1/2? x Rhox (V squared) is derived by integrating the rate of change of the momentum.

Since the momentum is Rho x V, if you integreate it (using integral calculus) you get the 1/2 x Rho x (V squared).

it is that the area? under the momentum vs V curve is calculated by the formula.

The Purple and Greay parts confuse me. (Gentle reminder, Why 1/2)

Please remember I want to be but curently I am so could you dumb it down a little(Lot) for me.

Edit 1/2 hour later

Or is it
