my first post but i had to get this out before i explode!! this has been bugging me to hell on this other forum i visit. there are a bunch of people insisting on "negative drag" is there such a thing? from what i understand drag is a force acting on an object moving through a fluid. and thrust is a force propelling the object through the liquid. so negative drag would be a force enacted on the object by the fluid in the direction of movement. so the object will be propelling itself wouldn't it? there is also another statement that says "thrust IS negative drag" thrust is constantly trying to over come drag so how can they be the same thing? so is it the same thing?
