Free-Fall Name: Experiment: A small metal ball is dropped from rest (initial velocity is zero). The timer records how long the ball is in the air. Using the following data, we can calculate the acceleration of an object in free-fall.

Find the average time for each trial. b. Calculate the final velocity for each trial. Use the kinematic equation that does not contain acceleration, specifically: X, - X; = 1/2 (V, +V,) t and use the average time for t. c. Graph the final velocity versus the average time. (see graph paper) d. Calculation of the free-fall acceleration by finding the slope of the graph. a = (12 - y1) / (X2 - X1) Questions: 1. What is the "standard" value for the free-fall acceleration of an object near the surface of the earth? 2. What is the free fall acceleration as determined by your experiment? 3. Calculate the percent difference between your experimental result and the standard value. % Difference = { lexp - theory| / |theory| } x 100
