  1. I have questions about the power and force equations. According to the power equation shown in the video, power seems to be a function of v^3. If you increase speed by 2 then power requirement increases by 8. But that's weird. Best illustrated in a plane. If you fly 2 times the speed them aerodynamic pressure is 4 times higher, and the required thrust is 4 times higher too. Which means power is increased by 4, not 8. Hence, power seems to be a function of v^2 here. Could you explain what's happening?
