Measuring "g" - Time of Fall Method

Data, Calculations, Conclusions

Data:

Distance fallen, d = ________ meters

Average time tave = __________ seconds

Calculating "g":

g=(2d)/t^2=

My calculated value of "g" = _______ m/s2.

Calculating My Percent of Difference:

The difference between my value of "g" and the accepted value, 9.81 m/s2 = __________ m/s2

%dif=dif/9.81

My percent of difference = _________ %

Calculating the Class' Percent of Difference:

The difference between the class' value of "g" and the accepted value, 9.81 m/s2 = __________ m/s2

%dif=dif/9.81

The class' percent of difference = _________ %

Conclusions:

1. Well, are you convinced that the acceleration due to gravity on Earth is about 10 m/s2?

 

2. What do you think caused the most error in your lab? Do NOT say "human error" - be specific!
