La Amandla eKinetic ngamandla anxulumene nentshukumo kunye amandla anokubakho ngamandla anxulumene nesikhundla kwinkqubo. Xa sithetha ngokubanzi, amandla amele amandla ento okanye inkqubo yokwenza umsebenzi. Kukho iindidi ezimbini zamandla asisiseko: kinetic kunye nenokwenzeka. Naluphi na olunye uhlobo lwamandla lusuka kwezi zimbini, okanye ludityaniswe zombini. Umzekelo, i amandla oomatshini Sisimbuku samandla ekinetic kunye namandla anokubakho enkqubo.
Kweli nqaku siza kuhlolisisa yonke into oyifunayo ukuze ukwazi malunga namandla e-kinetic kunye namandla anokubakho, indlela abasebenza ngayo, iimpawu zabo, imizekelo kunye neentlobo. Ukongeza, uya kufunda ukuba ezi ntlobo zimbini zamandla zisebenzisana njani kwaye ziguqule omnye komnye phantsi kweemeko ezahlukeneyo.
Kinetic kunye namandla anokubakho
Amandla eKinetic
Amandla eKinetic ngamandla ahambelana nokushukuma kwezinto. Nantoni na ehambayo inamandla e-kinetic, kwaye ubungakanani boku buxhomekeke kwizinto ezimbini eziphambili: ubunzima bento kunye nesantya sayo. Okukhona ubunzima bukhulu okanye isantya sikhulu, kokukhona siphezulu amandla ekinetic.
Kwi-International System (SI), amandla e-kinetic alinganiswa iijuwuli (J). Ngokwezibalo, ifomula yokubala yile:
Ec = 1/2 m * v^2,
phi:
- m bubunzima bento ngeekhilogram (kg).
- v sisantya sento kwiimitha ngomzuzwana (m/s).
Oko kukuthi, i Amandla eKinetic alingana nobunzima bento kunye nesikwere sesantya sayo. Oku kuthetha ukuba ukunyuka kwesantya kunempembelelo enkulu kumandla e-kinetic kunokunyuka kobunzima.
Imizekelo yamandla ekinetic
- Ukubhowula: Xa umntu ephosa ibhola, ifumana amandla e-kinetic. Ubungakanani bamandla buxhomekeke kwisantya kunye nobunzima bebhola.
- Umoya: Umoya uhamba emoyeni. Amandla ekinetic omoya anokuguqulwa abe ngumbane kusetyenziswa iiinjini zomoya.
- Kushushu: Amandla e-Thermal yindlela encinci yamandla e-kinetic, apho amasuntswana enkqubo ahamba kwinqanaba le-molecular xa eshushu.
Amandla anokubakho
Amandla anokwenzeka, ngokungafaniyo namandla e-kinetic, amandla agcinwe kwinto ngenxa yendawo okanye ubumbeko bayo. La mandla "afihlakele" ade akhululwe ngohlobo oluthile lokusebenzisana njengokuwa, ukolula kwentwasahlobo, okanye ukukhutshwa kombane.
Njengamandla e-kinetic, amandla anokubakho nawo alinganiswa kwiijoules (J). Enye yeendlela eziqhelekileyo zamandla anokubakho amandla omxhuzulane anokubakho, ehambelana nokuphakama kwento kwintsimi yomxhuzulane.
Ifomula yokubala amandla omxhuzulane anokubakho yile:
Ep = mgh,
phi:
- m bubunzima bento ngeekhilogram.
- g kukukhawuleza okubangelwa ngumxhuzulane (9,8 m/s² eMhlabeni).
- h bubude beemitha.
Imizekelo yamandla anokubakho
- Intwasahlobo eyoluliweyo okanye exiniweyo: Intlakohlaza igcina amandla anokunwebeka. Xa intwasahlobo ikhutshwa, amandla anokubakho aguqulwa abe yi-kinetic energy.
- Amadama: Amanzi agcinwe edamini anamandla omxhuzulane. Oku kuguqulwa kumandla e-kinetic xa amanzi esihla kwaye ajikelezisa iiinjini zokuvelisa umbane.
