Amandla eKinetic: iintlobo, inkcazo, ifomula kunye nemizekelo

Ngokuqinisekileyo ufunde kwiziko amandla e-kinetic kwisifundo se-physics. Ukuba akunjalo, mhlawumbi uvile ngayo kwisayensi okanye kwimidiya. Kwaye kuthathwa njengamandla abaluleke kakhulu kufundisiso lokuhamba kwezinto. Kukho abantu abangacacanga kakuhle kwimbono yamandla ekinetic okanye ukuba ilinganiswa okanye isebenza njani. Kule nqaku siza kuphinda sihlolisise inkcazo kunye nezixhobo ezinamandla kweli hlabathi le-physics.

Ngaba uyafuna ukwazi yonke into enxulumene namandla e-kinetic? Kufuneka uqhubeke ufunda ukuze ufunde yonke into 🙂

Iyintoni inkcazo yamandla ekinetic?

Xa uthetha ngolu hlobo lwamandla, kucingelwa ukuba amandla afunyenwe ukwenza umbane okanye into enjalo. Amandla eKinetic ngamandla anayo into ngenxa yokuba ihamba. Xa sifuna ukukhawulezisa into, kufuneka sisebenzise amandla athile kuyo ukuze yoyise amandla okruthana komhlaba okanye omoya. Ukwenza oku, ngenxa yoku, sihambisa amandla kwinto kwaye iya kuba nakho ukuhamba ngesantya esingaguquguqukiyo.

Nguwo amandla agqityiweyo abizwa ngokuba yi-kinetic energy. Ukuba amandla asetyenzisiweyo kwinto ayanda, into iya kukhawulezisa. Nangona kunjalo, ukuba siyayeka ukusebenzisa amandla kuyo, ngamandla okhukula amandla ayo e-kinetic aya kuncipha ade ayeke. Amandla eKinetic axhomekeke kubunzima nakwisantya efikelela kwinto. Amalungu anobunzima obuncinci afuna umsebenzi omncinci ukuqala ukuhamba. Ngokukhawuleza uya, amandla okhenkethi angaphezulu komzimba wakho.

Amandla zinokudluliselwa kwizinto ezahlukeneyo kwaye phakathi kwabo batshintshe babe lolunye uhlobo lwamandla. Umzekelo, ukuba umntu ubaleka aze adibane nomnye owayephumle, inxenye yamandla e-kinetic awayekwiimbaleki iya kudluliselwa komnye umntu. Amandla ekufuneka esetyenziselwe intshukumo ukuze ibekhona kufuneka abe mkhulu kunamandla okuxubana emhlabeni okanye olunye ulwelo njengamanzi okanye umoya.

Iindidi zamandla eKinetic

Zimbini iintlobo ezahlukileyo:

Amandla aguquguqukayo ekinetic: kwenzeka ntoni xa into ichaza umgca othe ngqo.
Amandla e-Rotary kinetic: yile yenzekayo xa into ijika kuye.

Ubala njani amandla e-kinetic?

Ukuba sifuna ukubala ixabiso la mandla, kuya kufuneka silandele ukuqiqa okuchazwe ngasentla. Okokuqala, siqala ngokufumana umsebenzi owenziweyo. Umsebenzi kufuneka wenziwe ukuhambisa amandla e-kinetic ukuya kwinto. Kwakhona, loo msebenzi kufuneka uphindwe ngamandla, kuthathelwa ingqalelo ubunzima bezinto ezityhalelweyo umgama. Umkhosi kufuneka uhambelane nomphezulu apho ukho, kungenjalo into ayinakushukuma.

Khawufane ucinge ukuba ufuna ukuhambisa ibhokisi, kodwa uyatyhala uye emhlabeni. Ibhokisi ayinakukwazi ukoyisa ukuxhathisa komhlaba kwaye ayizukuhamba. Ukuhamba, kufuneka sisebenzise umsebenzi kwaye sinyanzele kwicala elilinganayo nomphezulu.

Siza kubiza emsebenzini W, amandla F, ubunzima bento m, kunye nomgama d.

Umsebenzi ulingana namaxesha okunyanzelwa komgama. Oko kukuthi, umsebenzi owenziweyo ulingana namandla asetyenziswa kwinto leyo kunye nomgama ohamba kuwo ubulela kuloo mandla asetyenzisiweyo. Inkcazo yamandla inikwa ngobunzima kunye nokukhawulezisa kwento. Ukuba into ihamba ngesantya esingaguqukiyo, oko kuthetha ukuba amandla asetyenziswayo kunye nomlo wokungqubana unexabiso elifanayo. Ke ngoko, yimikhosi egcinwa ibhalansi.

