Free fal due to gravity

  1. May 25, 2009 #1
    i am doing yr 11 physics and have a question compare the velocity of an object as it starts with its velocity when it reaches the bottom of its flight?

    it would be equal or a greater fource of (9.8) gravity because you need to have the same amount of force or more to project it up for it to hit the ground
    ie' useing a pen instead of letting it go at 2m above the ground and letting gravity do the work, you need to be able to throw it up in the air, in order for it to drop and hit the ground at an equal velocity aka 9.8 or gravity. dose anyone agree?
    dose anyone know was this force is called or is it just a baisic one?