- Guqa kwaye ukhombe: Amandla anamandla e-Elastic agcinwa xa isaphetha sitsalwa. Xa ukhulula umtya, la mandla aguqulwa abe ngamandla e-kinetic aqhubela phambili utolo.
Asebenza njani amandla ekinetic?
Ukuze into ifumane ukunyakaza kwaye, ngoko ke, amandla e-kinetic, kuyimfuneko ukusebenzisa a amandla angaphandle. Okukhona amandla kunye nexesha lisetyenziswa, kokukhona isantya sikhulu, kwaye ngenxa yoko, kokukhona makhulu amandla ayo ekinetic. Ngokunjalo, ukuba ubunzima bomzimba bukhulu, buya kuba namandla amaninzi ekinetic xa kuthelekiswa nomzimba omncinci ohamba ngesantya esifanayo.
Uphawu olubalulekileyo lwamandla e-kinetic kukuba luyakwazi ugqithiselo ukusuka komnye umzimba ukuya komnye. Ngokomzekelo, xa inqwelo-mafutha ehambayo ingqubana nenye inqwelo-mafutha, amanye amandla ayo e<em>kinetic akhutshelwa kweyesibini, nto leyo enokubangela ukuba nayo ihambe.
Iimpawu zamandla e-kinetic
- Kukubonakaliswa kwamandla ahambelana nokunyakaza.
- Iyakwazi ukudluliselwa ukusuka kwenye into ukuya kwenye.
- Unokuguqula ube ezinye iindlela zamandla, ezifana amandla obushushu xa kukho ukungqubana.
- Ubukhulu bayo buxhomekeke kubunzima kunye nesantya sento.
La isixa samandla ekhinetiki kunye namandla anokubakho yenkqubo yinto eyaziwa ngokuba amandla oomatshini. Zombini iintlobo zamandla zinokuguqulwa komnye nomnye, kuxhomekeke kwiimeko zenkqubo.
Iindidi zamandla anokubakho
amandla omxhuzulane anokubakho
La amandla omxhuzulane anokubakho Ngamandla into enayo ngenxa yokuphakama kwayo kwintsimi yomxhuzulane. Okukhona umphakamo wento usiba mkhulu, kokukhona abe mkhulu amandla ayo omxhuzulane.
Umzekelo oqhelekileyo ngulo ka iroller coaster. Xa uloliwe uphezulu, unomthamo omkhulu wamandla anokubakho. Njengoko ihla, la mandla aguqulwa abe ngamandla e-kinetic.
elastiki amandla anokubakho
La elastiki amandla anokubakho Ngamandla agcinwe kwizinto ezinokolulwa okanye zixinzelelwe, ezifana ne-spring okanye i-rubber band. Xa uxinezeleko lukhutshwa, la mandla aguqulwa ngokukhawuleza abe ngamandla ekinetic.
amandla anokubakho kwikhemikhali
La amandla anokubakho kwikhemikhali Igcinwe kwiibhondi zeemolekyuli kunye neeathomu. La mandla akhutshwa ngexesha lokusabela kwemichiza, njengaxa sitshisa amafutha efosili okanye xa umzimba womntu usebenzisa iswekile ukuvelisa amandla.
amandla anokubakho e-electrostatic
Kwintsimi yombane, amandla anokubakho e-electrostatic ngamandla agcinwe kumasuntswana atshajelwe ngumbane ngenxa yendawo yawo kwindawo yombane. La mandla anokuguqulwa abe kwezinye iindidi, ezifana nokukhanya okanye amandla okushisa, njengoko kwenzeka kwiisekethe zombane.
Amandla e-Kinetic kunye namandla anokubakho abalulekile ekuqondeni indlela umhlaba wenyama osebenza ngayo. Kungumbulelo wentsebenziswano phakathi kwezi ntlobo zimbini zamandla esinokuthi sizichaze iziganeko ngokwahlukeneyo njengokubhabha kwenqwelomoya, ukuhamba komlambo okanye nokusebenza kwemoto.
