Amandla akhoyo kwindawo esingqongileyo kwaye ahlala kuyo yonke indawo yemihla ngemihla kunye nemisebenzi, njengokubaleka, ukuhamba, ukuchola ifowuni ephathwayo okanye ukukhwela ibhayisekile. Iququzelela iinguqu kwindalo yomzimba. Amandla luphawu olunokuthi lugqithiselwe, luthuthwe kwaye lugcinwe. Ngaphezu koko, ixhomekeke kuguqulo ukusuka kwifomu enye ukuya kwenye kwaye inokugcinwa ngokobuninzi, nangona inxalenye ethile ilahleka ngokuguquguqukayo.
Kule nqaku siza kukuxelela yintoni amandla kinetic kwaye siza kukunika imizekelo ukuze iqondwe lula.
Yintoni amandla e-kinetic kwaye aveliswa njani?
Amandla eKinetic abhekisa kumandla omzimba onawo ngenxa yentshukumo yawo. Olu hlobo lwamandla luxhomekeke kubunzima bomzimba kunye nesantya sawo. Imele amandla omsebenzi ovumela into ukuba ihambe ukusuka kwindawo yokuphumla ukuya kwimeko yokunyakaza kwisantya esithile.
Amandla e-Kinetic avela kwintshukumo ngokwayo kwaye inokumiselwa ngokusebenzisa ifomula yamandla e-kinetic: Amandla e-kinetic alingana nesiqingatha semveliso yobunzima (m) amaxesha isikwere sesantya (v). Kwifomu eyenziwe lula, oku kubonakaliswa ngolu hlobo: Ec = ½ * mv².
Ngokomzekelo, umzimba ohlala ekuphumleni okupheleleyo une-coefficient yamandla e-kinetic ye-0. Xa iqala ukuhamba kunye namava okukhawuleza, amandla e-kinetic omzimba aya kwanda. Nangona kunjalo, ukuze umzimba ubuyele kwimeko yokuphumla, kufuneka uthabathe inani lamandla alinganayo, kodwa ngendlela engafanelekanga, kuloo nto ifunyenwe ekuqaleni ukuqala ukuhamba kwayo.
Ukuguqulwa kwamandla e-kinetic abe ngamandla ombane
Ukuguqulwa kwamandla e-kinetic abe ngamandla ombane kwenzeka ngesixhobo esaziwa ngokuba yijenereyitha yombane. Kulo mxholo, amandla omatshini, ngokukodwa amandla e-kinetic, aguqulwa abe ngumbane. Umthombo wamandla wokuqala unokuvela kwizinto ezahlukeneyo zendalo, ezifana namanzi okanye umoya, ovelisa intshukumo ethi emva koko ivumele ijenereyitha ukuba ivelise umbane.
Amandla eKinetic asebenza njengendlela yokuvelisa umbane okanye ubushushu. Umzekelo wokuguqulwa kwamandla e-kinetic kumandla ombane ufumaneka kwi-dynamo yebhayisikili: ukujikeleza kwevili kubangela ukuba i-dynamo ijikeleze, ngaloo ndlela isebenze ukukhanya kwebhayisikili. Kwinkalo yamandla ahlaziyekayo, omnye umzekelo ngamandla ombane aveliswa ziindlela ezisetyenziswa kumandla omoya. Le nkqubo ngokusisiseko iguqula amandla ekinetic abe ngamandla ombane ngokushukuma kwamaphiko abekwe kwiiinjini zomoya.
Amandla eKinetic ngokwenkalo yokufunda
Amandla eKinetic aneempawu ezixhomekeke kwicandelo lokufunda:
- Kulo oomatshini beklasikhi, amandla ekinetic omzimba amiselwa bubunzima nesantya sawo, esiya kuthi ngokungaguquguqukiyo sibe ngaphantsi kakhulu kunesantya sokukhanya.
