Do heavier objects fall on the ground quicker?
No. Physics can be and often is counterintuitive. Mass of an object doesn't affect the time of a fall. Different times are caused by air resistence and therefore are related to the shape. If we dropped a car and piece of paper in a vacuum they will touch the ground at the same time.
