala njalo, ijubane aliguquki. Ukusheshisa kunguziro.
Isivinini ubuningi obuchazwa njengebanga elihanjiwe kuyunithi yesikhathi. Isibonelo: amakhilomitha angama-40 ngehora kusho ukuthi iselula ihamba amakhilomitha angama-40 ngehora (40 km / h).
Ukubala ibanga elihanjiwe ngento enokunyakaza okufana nomugqa, kusetshenziswa idatha elandelayo: isivinini nesikhathi.
Uma ulazi ibanga nejubane kepha ufuna ukubala isikhathi esizothatha, hlukanisa ibanga ngejubane:
d / v = t50 km / 100 km / h = 1/2 h (0.5 h)
Ungathola futhi ijubane uma unedatha yebanga nesikhathi:
D / t = V50 km / ½ h = 100 km / h
Ngamanye amagama, izici zokunyakaza okufana nomugqa (MRU) yilezi:
- Indlela eqondile
- Ijubane eliqhubekayo (iyunifomu)
- Ukusheshisa iZero
- Ukuqondiswa okuqhubekayo
- Bona futhi: Ukuwa kwamahhala nokuphonsa mpo
Izibonelo zokunyakaza okufana nxazonke
- Isitimela sisuka eParis ngo-6 ekuseni sifike eLyon ngo-8 ekuseni. Umzila wayo ulayini oqondile. Ibanga eliphakathi kweGare de Paris neGare de Lyon lingama-400 km. Isitimela sihamba njalo ngejubane elifanayo, ngaphandle kokusheshisa noma ukubopha amabhuleki size sifike lapho siya khona. Isitimela sihamba ngesivinini esingakanani?
Ibanga: 400 km
Isimo sezulu: 8 amahora - 6 amahora = 2 amahora
400 km / 2 hrs = 200 km / h
Phendula: isitimela sihamba ngamakhilomitha angama-200 ngehora.
- Umzila osuka endlini yami uye endlini yomngani wami ulayini oqondile. Noma nini lapho ngiyivakashela, ngishayela imoto yami ngejubane lamakhilomitha angama-20 ngehora, ngaphandle kokusheshisa noma ukwehlisa ijubane ngize ngifike lapho. Kungithatha isigamu sehora ukufika lapho.
Ikude kangakanani indlu yomngani wami?
Ijubane: 20 km / h
Isimo sezulu: 1/2 h
20 km / h / 1/2 h = 10 km
Phendula: Indlu yomngani wami iqhele ngamakhilomitha ayishumi.
- UJuan uhambisa amaphephandaba endaweni yangakubo. Njengoba ewazi amakheli ngekhanda, ugibela ibhayisikili lakhe futhi enze indlela yakhe ngaphandle kokuma lapho efika endlini ngayinye, kunalokho uphonsa amaphephandaba ebhayisikili. Indlela kaJuan isemgwaqweni owodwa oqondile, wamakhilomitha ama-2. Ihamba ngejubane lamakhilomitha ayi-10 ngehora. UJuan kufanele aqale uhambo bese ebuyela emuva ngomgwaqo ofanayo ngejubane elifanayo. Uma uJuan ehamba manje, kuzothatha isikhathi esingakanani ukubuya?
Kulokhu kuneminyakazo emibili yomugqa ofanayo: eyodwa iyahamba naleyo emuva.
Ijubane: 10 km / h
Ibanga: 2 km
2 km / 10 km / h = 0.2 h = imizuzu eyi-12
Lokhu kubalwa kungokwesinye sezivakashi.
Imizuzu eyi-12 x 2 (uhambo lokuya nokubuya) = imizuzu engama-24
Phendula: UJuan uzothatha imizuzu engama-24 ukubuya.
- Njalo ekuseni ngigijima amakhilomitha ayishumi ngiqonde ngasogwini lolwandle, futhi kungithatha ihora elilodwa. Ngifuna ukukhuphula ijubane lami ukuze ngidlale umncintiswano engiqhudelana nalowo engincintisana naye, ogijima kumakhilomitha ayi-12 ngehora. Kungithatha isikhathi esingakanani ukwenza uhambo lwami olujwayelekile ukuze ngivuke ngejubane nomuntu engincintisana naye?
Ijubane: 12 km / h
Ibanga: 10 km
I-10 km / 12 km / h = 0.83 h = imizuzu engu-50
Phendula: Kufanele ngiqede inkambo emizuzwini engama-50 ukuze ngisheshise njengomncintiswano wami.
- Qhubeka: Bala ukushesha
