A feather and a book are dropped in a vacuum which will hit the ground first?
BookAnswerIf you drop two objects of different mass, then they will fall at the same speed & rate. On Earth, the air will slow the fall of the paper due to air loads, so the book would hit the ground first. On the Moon, there is no or very little air, so they would both hit the ground at the same time.
What would touch the ground first a feather or an paperclip?
In a vacuum they would reach the ground at the same time (assuming they are released at the same time and from the same height). When not in a vacuum, however, air resistance is acting on both items - and so the paperclip would touch the ground first.
