Umxholo
Inkqubo ye-Ukuhamba ngokufana kwe-rectilinear (MRU) Yintshukumo eyenziwa kumgca othe tye, ngesantya esingaguquguqukiyo (ngobukhulu obuqhubekayo kunye nolwalathiso).
Indlela ibizwa ngokuba yindlela echazwa yinto xa usuka kwenye indawo usiya kwenye. IFizikiki ihlela iintshukumo ngokwendlela yazo:
Uluhlu oluqhelekileyo. Yenziwa kwicala elinye kuphela.
- Iyunifomu. Isantya sihlala sihleli, ukukhawulezisa kwayo zero.
- Ukukhawulezisa. Ukukhawulezisa okungapheliyo, oko kukuthi isantya sonyuka okanye sincipha ngendlela engagungqiyo.
Igobile.
- Pendular. Yintshukumo ye-oscillatory, efana naleyo ye-pendulum.
- ISETYHULA. Nge-axis yokujikeleza kunye neradiyo engapheliyo. Indlela yokuhamba ichaza umjikelo.
- Umzekeliso. Indlela yento itsala parabola.
Ukuba intshukumo iyafana kuthetha ukuba isantya sayo sihlala sihleli, isantya asitshintshi. Ukukhawulezisa zero.
Isantya bubungakanani obuchazwa njengomgama ohanjiweyo kwiyunithi yexesha. Umzekelo: iikhilomitha ezingama-40 ngeyure zithetha ukuba ukuhambahamba kuhamba iikhilomitha ezingama-40 ngeyure (40 km / h).
Ukubala umgama ohanjiweyo yinto enesindululo se-rectilinear, ezi datha zilandelayo ziyasetyenziswa: isantya kunye nexesha.
Ukuba uyawazi umgama kunye nesantya kodwa ufuna ukubala ixesha eliza kuthatha, hlula umgama ngesantya:
d / v = tI-50 km / 100 km / h = 1/2 h (0.5 h)
Unokufumana kwakhona isantya ukuba unedatha yomgama kunye nexesha:
D / t = V50 km / = h = 100 km / h
Ngamanye amagama, iimpawu zentshukumo efanayo ye-rectilinear motion (MRU) zezi:
- Indlela ethe tye
- Isantya esiqhubekayo (iyunifomu)
- Ukukhawulezisa iZero
- Ulwalathiso rhoqo
- Jonga kwakhona: Ukuwa simahla kunye nokuphoswa nkqo
Imizekelo yentshukumo efanayo yokuhamba kwakhona
- Uloliwe ushiya iParis ngo-6 kusasa aze afike eLyon ngo-8 ekuseni. Indlela yayo ikumgca othe tye. Umgama phakathi kweGare de Paris kunye neGare de Lyon yi-400 km. Uloliwe uhlala ehamba ngesantya esifanayo, ngaphandle kokukhawulezisa okanye ukubamba iziqhoboshi de ufike kwindawo aya kuyo. Ingaba ukhawuleza kangakanani uloliwe?
Umgama: 400 km
Imozulu: 8 iiyure - 6 iiyure = 2 iiyure
400 km / 2 hrs = 200 km / h
Phendulauloliwe uhamba ngeekhilomitha ezingama-200 ngeyure.
- Indlela esuka endlwini yam ukuya kwitshomi yam iqonde. Nanini na xa ndiyindwendwela, ndiqhuba imoto yam ngesantya seekhilomitha ezingama-20 ngeyure, ndingakhawulezisi okanye ndicothise de ndiye kufika apho. Kundithatha isiqingatha seyure ukufika apho.
Ikude kangakanani indlu yomhlobo wam?
Isantya: 20 km / h
Imozulu: 1/2 h
I-20 km / h / 1/2 h = 10 km
Phendula: indlu yomhlobo wam ikude ngeekhilomitha ezilishumi.
- UJuan uhambisa amaphephandaba kwindawo ahlala kuyo. Njengoko ezazi ngentloko iidilesi, ukhwela ibhayisekile yakhe kwaye wenza indlela yakhe ngaphandle kokuma xa efika kwindlu nganye, endaweni yoko ulahla amaphephandaba kwibhayisikile. Indlela kaJuan ihamba kwisitrato esinye, esithe nkqo, se-2 km. Ihamba ngesantya seekhilomitha ezili-10 ngeyure. UJuan kufuneka aqale ukhenketho emva koko abuyele kwisitalato esinye ngesantya esifanayo. Ukuba uJuan uhamba ngoku, kuya kuthatha ixesha elingakanani ukubuyela?
Kule meko kukho iindlela ezimbini ezifanayo zentshukumo: enye iyahamba kwaye enye ibuye umva.
Isantya: 10 km / h
Umgama: 2 km
2 km / 10 km / h = 0.2 h = 12 imizuzu
Oku kubalwa kuphela kukhenketho olunye.
Imizuzu eli-12 x 2 (uhambo olujikelezayo) = imizuzu engama-24
Phendula: UJuan uzakuthatha imizuzu engama-24 ukubuya.
- Ntsasa nganye ndibaleka iikhilomitha ezilishumi ngqo elunxwemeni, kwaye kuyandithatha iyure enye. Ndifuna ukuphucula isantya sam sokudlala nxamnye nomntu endiza kukhuphisana naye, onokubaleka kwiikhilomitha ezili-12 ngeyure. Kuthatha ixesha elingakanani ukuba ndenze ukukhwela kwam kwesiqhelo ukuze ndiphakamise isantya kunye nomntu endikhuphisana naye?
Isantya: 12 km / h
Umgama: 10 km
I-10 km / 12 km / h = 0.83 h = imizuzu engama-50
Phendula: Kuya kufuneka ndigqibe ikhosi kwimizuzu engama-50 ukuze ndikhawuleze okhuphisana nam.
- Qhubeka kunye: Bala ukukhawulezisa
