Mark A.M. Kramer on 20 Oct 09THIS IS FOR BATO! "During a sky dive (which is not free fall - free fall implies there is only the gravitational force acting on the object), there are essentially two forces to consider: gravity and air resistance. The air resistance is a force that depends on several things: * The cross sectional surface area of the falling object * The shape of the falling object * The density of the air * The speed of the falling object"
