Keep the negative value while squaring

Acc_Rocket(t) = (Thrust - weight - drag*Velocity(t)^2)./mass;

when the velocity is negative, the drag should be positive, but squaring the velocity makes the drag negative again, is there a way to make the velocity value keep its negative sign even when squared.

[James Tursa]

Change this

Velocity(t)^2

to this

abs(Velocity(t)) * Velocity(t)

thankyou, everythings working how it should now
