Having an equal and opposite force is one of the primary laws governing structural engineeringmy college major! You said: "That doesn't matter. The work is the force applied times the distance traversed. NOWHERE in the definition of work does it say to subtract out the distance it would have gone if coasting. Please pay attention to the definition of work in your 7th grade science book." Apparently your mind stopped functioning in the seventh grade, PD! Because dunces like you, Coriolis, Einstein, and the majority of those teaching physics in academia don't realize that falling objects are adding new velocity distances to the accrued COASTING distances up to the point in question, doesn't negate the presence of those COASTING distances. Shut off the force of gravity and the object will continue to COAST at the last velocity, until it hits the ground. And nothing about your defies-the-Law-of-the-Conservation-of-Energy "Work" definition of KE can make COASTING not be the primary determinate of the distance of fall. You said: "Not at all. Kinetic energy, momentum, force, mass, are all DIFFERENT animals. That's why they have different names, John. Otherwise one name would do." One name WILL do! And that name is pounds! My $40.00 KE experiment invalidates Coriolis's KE = 1/2 mv^2, as does the Law of the Conservation of Momentum. Give it up, fellow. I've shot Coriolis and Einstein all to hell!
