Yintoni ixabiso kumda wesangqa kunye scalar ntoni? Kwathi malunga isakhiwo

amagama ababini yesikolo eloyikekayo - kumda wesangqa kunye scalar - bona okunene eyoyikekayo. Ukuba ufika kwisifundo ngomdla, bonke ukuqonda. Eli nqaku liza kujonga yintoni ixabiso kumda wesangqa, yaye ezinye scalar. Okunye ncam, imizekelo ngoku. umfundi ngamnye kufuneka ukuba ihlawulwe ingqalelo, ukuba physics, ezinye amaxabiso ziphawulwe uphawu nje kuphela, kodwa utolo ukusuka phezulu. Athetha ntoni? Oku kuza kuxoxwa ngezantsi. Sizama ukuqonda umahluko phakathi wobungakanani kumda wesangqa ye scalar.

Imizekelo zithwala. Ezithe zafunyaniswa

Lithetha ukuthini kumda wesangqa? Yini ephawula intshukumo. Akukhathaliseki, emajukujukwini okanye ngenqwelo-moya. Yintoni na ixabiso kumda wesangqa konke konke? Umzekelo, inqwelo-moya uhamba kwi ngesantya ethile ukuphakama, uzelwe enobunzima ethile, ndaqalisa ukuhamba ngaphandle moya kunye kukukhawuleziswa kuyimfuneko. Oko ibhekisa intshukumo-moya? Yintoni eyabangela ukuba ukubhabha? Kakade ke, isantya umcephe. Vector zisebenzisa ikhosi physics i xikombiso lexinene. Makayixhome ungaguquki, nasebulawini yomzobo enxulumene intshukumo, intshukumo.

Amanzi, kakhulu, nibuse kwi ngesantya elithile ukusuka phezulu entabeni. Uyabona? I intshukumo eyenziweyo ngenxa akukho umthamo okanye ubunzima, oko kukuthi isantya. Tennis yenza kube lula ukuhambisa ibhola usebenzisa emsindweni. Oku kucwangcisa kukukhawuleziswa. Hi ndlela leyi, kulo mzekelo, awona mandla awasebenzisayo naye ubungakanani yomzobo yesiboniso. Ngenxa enokuba kubhaliwe ifunyenwe ngenxa ngezantya acwangciswe ngaphambili kunye accelerations. Power anokwahluka, benze izinto ezithile. The Wind Oko Shakes amahlamvu emithini, kakhulu, kungathathwa umzekelo. Ekubeni kukho isantya.

amanani akhabayo kunye navumelanayo

A ubungakanani kumda wesangqa nasebulawini into kulwalathiso kwisithuba olungqonge kunye umnqongo. Kwakhona kukho igama eloyikekayo, eli xesha yunithi. Masithi ufuna ukusombulula puzzle, nto leyo iza yi engenaxabiso yokunyusa. Kwindalo, amaxabiso akhabanayo, ibiya kubonakala, ayikho. Njengoko isantya ingaba mibi?

In kumda wesangqa into enjalo. Oku kusebenza, umzekelo, imikhosi ukuba ziyasetyenziswa umzimba, kodwa abe iindlela ezahlukeneyo. Khumbula sesithathu umthetho Newton, apho isenzo ilingana counteraction. Le guys kume intambo. Elinye iqela e shirts blue, le yesibini - in yellow. Le yokugqibela zinamandla. Masithi kumda wesangqa ye amandla sibhekiswe kakuhle. Kwangaxeshanye, okokuqala akunakwenzeka ukutsala intambo, kodwa zama. Kukho amandla ephikisayo.

Vector okanye ubungakanani scalar?

Makhe sithethe umahluko phakathi ubungakanani kumda wesangqa ye scalar. Yintoni parameter alenzi nayiphi na icala, kodwa intsingiselo eyahlukileyo? Nazi ezinye amaxabiso scalar ngezantsi:

• ixesha (okwesibini, umzuzu, imini, ngonyaka);
• ubunzima (gram, ikhilogramu, ton);
• Ubude umgama (sentimitha imitha ngekhilomitha);
• indawo kunye nomthamo (imitha cubic kunye square);
• Lobushushu (degrees Celsius, Fahrenheit);
• umthamo radiation, imitha (bar, X-ray);
• ingxolo, ukungcangcazela (decibels).

Ingaba unayo yonke indlela? No. Yintoni ixabiso kumda wesangqa kunye scalar leyo ukubonisa imizekelo kuphela abonakalisiweyo. Physics, kukho imiba nje kuphela "ubucukubhede, izikhombisi yeefom", ngokunjalo kwicandelo "Umbane kunye Ubutsalane". amandla Lorentz, induction, Imagnethi yomhlaba - konke oku njengoko amanani kumda wesangqa.

Vector kunye scalar kwi fomula

Kwiincwadi physics ifomula rhoqo apho kukho i utolo oluphezulu ngaphezulu. Khumbula umthetho wesibini Newton. Ukomelela ( "F" ngotolo ngasentla) lilingana ubunzima imveliso ( "m") kunye lunikezelo ( "a" ngotolo ngaphezulu). Njengoko kukhankanyiwe ngasentla, amandla kunye lunikezelo na izixa kumda wesangqa, kodwa ubunzima - scalar.

Ngelishwa, asiyiyo yonke zezincwadi ukonyulwa kwezi ezahlukeneyo. Mhlawumbi, oku kwenziwa kube lula ukuba abafundi bengakuthandi ezilahlekisayo. Kungcono ukuthenga iincwadi kunye iimbekiselo, leyo bagxumeka zithwala kwi fomyula.

Ngoko yintoni na ixabiso kumda wesangqa iya kubonisa mzekeliso. Kuyanconywa ukuba anikele ingqalelo imifanekiso kunye nemizobo kwiiklasi physics. izixa Vector abe. Apho ke wayalela umkhosi womxhuzulane? Kakade ke, wehla. Ngenxa yoko, utolo siboniswe kwicala elinye.

Iikholeji zobugcisa bafunda physics ngokunzulu. Kwizinto ezininzi ootitshala uthethe amaxabiso scalar kunye kumda wesangqa. ulwazi olunjalo kufuneka kwimiba: ulwakhiwo, ezothutho, inzululwazi.
