Impekumpeku

Kumchazandalo, impekumpeku yento iwuhlobo lwesidlakalasi leyonto enaso ngenxa yokuphekuzela noma umdiki wayo.

Kumchazandalo omdala, impekumpeku yento engampimpilizi enesisindo m ehamba ngejubane  v ibalwa kanje .Resnick, Robert and Halliday, David (1960) Physics, Section 7-5, Wiley International Edition 

Impekumpeku yento ilingana nomkhwishizo, isiphoqi esiphindwe nomkhwebuko, odingekayo ukufinyelela isivinini esibaluliwe. Ngenxa yokuzuza lesidlakalasi lapho ikhawuleza, isisindo sizoqhubeka nokugcina impekumpeku ngaphandle uma ijubane laso liguquka. Inani elifanayo lomkhwishizo lwenziwa yinto lapho iphungula ijubane layo kufika ekugculeni kwayo.

Isimiso sokulinganisa impekumpeku sibizwa ngokuthi umjulu (joule).

Kumchachiso wobucakathi obukhethekile, isibalo  siyicishelo elihle lempekumpeku kuphela lapho isivinini v singaphansi kwejubane lokukhanya.
