At a certain point during its fall, the forces of drag and gravity become balanced, and the penny begins to travel at a constant rate. The faster a penny falls, the more air resistance it meets. Instead, it will encounter the drag of air resistance, which will counteract its acceleration. While a penny will be subject to gravity as it falls, it won't experience a continual acceleration. Velocity also comes into play in this scenario. Plus, at 19.05 millimeters (three-quarters of an inch) across, a penny's flat shape will cause it to flutter as it falls, making its trajectory more like a falling leaf than a potentially lethal arrow. At just 2.5 grams and 1.52 millimeters thick, a penny flung off a tall building isn't likely to kill someone walking below.
