http://www.sacred-texts.com/earth/za/za21.htmAccording to the above link, ENaG says that Newton's Law of Motion (An Object in motion stays in motion specifically) doesn't exist. Why?
Well, he says that
"By the time the ball has arrived at D, the ship will have reached the position, S; and now, as the two forces will have been expended, the ball will begin to fall, by the force of gravity alone, in the vertical direction, D, B, H; but during its fall towards H, the ship will have passed on to the position S, leaving the ball at H, a given distance behind it."
An object in motion will stay in motion. An object at rest will stay at rest.
According to the book, the forward motion stops when the ball hits the apex of it's trajectory. It also claims that it's trajectory is a diagonal line, which is odd since the forward motion is constant and the vertical is an acceleration down of 9.8M/2^2 This, as anyone should be able to tell you, is a curve, not a straight line.
So... any Flat Earthers want to try and defend this? (besides Tom who is going to try anyway)?
