Mostly for self interest: If I drop a 1lb weight from 15 ft (5m), what does it weigh when it hits the floor. If I have a 10lb weight and it drops from the same 5m shelf, does it weigh 10 times as much as my 1 lb weight from the 1st question? I may have the wrong terminology, but basically the 1lb weight in my hand weighs 1lb. If I through it in the air and catch it, it is heavier when it hits my hand, because of the force of gravity pulling it back down. If that fall is 5 meters, what is the weight the floor will feel when the object hits the ground.
