Question

EXTENSIONS 1. Use the distance vs. time graph and a parabolic fit to determine g. 2. Would dropping the Picket Fence from higher above the Photogate change any of the parameters you measured? Try it. 3. Would throwing the Picket Fence downward, but letting go before it enters the Photogate, change any of your measurements? How about throwing the Picket Fence upward? Try performing these experiments. 4. How would adding air resistance change the results? Try adding a loop of clear tape to the upper end of the Picket Fence. Drop the modified Picket Fence through the Photogate and compare the results with your original free fall results. 5. Investigate how the value of g varies around the world. For example, how does altitude affect the value of g? What other factors cause this acceleration to vary at different locations? How much can g vary at a location in the mountains compared to a location at Trial 1 2 3 4 5 6 Slope (m/s²) 9,774 9,742 9,770 9,756 9,741 9,734 Minimum Maximum Average Acceleration (m/s²) 9,734 9,774 9,7528 Acceleration due to gravity, g 9,75 ± 0.02 m/s² Precision 0,205 %
