Abstract The purpose of this laboratory experiment is to experimentally calculate the value of acceleration due to gravity, g, and to calculate the percent error of g experimental versus g standard , taken as 9.81 m/s 2 . Students will learn how to properly use a magnetic drop box and target pad in order to determine free-fall times for both a small steel ball and a large ping- pong ball. Results yielded consistent data that g experimental for the small steel ball is 8.61 m/ s 2 . This value has a 12.23 percent error in comparison to g standard . Results also yielded consistent data that g experimental for the large ping-pong ball is 8.00 m/s 2 . This value has an 18.45 percent error in comparison to g standard . The higher deviation from the actual value of the large ping-pong ball than the small steel ball is most likely due to air resistance. Possible errors in this experiment include gross error, systematic error, and random error.
