Free Fall Students are to demonstrate that the acceleration of an object in free fall is constant, and to determine the numerical value of that acceleration. By: Clinton Skvarek Partners: Choongnam Onoe, David Chen TA: Cheng “Chester” Xu Section: 75529 Monday (9:40-11:30)

Objective: To measure the acceleration of free fall, " g ." Procedure: Part 1: Using a tape measurer, measure the height, y , of where the two objects will be released. Then drop both objects, a solid ball and a wiffle ball, from the building and record the time, t , it takes to fall to the ground. Repeat the process 10 times in order to get an analytical value of t. By using the propagations of error and the equation, y=1/2 gt , the value of gravitational acceleration, g , can be evaluated. Part 2: Position the photogate carefully so that you may drop the picket fence through safely. Press the “Start” button and pass the fence passes through, catching it before it hits the rubber pad below. When 5 seconds have passed,

Results: Part 1: t (s) t (s) y (m) y (m) g (m/sr) g (m/sr) 1.48 .03 9.5 0.02 7.57 .268 1.70 .02 9.5 0.02 5.87 .143 Part 2: g (m/sr) g (m/sr) 9.8 .04 Data Analysis: Conclusion: With no air resistance an object accelerates at 9.81 m/si . During the experiment, both objects, the solid ball and wiffle ball, had slower acceleration rates than anticipated. The reason for the wiffle ball to accelerate slower was due to the air traveling through the holes in the ball that created resistance. Though the solid object had no holes, it still accelerated slower than the rate of free fall. This was due in part to experimental error. Perhaps the stopwatch was not started at the precise moment the ball was dropped. If there was no air, both objects would have ideally gotten 9.81 m/si ....
