Zvinyorwa zvefizikisi nezvezviitiko zvechisikigo nezvimwewo zvine chekuita nefizikisi.
Kukurumidza (acceleration ) inhamba yevector, huwandu hwemuviri hune hukuru negwara. Chiratidzo chayo i ( acceleration ) . Chiyero chayo chepasi rose mamita pasekondi imwe chete, chakapfupikiswa m/s 2.
Avhareji yekukurumidza
Muenzaniso wematambudziko.
Mota inotanga yakamira kwemasekonzi mashanu yobva yaenda kumabvazuva ichimhanya 10 m/s. Sarudza avhareji yekumhanya.
Kukurukurirana
Kana ukasundira bhuku patafura kusvika rafamba, unenge uchishanda pabhuku. Kana chinhu chikawira pamusoro penyika nekuti chadhonzwa nesimba regiravhiti , simba regiravhiti rinoshanda pachinhu chacho. Kusiyana neizvi, kana ukasundira chinhu nesimba rako rese kusvika wanyorova nedikita asi chinhu chacho chikasafamba, unenge usina kushanda pachinhu chacho. Muhupenyu hwezuva nezuva, unonzi wakashanda nesimba kana kuti wakashanda nesimba uchisundira chinhu, asi maererano nefizikisi, hauna kushanda pachinhu chacho nekuti chinhu chacho hachifambi (chinhu hachichinji nzvimbo).
Zvinhu Zvinokurudzira zveAngular
Chinhu chinoita kufamba kwakatwasuka ine simba rinogona kuverengerwa uchishandisa fomura:
p = mv
Information :
p = momentum (chikamu chepasi rose ikirogiramu mita / yechipiri, chakapfupikiswa kg m/s)
m = huremu (chikamu chepasi rose ikirogiramu, kg yakapfupikiswa)
v = kumhanya (chikamu chepasi rose imita / sekondi, chakapfupikiswa m/s)
Huwandu hwemuviri mukufamba kwekutenderera hwakafanana nehuremu (m) mukufamba kwakatwasuka ndihwo nguva yekusaita basa (I). Huwandu hwemuviri mukufamba kwese kwakafanana nevelocity (v) mukufamba kwakatwasuka ndihwo kumhanya kwekonaSaka, chinhu chiri kutenderera chine simba rinogona kuverengerwa uchishandisa fomura:
Nguva Yezvinhu Zvisina Kushanda
Kune zvinhu zviviri, chimwe chine huremu hudiki uye chimwe chine huremu hukuru. Ndechipi chinhu chiri nyore kufambisa kana chikasundidzirwa nesimba rimwe chete? Chokwadi chinoratidza kuti zvinhu zvine huremu hudiki zviri nyore kufambisa pane zvinhu zvine huremu hukuru. Saka saizi yehuremu hwechinhu ndiyo inosarudza saizi yekumhanya kwechinhu kana simba rikashanda. Kana mukufamba kwakatwasuka, huremu hwechinhu hunoratidza kana chinhu chiri nyore kana kuti chakaoma kufambisa (kukurumidzisa) saka mukufamba kwekutenderera, nguva yekusashanda kwechinhu ndiyo inosarudza kana chinhu chiri nyore kana chakaoma kufambisa.
Chinhu Chenguva Yesimba (Torque)
Maoko eSitayera
Funga nezvechinhu chinotenderera, senge gonhi. Kana gonhi rikavhurwa kana kuvharwa, rinotenderera. Hinge inobatanidza gonhi nemadziro inoshanda sechikamu chekutenderera.
Mufananidzo wegonhi rinoonekwa kubva kumusoro. Funga nezvemuenzaniso apo gonhi rinosundirwa nemasimba maviri, uko masimba ese ari maviri ane hukuru uye gwara rakafanana; gwara resimba rakanangana negonhi.
Kare makadzidza mutemo wechipiri waNewton unoratidzwa kuburikidza ne equation:
Iyi equation inotsanangura hukama huripo pakati pesimba rinobuda, iro rinozivikanwawo sesimba remagetsi, uye huremu nekukurumidzisa. Simba rinobuda rinoshanda pachinhu chine huremu rinoita kuti chinhu chikurumidzise.
Panguva ino tichataura nezveimwe mhando yemutemo wechipiri waNewton, unotsanangura hukama huripo pakati pesimba rinobuda uye shanduko musimba.
Kumhanya inhamba yevector, nepo velocity iri nhamba yescalar. Kumhanya kune hukuru negwara, nepo velocity ine hukuru chete. Chiyero chepasi rose mamita pasekondi, chakapfupikiswa m/s kana ms -1 . Chiratidzo chayo ndi v ( velocity ).
Avhareji yekumhanya uye avhareji yekumhanya
Dzidzawo mienzaniso yekumhanya kwetangential uye kumhanya kwekona.
Kana chinhu chikatenderera newachi uye chikapedzisa kutenderera kamwe chete (360o) musekondi imwe chete, ipapo kumhanya kwekona kwezvikamu zvese zvefeni kutenderera kamwe chete/kwechipiri = 360 o /kwechipiri = 6,28 radians /kwechipiri uye kutungamira kwekona kwekona kuri newachi. Kana radius yefeni iri 20 cm, mupendero wefeni unofamba mudenderedzwa nekumhanya kwe (2)(3,14)(20 cm) / sekondi imwe chete = 125,6 cm / s = 1,256 m / s. Poindi imwe chete kubva ku axis inofamba mudenderedzwa nekumhanya kwe (2)(3,14)(1 cm) / sekondi imwe chete = 6,28 cm / s = 0,0628 m / s. R diki, kumhanya kudiki. Mukufamba kwedenderedzwa , kumhanya kunowanzonzi kumhanya kwekona. Kunonzi kutenderera nekuti kutungamira kwekumhanya kunogara kuri kutenderera munzira yakatenderera.
Kunzwisisa Kureba
Kureba kwenzira inofamba nechinhu. Kureba kwenzira inotsanangurwa nechiyero, huwandu hwemuviri hune hukuru chete uye husina gwara. Chiyero chepasi rose chedaro imita, yakapfupikiswa m. Chiratidzo chedaro ndi s.
Tsanangudzo yeKudzingwa
Kuchinja chinzvimbo chechinhu. Kuchinja chinzvimbo inhamba yevector, huwandu hwemuviri hune hukuru uye gwara. Kutungamira kwekuchinja kunogona kuratidzwa segwara guru (kuchamhembe, kumabvazuva, kumaodzanyemba, kumadokero, nezvimwewo) kana kushandisa mazwi ekuti kuruboshwe, kurudyi, kumusoro, kana pasi.
Mutemo wekuchengetedza angular momentum akataura kuti kana nguva yesimba inoguma muchinhu chakasimba chiri kutenderera kukosha kwacho kuri zero ipapo simba rekona Chinhu chakasimba chiri mukufamba kwakatenderera nguva dzose. Fomura yemutemo wekuchengetedza angular momentum inogona kuwanikwa nemasvomhu nekushandura fomura yemutemo wechipiri waNewton wekufamba kwe angular momentum.
