Izinto Zokungqubuzana Ezingenasici
Ekungqubuzaneni okungaphelele (ukungqubuzana okungaphelele), umthetho wokulondolozwa komfutho uyasebenza , kanti umthetho wokulondolozwa kwamandla e-kinetic awusebenzi. Ngesikhathi sokungqubuzana, amanye amandla e-kinetic aguqulwa abe amandla omsindo, amandla okushisa, kanye namandla angaphakathi. Ukusetshenziswa kwegama elithi i-elastic kubonisa ukuthi ngemva kokungqubuzana, izinto ezimbili azihlangani zibe yinye noma zinamathele ndawonye, kodwa kunalokho ziyagxuma. Isibonelo sokungqubuzana okungaphelele ukungqubuzana okunobukhulu obubodwa phakathi kwamamabula amabili noma amabhola amabili ebhiliyadi.
Isibonelo sezinkinga.
1. Izinto A no-B, ngayinye enesisindo esingu-1 kg no-2 kg, zihamba ngezindlela eziphambene ngesivinini esingu-4 m/s no-2 m/s, bese zishayisana ngendlela engaguquki kahle. Uma ngemva kokushayisana, into A ihamba ngesivinini esingu-2 m/s, iyini ijubane lento B?
Ingxoxo
I-Diketahui :
mA = 1 kg, mB = 2 kg, vA = 4 m/s (isb. ngakwesokudla), vB = -2 m/s (isb. ngakwesobunxele), vA' = -2 m/s
Kubuziwe :vB'
Jawab :
Ngemva kokushayisana, into B ihamba ngesivinini esingu-1 m/s (isibonelo ngakwesokudla) bese into A ihamba ngesivinini esingu-2 m/s (isibonelo ngakwesokunxele).
