The results of this experiment were extremely consistent. The fence was thrown upward during the last run (run 8) and had an acceleration of -6.470 m/s/s, showing that the force of gravity was slowing it down as it traveled upward. This proves that none of these circumstances had any affect on the acceleration of the fence and that only gravity influenced its fall. Even runs during which the photogate was dropped from a higher height or thrown downward (runs 6 and 7), had an average acceleration of 9.741 m/s/s. During the first 5 runs, the photogate was dropped from the same height and had an average acceleration of 9.762 m/s/s- which is extremely close to the expected value of 9.8 m/s/s. The results of the experiment confirmed the theory that objects will fall with a constant acceleration equal to g (9.8 m/s/s). In this lab the picket fence was dropped repeatedly through a photogate connected to Logger Pro, which allowed the fenceвЂ™s acceleration and velocity to be recorded and graphed. During free-fall the only force that should be acting upon the object is the earthвЂ™s gravitational pull (9.8 m/s/s), therefore the velocity of the object should always equal 9.8 m/s/s.

The purpose of the Picket Fence Free Fall Lab was to examine the acceleration of objects as they fall to earth. This is due to the fact that the fence is fighting gravity as it is thrown upward, as opposed to free falling because of the pull of gravity. This is 16.232 m/s/s less than the average acceleration of the first five runs.

The average acceleration of the fence when thrown upward (run 8) is -6.470 m/s/s.

This means that the distance the fence fell and how hard is was thrown had virtually no perceivable effect on the fenceвЂ™s velocity. The average of these two runs is 9.741 m/s/s, making it 0.021 m/s/s less than the average of the first five runs. The acceleration when thrown downwards (run 7) is 9.724 m/s/s.

The acceleration of the fence dropped from a greater height (run 6) is 9.758 m/s/s.

This equation is similar to the equation that calculates the distance traveled, meaning the solution would be how far the fence traveled. When quadratic fit was performed, the A value was 4.883, the B was 1.472, and the C was -4.65x10^-6.The percent error between all five runs average and g is -0.388%. The percent error between run 1вЂ™s calculated acceleration and g is -1.398%. The accepted value for g (gravity) is 9.8 m/s/s, and all the calculated accelerations from the first five runs are within.021 m/s/s higher than the slope estimated from the velocity vs. This makes sense considering this value is only. Run 5вЂ™s average acceleration, according do its acceleration vs.The average of all the slopes was 9.762 m/s/s. The maximum slope was run 4вЂ™s 9.843 m/s/s. The minimum slope for the first five data runs was run 1вЂ™s slope of 9.663 m/s/s.To avoid damaging the Picket Fence, make sure it has a soft surface (such as a carpet) to land on.

The entire length of the Picket Fence must be able to fall freely through the Photogate. Fasten the Photogate rigidly to a ring stand so the arms extend horizontally, as shown in Figure 1.

Logger Pro will make two graphs of displacement/time and velocity/time, by solving the slope of the graph we will have the acceleration of gravity.ДЎ. As we drop 'a clear plastic with evenly spaced black bars on it, called the Picket Fence' through Photogate, it will calculate the amount of time the light beam from the device being blocked and send the data to Logger Pro, which we used in Lab 1. In this experiment, we use a device called Photogate, which has a beam of light travel from one side to the other. Today we have an experimentВ toВ examine the motionВ of a falling object and measureВ the acceleration of Earth's gravity: The basic of the experiment isВ to haveВ an object 'free fall' and then measure the acceleration and give out the result. InВ Chapter one: Kinematics, one dimension,В we have focused inВ the movement of an object due to gravity.
