Muviri wakasimba unoonekwa sewakaumbwa nezvidimbu zvakawanda, uye huremu hwechinhu ihuwandu hwehuwandu hwezvikamu chimwe nechimwe zvinoumba chinhu. Pakati pehukuru ipoindi iri pachinhu apo huremu hwezvikamu zvese zvinoumba chinhu hunoonekwa sehwakabatana panzvimbo iyoyo.

Fomura
Muviri wega wega wakasimba unofungidzirwa kuti unoumbwa nezvidimbu zvakawanda, chimwe nechimwe chazvo chiri kure zvakanyanya kubva kune chimwe. Zvisinei, kuti zvive nyore kuwana fomura yekuona pakati pehukuru, zviri nyore kufungidzira kuti muviri wakasimba une zvidimbu zviviri chete. Zvikamu zviviri izvi zvinogona kunzi sisitimu yemuviri wakasimba.

Kunzwisisa Nzvimbo Yekukwevera Simba
Chinhu chakasimba chinoonekwa sechinoumbwa nezvidimbu zvakawanda nekuda kweizvi simba rinokwevera pasi chinoshanda pane chimwe nechimwe chezvikamu izvi. Nemamwe mashoko, chikamu chimwe nechimwe chine huremu hwacho. Pakati pechinhu chinokwevera pasi ipo pachinhu kana kuti chakakomberedza huremu hwezvikamu zvese zvechinhu chacho.

Kana chinhu chakafanana (huwandu hwezvimwe zvinhu hwakafanana kana kuti chinhu chacho chakagadzirwa nezvinhu zvakafanana) uye chimiro chechinhu chacho chakaenzana (semuenzaniso sikweya, rectangle, denderedzwa) saka pakati pesimba rechinhu chacho panoenderana nepakati pehukuru hwechinhu chiri pakati pechinhu chacho. Kune triangle, pakati pehukuru pacho pa 1/3 awa, apo h = kureba kwetriangle.

Hazvisi zvinhu zvese zvatinosangana nazvo muhupenyu hwezuva nezuva zvinogara zvakazorora. Chinhu chinogona kunge chakazorora pakutanga, asi kana chikafambiswa, chinogona kufamba. Mubvunzo ndewokuti chinodzokera panzvimbo yacho yekutanga here kana kuti kwete mushure mekufamba. Izvi zvinoenderana nekufamba kwacho. mhando dzekuenzanisa kwechinhu izvo.
Kana chinhu chiri pachigaro chikasangana nekukanganisika (kune simba rinobuda kana kuti nguva yesimba rinobuda richishanda pachinhu chacho) chinhu chacho chinozofamba. Mushure mekufamba, pachava nemikana mitatu, inoti: (1) chinhu chinodzokera panzvimbo yacho yekutanga, (2) chinhu chinoenda kubva panzvimbo yacho yekutanga, (3) chinhu chinoramba chiri panzvimbo yacho itsva. Kana mushure mekufamba, chinhu chikadzokera panzvimbo yacho yekutanga, chinhu chacho chinenge chiri mukati. kuenzana kwakasimbaKana mushure mekufamba, chinhu chikafamba kure kubva panzvimbo yacho yekutanga, chinhu chacho chinenge chiri mukati. kuenzana kusina kugadzikanaKune rumwe rutivi, kana mushure mekufambisa chinhu chikaramba chiri panzvimbo yacho itsva, chinhu chacho chinenge chiri kuenzana kwakasununguka.

Mienzaniso mishanu yemibvunzo yebasa refizikisi uye kinetic energy

1. Mota ine huremu hwe5000 kg inotanga yakamira, yozofamba nekumhanya kwe20 m/s. Sarudza basa rose rakaitwa pamota...
Kukurukurirana
Zvinozivikanwa :
Huremu (m) = 5000 kg
Kumhanya kwekutanga (v)_o) = 0 m/s (pakutanga mota inenge yakamira)
Kumhanya kwekupedzisira (v)_t) = 20 m/s

Mienzaniso gumi nemishanu yeMibvunzo yeNheyo dzeBlack

1. Aizi ine huremu hwe 0,2 kg inosanganiswa netii inodziya ine huremu hwe 0,2 kg. Tembiricha yeaizi = – 10 ^o C, tembiricha yetii inodziya = 40 ^o C. Kupisa kweaizi = 2100 J/kg C ^o , kupisa kwemvura = 4200 J/kg C ^o , kupisa kwemvura = 334.000 J/kg. Kana aizi netii inodziya zvakasanganiswa muchimiro chakavharwa, sarudza tembiricha yekupedzisira yemusanganiswa.

Kukurukurirana
Zvinozivikanwa :
Huremu hwechando (m es) = 0,2 kg
Huremu hwemvura inodziya yetii (m tii) = 0,2 kg
Kupisa kwemvura chaiyo (c mvura) = 4180 J/kg C^o
Kupisa kwechando (c es) = 2100 J/kg C^o
Kupisa kwekubatana kwemvura (L)_f mvura) = 334.000 J/kg

Mienzaniso mishanu yekutama kwekona uye kufamba kwemutsara mukufamba kwedenderedzwa

1. Vhiri rine radius ye30 cm rinotenderera daro rema radians gumi. Nhanho iri pamucheto wevhiri inofamba kusvika papi?
Kukurukurirana
Daro riri pakati pemucheto wevhiri nepakati pevhiri = nharaunda yevhiri.
Zvinozivikanwa kuti:
Nharaunda (r) = 30 cm = 0,3 metres
Kona (tit) = 10 radians

Kukurukurirana
F_1x =F₁ kusvika 60^o = (6)(0,5) = 3 N (yakanaka nekuti iri munzira yakanaka x)
F_2x =F₂ kusvika 30^o = (10)(0,5√3) = 5√3 = (5)(1,372) = -8,66 N (yakaipa nekuti iri munzira ye x isina kunaka)
F_1y =F₁ pasina 60^o = (6)(0,5√3) = 3√3 = (3)(1,372) = 4,116 N (yakanaka nekuti iri munzira yakanaka y)
F_2y =F₂ pasina 30^o = (10)(0,5) = -5 N (negative nekuti iri munzira ye "y" isina kunaka)
