my dear , how did you get this formula of KE, KE=mv2/2 and the mass is equal to (rho)(volume ) so KE=(RHO)(VOLUME)(V2)/2 ,, I confused , can you explain more please

KE=mv²/2
m= ρV
kinetic energy per unit volume V
KE₁ =KE/V= mv²/2V =ρV•v²/2V = ρv²/2
m= ρV
kinetic energy per unit volume V
KE₁ =KE/V= mv²/2V =ρV•v²/2V = ρv²/2
