# Picket fence free fall lab

Autoscale and examine your graphs. If your data is not consistent, repeat step 7. During the 6 runs, the picket fence was dropped from the same height and had an average acceleration of 9.

Complete four more trials of this experiment so that you have saved a total of five data runs. Collect a sixth data run where the Picket Fence is dropped through the Photogate from a higher starting point. The percent error between all five runs average and g is The additional information I need to determine the average speed of the Picket Fence as it moves through the Photogate is the amount of time need to go through it.

Therefore, the data collected was very accurate. The average of all the slopes was 9. The accepted value for g gravity is 9. After you take that result and multiply by The percent error between the average acceleration in the first five runs and the accepted value for gravity was only Recommended for High School.

Delete the Acceleration vs.

It is not a parabolic shape like that of the position vs. The purpose of the Picket Fence Free Fall Lab was to examine the acceleration of objects as they fall to earth.

Objectives Measure the acceleration of a freely falling body g to better than 0. The fence was thrown upward during the last run run 8 and had an acceleration of The average of these two runs is 9.

As a result, an object in free fall accelerates downward at a constant rate.Picket Fence Lab When the picket fence completely passed thru the photogate a graph of the acceleration vs. time and a velocity vs.

time graph would appear on our lab quest screen. Then we would look at our graphs and see if our velocity graph was a straight diagonal line of constant acceleration, if it was then it was a good trial run.

LabQuest. 5 Picket Fence Free Fall We say an object is in free fall when the only force acting on it is the earth’s gravitational force. No other forces can be acting; in particular, air resistance must be either absent or so small as to be. General Science L Lab.

Lab 2: Acceleration of Gravity Lab (Picket Fence) Object: To measure the acceleration of a freely falling body due to gravitational attraction. After Picket Fence Free Fall is loaded, a set of instructions of. The purpose of the Picket Fence Free Fall Lab was to examine the acceleration of objects as they fall to earth.

During free-fall the only force that should be acting upon the object is the earth’s gravitational pull ( m/s/s), therefore the velocity of the object should always equal m/s/s.

Lab {4} Free Fall Motion Abstract Within this laboratory students used a Macintosh computer, scientificwork interface, and photogate to measure the acceleration of gravity, g, in a free-fall experiment.
