Kumanqaku angaphambili sihlalutye ngokucokisekileyo amandla e-kinetic nayo yonke into enxulumene nayo. Kule meko, siyaqhubeka noqeqesho kwaye siyaqhubeka nokufunda amandla oomatshini. Olu hlobo lwamandla luveliswa ngumsebenzi womzimba. Inokudluliselwa phakathi kweminye imizimba. Kunokuthiwa sisixa samandla e-kinetic aveliswa kukuhamba kwemizimba, kunye nelastiki kunye / okanye amandla omxhuzulane anokubakho. La mandla aveliswa kukudibana kwemizimba ngokunxulumene nendawo umntu ngamnye anayo.
Kule posi uya kufunda yonke into enxulumene namandla oomatshini, kwindlela esebenza ngayo nendlela yokuyibala kunye nezixhobo zayo. Ngaba ungathanda ukufunda ngako? Qhubeka ufunde 🙂
Ingcaciso yamandla oomatshini
Ukwenza kube lula ukuyiqonda, masenze umzekelo. Makhe sicinge ngento ephoswa kude kude nomhlaba. Into leyo iya kuthwala amandla e-kinetic angaphambili kuba iyahamba. Njengoko iqhubela phambili, ifumana isantya kunye namandla omxhuzulane xa iphakanyisiwe ngaphezulu komgangatho womhlaba. Masithathe umzekelo wokuphoswa kwebhola.
Ukuthatha ingqalelo yokuba ingalo yethu iwenza umsebenzi kwibhola, iyayidlulisela kuyo amandla e-kinetic ukuze ikwazi ukuhamba. Kulo mzekelo siza kuqwalasela amandla okungqubana okukhoyo nomoya Okanye kungenza ukubala kunye nokufunda umxholo kube nzima kakhulu. Xa ibhola iphoswe kwaye isemoyeni, ithwala amandla e-kinetic ayiqhubayo ukuze ihambise kunye namandla amandla omxhuzulane ayitsalela emhlabeni kuba iphakanyisiwe.
Kufuneka sihlale sikhumbula ukuba siphantsi kwamandla omxhuzulane. Umxhuzulane womhlaba usityhalela emhlabeni ukukhawuleziswa kweemitha ezili-9,8 ngesikweri ngasinye. Yomibini le mikhosi inxibelelana nebhola inejubane elahlukileyo, ukukhawulezisa kunye nolwalathiso. Ke ngoko, amandla oomatshini sisiphumo samandla omabini.
Iyunithi yokulinganisa kwamandla oomatshini, ngokweNkqubo yeHlabathi, yijoule.
Ifomula
Kwifiziksi, ukubala amandla oomatshini kuguqulela kwisibalo samandla e-kinetic kunye namandla anokubakho. Oku kuchazwa yifomula:
Em = U-Ec + Ep
Apho u-Em amandla oomatshini, i-Ec i-kinetic kunye ne-Ep enokubakho. Sibonile ifomula yamandla ekinetic kwenye iposti. Xa sithetha ngamandla anokubakho omxhuzulane, sithetha ngesiphumo sobunzima bamaxesha obunzima kunye nomxhuzulane. Ukuphindaphindwa kwezi yunithi kusibonisa amandla anokubakho ento.
Umgaqo wolondolozo lwamandla
Ootitshala bahlala begxininisa kaninzi ukuba amandla awenziwanga okanye atshabalalise, kodwa aguqulwe. Oku kusizisa kumgaqo wolondolozo lwamandla.
Xa amandla oomatshini evela kwinkqubo eyodwa (enye apho kungekho kungqubana) isekwe kwimikhosi yokulondoloza (egcina amandla oomatshini enkqubo) Isiphumo sayo siya kuhlala sihleli. Kwenye imeko, amandla omzimba aya kuhlala ehleli nje ukuba utshintsho lwenzeka kuphela kwimowudi yamandla hayi kwixabiso lalo. Oko kukuthi, ukuba amandla atshintshiwe ukusuka kwi-kinetic ukuya kwi-potential or mechanical.
Umzekelo, ukuba siphosa ibhola ngokuthe nkqo iya kuba nayo yonke ikinetic kunye namandla anokubakho ngexesha lokunyuka. Nangona kunjalo, xa ifikelela kwelona nqanaba liphezulu, imisiwe ngaphandle kokufuduswa, iya kuba namandla okomelela kuphela. Kule meko, amandla agciniwe, kodwa kwimowudi enokubakho.
Oku kuncitshiswa kunokubonakaliswa ngemathematics kunye ne-equation:
Em = Ec + Ep = rhoqo
Imizekelo yokuzivocavoca
Ukubonelela ngemfundiso engcono yolu hlobo lwamandla, siza kubeka imizekelo embalwa yokuzivocavoca kwaye siza kuyisombulula inyathelo ngenyathelo. Kule mibuzo siza kubandakanya iintlobo ezahlukeneyo zamandla esele sizibonile ukuza kuthi ga ngoku.
- Jonga ukhetho olungalunganga:
- a) Amandla eKinetic ngamandla anawo umzimba, kuba ayashukuma.
- b) Kunokuthiwa amandla emxhuzulane amandla anawo umzimba kuba ubekwe kwindawo ethile ephezulu ngaphezulu komhlaba.
- c) Amandla oomatshini apheleleyo emzimbeni aqhelekile, nokuba kubonakala ukubambana.
- d) Amandla apheleleyo kwindalo iphela ahlala ehleli, kwaye anokuguqulwa ukusuka kwifom enye ukuya kwenye; nangona kunjalo, ayinakwenziwa okanye itshatyalaliswe.
- e) Xa umzimba unamandla e-kinetic, uyakwazi ukwenza umsebenzi.
Kule meko, ukhetho olungalunganga lolokugqibela. Umsebenzi awenziwa yinto ene-kinetic energyKodwa umzimba okunike loo mandla. Masibuyele kumzekelo webhola. Ngokuyiphosa emoyeni, sithi abenza umsebenzi ukuyinika amandla e-kinetic ukuba ahambe.
- Masithi ibhasi enobunzima be-m ihamba kwindlela yentaba kwaye yehle ngobude h. Umqhubi webhasi ugcina iziqhoboshi ukuphepha ukuphazamiseka ekwehleni. Oku kugcina isantya sebhasi rhoqo naxa ibhasi isihla. Ukujonga le miba, bonisa ukuba iyinyani okanye ayiyonyani:
- Ukwahluka kwamandla e-kinetic emoto zero.
- Amandla ombane wenkqubo ye-bus-Earth alondoloziwe, kuba isantya sebhasi sihlala sihleli.
- Amandla ewonke ebhasi-yenkqubo yoMhlaba alondoloziwe, nangona inxenye yamandla oomatshini iguqulwe yangamandla angaphakathi.
Impendulo yalo msebenzi ngu-V, F, V. Oko kukuthi, ukhetho lokuqala luyinyani. Ukuba siya kwifomula yamandla e-kinetic sinokubona ukuba isantya sihlala sihleli, amandla e-kinetic ahlala ehleli. Amandla oomatshini akalondolozwanga, kuba amandla emxhuzulane aqhubeka ngokwahluka xa ehla evela kwiindawo eziphakamileyo. Eyokugqibela iyinyani, kuba amandla engaphakathi esithuthi akhula ukugcina umzimba uhamba.
Ndiyathemba ukuba ngale mizekelo ungafunda ngcono malunga namandla oomatshini kwaye upase iimviwo zomzimba ezixabisa kakhulu kubantu abaninzi
