I am very well aware that winglets reduce induced drag and the theory behind it. Please have a read of all my posts again. I was responding to a post that was saying that winglets produce thrust. I simply responded that they don’t, they produce a small component of lift in the direction of flight.
I think you will also find that Kinetic energy is the force which keeps the a/c in forward motion conducting a glide and as a result lift results accordingly.
Please tell me you are kidding with this statement??
Arm out the window
You are correct. Weight is the force. KE is not a force and doesn’t belong in a forces diagram.
