Hello everyone, I have a question regarding energy fighting. Suppose you're flying a plane and you want to boom and zoom a target that is lower than you, flying at similar velocity. What is the optimal* way of diving and then zooming up again. *optimal wrt energy conservation. I'm aware of the fact that how much negative work friction does depends on the path, but what confuses me is that when the plane changes direction the force of friction changes, also iirc it depends on magnitude of velocity. P.S. Don't be shy to throw in some math :) Cheers.
