simba
Equation yesimba ndeye F = ma
m = huremu (chiyero chayo chepasi rose ikirogiramu, kg yakapfupikiswa)
a = kumhanyisa (chikamu chayo chepasi rose chiri mamita pasekondi imwe chete, chakapfupikiswa m/s 2 )
F = simba (chikamu chayo chepasi rose ikirogiramu mamita pasekondi yakaenzana nemativi mana, yakapfupikiswa kg m/s 2 )
Velocity
Equation yekukurumidza ndeye v = s/t
s = daro (chikamu chayo chepasi rose imita, chakapfupikiswa m)
t = nguva (chikamu chayo chepasi rose ndechechipiri, chakapfupikiswa s)
v = velocity (chikamu chayo chepasi rose mamita pasekondi, chakapfupikiswa m/s)
nharaunda
Equation yenzvimbo ndeye A = lxl
l = kureba (chikamu chayo chepasi rose imita, chakapfupikiswa m)
A = nzvimbo (chikamu chayo chepasi rose chine mita yakaenzana nemativi mana, chakapfupikiswa m2 )
tembiricha
Tembiricha ihuwandu hwepasi. Chiratidzo chetembiricha ndiT uye chikamu chayo chepasi rose ndiKelvin, chakapfupikiswa ndiK.
Huwandu hwakatorwa pamwe chete nemayuniti avo epasi rose zvinoratidzwa nenhamba (1), (2), uye (3).
