When objects are in true free fall, they will eventually reach their terminal velocity when the downward force from gravity and the upward force from air resistance are equal. This explains the curve in the graph: because of the constant acceleration produced by the force of gravity, the velocity of an object will get increasingly faster. The graph you create will show that the longer the meter stick falls, the faster it ends up moving. Human reaction time is approximately 0.25 seconds which, for the majority of people, is not fast enough to catch a dollar bill. Your calculated acceleration should be close to 9.81 m/s 2. Graphing results will show that distance traveled is in proportional to the square of the time spent falling. Use the above equation to calculate how long it will take for the length of the dollar to pass through your fingers. Repeat the experiment with a dollar bill.
