Emile Zimmerman Lab 3 Free Fall PHYS1110L Free Fall Lab 3 In this lab, we will investigate the effects gravity on free-falling objects regarding time and distance. We will be dropping virtual cannon balls from varying heights to see how long the object will fall. We will then take the time variables, calculate the 1/2t^2 value, and then plot the distance as x and the calculated value as y. We will find the line of best fit and use that to see if the value is close to that of gravity, which is 9.81. I believe we will find that our slope's value will be close to that of gravity because the item will be free falling without air resistance. Distance Fallen (m) Time to Fall (s) Calculated ½ t 2 value (s 2 ) 15 1.75 1.53 13 1.63 1.33 11 1.5 1.13 9 1.35 0.91 7 1.19 0.70 5 1.01 0.61 3 .78 0.30

Percent Error= [9.81-9.68] *100= 13% Conclusion: With this experiment, we were able to see that objects dropped all fell at a rate of around 9.81 meters per second. If you add together all the points from x plots and divide it by the total of the points from the y, you get 63/6.51=9.68 which is not far off from the value of gravity. The small margin of error of about 13% is most likely a random error as the sample pool is of only 7 data points. By increasing our data pool, any small errors should be eliminated.
