Calculate the percent difference of free fall acceleration.

In summary, the formula for calculating percent difference of free fall acceleration is [(|New value - Old value|)/((New value + Old value)/2)] * 100. This allows scientists to compare the difference between two measurements of the same quantity, which can help identify experimental errors and improve accuracy. The percent difference can be negative if the new value is smaller than the old value, indicating a decrease in the quantity being measured. It can also be equal to 0 if the new value is the same as the old value, indicating no difference between the two values. Potential sources of error when calculating the percent difference include measurement inaccuracies, human error, and external factors like air resistance or variations in gravitational pull.

1. Calculate the percent difference of freefall acceleration for the light and heavier picket fence

Lighter Picket Fence - Mass 95.84 g | Acceleration 6.4141 m/s2
Heavier Picket Fence - Mass 128.16 g | 8.995 m/s2

2. Compare each of the values from the graphs to the accepted value of free fall acceleration using the percent error forumla.



3. Would I plug it in like this?
acceleration = acceleration m/s2 / 9.80 m/s2 so for #1 lighter picket fence it would be 6.4141/9.8

What is the formula for calculating percent difference of free fall acceleration?

The formula is:
Percent difference = [(|New value - Old value|)/((New value + Old value)/2)] * 100

What is the significance of calculating the percent difference of free fall acceleration?

Calculating the percent difference of free fall acceleration allows scientists to compare the difference between two measurements of the same quantity. This can help identify experimental errors and improve the accuracy of the results.

Can the percent difference of free fall acceleration ever be negative?

Yes, the percent difference of free fall acceleration can be negative if the new value is smaller than the old value. This indicates a decrease in the quantity being measured.

Is it possible to have a percent difference of free fall acceleration equal to 0?

Yes, if the new value is exactly the same as the old value, the percent difference will be 0. This indicates no difference between the two values.

What are some potential sources of error when calculating the percent difference of free fall acceleration?

Potential sources of error include measurement inaccuracies, human error, and external factors such as air resistance or variations in gravitational pull. It is important to control for these factors as much as possible when conducting experiments.
