Uniformly Accelerated Motion Graphs Please make two graph using the data attached. Graph 1 is based on the uniformly accelerated motion laboratory report data that is attached and graph two is a linear regression graph based on the date in data set #16 which I circled in an attached photo. Please also answer questions 1-6 And questions 6-9. All attached. 4) What is the most obvious, simple change (using the same equipment) that you could make to the
experimental procedure to increase the accuracy of the g you determine? (Hint think about (1)
5) On graph (1), what does the slope of the line tell you about the velocity of the ball? Be thorough!
6) On graph (2)
a) What does the slope of the line tell you about the acceleration of the ball? Be thorough!
b) Calculate g from the freefall data and the % error (in comparison to 9.81 m/s?) using the results
from the linear regression calculation.
c) What do the values of the y-intercept and correlation coefficient (T) tell you?

UNIFORMLY ACCELERATED MOTION – FREE FALL
Questions
1) How would you expect the height from which one drops the ball to affect the accuracy of the
experimentally determined g? What things cause this variation in accuracy, and exactly how do they
cause the variation? What trend in g should you observe as drop height increases?
2) How would your experimentally determined g be affected if the height of the object to be dropped were
measured from the lower trip plate to the top of the object instead of its bottom? Would this be a
systematic or random error, and exactly how would the data indicate this? Explain.
3) Though in this experiment air resistance is considered negligible, suppose that it were not. How would
this affect your experimentally determined g? Would this be a personal, systematic or random error?
Explain