Amandla okulwa kunye nokukhawulezisa

Ngokukhawuleza ukuba ixabiso lamandla asetyenziswa kwinto liyehla, liya kuqala ukuthoba isantya de liyeke. Umzekelo olula kakhulu yimoto. Xa siqhuba kuhola wendlela, i-asphalt, ukungcola, njl. Lowo siqhuba ngaye usinika ukuxhathisa. Olu xhathiso Yaziwa njengamandla okuxubana phakathi kwevili kunye nomphezulu. Ukuze imoto inyuse isantya sayo, kufuneka sitshise ipetroli ukuze sivelise amandla e-kinetic. Ngala mandla ungoyisa ukungqubana kwaye uqale ukuhamba.

Nangona kunjalo, ukuba sihamba nemoto kwaye siyeke ukukhawulezisa, siya kuyeka ukusebenzisa amandla. Ngaphandle kwawo nawuphi na amandla emotweni, amandla okuxubana awayi kuqala ukuphuka de isithuthi siyeke. Ngesi sizathu, kubalulekile ukuba uyazi kakuhle imikhosi engenelela kwinkqubo yokwazi ukuba yeyiphi na into eza kuyithatha.

Ifomula yamandla eKinetic

Ukubala amandla e-kinetic kukho i-equation evela kwingqiqo esetyenziswe ngaphambili. Ukuba siyayazi isantya sokuqala kunye nesokugqibela sento emva komgama ohanjiweyo, sinokufaka endaweni yokukhawulezisa kwifom.

Ke ngoko, xa isixa semali somsebenzi senziwe kwinto, isixa esisibiza ngokuba ngamandla ekinetic utshintsho.

Yintoni enomdla ngayo?

Kwifiziksi, ukwazi amandla e-kinetic wento kubalulekile ekufundeni amandla ayo. Kukho izinto zesibhakabhaka esine-kinetic energy eqhutywa yi-Big Bang ethi, kude kube namhla, isasebenza. Kuyo yonke inkqubo yeLanga kukho izinto ezinomdla zokufundwa kwaye kuyimfuneko ukwazi amandla abo e-kinetic ukuqikelela umkhondo wabo.

Xa sihlalutya i-equation yamandla e-kinetic kunokubonakala ukuba ixhomekeke kwisantya sento ephindwe kabini. Oku kuthetha ukuba xa isantya siphindwe kabini, i-kinetics yayo iphindaphindwe kane. Ukuba imoto ihamba nge-100km / h unamandla aphindwe kane ngaphezu kohamba nge-50km / h. Ke ngoko, umonakalo onokuthi ufumaneke kwingozi uphindaphindwe kane komelele kunomnye.

La mandla akanakuba lixabiso elibi. Ihlala ihleli ingu-zero okanye i-positive. Ngokungafaniyo nayo, isantya sinokuba nexabiso elifanelekileyo okanye elibi ngokuxhomekeka kwisalathiso. Kodwa xa usebenzisa isantya esiphindwe kabini, uhlala ufumana ixabiso elifanelekileyo.

Imizekelo yamandla ekinetic

Makhe sibone imizekelo yamandla ekinetic ukuyenza icace:

Xa sibona umntu kwisikuta sibona ukuba banamava ukonyuka kokubini kwamandla anokubakho xa usiya kubude nakumandla e-kinetic ngesantya esandayo. Umntu onobunzima obukhulu bomzimba uya kuba nakho ukufumana amandla amakhulu e-kinetic okoko nje isithuthuthu simvumela ukuba ahambe ngokukhawuleza.
Ingqayi ye-porcelain ewela emhlabeni: Olu hlobo lomzekelo lubalulekile ekuqondeni amandla e-kinetic. Amandla ayakha emzimbeni wakho njengoko usihla kwaye ukhutshwa ngokupheleleyo xa uqhekeka ungangeni emhlabeni. Sisibetho sokuqala esiqala ukuvelisa amandla e-kinetic. Amanye amandla e-kinetic afunyenwe ngumxhuzulane woMhlaba.
Ukubetha kwibhola: yimeko efanayo naleyo yenzekayo ngevasi. Ibhola ekuphumleni lifumana ukulingana kwaye amandla e-kinetic aqala ukukhutshwa xa siyibetha. Inzima kwaye inkulu ibhola, kokukhona kuya kuthatha umsebenzi ukumisa okanye ukuyihambisa.
Xa siphosa ilitye ezantsi kwithambeka: kwenzeka ngendlela efanayo nevazi kunye nebhola. Njengokuba iliwa lisihla kwithambeka, amandla alo e-kinetic ayenyuka. Amandla aya kuxhomekeka kubunzima kunye nesantya sokuwa kwawo. Oku kuya kuthi kuxhomekeke kwithambeka.
Imoto eqengqelekayoIipaki zokuzonwabisa zingundoqo ekuchazeni amandla e-kinetic. Kwi-roller coaster, imoto ifumana amandla e-kinetic njengoko iwe kwaye inyusa isantya sayo.

Ndiyathemba ukuba ngolu lwazi umxholo kunye nokusetyenziswa kwawo kuya kucaca ngakumbi kuwe.
