Zvinhu zveKuroverana zvisina kusimba
Mukubatana kwechikamu che elastic (kusangana kwe elastic zvisina kukwana), mutemo wekuchengetedza momentum unoshanda , nepo mutemo wekuchengetedza kinetic energy usingashande. Munguva yekusangana, rimwe resimba re kinetic rinoshandurwa kuita simba reruzha, simba rekupisa, uye simba remukati. Kushandiswa kweshoko re elastic kunoratidza kuti mushure mekusangana, zvinhu zviviri hazvibatanidzi kuita chimwe kana kunamira pamwe chete, asi panzvimbo pezvo zvinosvetuka. Muenzaniso wekusangana kwe elastic zvisina kukwana kunosangana kwechikamu chimwe chete pakati pemabhuru maviri kana mabhora maviri ebhiriyadhi.
Muenzaniso wematambudziko.
1. Zvinhu A naB, chimwe nechimwe chine huremu hwe1 kg ne2 kg, zvinofamba zvakapesana nekumhanya kwe4 m/s ne2 m/s, uye zvinobonderana nenzira isina kunyatsosimba. Kana mushure mekubonderana, chinhu A chikafamba nekumhanya kwe2 m/s, chii chinonzi kumhanya kwechinhu B?
Kukurukurirana
Zvinozivikanwa :
mA = 1 kg, mB = 2 kg, vA = 4 m/s (semuenzaniso kurudyi), vB = -2 m/s (semuenzaniso kuruboshwe), vA' = -2 m/s
Akabvunzwa :vB'
Jawab :
Mushure mekuroverana, chinhu B chinofamba nekumhanya kwe1 m/s (semuenzaniso kurudyi) uye chinhu A chinofamba nekumhanya kwe2 m/s (semuenzaniso kuruboshwe).
