The arrow when shot off the groundwill drop more then an arrow shot out of a tree because gravity is not affecting an arrow being shot downward.
Jim, you're wrong there. Gravity is a constant. It doesn't matter that the arrow is being shot pointed at a downward angle. Gravity will have the same affect on an arrow shotat a target 20 yardsaway from 15 feet upas it does if you shot it from the ground at a target 20 yards away. Either way, the arrow is traveling 20 linear feet (level, straight line distance). True, the actualpath of travel is a couple of feet longer because of the elevated position, but that won't make a difference thatyou can measure. Trust these guys. They know what they're talking about.
