Fitted line and correlation value   H (m) t 2  (s 2 ) Bryan Spelhaug Tues Lab 8:00am Experiment II: Free Fall Date: 9/14/10 Objective: In this experiment, we will be investigating how gravity (in general, the earth’s force on an object) moves a steel ball bearing from a specified height downward, toward earth’s surface, when released. Because the ball bearing is small in size and is going to be dropped relatively close to the earth’s surface, we will neglect the frictional force of air. After we have recorded all our data, we should be able to see that our steel ball has fallen close to the specified earth’s gravitational pull of 9.8m/s 2 . Method: For this experiment, we will be using a solid steel ball bearing and dropping it from a specified height (H) from a platform. Once released, the bearing will be in free fall and earth’s gravity will be acting on it in a downward direction. The ball will then hit a pad, which will stop the fall and record the time (T) it took to travel the distance from the platform on a computer. After the experiment, we noticed that when released, the ball bearing would slide against the clamps on the way down. This initial frictional force could have resulted in some data error. Also, even though the ball bearing is relatively small and arrow dynamic, air resistance is still acting on the bearing when in free fall. This will cause the bearing to