- Kwintsimi ye iindlela zokulungisa izinto, isenzeko apho isantya sento (v) sisondela kweso sokukhanya, esimelwa kwifiziksi ngesimboli c, sifundwa. Kwiimeko ezinjalo, i-equation yamandla e-kinetic iyahluka kuleyo ye-classical mechanics, ngakumbi kuba la mandla axhomekeke kubudlelwane phakathi kwe-v kunye no-c.
- Kwintsimi ye i-quantum mechanics, iziganeko ezinxulumene ne-subatomic particles, kuquka i-electron, zichazwe. Le ithiyori ibonisa inqanaba elibalulekileyo lokuntsonkotha, apho ubungakanani bomzimba, njengamandla ekinetic, bubonakaliswa yimisebenzi yamaza ebonisa okunokwenzeka.
Imizekelo yamandla ekinetic
Makhe sinike imizekelo yamandla e-kinetic ukuze kucace ukuba yintoni na:
- Xa umntu eseta isithuthuthu sishukume, amandla e-kinetic aveliswa ngoko nangoko njengoko i-scooter iqala ukuhamba. Kwimeko ye-vase yeglasi ekuwa kwamahhala, amandla okuxhuzula asebenzisa impembelelo kwi-vase, okukhokelela ekuqokeleleni kwamandla e-kinetic njengoko ehla. La mandla akhululwa ekugqibeleni xa echaphazeleka emhlabeni okanye komnye umphezulu, nto leyo ebangela ukuba ivazi iqhekeke.
- Xa ibhola ijulwe, ukusebenzisa amandla kwibhola emileyo kuvelisa ukukhawuleza kwayo, okubangela ukuba igubungele umgama othile ohambelana nobukhulu bamandla asetyenziswayo. Ngexesha lokuhamba kwayo, ibhola ivelisa amandla e-kinetic.
- Ilitye elihamba lisihla kwithambeka lenza amandla ekinetic, exhomekeke kokubini kubunzima belitye kunye nesantya esifikelela kuso ngexesha lokuhla. Ngokufanayo, isenzo sokuhamba siphinda sivelise amandla e-kinetic, kunye neenguqu ezithintekayo kubunzima bomntu kunye nesantya apho ukunyakaza kwenzeka khona. Umzekelo, ukuba umntu ebenokubaleka endaweni yokuhamba, ubungakanani bamandla avelisiweyo bebuya kwanda kakhulu.
- Isithuthi se-roller coaster. Kwipaki yokuzonwabisa, isithuthi se-roller coaster sinamandla anokubakho de kube ngumzuzu oqala ngawo ukuhla, apho isantya kunye nobunzima bayo bunegalelo ekwandiseni amandla e-kinetic. La mandla e-kinetic aya kuba mkhulu xa isithuthi sihlala kunokuba singenanto, njengoko ubunzima buya kuba bukhulu kakhulu.
- Ukubetha umntu emhlabeni kubandakanya ukudluliselwa okuthe ngqo kwamandla e-kinetic. Xa sibalekela kumhlobo kwaye sitsibe phezu kwakhe, amandla ekinetic aqokelelwe ngexesha lokubaleka aya kudlula lawo akwindawo emileyo. Umzimba uya kunqoba inertia yawo, ebangela ukuba umhlobo awe phantsi. Phezu kwempembelelo, yomibini imizimba iya kudibanisa amandla e-kinetic kwaye ekugqibeleni iyeke xa ifika emhlabeni.
Umahluko phakathi kwekinetic kunye namandla anokubakho
Amandla azibonakalisa ngeendlela ezahlukeneyo, kubandakanya i-thermal, inyukliya, i-electromagnetic, kunye noomatshini, phakathi kwabanye. Amandla eKinetic, njengoko sele sikhankanyile ngasentla, abhekisa kumandla ento enayo ngenxa yentshukumo yayo. Okuphikisanayo, Amandla anokwenzeka achazwa njengamandla ekuthi into inawo ngenxa yendawo ekuyo; Umzekelo, into ebekwe kumphakamo inamandla amakhulu anokubakho xa kuthelekiswa naleyo ibekwe kumgangatho ophantsi, ebonisa amandla enawo kwindawo yokugcina.
Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga namandla e-kinetic kunye neminye imizekelo.
